Jet furnace from a gas cylinder. How to make a brazier from a gas cylinder? The order of work and photos of finished projects Do-it-yourself oxygen cylinder

My name is Rostislav, I am 37 years old and I am a builder with twelve years of experience. Today we will talk with you about outdoor recreation. And nature, as you know, is friends, family and barbecue. To cook meat in nature, you can use all sorts of improvised means - bricks or sticks, or you can do it yourself beautiful barbecue from a BBQ gas bottle and surprise everyone. If such a brazier will stand in the yard, then it will immediately attract the attention of your guests and neighbors. Also, this brazier is compact enough to take it with you in the trunk. passenger car.

Making a brazier with your own hands will not take much time and labor, you just need to be able to use a grinder and a welding machine or ask a specialist. All photos and drawings of such a brazier from a gas cylinder are attached.

So what do we need for this:

8. Piece of chalk.
9. Clamp clamp.
10. Square.

So: Let's get to work.

To start the robots, we need an empty gas cylinder with a capacity of 50 liters. Such cylinders were previously used on the farm in the private sector. It consists of three parts: a valve, a reservoir tank and a cylindrical stand.

Marking the gas cylinder for barbecue

A gas cylinder, even if it is empty, is VERY DANGEROUS, therefore it is strictly forbidden to use open fire near the cylinder, as well as cause mechanical damage. It could cost your LIFE!!!

The fact is that the so-called gasoline is used in the admixture of natural gas, which is designed to distinguish the smell of gas. Gasoline, in itself, is the same combustible gas that is absorbed into the metal, and even if the cylinder is empty during the test, gasoline vapors are still present in it. Therefore, I repeat once again, you need to work with a gas cylinder very carefully, without neglecting the safety rules.

Let's get back to our markup. If you look at the cylinder, you can see that a welding seam runs along its entire height. We take this seam as the first line of the beginning of our markup. If you take a tape measure and measure the circumference of the balloon ( circumference - this is the extension of the outer or inner line of the circle.) it will be equal to 96 cm. From this line - the seam, with the help of a tape measure we mark 24 cm in each direction. We mark at the top and bottom of the balloon and draw a line with chalk. Then we retreat from this seam line in each direction by 10 cm. and also draw a line with chalk - this is our line for the air supply holes.

Next stage: we determine where we will have the front side of the brazier and add to the back line that we marked, retreating 24 cm another 10 cm. This will be our cutting line. There are also welded seams on the bottom and top of the cylinder, which go around the circle of the cylinder. The distance between them is standard 61 cm. We retreat from these seams 3 cm, put two points each and draw a line. The fact is that in the middle of the cylinder along the circumferential seams there is a seam reinforcement tape and we need not to damage it.

Thus, we have drawn a cover for the future barbecue, the width of which will be 38 cm (96-24-24-10), and the length - 55 cm (61-3-3) as indicated in the drawing.

Preparing for cutting a balloon for barbecue

Before making the first cut, you need to protect yourself. To do this, you need to fill the bottle with water. How it's done? Before you start the robot, you need to make sure that the tank is empty. To do this, open the shut-off valve, which is located at the top of the cylinder and by ear determine if there is a hiss of gas. Then, in the same way, with the tap open, turn it down with the tap so that all the available liquid flows out from the inside.

The stopcock is made of bronze alloy, and bronze is a very soft metal to work with. Therefore, we take a hand saw for metal and at the bottom of the faucet - where it is twisted into a cylinder, we cut off the faucet completely. We have formed an inlet into which we can insert a watering can or hose to fill with water. You need to understand that the water that will fill the balloon will displace the air saturated with gasoline, so it is forbidden to smoke or use open or hidden fire during this operation !!!

The bottle must be completely filled with water. After that, we make a cork. This is where a cork stopper from a bottle of wine or something like that can help us. Having slightly tucked it, we hammer it tightly with a hammer into the hole. Then we lay the balloon in a horizontal position and make a cut.

Making a mangal cover

When starting to cut the cylinder, it must be taken into account that water will flow during the through cut. Therefore, we remove the electrical wires as much as possible and it is better to cut on an inclined base, controlling the flow of water. Yes, I agree that the event is "wet", but this is the safest method of cutting a gas bottle.

We make a cut with a grinder along our marked lines. They are marked in red on my diagram. The disk for the grinder must be chosen thicker, at least 1.6 mm. The width of the cut is compensated by the expansion of the metal when heated. It must be remembered that the metal on the cylinder “tenses” during welding and, when cutting, can wedge the disc a little, so we use wedges. At the same time we cut threaded connection for stopcock cover. It is located on top of the balloon.

So, when the brazier cover is cut out of sheet metal, cut out strips 3 cm wide, one meter long - three pieces, and weld along the perimeter of the lid so that the edge of the strip protrudes 1.5 cm beyond the edges of the lid. With the help of clamps, periodically pressing the strip to the lid. This will prevent the lid from falling into the middle of the grill. We also weld the handle. We clean the welding places with the help of a grinder and a cleaning disk. After installing the cover on the cylinder, you need to center it and weld the curtains, having previously retreated the same dimensions from the edges of the cylinder.

From the side of the top of the gas cylinder, where we cut off the threaded connection, you can make a valve that will regulate the smoke output, that is, the degree of smoked meat. We cut out three strips of 10 cm each from sheet metal and bend the edge with pliers or in a vice so that we get a corner and scald around the perimeter of the hole, observing the evenness of the dimensions. And from the same sheet metal we cut out the valve itself, making an allowance of no more than 1 cm so that there is free play.

From the bottom of the gas cylinder there is a cylindrical stand, which we also cut off with a grinder. It is welded with a burst seam around the circumference of the cylinder.

Leg welding

The legs or stand can be welded from improvised material, can be made collapsible or stationary, with or without tables. You can even use the stand from the old sewing machine, but I managed the most economical option.

We take a corner and cut off two blanks of 14 cm each, we find a longitudinal welding seam on the cylinder, which we took as a reference line. We put the cylinder on a horizontal platform or on a table, so that the seam is at the bottom and, placing a corner parallel to the platform, weld it at a conventional distance from the edge of the cylinder so that the center of the corner shelf coincides with the welding seam of the cylinder. We do the same on the other side. So we got the base for attaching the legs. And now we look if we need to make the legs not separate from the barbecue, then we simply cut a 30x30 pipe or a corner in length, which will be convenient for us for the height of the barbecue - about 50 to 70 centimeters. Next, weld it to the corner, which is on the cylinder.

And if we plan to make a collapsible structure, then we also cut the blanks into legs, but do not weld them to the corner, but drill holes of about 8 millimeters in the upper part of the leg and in the corner welded to the cylinder. Thus, we get a collapsible design: the cylinder is separated from the legs and can easily fit in the trunk of a car for going to a barbecue in nature. It should be noted that the legs must also be mounted observing the identity of the dimensions and diagonal of the structure. In the lower part of the legs, it is desirable to weld the support patches, after cutting them out of sheet metal and placing the brazier on the legs on a flat area. This is necessary so that the brazier does not fall into the ground under its own weight and has good resistance to tipping over. For more convenient transportability, you can mount small wheels on two legs.

Installation of a chimney for a barbecue

The chimney is an optional element of our homemade barbecue, but it gives a more aesthetic appearance and works as a regulator of the degree of smokedness of the cooked product.

For the manufacture of this element, a pipe with an outer diameter of 90m is quite suitable. and 70 cm long. Since the factory corners have a very smooth turn, sharp corner you can weld it yourself, after cutting out a segment of the pipe, which is marked from the turning point with a square in two directions at 45 degrees around the circumference of the pipe. Having cut a segment with a grinder, we bend the smaller part to the larger one, with the help of a corner we check the angle of 90 degrees and weld them in place. After that, we expose the pipe to the place of welding, where we installed the damper, and weld the pipe well in a circle. It should be noted that each seam must be cleaned with a cleaning disk. So it acquires a more aesthetic appearance and the quality of the weld is clearly visible.

When the pipe is welded, install a protective cap. It is fixed with a clamping bolt.

Places for skewers and grill nets for barbecue

For a comfortable arrangement of skewers on the back wall of our barbecue, we drill holes. The skewer has a pointed part in front, which clearly enters these holes and holds steady there. As we see in the photo above, six skewers are conveniently placed on the grill. To do this, we make a markup, stepping back from the top edge of our cutout of the brazier cover, 10 cm. down on both sides, put marks and draw a line with chalk. This is the hole level. Then retreating from the edge of the radius cut 4 cm. and mark the drill. And then every 10 cm we put the same marks. Using a drill and a drill, we drill holes according to the marks. To do this, we first use a thin drill, for example, 4mm, and then we drill it with a 10mm drill, and at the end we chamfer the hole with a 12mm drill. or round file. WITH front side brazier we also make markings on the upper face of the brazier and cut out the grooves for the skewers with a grinder. When this operation is completed, cover the brazier with a lid and transfer the marks of the places where the cutout is made to the brazier cover. We do the same cutting. This must be done so that when the skewers are installed, the brazier lid closes more tightly.

You can also make seats for the grill - a grid. To do this, we just need to weld metal shelves between the holes for the skewers. From the corner we cut out workpieces 3 cm long, and weld them to the walls of the brazier, having previously marked the places of welding so that the grid has six points of support along the perimeter of the brazier. We clean the places of welding and cut off sharp corners.

To cook meat on a grill mesh, you can use a stainless mesh, with a cell of 10x10, or 15x15mm, pre-cut to fit the perimeter seats as in the photo below.

Air holes

In chapter "markup", we marked out the line for the air supply. This line is at a distance of 10 cm from the longitudinal weld on both sides. Then we take a drill with a diameter of 8mm. and drill those holes. I believe that the hole diameter of 8mm is enough for air supply, since a larger diameter can affect the spillage of burning coals during the burning of heat in the grill. These holes can be drilled both at the beginning of our barbecue assembly and at the end of the work.

You can also add handles on the sides of the barbecue - for ease of movement around the territory.

Barbecue painting

Braziers are operated on outdoors. Therefore, after installing the device, we immediately determine what paint to paint the barbecue.

The coating will protect it from atmospheric precipitation, high humidity and temperature changes. Of course, the brazier should be painted only on the outside. Inside it, when used, the temperature is too high for any type of paint.

The choice of coverage must be approached very carefully.

It must meet the following requirements

1. The paint must contain modifiers that protect the metal from rust. The finish should not melt, i.e., have a high fire resistance. The instruction on the paint label must indicate its heat resistance of at least +500 °. Even better, if this figure is + 800 °.
2. It should be borne in mind that the barbecues are used for cooking. Based on this, the coating should be environmentally friendly and safe. It should not react with any substances.

Paints are commercially available in two types: aerosol and just liquid paint.

Aerosol paint is sold in a can, in which there is air pressure, and when painting, we simply direct the jet of the can onto the surface to be painted at a distance of 20–30 cm. And liquid paint in a can is applied with an ordinary paint brush.

First you need to clean our brazier from dirt and dust, check the cleaning of all welds, and most importantly: clean the brazier and the brazier cover from old paint. The fact is that gas cylinders are not painted with heat-resistant paint, but applying heat-resistant paint to non-heat-resistant paint threatens with subsequent melting and burning out of the lower layer of paint, which will entail unpleasant consequences.

It should also be borne in mind that only the brazier itself can be painted with heat-resistant paint, the area of ​​\u200b\u200bwhich is not more than 1.5 m 2. Therefore, one bottle will be enough for us. And the legs and available additional elements can be painted with ordinary paint for metal. This will slightly reduce costs, since heat-resistant paint is much higher in price than ordinary metal enamel.

During and after painting, dust should not get on the painted surface and work should be carried out at a temperature of at least 10 degrees Celsius in calm weather.

On this, our work on making a brazier from a gas cylinder can be considered finished, but on my own behalf I want to add that there are a lot of schemes and examples on the Internet for the manufacture of this type of brazier. However, a brazier from a gas cylinder can be unique in its kind when you make it yourself and show imagination to implement projects for additional structural elements. This is how I got a brazier from a gas cylinder with my own hands:

Write questions and additions below. I will be glad to hear your opinion.

We also recommend you:

But really, what can be done from a gas cylinder with your own hands? It has been so customary since the times of the Soviet Union that many products can be fundamentally recycled and new designs can be obtained from them that will perform completely different functions. As it turned out, a lot can be done from a gas cylinder and, mind you, everything will be done with your own hands.

balloon stove

First of all, when you are looking for an answer to the question of what can be done from a gas cylinder with your own hands, a potbelly stove comes to mind. Such a unit has many advantages, as well as in the very principle of installation. Firstly, the thickness of the walls of the gas cylinder is 3 mm, and this is quite enough so that the potbelly stove from it does not burn out in the first season of operation. Secondly, it will take quite a bit to finalize the gas cylinder - the stove is made in one day with your own hands. The third advantage lies in the huge choice of designs: you can make a stove from one cylinder or two, a vertical design or a horizontal one. Your own fantasy or tips from the Internet - and you can make a product out of a gas cylinder that will help you out in a cold winter.

