Gasification of the population makes itself felt, so many propane cylinders with a capacity of 50 liters were not needed. So that good does not disappear, we offer a selection of devices to make life easier. What can be done with a gas cylinder - see below.
Before doing something from a cylinder, safety measures must be observed, since propane gas is very dangerous.
Open the faucet and release the gas. This is done away from an open source of fire. Then, we put an empty cylinder on the ground, hit the crane with a sledgehammer, it breaks off in the place where it is twisted into a cylinder. Next, pour water through the hole formed. The water fills the balloon and displaces the remaining gas. To avoid the smell of the mercaptan odorant, it is necessary to fill it with bleach or wash it with a solution of bleach. Very good result for the weathering of the smell of gas, calcination of the cut cylinder on a fire until the paint burns gives.

Simply and easily
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 bed sewing machine. 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 tank 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 reverse side corps. 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.
It is difficult to argue with the fact that relaxing outside the city at your own dacha is a real pleasure. After all, only at such moments of life you can truly feel the freshness of nature, cook fragrant kebabs and chat with loved ones.
Residents of large cities, who have to live in the constant bustle of the city, especially agree with this. For such citizens own dacha outside the city is a real salvation, where they can take a break from the annoying atmosphere of the metropolis.
Naturally, in such a country house it’s easy you need a brazier, because it is an extremely convenient means of cooking on fire, ever invented by people. Cooking on the grill began in the distant past, however, even in our time, many people are not averse to using this technique.
Brazier from a gas cylinder
Nowadays, a barbecue with a smokehouse is an indispensable attribute of any country cottage. As a rule, many summer cottages may have a different house plan, size, layout, but any self-respecting owner of his own summer house has his own brazier with a smokehouse.
To reduce the cost of such a device to a minimum, it is best to make a brazier from a gas cylinder with your own hands. Such a smokehouse will practically not differ from that bought in a store, and the amount of money that will have to be spent on it will be the minimum figure.
Advantages of a do-it-yourself brazier
Since the advent of barbecues, a person has constantly upgraded his device, adding new functions to it, making it more convenient, and so on. Thus, from the usual frying of meat on a stick, on a fire, we came to modern microwave ovens. Hence, assortment of barbecues so wide that everyone can freely choose the model that he likes.
However, prices are usually modern models braziers are simply prohibitive and not many can afford such a luxury. That is why this article was created - because many people are wondering how to make a brazier from a gas cylinder with their own hands.
So, below we will look at the list of advantages as well as disadvantages of the design that we will be doing:
Pros:
- Large sizes that allow you to cook at a time a large number of food for a big company.
- Lightweight design, which is not difficult to make even for those who are not tied to physical work in any way. All you need is a gas cylinder and a few hours of time that you will have to spend on creating your own smokehouse.
- Extremely low cost grill. Such expenses can be afforded by anyone who has his own dacha.
- Rugged and durable construction that can withstand the highest temperatures. Due to this, the durability of your barbecue also increases.
- In the case of a hinged lid, the brazier will not have to be brought under a canopy in case of rain. Plus, a brazier cover is necessary in order to use it as a smokehouse.
Minuses:
- The first advantage of such a brazier can also be called a disadvantage. The fact is that a large structure cannot always fit into the yard of a summer residence, especially if its area cannot boast of large sizes.
- Brazier and smokehouse from a gas cylinder will not portable design, which can be rearranged at any time to more comfortable spot. In order to transfer such a structure, you will need at least 2 people.
- Of the raw materials that can be used as fuel for the barbecue, only coal can be used, since there is too little space for firewood in it.
The production process of a brazier from a gas cylinder
First of all, you need to find suitable gas bottle. In principle, this can not be difficult, especially for those who have survived the time of refueling gas stoves using gas cylinders. To make our barbecue, you will need a large gas cylinder with a capacity of about 50 liters.
I would like to warn you right away that the manufactured brazier and smokehouse will not have a presentable appearance. However, this will not affect the quality of cooking. It's a matter of taste. Of course, you can specially equip it so that it looks neat.
It is also worth knowing that if you don't have a welding machine, as well as the ability to use it, then you will not succeed. In this case, the only way out is to contact a specialist in this industry. In principle, this cannot be called a significant drawback of the manufacturing process, since it will not be difficult to find a competent welder who has his own welding machine.
Tools and materials that will be needed in the production process
So, in order to make a brazier from a gas cylinder with your own hands, you will need the following tools:
- Bulgarian;
- two door hinges for cover;
- a set of tools that includes:
- hammer;
- screwdriver;
- wrench;
- chisel;
- drill;
- corner;
- metal pipe.