Disadvantages are also present. Or rather, these are not even shortcomings, but features that must be taken into account so that they do not turn into shortcomings. For example, it is necessary to remove the paint from the outside of the parts from the cylinder before the first firewood fire. Otherwise, the paint will begin to fade and fill the room with acrid smoke. It is also MANDATORY to take care of fire safety. The walls of the stove from a gas cylinder can heat up red-hot and this is fraught with many troubles. It may seem to you that such heating is only a plus, because it will be warm inside the room. But everything that can flare up from such strong heating will certainly flare up if it is too close to the potbelly stove. And the walls of the room itself need to be taken care of: in our workshop, the cinder block wall cracked vertically over its entire height after just a few evenings of use. What can be done to protect the wall: install the stove at a distance from it, protect it with a galvanized screen mounted on the wall at a short distance from it, or heat the potbelly stove in moderation. The latter, by the way, is not the best - it will be difficult to “guess” the optimal amount of firewood. And most importantly: a stove from a gas cylinder with your own hands (and even strangers too) will cool down very quickly. As long as the fire burns inside, while firewood is thrown up, it will be warm. But as soon as the firewood burns out, the stove instantly cools down. The insulated walls of the room where such a potbelly stove will be used, and the elimination of even minimal gaps in the area of ​​\u200b\u200bwindows, doors or gates of the room, will help.

Feeders for animals and birds

This is another option for what you can do with your own hands from a gas cylinder and at the same time get excellent quality. Such feeders seem to be, if not eternal, then 100% durable. The gas cylinder is cut along its axis and you get two halves, each of which will be an excellent feeder for pigs, sheep or a bird drinker. It remains only to weld the stand, since the lower part of each of the halves will be semicircular and, of course, will not stand on the ground. You can also cut off the top and bottom of the cylinder along the line of the lining rings and get round small feeders. They are suitable for medium-sized animals and provided that we are talking about one or two individuals. Or maybe it will be drinkers for chickens - you decide.

Here you also need to take into account some features, so as not to be upset later. Since food will be poured inside such feeders, it should be especially carefully cleaned inner part from gasoline. If the cylinder has survived multiple refueling and has not been cleaned, then gasoline is collected inside, which has a very strong odor. A strong smell plus oiliness over the entire surface - this must be removed so as not to poison the bird and animals. How to do it yourself: a set of actions helps, including washing in boiling water using various cleaning agents, burning with a blowtorch and cleaning with a drill or angle grinder attachment.

Manual rammer roller

And also from a gas cylinder, and also with your own hands. The skating rink is a rarely used thing, but if you really need it, it is difficult to find it. Compact the asphalt surface if you have to do it yourself and you don’t have to rely on the skating rink; ramming the base under paving slabs, soil compaction - there can be many situations. The main thing is that making a manual ice rink from a gas cylinder with your own hands is even easier than the previous crafts that we mentioned above. A U-shaped pipe with a diameter of about an inch, the ends of which will be attached to the center of the upper and lower parts of the cylinder by means of bearings and a handle of a shape and length convenient for your hands - that's the whole design. Water or sand is used as a filler. Water is lighter, sand is heavier, so the choice depends on the purpose of the rink.

The main thing is safety. Since parts will be welded to the gas cylinder, care should be taken to clean the gasoline to prevent trouble. We will talk about this in more detail at the end of the article.

Other balloon crafts

If you thought that a stove, a feeder and a skating rink are the whole list of what you can do with your own hands from a gas cylinder, then you are mistaken. There is no limit to ingenuity: various containers for storing something, a smokehouse, a barbecue, a feed cutter, an autoclave, a compressor and even a boiler - this is a relatively complete list of crafts. Another thing is that some of these designs are not always justified and it will be easier to purchase (buy) a ready-made unit for safety reasons. If the master knows what he is doing with his own hands and it is so safe for operation, then the question is removed. But if the mind is not enough, then you can either ruin yourself or your relatives. We do not want to offend anyone, but cases are different.

How to disassemble a gas cylinder

We promised above that we will teach you how to disassemble the cylinder safely and we keep our word. First of all, do not think that everything is so simple and safe - if you act incorrectly, you can get burned in the literal and figurative sense of the word. Let's take our youth as an example. This is exactly the period when there is little experience, there was no Internet, but there was a burning desire to use the gas cylinder for other purposes. Logic dictated that even that small fraction of gasoline inside should be wary of, but I didn’t want to get too dirty. Therefore, knocking down the valve with a sledgehammer, we began to fill the cylinder with water, shake it off and drain the liquid. After repeating this five times, we decided that the threat was gone. The grinder began to cut the cylinder along the axis and already 90% completed the work. And only then (!) the remains of gasoline flared up and the master was enveloped in a cloud of flame. It's okay - just burned eyebrows and hair all over the open body - but it's unpleasant.

The instruction will help you disassemble the cylinder (cut) without consequences:

• Even if you are sure that the cylinder is empty, you must open the valve. Bleeding even that small amount of gas, you once again insure yourself.
• The valve must be removed. Here everyone tries by virtue of their capabilities and imagination. Some knock it down with a sledgehammer, others cut it off with a grinder or a hand saw for metal, and still others unscrew it. The last option is the safest, but difficult to do at home. Clamping the cylinder so that it does not scroll under the force of the key is difficult. If cutting the valve at the very base of the cylinder is used, then ONLY with a hand saw! No cutters and angle grinders!
• The hole that formed after removing the valve is small in diameter, but this is enough to pour water inside. Why is it necessary? The water will displace the remaining gas and nothing will flare up when cutting. Here is a little difficulty, or rather, an inconvenience: you need to cut a bottle with water inside and water will surely flow out of the resulting cut. There's nothing you can do about it - this is such a feature that you need to be able to adapt to. For example, the place where you will work with your hands should be such that spilled water does not collect and you do not have to knead the dirt with your feet. Naturally, this operation should take place outdoors, not indoors.
• If an abundance of water cannot be avoided, then you can risk rinsing the cylinder several times, washing off the remaining gasoline. Just note: we specifically wrote the word “risk”, since we cannot give security guarantees. in our case, as you remember, there was almost no gasoline, but a flash of it followed already at the end of the cut.
• Cutting with a grinder is the most fast way. Mark the line with a marker (pencil graphite will quickly fly off the surface from vibration) and start cutting. Since the gas cylinder is round, it is better to put something under it from the sides so that it does not roll during operation.
• Cleaning the inside is necessary even if the balloon structure is not to be used for poultry or animal feed. The smell is strong and persistent, so you need to remove it. To begin with, you can wash it with boiling water using various kinds of cleaning products. This will help partially, so next comes the burning. Blowtorch or campfire - decide for yourself. Both options will help 100% and you just have to complete the cleaning with a metal brush. It is better to use the appropriate nozzle on a drill or grinder to make things go faster.

Instead of a conclusion

As you can see, the question “what can be done from a gas cylinder with your own hands” has many answers. The main thing is your safety, because you are going to work with your own hands, which means you are risking them. Any design that you make from a balloon will last you a long time. Reason: high quality steel, which is now rare. Only we advise you to think over everything thoroughly - is it worth doing the thing with your own hands, if the store version is more reliable. For example, we would not risk working homemade compressor from a cylinder or a boiler - life is more expensive.

Optimizing the cost of heating a country house is a very urgent task for its owner: what to use as fuel, which thermal unit is the best. Very popular home-made stoves from gas cylinders, allowing the use of very cheap, sometimes just junk fuel. In this case, heating costs are minimal.

Making a thermal unit with your own hands from a cylinder

A zealous owner carefully insulates his house, trying to reduce the cost of heating it. In addition, there are a number of objects that need to be heated periodically: workshops, garages, outbuildings. Greenhouses need to be heated regularly or winter gardens.

Therefore, home craftsmen are constantly developing and implementing additional thermal units of various designs. The most popular are products from gas cylinders. The reason for this is a convenient form and almost ideal proportions and characteristics of the material.

Coefficient useful action cylinder stoves reaches 85-90%, which is a very high figure in comparison with home-made stoves of other forms. The rounded shape is ideal for intensive fuel pyrolysis and allows you to arrange holes for the exit of smoke and the supply of oxygen to the combustion zone with least cost.

A simple and efficient gas cylinder stove will last a long time

What is a balloon oven

The well-known "potbelly stove" is a classic representative of thermal units from an old cylinder. She received this name for her extraordinary voracity, consuming a large amount of fuel. But its main advantage is the rapid ignition and heating. This is especially important in extreme situations when, for any reason, the operation of the main heating stops.

In the design of such a furnace, the cylinders can be in both vertical and horizontal positions. Heat transfer occurs through the surface of the furnace and can be significantly increased by welding metal fins onto the surface. In addition, it is possible to utilize the heat of flue gases by passing them through a pipe embedded in a water tank. Water heated in this way is used in the heating circuit or used in the household through an indirect heating boiler.

Pyrolysis furnaces occupy a special place in heating devices from cylinders. Pyrolysis is the thermal decomposition of fuel that occurs with minimal access to oxygen. At a temperature of more than 300 degrees, the fuel in the furnace does not just burn out during the oxidation process, but decomposes into gas fractions, which give higher temperatures when ignited.

Photo gallery: types of furnaces with a cylinder body

What bottles can be used

Not every gas cylinder is suitable for the manufacture of the furnace body. For example, composite cylinders are not recommended. Despite its strength, the composite does not tolerate high temperatures well.

A container of 5 liters cannot serve as a furnace body due to its small size, but containers for liquid fuel are successfully made from it.

You can use cylinders with a volume of 12 and 27 liters. They make excellent thermal units with a capacity of 2–3 kilowatts and 5–7 kilowatts, respectively.

Most often, furnace bodies are made from cylinders with a capacity of 50 liters. Its dimensions - a diameter of 30 centimeters and a height of 85 - are optimal for the installation of a thermal unit. A furnace of this volume is capable of heating a small country house with high quality.

A propane tank with a volume of 50 liters is best suited for a homemade stove body

Oxygen cylinders for stoves are rarely used. The size ratio is not very convenient for the furnace device, and a significant height makes such a unit unstable.

Types of long-burning stoves from a gas cylinder

There are many options for making furnaces from cylinders. Every House master makes changes to them, corresponding to the possibilities and understanding of the process. At the same time, pyrolysis ovens are the most popular. long burning. In such designs, the combustion time of the flue material varies from 12 hours to a day or more, which can significantly reduce fuel consumption.

Furnaces with conical stacking of fuel

A popular type of pyrolysis oven is the conical fuel stacking design. In such a furnace, a pin is installed along the axis of the furnace from the grate. When loading, a wooden or tin cone is put on it with the base up. The furnace is filled from above with sawdust, shavings or wood chips. At the same time, the furnace material must be well compacted so that the bookmark is as dense as possible.

When the fuel is loaded, the cone must be pulled out and the lid closed. Fuel is ignited through a blower with a small amount of wood chips or a dry fuel tablet. As soon as the fuel flares up well, the blower door must be closed, limiting the flow of air into the furnace. Further, the fuel simply smolders, but this is enough to reach the pyrolysis temperature. Smoke is removed through a pipe in the upper part of the body. With this design, "samovar" hot water tanks are also used for the system radiator heating or heating water in an indirect heating boiler. It is convenient to use a gas or oxygen cylinder as a heating container, passing the chimney pipe along the axis of the vessel. A fitting for hot water is welded in the upper part, and a return pipe in the lower part. The circulation occurs naturally without the use of a pump, which makes the heating system energy independent.

The burning time of one bookmark is 12-16 hours.

Sawdust should be compacted as tightly as possible

Liquid fuel pyrolysis ovens

For these thermal units, fuels such as diesel, diesel fuel or used oil are used. The use of other energy carriers is considered exotic due to the high cost.

Consider the option of using used oil as a fuel. To make a simple oven, you need:

1. Install a pipe with a diameter of about 100 millimeters in the upper part of the cylinder.
2. About 30 holes with a diameter of 10 millimeters must be drilled in the walls of the pipe.
3. Place a bowl-shaped container with a diameter of 120–140 mm with sides 25–30 mm high at the bottom of the cylinder.
4. A tube with a diameter of 10 millimeters with oil and a fuel supply regulator is connected to the container through the wall of the cylinder.
5. The removal of combustion products is carried out through the side pipe in the upper part of the body.