Manufacturing instructions
The first step is to cut the balloon. This process is quite unsafe, so all security measures must be observed. Make sure the gas bottle exactly empty and free of gas.
When cutting the cylinder into 2 parts, be extremely careful, because if there is even a little gas left in the cylinder, it can ignite freely and bring a lot of problems.
So, when the cylinder is cut into 2 parts, you need to wait until all the remaining gas has evaporated. After that, you need to turn the cylinder upside down in order to drain all the condensate.
In order to remove an unnecessary tap on the surface of the cylinder, you can use a hammer or grinder. In the first case, it can simply be beaten off from the balloon, in the second, it can be completely cut off. The second case is less secure, so we recommend a hammer.
After you have done all the above steps, you must completely fill the bottle with water and leave it like this for a few days. After that, working with such a design will become absolutely safe and you can do whatever you want with it.
How to make a cover?
As you might have guessed, top cover brazier is an indispensable attribute. First, it is rain protection. Secondly, this is the introduction of the smokehouse function, without which your barbecue will not be so functional.
So, we will make a lid for the barbecue from the already cut off part of the balloon. The cap must be cut off from the cylinder from the upper part of the body along the middle. It is necessary to cut it from the middle to the edge. After that, it is attached to the main part of the brazier with the help of door hinges that we prepared earlier. Side walls must be left.
Assembly of the top
When the top cover is ready for operation, it is necessary to qualitatively attach it to the main part of the brazier. To do this, we need, as mentioned earlier, door hinges and a drill.
First of all, using a drill, we drill holes for the hinges, after which we fix the latter with rivets and weld them. Again, if you do not have a welding machine or the ability to use it, contact a specialist who, for a small fee, will solve all your problems.
Here you can get a little creative. You can attach additional accessories to your brazier, such as a lid handle. You can also build a removable cover by directing the hinge axes to one of the sides.
Strengthening and fixation
In order to avoid the possibility of deformation of your future barbecue due to high temperatures, necessary strengthen the base of the smokehouse.
To do this, a metal corner must be welded around the entire perimeter. It is best to do this inside the barbecue. Thus, you will kill two birds with one stone: strengthen the base and create a convenient support for the net or a skewer from a regular corner.
It is also best to make incisions so that the skewer fits perfectly into its place and holds steady there.
Naturally, any barbecue or barbecue should have its own legs. This has not bypassed our case. For legs, regular ones are best. metal pipes
the same length. There should be four.
To fix them, it is necessary to drill holes in the corners of the bottom, after which we fasten the legs with nuts. If after this the legs of your brazier turned out to be not stable enough, weld additional hijackings from below.
On top of all the work - drill a few holes in the bottom of the brazier for burnt coals.
Results
So now you can easily do excellent brazier from a balloon with my own hands. Moreover, as you could understand, this process does not take much effort and is extremely simple.
If you approached the whole process with all seriousness and did everything right, then such a design can serve you for more than one year. And here you can not only fry kebabs, but also smoke various products.
Believe me, if you make it yourself functional product, it will serve you for more than one year, which is good news.
Optimization of heating costs country house is a very urgent task for its owner: what to use as fuel, which thermal unit is the best. Home-made gas cylinder stoves are very popular, 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 or conservatories need to be heated regularly.
Therefore, home craftsmen are constantly developing and implementing additional thermal units of the most 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 furnaces from cylinders reaches 85–90%, which is a very high figure compared to homemade ovens 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 at the lowest 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. Each home master makes his own changes to them, corresponding to the capabilities 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 a radiator heating system or water heating in an indirect heating boiler. As a container for heating, it is convenient to use gas or oxygen balloon, passing the chimney pipe along the axis of the vessel. A fitting is welded in the upper part for hot water, at the bottom - for the return. 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. For the manufacture of the simplest furnace necessary:
- Install a pipe with a diameter of about 100 millimeters in the upper part of the cylinder.
- About 30 holes with a diameter of 10 millimeters must be drilled in the walls of the pipe.
- Place a bowl-shaped container with a diameter of 120–140 mm with sides 25–30 mm high at the bottom of the cylinder.
- 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.
- 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:
- Open the cock on the fuel tank and pour used oil into the bowl up to about the middle of the walls.
- 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.
- 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.
- 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.
- 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 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 fins 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. 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.

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:
- Separate the head dome of the cylinder using a grinder.
- Make a hole in it along the axis with a diameter of about 80 millimeters. Since the domed part will later be used as a cover, two bar handles must be welded to it. The cap will have to be removed every time you load fuel.