Ignition of a cold furnace is carried out in the following order:

1. Open the cock on the fuel tank and pour used oil into the bowl up to about the middle of the walls.
2. On top of the oil you need to pour up to 50 grams of gasoline. Having a lower density, it will remain on the surface.
3. Ignite gasoline. When the temperature rises, the oil boils and begins to emit vapors that also ignite. The flame is drawn into the perforated pipe by the air flow.
4. With a further increase in temperature, pyrolysis of the fuel occurs, and the intensity of combustion increases. Flue gases are removed through the upper chamber along the side pipe. The temperature in the combustion chamber is such that the pipe heats up red-hot, and the furnace body quickly heats up from it.
5. Under these circumstances, it is desirable to partially cool the furnace gases in the chimney using a samovar-type water heating tank.

For all positive qualities such a thermal unit, including the simplicity of design and low cost of fuel, has a significant drawback. In the room where such a furnace operates, the smell of burning petroleum products is constantly present. Therefore, the structure must be taken out of the residential or industrial premises.

An old cylinder and used oil will effectively heat the house

Long-burning solid fuel stoves

Solid fuel appliances use the following types of fuel to generate heat:

• firewood;
• woodworking waste in the form of sawdust, shavings, scraps, chips;
• peat;
• coal.

There are known cases of using used tires for heating after their grinding.

One of the most popular designs of this type is considered to be a home-made stove with the funny name "bubafonya". It can be made with minimal cost labor and materials. The basis for the manufacture is a body made of a gas cylinder with a capacity of 50 liters.

The fuel for such a unit can be technological chips, crushed remains of branches and twigs, sawdust and shavings. The only requirement for it is that the humidity should not exceed 12%, which corresponds to the standards for fuel for wood stoves. The duration of burning of one bookmark is from 14 to 24 hours, depending on the density of its laying. The fuel is ignited after the weight and cover are installed. The ribs on the weight form channels for air, allowing the fuel to burn and decompose into pyrolysis gases. The gases enter the upper chamber, where they burn at a high temperature.

As the fuel burns, the piston moves down.

Slow burning pyrolysis furnace "Bubafonya"

It is impossible to describe or simply list all the designs of furnaces that can be made from cylinders, but it is advisable to consider in detail the design of the "boubafonya". Such a model can be made at home with your own hands.

Safety

Before describing the design of the furnace and the technology of its manufacture, let's pay attention to safety issues. It will be a question of preparation of the cylinder for processing. Despite the dense structure, the inner surface of the metal is dotted with a network of microscopic cracks. During long-term operation of the container for its intended purpose, a considerable amount of gas condensate and its precipitation accumulate inside these defects. Such a substance may be explosive and is in no way beneficial to health. Before you start working with the balloon, you need to fill it with water and let it stand for 2-3 days. The operation is best done away from home. When the liquid is drained, the reasons for such a recommendation will become clear - it has an extremely unpleasant and strong odor.

Tools and materials for the manufacture of the furnace "Bubafonya"

To make such a thermal unit with your own hands, you will need:

Table: required materials and tools

In addition to the above, you will need some tools from the standard locksmith set: a hammer, pliers, etc.

The procedure for the manufacture of the furnace "Bubafonya"

The advantage of this model is that the cylinder body is subject to the least intervention. The manufacturing procedure for the bubafonya furnace is as follows:

The order of laying fuel and ignition of the furnace

The sequence of actions in this case is as follows:

1. Fuel preparation consists in grinding large fragments to the state of technological chips (5x20 mm) and mixing it with sawdust and shavings.
2. Pour fuel into the furnace; at the same time, it is necessary to compact it, achieving the highest mass density.
3. Lightly moisten the surface of the fuel insert with lighter fluid.
4. Install the piston in the furnace body with the pancake down, fully open the damper on the pipe.
5. Close the lid.
6. To ignite the fuel, take a small rag soaked in the ignition fluid and lower it into the pipe. If you just throw a match there, it will go out along the way.

When the fuel is ignited, the furnace heats up. Combustion air will flow through the pipe from top to bottom. When the temperature reaches 300 degrees, the process of fuel decomposition begins. Pyrolysis gases penetrate into the upper compartment and ignite there. From this point on, you can completely close the damper on the pipe.

The combustion process takes place as follows:

1. After closing the damper, air enters the furnace through the slotted gap between the pipe and the edges of the hole in the lid. The combustion of pyrolysis gases creates a sufficient temperature for the decomposition of the following layers of fuel.
2. The ribs on the bottom of the pancake prevent it from sinking onto the fuel layer and blocking the combustion. Through the cavities between them, gases enter the upper chamber.
3. Thus, there is a layer-by-layer consumption of combustible material with the formation of a large amount of heat.

The burning of one bookmark lasts up to a day or more.

Such stoves are no less successful in coping with fuels such as peat or pellets.

Heat recovery occurs by heating the furnace body. However, it cannot be complete. It is also desirable to use the samovar method of taking energy for heating through a radiator heating system.

Calculation of the main parameters of the furnace "Bubafonya"

Effective work furnaces of this design directly depends on the combination of many indicators and their optimal interaction.

Furnace wall thickness

According to the experience of operating long-burning furnaces, 4-5 millimeters are recognized as the optimal wall thickness. This is just such a parameter that a fifty-liter cylinder has. If the wall is thinner, heat transfer is disturbed and the body burns out rather quickly.

Calculation of pancake parameters

The gap between the pancake and the inner wall of the cylinder is determined by the ratio s = 0.5D. That is, with a diameter of 300 mm, this value will be 300 x 0.05 = 15 millimeters. It should be noted that compliance with this parameter is very important. With a larger gap, the fuel near the walls will burn more slowly, as a result of which the pancake may fall into the bookmark and combustion will stop.

As established in practice, the height of the pressure ribs is 40 millimeters.

pancake thickness

This parameter is inversely proportional to the body diameter. That is, the larger the diameter, the thinner the part should be. There are tables of such dependence on the Internet, for our case this parameter is 6–10 millimeters. Exact data and calculation methods are not given, but it is quite enough to adhere to the published recommendations.

Chimney section size

The minimum allowable cross section of the chimney is determined by the amount of energy released per hour of operation of the furnace, which is determined by the ratio S = 1.75E (kW / h). Here E \u003d mq, where m is the mass of fuel in the load, q is the specific energy of the fuel burning for an hour, a tabular value. Necessary information shown in the table.

Table: data for calculating the section of the chimney

Having made the necessary calculations, we obtain the minimum required diameter of the chimney for the Bubafonya stove is 150 millimeters.

Air intake pipe size

Preparing for assembly, choosing an installation site

Before starting work on assembling the furnace, it is necessary to prepare the place of its installation. After pouring the foundation, it will take time for the concrete to harden. During this period, you can slowly make the oven itself. The foundation can be used no earlier than 7 days after pouring. over concrete base you need to lay out a platform of refractory bricks.

A good foundation is essential for safe work ovens

When choosing a place to install the furnace, you need to consider the following circumstances:

• the distance to the nearest walls of combustible material must be more than one meter; if there is no such place, the walls must be additionally protected from heating with an asbestos sheet 8–10 millimeters thick; on top of it, install a sheet of galvanized metal with a thickness of 0.5–0.7 mm;
• the chimney in the vertical part must not fall on the supporting beam;
• if an external chimney is used with an outlet through the wall, the length of the horizontal part should not be more than one meter; otherwise, you need to make a chimney with a slope of 45 degrees.

The preparation of parts and assembly of the furnace is best done indoors, for example, in a garage. This will save neighbors from unnecessary noise when working with a grinder and from the sparkling of an electric arc. The room needs to be furnished exhaust ventilation. If welding is carried out in the open air, the place of work must be protected with protective screens.

Furnace modernization

Improving the parameters of the furnace is associated with an increase in its heat transfer. For this, additional heat exchange surfaces on the furnace body are used. Such parts can be made from various metal profiles, including strips, angles, profile pipes. The choice of material depends on what is available from the leftovers.

Additional heat exchangers from metal profile increase the efficiency of the device

Additional heating surfaces can be installed not only on the outer surface, but also inside the furnace, which allows you to intensively heat the air in the room. The negative result of such a decision will be the burnout of oxygen at high temperatures.

Features of the operation of the pyrolysis furnace

The main difference between pyrolysis furnaces is the ability to use a wide variety of fuels. In solid fuel stoves, it is allowed to burn not only traditional combustible substances, but also rubber, plastic and other materials that are categorically not recommended for heating conventional stoves.

This feature is associated with the complete decomposition of the fuel and the secondary combustion of the resulting gases in a separate chamber. After that, only carbon dioxide and water vapor remain in the smoke emissions. There are no harmful emissions into the atmosphere during pyrolysis.

But when using such fuel at the ignition stage, a persistent smell of burnt rubber remains in the room. Therefore, such thermal units must be installed outside residential premises.

Maintenance of pyrolysis ovens

Pyrolysis ovens require much less attention compared to conventional devices. This is due to the fact that there are practically no solid particles that form soot in the flue gases. The presence of water vapor in the exhaust predetermines the formation of condensate on the walls of the chimney. Therefore, it is necessary to install a condensate collector with a drain cock, which must be used regularly as it accumulates.

This statement is true for perfectly balanced furnaces, where complete decomposition of the fuel occurs. But a breakthrough of conventional furnace gases cannot be ruled out, therefore regular inspection of the inner surface of the chimney is necessary. If necessary, it must be cleaned. Inspection is carried out at least twice a year.

On long-burning furnaces, an insulated pipe made of of stainless steel.

Waste oil stoves should be cleaned regularly as carbon deposits and slag deposits form in the fuel bowl. In the first combustion chamber of the fuel, normal combustion occurs with the release of solid particles. The design of the furnace allows you to visually monitor the condition of this unit.

With the independent manufacture of a furnace for heating, there are no trifles. Each circumstance must be carefully weighed and thought out. Otherwise, all efforts will be in vain. I wish you success!

Do-it-yourself gas cylinder stove: drawings, types, creation technology

A gas cylinder stove can be placed where heating cannot be arranged in another way: in a garage, country house, change house.

If you have the desire and time, you can do all the work yourself.

This article will help you independently convert a gas cylinder into a heating or heating and cooking stove.

Here you will find drawings and instructional videos with which you can make a waste oil, coal or wood stove.

Varieties of furnaces from a gas cylinder

A do-it-yourself gas cylinder stove is considered the easiest option for making a potbelly stove or heating apparatus for working out.

The cylinder is easily transformed into a stove body. To work, you need a grinder and an inverter or any other welding machine.

The shape of the cylinder allows you to make a furnace with a spherical furnace. Firewood in a stove of this form burns slowly - as a result, a kind of heat generator is obtained, capable of heating the room for hours on one tab of firewood.

A homemade stove from a long-burning gas cylinder can be used in different ways:

• as heating and cooking in residential premises;
• as heating for heating one or two rooms;
• as a cooking for use in the summer in the country;
• as an emergency portable option for use in case of failures in the main heating system.

Advantages of gas cylinder stoves:

• you can get a long-burning apparatus at practically no cost, since the system is assembled from standard inexpensive elements;
• all work can be done independently, no need to look for specialists;
• suitable for heating baths;
• video materials are available with positive experience in creating furnaces of various designs;
• simple operation.

The disadvantages include the moment that the work should be done according to reliable drawings - otherwise the design will not have the required efficiency.

For work, you will need to choose a suitable cylinder. You should opt for an all-metal cylinder with a volume of 12 or 27 liters.

However, for a full-fledged heater, a gas cylinder with a volume of 50 liters and a diameter of 30 centimeters is chosen. Any fuel, including coal, can be burned in a tank of this volume.

Even before the start of work, it is necessary to decide on what type of fuel the furnace will operate. If you need a long-burning furnace, then it is better to provide for the possibility of loading coal into it.

A long-burning stove can be made small, only on wood - for this, it provides for the possibility of regulating draft.

The most difficult thing is to manufacture liquid fuel heating devices: waste oil, diesel fuel. On the other hand, a waste oil furnace allows you to reduce heating costs, since oil is inexpensive.

It is better for a beginner to start with more simple designs, for example, try to convert a gas cylinder into an ordinary potbelly stove.

Solid fuel stove

How can you make a stove from a gas cylinder? The first question that arises even before starting work is: how best to position the tank - horizontally or vertically?

If you want to use the stove for cooking, you will have to place the cylinders horizontally.

In the vertical version, grates will definitely have to be installed inside the cylinder; in the horizontal version, this is done as desired.

But in a horizontal structure, it will be necessary to weld a tray for collecting ash, and in a vertical one, when installing the grate to a sufficient height, the ash pan can be omitted.

The potbelly stove will require cast doors for the blower and fuel chamber.

Home craftsmen make them themselves from a piece of metal cut from a cylinder when making a hole for the combustion chamber.

In this case, you only need to purchase hinges and a latch handle. For a purchased door, you will have to weld a frame welded from the corners onto the cylinder around the perimeter of the holes, and bolt the fittings to it already.

Before you start cutting or welding metal, you need to empty the container from the gas. The cylinder is filled to the top with water, then it is drained, and only after that they begin to work.

Stages of manufacturing a horizontal potbelly stove:

1. cut off the top of the container with a grinder;
2. install a grate made of bent reinforcement inside the cylinder;
3. fittings are welded to the tank;
4. a circle is cut out of steel 4 mm thick, equal to the outer diameter of the cylinder;
5. holes-rectangles are cut in a circle - the first under the firebox, the second under the blower;
6. weld a steel circle;
7. fix doors;
8. paste over the doors along the contour with asbestos cement;
9. they begin to re-equip the back of the furnace - they cut out a hole for the chimney equal to the diameter of the pipe;
10. a chimney is welded from a thick-walled pipe.

When the cylinder is located vertically, a design will be obtained that takes up a minimum of space.

Such a cylinder stove is suitable for a bathhouse, a small living space, it can be put in a garage.

Stages of manufacturing a vertical potbelly stove:

1. cut off the top of the cylinder with a grinder;
2. a large hole is cut out on the front of the future furnace for the furnace, below - under the blower, through which the structure will be cleaned of ash;
3. inside the cylinder, a grate of reinforcing bars is lowered and welded to the walls;
4. a border is welded to the holes under the doors and pasted over with an asbestos-cement cord;
5. the top is welded - it was cut off only in order to put a grate;
6. a chimney opening is made from above or from the side.

Bubafonya oven and rocket oven

An ordinary potbelly stove has a significant drawback - low efficiency. A huge amount of heat escapes through the chimney.

In addition, as soon as the fire goes out, the structure immediately cools down. Pyrolysis furnaces, that is, devices capable of maintaining long-term combustion, are deprived of these shortcomings.

The simplest pyrolysis oven can be made from a gas cylinder. Masters call such devices bubaphones.

The bubafonya stove from a gas cylinder was invented by a craftsman from Russia. This happened recently, but bubafonya has already become very popular.

How does the bubafonya type apparatus, converted from a gas cylinder, work? A movable piston is installed inside the container, dividing the balloon into two parts.

Fuel (firewood) burns under the piston, and above it - gases released from firewood as a result of pyrolysis.

This principle of operation leads to the burning of firewood in the "reverse order" - from top to bottom.

Reverse combustion is slower than usual, in which oxygen is supplied to the fuel chamber from below, through the blower holes.

In a bubafon, air is supplied to the furnace by a piston axle, which is a hollow tube. Oxygen enters the pyrolysis chamber through openings cut at the end of the gas cylinder.

The division of the furnace into two compartments allows the wood, even with a lack of oxygen, to burn through to the end without turning into coal.

The system is so efficient that a bubafon from a gas cylinder on one tab of firewood works for 4-6 hours.

There are reliable reviews that a bubafonya from a 200-liter barrel works on one tab for a whole day.

Bubafonya can be used for water heating. To do this, the gas cylinder is enclosed in a water jacket using another metal case, and a water pump is connected to the system.

The rocket stove was developed as a design for survival in extreme conditions. It has high efficiency and maximum safety.

At the same time, a home-made rocket stove is so simple that a non-professional can make it. In rocket furnaces, the principle of pyrolysis is used, that is, fuel decomposes into volatile substances under conditions of oxygen deficiency.

The simplest pyrolysis furnace can be made from any cylindrical metal container, for example, a barrel or a gas cylinder.

Rocket stoves can be equipped with benches. Such structures are still used in China and Korea for heating peasant houses.

Structurally, a rocket stove from a gas cylinder consists of a blower, a fuel chamber with a blank cover, a channel for oxygen supply to the pyrolysis chamber, a flame tube in which gases are burned, and a chimney.

Liquid fuel stove

In individual farms, it is sometimes possible to use used engine oil. In this case, heating costs are drastically reduced.

To burn oil, you need to assemble a special furnace that runs on liquid fuel. A mining heater and a simple wood-burning stove work on a different principle.

At first glance, a working oven is no more complicated than a pan, but complex chemical and thermal processes take place in it.

The furnace for mining from a gas cylinder consists of the following parts:

• oil containers;
• dampers regulating combustion;
• holes for filling oil;
• chimney.

For the manufacture of a furnace from a gas cylinder, tanks with a volume of 50 liters are used.

The balloon is sawn in a ratio of 2:1. The smaller part will go to the manufacture of the tank, the larger one will become the afterburner.

The principle of operation of such a furnace system is as follows:

1. oil is poured into the fuel bunker and set on fire;
2. air is fed into the chamber through an air throttle and thus greatly limit the intensity of combustion;
3. as a result, the fuel does not burn, but evaporates, that is, the pyrolysis process begins;
4. oil "steam" rises to the upper chamber and burns completely there.

In other words, the fuel is used twice - first the oil burns, and then its vapors burn out. As a result, no waste remains, and the efficiency of such a furnace is as high as 80%.

Waste oil is a heavy, heavily polluted and poorly burning mass complex composition. Two-stage combustion allows you to fully use the entire resource of this fuel. The structure is vertical.

On top of it, you can install a lattice-stand for placing buckets, pans and other utensils.

Drawings that must be strictly adhered to and training videos will help to make a furnace for testing from a cylinder.

The disadvantage of liquid fuel stoves can be attributed to increased safety requirements. Fuel reserves have to be stored away from the boiler room.

A waste oil-powered structure cannot be used as a sauna stove, but it is useful for heating workshops, change houses and residential premises.

In the latter case, it is better for her to build a separate boiler room in the form of an extension to the house.

So, now you know how to make any oven from a metal gas cylinder with your own hands.

Having the necessary drawings, a grinder and an inverter, you can easily make a mobile and efficient heating device that will help out in winter time when other types of heating are turned off or unavailable.

What can be done from a gas cylinder with your own hands

As a preface

Many of us often have gas cylinders left in our homes. They are made of fairly high-quality metal, which is sometimes just a pity to throw away. In order to get started, you will need a similar capacity of 50 liters. It often remains from propane.

A little about security measures

You may not even suspect it, but there will be gas residues inside. Of course, you can’t start working with them, you need to get rid of them. To do this, simply open the container and leave it for a few hours. Just make sure there is no fire nearby. Also, after all this, rinse the container with water. It will completely rid the balloon of gas residues. You can also use chlorine or lime for cleaning. The truth may remain after this bad smell. But it's easy to remove. It is enough just to hold the product over the fire for a while. Wait for the paint to burn off.

Work process

From the resulting cylinder, it will be possible to make a portable compressor station without any problems. Surely you have a large number of wheels on the farm. They need to be pumped up from time to time. So such a homemade invention will be most welcome. Small wheels will make such a station as mobile as possible, you do not have to carry heavy tires with you.

In order to get started, you must first find a gearbox, the maximum pressure of which will be 2 atmospheres. With it, even children will pump up the wheels without any problems.

Next, you can easily build a stove. It will do an excellent job of heating the workshop. To create it, you need only one burner, which can heat up to 140 degrees and a small chimney. By the way, with such a device it is possible to easily dry nuts and do many more manipulations. Look at the pictures below to see what it looks like.

Of the interesting, it should be noted the skating rink for the garden. It can also be used as a track leveler. To do this, it is enough to simply prepare a special iron base, which you can easily hold on to. You can make such a skating rink in just an hour, or even less. It all depends on how quickly you find the iron handle.

Lovers of outdoor recreation can also be satisfied. In particular, you can make a quality barbecue. To do this, simply cut off the top. By the way, it is possible to make a smokehouse without any problems by combining several cylinders at once. Look at the photo below. Looks attractive enough.

By the way, if you have any parts from the cylinder, then in no case throw them away. From the half it is possible to make a stand for the burner. Just need to attach a few small legs. You can also use part of the sidewall. It should be used as a protection for the sharpener.

As you can see, there are a lot of options. If you have no desire to do something complicated, then you can, for example, make an ordinary urn out of a balloon and decorate it. In general, it is enough just to show your imagination. Do you have piglets? Then just make a feed trough for them. This is a great opportunity to save money.

Do-it-yourself potbelly stove from a gas cylinder: instructions for making

Many private households have old cylinder from under liquefied gas. Many useful things can be made from this object, for example, a simple heating device.

If there is a desire and a welding machine, then a potbelly stove from a gas cylinder with your own hands can be made without any problems. Of course, some additional materials will be needed.

How it works

Potbelly stove - a primitive version of a metal wood-burning stove. Such a device works extremely simply: firewood is laid in the furnace, they burn out, the furnace body heats up and gives off heat to the surrounding air. Smoke gases are removed through the chimney, and the ash is poured through the grate into the ash pan, which should be cleaned periodically.

One of the main advantages of a potbelly stove is the simplicity of design. There are no strict dimensions here, the main thing is that the body can withstand heat, and the chimney works properly. Experienced Master will make such a stove in just a couple of hours. And you can burn almost any dry tree in it: both logs and sawdust.

They heat a potbelly stove with other combustible materials: diesel fuel, coal, peat, household waste, etc. If desired, on such a stove you can cook quite successfully. This moment should be considered even before the start of the manufacture of the structure in order to make a flat hob.

The potbelly stove is a combustion chamber made of thick metal with a loading door, a chimney, a grate and a blower. You can use an old gas cylinder as a housing

But one should also take into account the disadvantages of such a heating solution. For starters, this is a high risk of burns and fires. For a potbelly stove, you need to choose a special place, finished fire-resistant materials. It is desirable that she stand to the side, where no one accidentally touches the body and does not burn herself.

If desired, the upper part of the vertical potbelly stove from an old gas cylinder can be turned into a hob of modest size

Such a metal structure weighs a lot, so there is no question of any mobility of the device. Move potbelly stove for heating different rooms it will be difficult. Such stoves are usually used to heat utility rooms in which there is no electricity or where it is supplied intermittently: a garage, a barn, a workshop, etc.

From two gas cylinders connected perpendicularly, you can make an improved version of the potbelly stove, which allows you to save more heat and get high returns when burning fuel

Another problem is the low efficiency, since part of the thermal energy during the combustion of wood literally flies into the chimney. There are various ways to keep warm and modify the potbelly stove a little to make it work more efficiently. Finally, you need to take care of good ventilation of the room in which the potbelly stove is installed, since such a device burns a large amount of oxygen during operation.

So, a potbelly stove consists of a metal case, the role of which is usually “invited” to an old gas cylinder. In the case it is necessary to make two doors: large and small. The first serves to load fuel, the second is needed as a blower through which air enters the combustion chamber to ensure the combustion process and traction.

A drawing of a potbelly stove from a gas cylinder allows you to make a device with specific parameters and calculated power, but such accuracy is not necessary

Below, at some distance from the bottom of the structure, a grate should be welded. It can be made from thick wire or just take a sheet of thick metal and cut long slots in it. The distance between the bars of the grate should be such that the furnace material does not spill down into the ash pan. If the potbelly stove will be heated only with firewood, the grate gaps are made large, but when wood chips are supposed to be used, the grate should be made more frequent.

A curved metal chimney mounted on a potbelly stove from a gas cylinder allows you to keep more heat in the room and increase the efficiency of the design

The ash box can be welded from sheet metal or you can take a ready-made metal container of a suitable size and resistant to strong heat. Some people prefer to do without an ash pan at all, they simply scoop out the ash from the lower section as needed, although this is not very convenient. The chimney is usually brought up to provide the necessary draft.

Potbelly stove from a cylinder can be different: the container can be placed horizontally or vertically. You need to choose the right size case, and then use it correctly. You will need sheet metal made of steel that is resistant to prolonged heating, thick wire for the grate, a corner for legs, etc. In the manufacturing process, a number of nuances should be taken into account to make the stove convenient and efficient.

How to choose and prepare a balloon

Gas cylinders are very different. For a potbelly stove, a container for liquefied gas of 50 or 40 liters is best suited. If you need a small oven, you can take a cylinder with a volume of 12 or 27 liters. But it will be a device for heating small utility rooms. Similar containers of five liters are practically useless. Such a small potbelly stove will heat up quickly, but will soon cool down, so the heating effect from it will be very insignificant.

An interesting option for a homemade potbelly stove is a freon container. Such a cylinder has thick walls and an elongated body. The container must be cut so that the length of the body is approximately 70 cm. Thick walls, of course, make the structure heavier, but retain heat better. The potbelly stove will warm up for a long time, but it will also heat up longer.

Before starting work, it is necessary to properly prepare the gas cylinder: bleed the remaining gas from it, drain the condensate and fill the container with water, which can then be poured out

When the cylinder is selected, you need to prepare the welding machine and remember the safety rules. Even in a very old cylinder there will always be some residue of combustible gas. If you immediately start cutting it with welding, a life-threatening explosion is almost guaranteed.

To begin with, it is recommended to open the cylinder and bleed off the remaining gas. Of course, this should be done outdoors, not indoors. Then you need to drain the remaining liquid from the cylinder, condensed inside. This substance usually has a pungent and unpleasant smell, so it is best to prepare a small container with a lid for it in advance so that it can be neatly packaged and discarded immediately.

There are no particularly strict requirements in terms of parameters for the design of the potbelly stove. The larger the combustion chamber, the more spacious the room will be able to heat the unit

If condensate is accidentally spilled on the floor in a room, the peculiar aroma may remain very long time. After all these operations, the cylinder is still not ready for contact with the welding machine, because residual gas vapors remain inside. It is necessary to fill the cylinder with water to the very top in order to completely expel all the gas from it. After that, the water is drained, now the balloon can be cut without problems.

Manufacture and filling of the case

Next, you need to choose the type of potbelly stove from the cylinder, whether the cylindrical body will be located horizontally or vertically. All other operations are carried out with this orientation in mind. If a horizontal position is selected, then one of the ends of the cylinder will serve as the rear wall, and on the other, you need to install a loading door and a blower.

If it is planned to manufacture a vertical potbelly stove from a gas cylinder, you will need to make two holes: for loading fuel and for blowing with an ash pan

For the grate, you can use thick reinforcing wire. In order not to cook a lattice from it, you can bend it with a frequent zigzag, “snake”. This design is welded to the inner walls of the metal case. The front wall is made of sheet metal in the following way:

1. The metal must be attached to the front of the stove in order to mark up.
2. According to the markup, a round part should be cut out.
3. Apply one more marking on it: for a rectangular door and a blower.
4. Cut holes according to the markup.
5. Make doors.
6. Weld hinges, locks to the front wall and hang the doors.
7. Weld the wall with doors to the body.

Both doors along the contour should be sealed with asbestos-cement cord so that they fit well to the body. The back wall in such a potbelly stove usually does not need to be done, its role is played by the bottom of the cylinder. In the upper part of the body, close to the back wall, you need to make a hole for the chimney.

The pipe must be taken from thick metal, since the lower part of the chimney will be in contact with heated flue gases. thin metal in this place will quickly burn out. Now, strong legs made of reinforcement, pieces of metal or pieces of a metal corner are welded to the bottom of the stove. They must withstand both the weight of the structure itself and the fuel that will be loaded into it.

Approximately the same technology is used to make a vertical potbelly stove from a cylinder. The bottom of the cylinder will become the lower part of the structure, at the top you need to make a cylindrical “roof” with a hole for the chimney. Usually the top of the balloon is cut off. At the end of the installation, it will be possible to weld it back. Doors - for loading and blowing - are made in front of the cylinder body.

Such a potbelly stove will occupy less space than the horizontal version, and also it will be higher. If it is supposed not only to heat the room, but also to cook food, then it will be necessary to adjust the height of the stove taking this moment into account and ensure a flat hob. But usually the diameter of the cylinder is not large enough to provide a full-fledged opportunity for cooking. Although boiling the kettle is a doable task.

This drawing allows you to get an idea of ​​​​the device of a horizontal version of a potbelly stove from a cylinder, to the bottom of which an ash box is attached

The grate can be made in the same way as described above: from reinforcement bent by a snake along the diameter of the pipe. It is welded between the holes for loading and blowing. Some are trying to reduce welding work, leaving the top of the balloon virtually untouched. But then all other work will be more difficult to perform.

In a horizontal potbelly stove, you can not weld a grate, but turn a part of the body into it by drilling holes of a suitable diameter and attaching an ash box from below

For example, the grate will not have to be inserted from above, but pushed into the furnace door and somehow held in the correct position. Now you need to make doors with hinges and locks and weld them to the potbelly stove body, having previously sealed it with an asbestos-cement cord. It remains to install the chimney at the top, and weld the legs at the bottom.

Doors, grate, ash pan

Doors for potbelly stoves can be made from those parts of the body that remain after cutting holes. Hinges and latches are welded to them. These are easy elements. Loops can even be made from the links of a thick chain. The second, more expensive, option is to buy prefabricated cast metal structures.

To install a finished cast door on a home-made potbelly stove, you should weld a frame from a metal corner to the loading hole

You can choose two separate doors: a large one for the loading opening and a narrow one for the blower. But there are also kits in which such doors are combined into a single design. Holes for such doors must be cut exactly to size. After that, a frame from the corner must be welded to the edges of the openings.

A few links of a thick chain, similar to a bicycle, can be used as hinges for a homemade potbelly stove door made from a balloon

The frame of cast doors is attached to the resulting frame with bolts. It is recommended to pre-weld a small side so that there are no gaps, and the oven is hermetically sealed. In small potbelly stoves, if desired, you can do without a grate at all.

On the left is an inverted body of a horizontal potbelly stove with an ash pan welded to it, and on the right is a general view. The ash pan is pulled out to regulate the flow of oxygen; there is no need to do a blower in such a model

It is difficult to find a place for it if they make a small or low stove, for example, a horizontal version. In such a device, a blower is not made; air is provided with the help of a loading door, which is simply opened slightly. It is easy to make grates from reinforcement, but they are not particularly reliable.

Over time, the reinforcement burns out, it has to be replaced. Alternative option it can become a piece of sheet metal in which slots or round holes are cut. To collect the ashes, you can use a special box - an ash pan. In the horizontal version of the potbelly stove from the cylinder, the grate can be installed in the lower part, complete with an ash pan, since the lower part of the body will have to be cut off to facilitate installation.

How to increase efficiency

To make the work of the potbelly stove more efficient, there are several simple ways. To begin with, the chimney should be insulated to retain some of the heat that escapes with flue gases. Can be used various methods to increase the area of ​​contact of the heated metal with the surrounding air.

Some experts recommend making the chimney not strictly vertical, but curved. This will increase the path of combustion waste and allow some of its heat to return to the room. But it should be remembered that the complicated design of the chimney can adversely affect traction, so you should not get carried away with excessive bends.

Sometimes metal wings are welded to the body of the potbelly stove, for example, made from a corner or any suitable strips of metal. If the size of the stove allows, you can weld a horizontal sheet of metal on top and make an additional hole in it not for the chimney, but for a pot or kettle. The hole is closed with a special composite cover of several concentric circles. By removing or adding circles, you can adjust the degree of heating.

Another option for modernizing a potbelly stove is a brick case. Masonry is performed around the stove, while leaving a small gap between the metal case and the brick. The brick will absorb some of the heat energy and then gradually release it to the surrounding air.

If you wrap the chimney with a metal mesh and put stones in the resulting gap, you can increase the heating efficiency. Even after the firewood burns out, the stones will give off heat for some time.

An alternative version of such an upgrade is a metal mesh around the chimney, into which pieces of brick or stone are placed. This is a popular solution for sauna stoves, a variation of the heater. But it should be remembered that only river “pebbles” of a uniform color and without inclusions are suitable for this. If the stone is layered different type, it can break under the influence of high temperatures.

If you need a solid-sized oven, the master has two gas cylinders at his disposal, you can combine them into one design. One of them is installed horizontally, and the second is placed vertically as a pipe for a chimney. The heating area increases, such a potbelly stove will work more efficiently.

Metal pipes built into the body of the potbelly stove in combination with a fan allow you to increase the heating rate of the room, but to achieve this effect, you will need electricity

Finally, you can insert pipes inside the upper part of the body through which air will circulate. If you put a fan at the end of these pipes, the air will move faster. Such an equivalent of a fan heater will allow you to warm up the entire room in a few minutes and distribute heat energy more efficiently.

Conclusions and useful video on the topic

A potbelly stove is a small home-made metal stove that became widespread in the first half of the 20th century. Later, with the advent of centralized heating, its popularity fell. The second wave of its mass use fell on the years of the Great Patriotic War, and the third - in the 90s of the same century, for heating summer cottages. Today, potbelly stoves are more often used in garages or utility rooms. In their pure form, without alterations, they are uneconomical: they “eat” fuel like bourgeois, and you stop “feeding” them, they quickly cool down. The easiest option to manufacture is a potbelly stove from a gas cylinder. The case is already ready, you just need to cut holes for laying fuel and an ash pan, and attach doors to them, weld legs and a chimney (diameter 150 mm and no less).

The cylinder in such a stove can be placed vertically or horizontally. It warms up quickly, but it also cools down immediately after the fuel stops burning. However, in order to quickly remove the garage or cottage from sub-zero temperature or to heat in the autumn / spring bad weather - great option.

What bottle to take for the stove?

It is clear that a gas cylinder will go for the hull. But they are different sizes. The smallest ones of 5 liters should not be used for the manufacture of furnaces: the volumes are too small and it cannot heat anything. There are also cylinders for 12 and 27 liters. They will make a low-power unit for a very small room: more than 3 and 7 kilowatts of heat cannot be obtained from them. Basically, it could be hiking option, but the weight will be solid.

The best option for a stationary potbelly stove in the garage or in the country is a 50 liter gas cylinder. Height 850 mm, diameter - 300 mm. The volume and wall thickness are large enough to burn any fuel. At the same time, it is not very heavy, you can work with it alone. A potbelly stove made from a 50 liter propane tank is the best option.

Industrial 40-liter gas tanks have about the same volume, the diameter is smaller - 250 mm, the height is greater, and the walls are thicker. A stove from a freon cylinder, with the same power that can be obtained from it, will be more difficult to make: the mass is large, and it is long. By shortening the height to about 700 mm, you can make a small thick-walled potbelly stove, which will warm up a little longer, but it will also be a little better to “keep” the heat.

Important! When working with gas cylinders, observe safety precautions!

How to safely disassemble a gas cylinder: see safety precautions in this video.

From what and how to make doors

Doors for potbelly stoves can be bought cast. It will take a small height on the blower and bigger size- for laying fuel. There are ready-made blocks - a flow door with a blower in one design. In this case, a frame welded to size from the corners is welded into the hole cut to size, casting is already bolted to it. In order not to blow out of the slots, a small rim is welded along the perimeter of the cutout under the door - a 1-2 cm strip of metal.

You can not buy doors, but use a cut-out piece of the balloon wall. Then you will need some loops or replacement parts. It is clear with loops: mark places, weld. There is such an interesting version of homemade loops: several links of a thick chain.

A latch will need to be welded to such a door.

With grates or without?

In the very simple option no grates are provided. If the balloon is small, or stands horizontally, then it is problematic to select a part inside. In this case, the design of a potbelly stove from a cylinder is quite simple: a body placed on legs, one door, a pipe for connecting a chimney is welded in the upper part. All. The whole oven.

The photo above is an example of such simple ovens. In them, to improve heat transfer, metal strips are welded to the body from the outside. In the upper part, in addition to the smoke pipe, there is one more outlet - a cover is installed on it, and this outlet is used as a stove for cooking, heating tea.

If you still want to make grates in a potbelly stove from a horizontally installed cylinder, you will have to weld the ash tray from below. Below is a drawing and a photo practical implementation.

IN vertical options potbelly stoves from a cylinder most often install grates. In this case, the place is easier to allocate. Usually bars of thick reinforcement are welded inside: it is difficult to find a cast-iron grate of a suitable size. But this option is bad because the fittings quickly burn out, and the repair is difficult: remove the old fittings, weld a new one. You can weld pieces of a thick corner or reinforcement inside (as in the photo), separately weld the grate from the reinforcement and lay them on the corners.

This video talks about how to make a stove from a gas cylinder with your own hands - the grate is made of fittings.

We improve heat dissipation

The most a big problem bourgeoisie: inefficient heat consumption. Most of it literally flies into the flue gas pipe. This disadvantage is effectively combated in top-burning furnaces with afterburning of flue gases, similar to the Bubafonya furnace (also, by the way, can be made from a gas cylinder) and Slobozhanka.

A variant of a potbelly stove made of propane cylinders with secondary afterburning - the efficiency is higher than that of "ordinary" models.

Another way to improve heat dissipation is to make the chimney longer, thereby increasing the amount of heat that will remain in the room. When designing such a broken chimney, it is better to avoid horizontal sections, and even more so sections with a negative slope.

This gas-fired stove is wood-fired. Increased heat transfer by making a long broken chimney

Another option to use the heat of flue gases is to weld a vertical cylinder-flue pipe to a horizontally located cylinder-case. Due to the larger area, the heat transfer will be higher. It will only be necessary to create good traction so that the smoke does not go into the room.

You can do it the way they do it sauna ovens: around metal pipe put a net in which to pour stones. They will take heat from the pipe, and then give it to the room. But. First, until the stones heat up, the air will warm up slowly. Secondly, not all stones are suitable, but only round ones, which are along the rivers. Moreover, uniformly colored without inclusions. Others cannot be covered: they can explode from high temperatures no worse than a fragmentation projectile, or emit radon, which is very harmful in significant concentrations.

But such a solution also has advantages: firstly, the pipe will not burn. Stones emit even heat. Secondly, after the stove goes out, they will maintain the temperature in the room.

Often you need to quickly heat the room. To do this, you can use a conventional fan that will blow around the body and / or pipe of the furnace. But the same idea can be carried out with a stationary version: weld through pipes into the potbelly stove cylinder in the upper part. On the one hand, attach a fan to them (heat-resistant, preferably with several speeds, so that it is possible to regulate the temperature).

Another option that allows you to achieve active air movement along the walls of the case and not use a fan at the same time: make a casing around the case at a distance of 2-3 cm, but not solid, but with holes at the bottom and top. Buleryan stoves or metal stoves for saunas work according to this principle.

One of the options for such a casing around a horizontally located cylinder is visible in the photo below. Through the gaps that are at the bottom, sucked cold air located near the floor. Passing along the red-hot body, it heats up, and exits from above.

The principle is not new, but it is no less effective. What the finished stove looks like with such a casing, see the photo below.

Here is another implemented casing, around a potbelly stove from a horizontally located cylinder. Pay attention to the non-standard fastening of the door.

A home-made boiler from a gas cylinder for water heating can be made according to the same principle: weld a water jacket around the cylinder, and connect it to radiators. Just do not forget that the system must have an expansion tank with a volume of 10% of the total displacement.

Brazier from a gas cylinder: varieties and manufacturing instructions

Every lover of sitting with friends or with family in the evening at a barbecue in the country needs a barbecue. But those braziers that are often slipped to us in the store are not suitable either in size, or in quality, or in the thickness of the metal.

And therefore, the best way out will be to make a brazier with your own hands, and the most convenient blank for this will be a gas cylinder, which in itself is already a brazier, you just have to cut it along the grinder.

The gas cylinder has very thick walls, because it has to withstand very great pressure, and therefore any product from it will be reliable and will last a long time. Its diameter, that is, the width of the future brazier, just fits the average skewer, and the height can always be made in accordance with your height, so that it is convenient to roast meat. About some varieties of barbecues from gas cylinders, and in particular, about the technology of their manufacture, we will talk in this material.

Preparation

Whatever design we choose for ourselves, in any case, everything will begin with the fact that the cylinder needs to be rid of gas residues and cut in accordance with the drawings.

So, we take an ordinary 50 liter propane gas cylinder, and we look at the object no longer from the position of its intended use, but with an assessment of what and how it can turn out in the process of interfering with its structure grinders, drills, welding machine and other tools. And, of course, the first priority is to get rid of the remaining gas in the cylinder.

Do not trust people who say that the tank is empty. The concentration of gas, even in an “empty” cylinder, is probably enough to break this metal shell into pieces upon contact with sparks, causing a lot of injuries to the unlucky creator of barbecues along the way. And therefore, nevertheless, we unscrew the crane completely. On an old cylinder, the fitting may refuse to scroll straight, and therefore you will have to rip off the “sticky” metal with improvised means. The very first thing you can do is try to rip it off at the same time by leaning on the open end wrench and, in addition, tapping on the free space of its handle with a hammer.

If this does not help, you should resort to the help of a now adjustable water wrench, on the longer, flattened handles of which you can put a long metal pipe as a lever.

No thread can withstand such an effort, the main thing is to fix the cylinder so that it does not turn with the key, using a stop corner.

Also, in order for unscrewing to go more smoothly, you can moisten the place where the thread of the tap comes into contact with the cylinder with “Vedeshka”, after waiting for two hours and letting the liquid act.

Then the container must be filled with water so that it pushes all the combustible gases out of the cylinder without residue. Having done such a manipulation, you can be 100% sure that in the process of cutting you will not fly away on your potential barbecue to the moon.

Once the container is full, it is not recommended to immediately drain the water. Instead, you should screw the valve into place and proceed to mark the body.

This is done in the following way. On one side of the cylinder there is already a factory longitudinal seam, which in this case will serve as a kind of beacon for us. Having measured the full length of the circle, we divide it in half and put marks on half of it, that is, on the side opposite to the lighthouse. After we measure another 8 cm from it towards the lighthouse, this will be the mark by which the container lid should be marked. We add 8 cm so that the container is deeper, can accommodate more coals, and the meat does not burn at a low height.

After that, you can take the grinder and cut out that part of the cylinder body, which from now on will turn into a kind of barbecue cover. At the same time, it is worth paying attention that you need to cut not along the seam itself, but next to the existing seam, otherwise you can damage the inner steel ring that fastens the structure. The edge of the ring will be needed to hold the lid to the canopy, that is, so that it does not fall into the brazier.

The photo below shows how the master, without understanding the situation, incorrectly cut the frame. Looking closely, you can distinguish a ring on the left inside the balloon. If he cut with a grinder near the seam, the edge of the ring would remain sticking out, thereby acting as a “brake” for the lid. But in any case, this is easy to fix by simply welding pieces of metal from the inside of the container.

Now you can remove the fitting, cutting it flush with the body.

Afterwards, you can use grinding wheel clean the place of burrs.

Further, the order of work will depend on what the functionality of the brazier will be. In particular, you can expand its functionality to the level of a smokehouse, which we will talk about after completing the review of various models of simple barbecues.

Varieties of barbecues from gas cylinders

Most simple solution it will simply cut the cylinder lengthwise into two halves, drill a series of holes on the sides so that the coals “breathe”, weld the legs to the bottom, make slots for the skewers, and the brazier is ready.

But the following method is more popular. Although using this method, two braziers from one cylinder will no longer work, but one will turn out, but much more aesthetic, because it will have a lid, and the brazier will be deeper, because if, as we stipulated in the previous section, we made the lid on 8 cm smaller, the brazier itself has become 4 cm deeper. In addition, due to the lid, you can save longer maximum temperature coals.

In order for the barbecue to become more mobile, a pair of legs on the right or left can be equipped with wheels. Then, by lifting one edge, it can be easily rolled from place to place. In addition, if there are two wheels, the other two legs can be replaced with one, which will simply serve as an emphasis. Also, the brazier can be equipped with a small tabletop for seasonings, cutlery (plates, knives or forks), etc. For ease of transportation, a handle can be welded from the edge opposite to the wheels.

A heavy cast-iron stand from under an old sewing machine is excellent as a bed, which, due to its heavy weight, will reduce the risk of the structure turning over.

Forged parts and a chimney outlet will not only give the structure a more presentable and sophisticated look, but also improve the functionality of the brazier.

Holidays outside the city, whether it is a summer cottage or a picturesque glade in the forest or near a pond, very often involves cooking barbecue. Of course, for this you can get by with a few bricks and a couple of metal crossbars, but the real pleasure of cooking meat on skewers can only be obtained next to a convenient and practical barbecue. A solid construction can be made from thick sheet metal. If there is no such thing on the farm, then you should not rush to the construction market. An excellent device for cooking meat can be built with your own hands from an ordinary gas cylinder.

Features of a brazier made on the basis of a tank for liquefied gas

A gas cylinder is an excellent basis for many homemade designs. Good solid metal, a practically finished form and several standard sizes make it possible to obtain a potbelly stove, an indirect heating boiler, an autoclave and other equipment necessary for the household with minimal labor. The thick walls of the liquefied gas container can withstand high temperatures, so it is the best suited for making a smokehouse, barbecue or barbecue. Other advantages of the design are also known:

A brazier built from a tank for household gas has practically no drawbacks. Some consider large dimensions to be a minus, but what prevents them from taking a smaller cylinder, for example, 27 liters? The negative aspects include perhaps the semicircular shape of the bottom, which is not very convenient during the ignition of firewood. On the other hand, with this configuration, the coals will be closer to the edges of the skewers. Due to this, the outer pieces of meat will be better baked, which, when cooked on a traditional rectangular roaster, often remain raw. Experts believe that the spherical walls of the brazier are not entirely suitable for cooking barbecue, as they interfere with processes that help the rich aroma of baked meat “open up”. In the future, we will touch on this issue, revealing the secret of how to avoid the disadvantages associated with the round shape of the bottom.

Preparatory activities

Before picking up a welding machine, you need to pick up a gas cylinder and prepare it for work, draw up a rough sketch of the future barbecue and stock up essential tool and materials.

Which bottle can be used

For the manufacture of brazier, any gas cylinders of a cylindrical shape are suitable. The best option is a fairly roomy and most common 50-liter container for household propane-butane. If you want to get more mobile and lightweight construction, which can be transported in the trunk of a car, you can take a standard cylinder of 27 liters. In this case, it should be taken into account that the width of the working space portable barbecue may not be enough due to the spherical shape of the sidewalls.

Gas cylinders are made of high-alloy low-carbon steels 30XMA, 45, 34CrMo4, 30XGSA. The high content of ligatures and the reduction in the amount of ligatures in the metal makes the alloy more durable and improves anti-corrosion properties.

An ideal option for a stationary barbecue would be a car gas cylinder of 50–80 liters. It has an increased diameter, so it will be much more convenient to kindle firewood. In addition, such a vessel has a high capacity. Its width makes it possible to use the entire length of a standard skewer, and this will allow you to cook dinner for a large company. The only caveat is that finding an unnecessary car gas tank will not be easy, and buying a new one will not be financially feasible.

Gas cylinders are made of high-quality alloy steel with a thickness of 3 or more millimeters, so even if the container has been standing in the open for a long time, it is likely to be usable. If the vessel is heavily rusted, then you should not waste time on it - it will not be difficult to find a workpiece in good condition.

How to protect yourself from an explosion

Even if the valve of the used container is completely unscrewed and the gas does not come out of it, do not rush to take on the grinder. Despite the fact that inside the cylinder the pressure was equal to atmospheric pressure, most likely, unsafe substances remained in it - propane-butane and condensate. The latter is drained by turning the vessel upside down, and in order to completely remove the explosive contents, the cylinder is filled to the top with water and left for several hours. Only after this requirement is met and the liquid is drained, you can start cutting and welding metal.

Schemes and drawings

The brazier from a gas cylinder is so simple construction that does not require careful design. Nevertheless, at the preparatory stage, it is recommended to draw up a small drawing or sketch of the future structure, indicating the dimensions of all its elements. This will make it possible to determine how much and what kind of rolled metal will be required, and will also allow you to properly plan individual processes. Perhaps the drawings and diagrams presented in our gallery will help you in working on the barbecue.

Materials and tools necessary for work

In addition to the gas cylinder itself, you will need:

• pieces of steel pipes and corners;
• metal handles for the lid of the barbecue;
• door or furniture hinges;
• pipe with a diameter of 100 mm with a 90-degree elbow, if you plan to install a chimney;
• grill, which will be needed for barbecue;
• bolts with nuts or rivets.

In addition, you should prepare decorative elements designed to refine the structure, as well as the primer, paint and solvent that will be needed to paint it.

If we talk about tools, then we are sure that everyone who is interested in the issue of building a home-made barbecue will find them:

• welding transformer or inverter;
• UShM - angle grinder (colloquially "Bulgarian");
• electrodes Ø3–4 mm;
• cutting and cleaning disc for angle grinder;
• electric drill;
• a set of drills for metal work;
• clamps for fixing metal parts;
• long metal ruler;
• scriber;
• core;
• adjustable and gas key;
• set of wrenches.

If, after manufacturing, the brazier will be painted, then additionally prepare a brush attachment for a drill or grinder, as well as brushes or a spray gun with a compressor.

Making a brazier with your own hands from a household gas cylinder of 50 liters

Installation work is best done in a well-ventilated area or outdoors. The place where the assembly will be performed must be fairly even, otherwise it will not be possible to ensure the correct geometry of the structure and the brazier will be unstable.

When carrying out locksmith work, it is important not to forget about the safety rules, be sure to use protective equipment and overalls.

Step-by-step instruction

1. Unscrew the valve. To do this, use a gas or adjustable wrench. Sometimes shut-off valves so strongly sour that there is no way to turn it off. In this case, the tap can be cut off with an angle grinder. Using the same tool, they cut off the lower support rim - with it the design will look unaesthetic.
2. Mark the cutting points. The diameter of the 50-liter propane-butane tank is 960 mm, which allows it to be accurately divided into four parts. It is convenient to take a longitudinal seam as a reference point. Putting the balloon on flat surface, from the welding line in both directions, measure a quarter of the diameter - 240 mm and apply horizontal markings that will divide the cylinder in half. An indent of at least 30 mm is made from the attachment line of the upper and lower parts of the vessel, after which circular lines are drawn. The distance between them is divided into equal intervals of 80-100 mm, on which the skewers will be laid. After that, mark the lid of the barbecue. Its length should be less than half the diameter, so 100 mm are measured from one of the longitudinal lines towards the horizontal weld. A parallel drawn strip will indicate the place of the cut.
3. Having installed a cutting disc on the "grinder", they cut a line that divides the diameter of the cylinder in two. After that, the slot is marked into equal parts and the loops are welded. Their number can be from two to four (depending on size). After that, the cover is cut out along the circular marks, as well as the longitudinal line, which is located at a distance of 140 mm from the horizontal seam.

   Do not rush to cut the entire cover at once. Subsequently, this will entail a lot of inconvenience associated with its correct orientation, setting gaps, etc. It will be problematic to do this without an assistant. If the loops are immediately welded along the line of the first cut, then in the future it will be possible to save a lot of time and nerves.

4. In order for the upper door to be held in the desired position and not to break the hinges when tilted, limiters must be welded along the cut line. You can make them from 20–30 mm pieces of a steel corner with a shelf width of 40–50 mm. Fixing stops are mounted on both sides - this will avoid distortion of the cover.

   The distance at which the door will recline can be changed by unbending the latches to the required angle. At the same time, a position is chosen in which it will be possible to easily reach the handles of the lid, without leaning forward much, and at the same time will not allow the structure to spontaneously slam shut.

5. In order to prevent the door from falling inward when closing, a limiter must be welded around the perimeter of the circular cutouts. To do this, a strip 30–40 mm wide is cut out of sheet steel with a thickness of 1–3 mm. It is attached from the inside of the balloon with an interrupted seam.

   Instead of limiters, you can use a piece of chain of the desired length, welding it with one end to the barbecue, and the other to the lid.

6. Below the loops, a series of drillings Ø12–14 mm are made for skewers. Previously, these places were marked along the dividing line of the diameter. Slots or triangular cutouts are made on the front wall opposite each hole, on which skewers will be placed.
7. Mount handles for opening the lid. For this, factory products with overlays made of wood or refractory composites are best suited - they will not allow you to get burned. In extreme cases, the handle can be made by bending a piece of metal bar or reinforcement in the form of the letter “P”.
8. At the next stage, holes are cut in the bottom of the brazier for air to enter the combustion zone. To do this, the structure is turned over with the lid down, measured from the longitudinal seam 100-120 mm in each direction and horizontal lines are drawn. Setting aside 100 mm from these marks, strips are obtained, in which cuts are made every 50 mm. Drilling can be done instead of slots. In this case, holes with a diameter of 10–12 mm are made in a checkerboard pattern.

   Cutting through the bottom for air supply is impractical for a number of reasons. Firstly, this will weaken the weld, which makes the structure more rigid, and secondly, the holes will quickly become clogged with fatty deposits mixed with ash and ash, and will cease to fulfill their functions.

9. The hole for the valve must be welded. If the brazier is also planned to be used as a smokehouse, then the opening is expanded to the diameter of the chimney. After that, a chimney is welded to the cylinder.

On this, the main part of the work is considered completed. It remains to install the brazier on the legs and ennoble with an interesting decor, or simply paint the structure with heat-resistant paint.

Installation of supports for barbecue

There are several options for installing the brazier on legs, which is facilitated by the rather thick metal of its body. The first and easiest method is to weld four pieces of steel pipe or angle directly to the hull. Of course, the attachment points must be carefully verified, and in the process, use a square and building level, otherwise the design will look askew and untidy. Everyone makes the height of the brazier for themselves, but there is also a standard recommendation - the distance from the ground to the plane of laying the skewers should be no more than 1 m.

It is worth noting that the method described above cannot add presentability and convenience. If you want to get a stylish, practical structure, then for this you need to make a frame-type support. To do this, a pair of side racks is made from a profile metal pipe 20x20x2 mm. In its upper part, a semicircular bed is welded from a metal tire, curved in the shape of a cylinder. Between themselves, both parts of the structure are fixed with the same metal profile so that a kind of underframe is obtained. The balloon is placed on the prepared bed and tacked by welding. In order to make the brazier more mobile, metal wheels can be attached to the legs.

A brazier made from a household gas cylinder can be taken with you when outing into nature. In order for it not to take up much space in the trunk of a car, the supporting structure is made collapsible. All that is needed for this is a 40-centimeter piece of pipe with an internal diameter of 18-30 mm and a 3-meter pipe with a diameter of 16-28 mm. The main requirement is that when pairing them, the gap should be small, otherwise the brazier will be unstable.

By cutting a short piece into four equal parts, couplings are obtained, which are welded to the cylinder at the installation sites of the supports. After that, the brazier is installed on the legs and through drilling is performed to fix them inside the couplings. Pins inserted into these holes make it easy to carry assembled structure- tubes will not fall out. In addition to the sides of the portable brazier, carrying handles can be welded. By the way, during the transportation of the structure, all legs, firewood (or a package of coals) and ignition fluid can be placed inside. Such optimization will save a lot of space in the trunk.

How to bring the design to perfection

The ease of manufacture and other advantages of a brazier from a balloon are somewhat overshadowed by the conclusions of barbecue experts that the meat in them is not as tasty as in traditional braziers. Careful examination of the problem revealed several failures.

• Due to the rounded bottom, the layer of coals in the center and along the edges differs in height. This heterogeneity leads to the fact that the firewood that is on the periphery burns out much longer than in the middle of the bookmark - the heat in the center settles much faster.
• The spherical walls emit infrared rays not towards the kebab, but towards the coals, which further enhances the effect described above.
• Unlike a flat-bottomed structure, the supply of oxygen to the brazier made from a round container is uneven.

It turned out to be quite simple to eliminate the shortcoming that did not allow to get the “right” barbecue. Refinement of the brazier requires the arrangement of a longitudinal duct along the entire length of its bottom. To do this, you need a steel corner with dimensions of 80 × 80 mm and a length of 900 mm. In both of its shelves, holes with a diameter of 12–15 mm are made in increments of 50 mm. The air duct is welded into the bottom so that both of its edges remain outside. The essence of the improvement is more clear from the presented figure.

How to paint to "cheap and forever"

A metal structure must be painted for both aesthetic and practical reasons. Unprotected steel will quickly rust, which will add neither beauty nor durability to the structure. Any heat-resistant paint intended for automobile mufflers is best suited for painting the brazier, however, its high price and complex application technology do not allow us to call this option ideal. The same disadvantages have silicone-based paints, specially created for painting. metal furnaces, fireplaces, barbecues and barbecues.

A cheap and practical material is Kuzbass varnish and similar mineral compounds based on bituminous resins.

The coating should be carried out in 3-4 layers, with a complete intermediate drying after each application. Of course, paint inner surface there is no need for a brazier - a soot coating, on the contrary, will contribute to obtaining an ideal product.

The disadvantages of this method are a long drying time and unpleasant, toxic fumes. In addition, the paint remains fragile for a long time, therefore it requires careful handling. The first 2-3 fires are best done "idle". This will eliminate the smell, make the coating more durable and safe. When the mineral composition is sintered, it will be very difficult to damage it. Practice shows that such a composition does not require updating for decades.

Many options for barbecues built on the basis of a gas cylinder allow you to build a practical, functional and original design. It can be placed under a canopy or in a gazebo, installed in the open air or made completely mobile. A properly built brazier gives a soft and even heat, which makes the kebab soft and juicy. Therefore, all that remains to be desired is good company and bon appetit!

Barbecue is an integral part of organizing a trip to nature, relaxing in the country and receiving guests in a country house. It has become a tradition for many families to gather together at the table under the fragrant smell of the barbecue being prepared. However, more and more often men (and we know that they are the ones who cook the best kebabs) do not so much compete in the quality of cooking meat as they brag about the functions and appearance of the technical “stuffing” of this process - the brazier. Many people are no longer so interested in buying a "leaky box with legs", but they want to do something special. A brazier from a gas cylinder, although it seems, at first glance, to be an ordinary scrap metal, copes with its tasks much more efficiently than any other industrial design. In this article, we will consider in detail all the stages of work related to self-assembly finished product, including the preparation of cylinders, their marking and cutting, as well as helpful tips to work with such homemade equipment.

When looking at such a work of art, you do not immediately understand that this multifunctional brazier is made from recycled materials.

Advantages and disadvantages of a do-it-yourself brazier

Gas cylinders are great for "rebirth" in barbecues and in general in any design associated with heating. They are made of durable steel standard sizes, and they are easy to find in the country and in the garage or buy literally at a bargain price.

Advantages of a brazier from a cylinder:

• Versatile design. All models of gas cylinders are unified. There are not so many varieties that "something went wrong." Accordingly, it will not be difficult to find a couple of identical containers for creativity with a grinder in your hands.
• Heat resistance. The metal will not burn through or deform even after prolonged contact with an open flame.
• Multifunctionality. In such a barbecue, you can cook not only kebabs, but also bake vegetables, as well as smoke and fry.
• Safety. After cooking, you do not need to extinguish the coals with water. For these purposes, it will be enough just to close the brazier with a lid.
• Large volume. In such a homemade barbecue, you will feed not only yourself, but also a large company. Especially if you spend energy on welding a multifunctional unit.
• Availability. The main thing is to have a welding machine and a grinder at hand. This is a relevant moment, because the price of a brazier from a gas cylinder, even taking into account the overpayment for some elements, will eventually turn out to be lower than the cost of the purchased model.

One of the advantages of a homemade brazier is the ability to create a mobile model, which, if you really want, can carefully and imperceptibly for guests, along with snacks and you move to another part of the garden

For work it is better to take a 50-liter bottle. They have ideal dimensions for making a brazier: its diameter is 30 cm and its length is 85 cm.

There are not many disadvantages, but they are also worth mentioning:

• In winter, the metal will cool down very quickly., so to invite friends to barbecue, you have to chip in for firewood. Since it will be much harder to maintain the desired temperature in the barbecue.
• Unsightly appearance. If you do not spend a certain amount of money on the purchase of a special heat-resistant paint, very soon your barbecue will lose its presentation.
• Toxicity. Before using the brazier from gas cylinders, it is necessary to get rid of the remnants of rot and dirt that could have accumulated on inside balloon. Therefore, before starting all work, the cylinders are carefully opened, and all parts are calcined on fire, and only then they begin processing, clean off the dirt.

How to prepare a drawing for making a brazier with your own hands from a gas cylinder

Despite the fact that barbecue grills from gas cylinders are considered devices that are quite simple in design, before resorting to any work, it is better to draw a drawing. The pros do it using special 3D programs. For beginners, simple drawings of a brazier from a gas cylinder with typical dimensions are suitable.

Schemes for marking the main technological holes and the design of a standard brazier, a barbecue brazier, as well as a brazier-smokehouse made of gas cylinders

On the do-it-yourself brazier drawing from a gas cylinder, it is necessary to indicate the dimensions of each component, which will help to correctly and accurately mark up, and, consequently, cut all the details. Such calculations will help determine how much material is needed for work, as well as understand in advance about the options for attaching various structural elements.

One of the main mistakes of beginners is that they forget to mark out a place under the blower. That is why you should not refuse to create such a “hint” that will help you properly organize all stages of work.

At this stage, it is important to decide whether your design will perform one function or combine several. For example, for a barbecue, you need to additionally cut the lid. And for a full-fledged smokehouse, not two, but as many as three cylinders are useful.

What tools and materials are needed for work

For work on cutting the cylinder, arm yourself with a gas cutter or grinder. In the process of work, it is worth taking care of the availability the following materials and tools:

1. Steel pipe with a diameter of 100 mm with a 90 ° elbow (for a chimney).
2. Corners for fastening elements and strengthening the structure.
3. Hinges - you can use elements designed for doors or furniture.
4. Barbecue grill.
5. Rivets, bolts and other elements.

Welding machine and grinder - the main tools when working with metal

What tools and accessories will be needed when working on creating a brazier from a gas cylinder:

• welding machine;
• electric grinder;
• electric drill;
• drills designed for metal work;
• clamps with which you can fix metal components;
• metal ruler;
• electrodes with a diameter of 3–4 mm;
• cutting and cleaning discs for grinders;
• scriber;
• core;
• adjustable and gas wrenches;
• set of wrenches.

How to make a brazier with your own hands from a gas cylinder - step by step instructions with a photo

Before proceeding with any manipulations with gas cylinders, it is necessary to free it from gas residues. Even in an empty container, a suspension of liquid hydrocarbons almost always remains, which can explode on contact with air.

How to properly prepare a propane tank for making a barbecue

Illustration	Action Description
	The first step is to remove the valve. First of all, you need to fix the balloon on the ground. To do this, we “grab” it to the stop. Next, we fix the gas key.
	We increase the "traction" with the help of such a steel pipe, it plays the role of a lever. We do it very carefully.
	After the valve is open, we fill the container with water, you can use soap, and leave our balloon for several days.

During this time, the water will have time to dissolve liquid hydrocarbons, fill the tank again and drain it again. Now our balloon is safe. And you can start the next stage of work.

How to mark up and open a gas cylinder

If we are talking about a standard cylinder of 50 liters, in these designs the outer diameter of the container is 96 cm. This value should be divided into four parts. When carrying out these actions, you will receive a value of 24 cm. Marking should be done along the longitudinal seam. It is recommended to measure all distances from this line. This rule ensures smooth marking without distortions.

You will need to measure 24 cm from the seam on both sides and draw lines. The main thing is not to cut them around the entire circumference and leave a part sufficient for the base of your barbecue.

Side seam option
After trimming “by marks”, the following blanks are obtained

We process the edges as evenly as possible to ensure maximum sealing of the barbecue container

At the place where the valve was present, a pipe should be installed with which smoke will be removed.

Blanks for the future chimney

In order for the heat in your brazier to spread evenly and there were no leaks on it, steel strip linings must be welded to the joints of the lid and body.

This is how you can improve a regular balloon with a pair of gratings, a grinder and metal corners

If you have not welded a corner for skewers inside the balloon, you can insert it into the side parts of the barbecue.

To do this, you need to make cuts with the help of a grinder. The ends of the skewer will be located in them.

How to make barbecue legs

High legs will also require additional fixation, which is provided using a welded corner. It should be placed on the outer perimeter. Mounting the legs can be the simplest and a little extravagant.

For the manufacture of legs, corners or conventional welded pipe structures welded to the structure are often used. The main thing is to ensure the stability of the brazier.

How to weld covers and handles and assemble the entire structure

The lid is usually created at the first stage of work on the brazier or barbecue. After processing the edges, it is practically the first element attached to the main structure. The most difficult moment is not so much to attach the loops as to ensure a snug fit of the structure. Sometimes a thermometer is attached to the lid.

The hinges are welded at the beginning, but the handles are most often fixed after the final painting of the product. In order for the lid of the brazier not to open completely, a piece of a 10 × 10 square must be welded onto the counterpart of the curtain, which is located on the cylinder itself.

Such limiters allow you to control the angle of tilting the lid and keep the hinge from breaking.

We mark holes and slots for skewers. We weld the barbecue guide. Do not forget to decorate our "blower" a little.

It is better to foresee holes in the base of the design. They will save your brazier from dust and dirt and remove excess moisture during rain. In addition, additional holes will contribute to additional traction.

How to paint a brazier

If you think that you can paint the brazier with ordinary paint, then you are greatly mistaken. Under the influence of high temperatures, the usual coating will turn into soot after the first heating. There are two very obvious solutions. The first is to leave everything as it is, and the second is to spend some money on a special heat-resistant paint.

However, before you run for a brush and to the store for paint, you need to do one very important thing. Burn some firewood in our barbecue. This is done in order to destroy the remnants of gas substances and degrease the structure.

It is better to burn the brazier on the street or indoors, where it will be as safe as possible.

The surface of the brazier can be coated different materials:

This is how our brazier began to look after painting

We add that the barbecue model discussed above is the base for many such structures. Most craftsmen improve their homemade products additional cylinders thereby expanding the functionality of the device.

What else can be made from a gas cylinder - manufacturing nuances

On the basis of a gas cylinder, dozens of grill, barbecue and smokehouse variations can be made. For convenience, we briefly describe some of these devices:

1. Open barbecue from a gas cylinder. The simplest type of construction from a gas cylinder. Even a schoolboy can make such a brazier.

   How to make a smokehouse from a gas cylinder

   Consider some of the features of making a smokehouse from two cylinders.

   An example of making a barbecue grill from a gas cylinder with our own hands, we examined in detail in this article. If you still have questions about how to make a barbecue grill from a gas cylinder yourself, watch this video:

   Do-it-yourself barbecue from a gas cylinder

   The role of a barbecue can be played by any of the homemade products discussed in this review. Even an open brazier will perfectly cope with this task. However, it should be remembered that most often such structures are not protected from either wind or rain.

   How to make a brazier-steam locomotive from a gas cylinder with your own hands

   This is one of the most difficult and most time-consuming tasks that real masters of working with metal set themselves.

   It is not possible for a beginner to create such a design. A “homemade” product of this type is capable of solving several problems at once: it is a brazier, a smokehouse, a grill, and a barbecue. Each compartment performs its task. Such braziers have high performance due to the hermetic design, there is practically no heat loss.

   If you decide to create a brazier-steam locomotive, then from this video you will learn how to weld a brazier from a gas cylinder.

   Features of the use of braziers assembled by hand

   Before deciding to create or buy similar product pay attention to some points:

   1. First of all, understand for yourself that any structure that works with fire is potentially life-threatening.
   2. Ask yourself in advance the question of where the product will be stored during the cold season.
   3. Learn the principle of operation of the brazier and its features. Each structural element has its own purpose.
   4. Prepare all materials for the work in advance.
   5. Do not leave small children unattended near power tools, and even more so with a cylinder.
   6. Consider how to buy a brazier from a gas cylinder if you are not completely sure whether you can finish the job yourself.
   
   And it is quite possible that already this summer your neighbors in the area will strive to take a selfie with such a work of art.

A large company that has come to the country needs a solid brazier. Standard thin steel constructions offered in stores are not suitable for this.

It is inconvenient to fry kebabs and steaks on a fire, placing them on bricks. Not everyone will dare to build a stationary barbecue structure with a stove and a roof.

After reflecting on this, the home craftsman comes to the conclusion that the best option- make a brazier from a gas cylinder with your own hands.

The thick walls of such a container will last more than one year. Its dimensions are optimal for laying out skewers. It is easy to choose the height according to your height so that during the cooking process you do not have to bend your back.

There are many varieties of braziers and smokehouses made from gas cylinders. Let's get acquainted with them and talk about how you can independently implement the option you like.

It all starts with cutting the balloon

Regardless of the design chosen, the first step in making a brazier is cutting an old propane tank with a capacity of 50 liters. We do not recommend immediately rushing at him with a grinder. In this case, you must follow the safety rules. Residues of gas contained in each container may explode on contact with sparks and air.

Therefore, you first have to manually unscrew the tap. Removing the fitting on an old cylinder is not always an easy operation, since it “sticks” firmly to the body. You can try to move it with an open-end wrench by hitting the handle with a hammer.

If the tap does not give in, then use another tool - an adjustable water wrench and a steel pipe as a lever.

Under the influence of such a powerful force, any thread gives up. In order to prevent the container from turning, on the other hand, a stop corner is attached to its bottom.

To facilitate unscrewing, you can apply "Vedeshku" to the place of contact of the tap with the body and wait a couple of hours until the thread sags.

After that, the container is slowly filled with water. It displaces a combustible gas-air mixture, eliminating the risk of an explosion when cutting.

After that, the water is not drained, but the tap is put in place and the body is marked out.

There is a long seam on one side of the cylinder body. It will be a "beacon" for the first cut line. The second line is drawn on the other side so that it is opposite the first one and recede from it upwards by 8 cm. This will be the second cut line. If you do not make such an amendment, then the brazier will turn out shallow.

Having made the markup according to the drawing, they take the grinder and cut through the walls, separating part of the body. It will be used as a flip cover.

An important nuance! Cut the body carefully next to the seam so as not to damage the steel ring that is under it. It will serve as a stop for the lid so that it does not fall into the brazier.

In the lower photo on the left side of the container you can see the ring. If the master had passed the grinder next to the seam, then it would have remained in place and served as an emphasis. Correcting the mistake made is easy: you need to weld steel strips on top of the lid.

The next step is to remove the fitting. It is cut flush with the body.

Burrs are removed with a grinding wheel.

The further order of work depends on how you intend to use the brazier: only for frying or combine it with a smokehouse. We will consider these operations after reviewing the finished structures.

Examples of barbecues from gas cylinders

The easiest way to turn a gas container into a brazier is to cut it in half, drill air holes in the sides and weld four legs to the bottom.

We divide the balloon in half and get two braziers

The most popular option among craftsmen is cutting out the sidewall of the case and turning it into a door. It will help keep the coals hot longer when frying.

For ease of transportation, two legs must be equipped with wheels, and the third one should be used as a stop. The transport handle can be made longer and a plate for dishes and seasonings can be fixed on it.

The best brazier bed comes from an old sewing machine bed. It lowers the center of gravity of the structure, preventing it from tipping over.

Forged decor and a side smoke pipe improve the appearance and functionality of the brazier.

Having made a smoke umbrella over the brazier, two tables on the sides and planting it on bent steel legs, we will get a more solid structure. There is no special need for an additional canopy, however, its presence improves the appearance.

Our review continues with a home-made brazier smokehouse from gas cylinders. It is a combination of two containers: 50 liters and 20 liters. The smaller one is placed below the main one, connected to it through a small window and used as a smoke generator. To improve draft, the chimney is made higher.

A more advanced option is to install a third vertical tank. It hangs products for cold smoking. The total capacity of this design is sufficient to prepare meat and fish delicacies in reserve.

Occupying a place of honor on the site, the brazier becomes the subject of general attention. Knowing this, many craftsmen decorate it according to their imagination.

The most popular option is the design in the form of a steam locomotive. The fire and smoke emanating from the brazier fit perfectly into this image.

The smoke generator can be placed crosswise in the "driver's compartment", or it can be naturally incorporated into the overall locomotive design.

The streamlined shape of the container is reminiscent of a submarine. Present to your attention interesting example implementation of such an idea.

To one master, the gas container reminded an underwater ship, and to another, an association with a piglet came to mind. To embody it in metal is not difficult.

Having become acquainted with the samples of folk "mangalo-creation", let's move on to considering the practical issue of how to make a barbecue from a gas cylinder and a smokehouse based on it with your own hands.

Step-by-step instruction

We described the initial operations for marking and cutting the balloon at the beginning of the article. Now we will supplement our instructions with photographs and explain further steps.

It is more convenient to weld the hinges to the body of the brazier until the lid is separated by cutting a line on the back of the body. In this case, they will fall into place without distortions. On the other side, a steel bar handle is welded to the lid.

If you do not put a limiter on the side of the hinges, then the door will fall back when opened and it will be inconvenient to get it out. As stops, you can use a short cut of the corner, welding it in the middle between the loops.

Blower holes can be drilled, but it is easier to make them with a grinder in the form of vertical slots.

To install skewers on the ribs of the brazier, triangular cutouts are made or holes are drilled in the body in increments of 5-7 cm.

Barbecue legs can be made in two ways:

• "In a simple way" from pieces of reinforcement or pipes, welding them to the bottom;
• Having made a stand from shaped pipes and a bent strip, on which the cylinder will lie.

Close the lid to speed up the frying process. In this case, to remove smoke at the end of the container, you will have to make a hole and weld a pipe into it.

The brazier-smoking shed differs from the usual brazier in the presence of a smoke-generating compartment. For this purpose, a cylinder of 20 liters is most often used. Having outlined a hole for passing smoke, it is cut out with a grinder.

The same operation is done with a large capacity. After that, they are joined by welding. A large balloon is placed on legs.

Having drawn the contours of the covers, they are cut out of the cases and put on hinges. At the end of a large capacity, a hole is made for the chimney and welded in.

Inside the cylinders, shelves are made from a corner and gratings of thick wire are placed on them. At the back, holes are drilled in the smoke generator housing and a rotary damper is installed to adjust the draft. A similar damper is attached to the pipe.

Experts strongly advise to put a temperature sensor on the body of the main chamber (upper limit of measurement +350 C). It will help to precisely control the smoking process and get products of excellent quality.

Finishes painting the structure with a heat-resistant composition.