Cut off the top of the cylinder - a detail for the manufacture of the cap
- In the bottom of the cylinder, make a hole of approximately the same diameter. Its purpose is periodic cleaning of combustion residues. This hole must be closed with a reliable damper.
- Approximately 5 centimeters from the top edge of the body, you need to make a hole for the chimney pipe. Usually it is a pipe with a diameter of up to 15 centimeters with a wall of at least 4 millimeters.
- At a distance of approximately 10-12 centimeters from the bottom of the cylinder, drill three holes with a diameter of 10 millimeters. They are arranged in a circle at an angle of 120 degrees with respect to each other. Bars with a diameter of 9.0–9.5 millimeters are inserted into the holes so that they protrude inward by 20–25 millimeters. Outside, the bars must be welded to the body.
- Cut out a circle with a diameter of two millimeters less from a sheet four millimeters thick inner size corps. Drill 20-25 holes in it with a diameter of 10 millimeters. This part will play the role of a grate.
- Install the part on the protrusions of the pins.
- Next, you need to make a piston, which will also perform the function of a load. The piston is made up of several simple details. The first is a pipe with a diameter of about 80 millimeters with a wall of up to four millimeters. It is allowed to use an electric-welded straight-seam pipe. The second part is a pancake, in the center of which you need to cut a hole equal to the diameter of the pipe. The pipe is welded to the pancake at a right angle coaxially.
Fins on the pancake provide air for fuel pyrolysis
- Ribs are welded to the lower surface of the ring from a strip with a width of about 40 millimeters or a corner of the appropriate size. They are located from the center to the edge of the pancake. The number of ribs is 4–6 pieces.
- A damper must be installed at the upper end of the pipe in order to be able to completely close the hole in the pipe.
Flue gas outlet and damper to shut off the air supply
The order of laying fuel and ignition of the furnace
The sequence of actions in this case is as follows:
- Fuel preparation consists in grinding large fragments to the state of technological chips (5x20 mm) and mixing it with sawdust and shavings.
- Pour fuel into the furnace; at the same time, it is necessary to compact it, achieving the highest mass density.
- Lightly moisten the surface of the fuel insert with lighter fluid.
- Install the piston in the furnace body with the pancake down, fully open the damper on the pipe.
- Close the lid.
- 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.
Photo gallery: how to light the bubafonya stove
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:
- 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.
- 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.
- 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 extracting energy for heating through radiator system heating.

Calculation of the main parameters of the furnace "Bubafonya"
The efficient operation of a furnace 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 optimal thickness walls are recognized as 4–5 millimeters. 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, than larger 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 specific energy fuel burning for an hour, 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 the 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, corners, 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 according to 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, so regular inspection is necessary. inner surface chimney. If necessary, it must be cleaned. Inspection is carried out at least twice a year.
On long-burning furnaces, an insulated stainless steel pipe is mandatory.
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.
At self-manufacturing there are no trifles for heating stoves. Each circumstance must be carefully weighed and thought out. Otherwise, all efforts will be in vain. I wish you success!
Going out into nature with a large company involves cooking barbecue and other dishes, for this it is enough to find an acceptable place. On suburban area or country terrace you can not do without a barbecue, a tool that provides the opportunity to cook delicious barbecue or meat alone. If create beautiful barbecue, it will fit into any interior of the site and give uniqueness. Making a brazier is possible with your own hands, using improvised means, such as a gas cylinder or a pipe.
Types of barbecues
Charcoal cooking is possible in many ways. Brazier has proven itself on the positive side, has a number of advantages and is divided into several categories.
- Portable structures are used for frequent movement. Advantages include low weight and simple design, as well as the availability ready-made options On the market. The functionality of such braziers is modest; additional devices will be needed to prepare dishes that differ from kebabs.
- Portable barbecues have more solid construction, this category includes a brazier from a gas cylinder. The design can be moved inside the site or in a car trailer, has better functionality, is quite simply made by hand from improvised materials.
- Stationary braziers are installed in the foundation, have a solid structure and a lot of weight. The main features are the design of the structure, which, with a creative approach, can decorate a summer cottage.
In more detail it is worth considering the brazier from the cylinder, because. this device has all the functionality of a stationary one, it is mobile. Thus, a do-it-yourself barbecue from a gas cylinder can save the owner financial resources, because store models with similar parameters are not cheap. The design can vary in size, regardless of the cylinder used, which makes it possible to accommodate a large number of dishes for cooking with a large company. The height can be adjusted by welding on the legs, which makes the process of frying kebabs convenient and ergonomic. Also, with the help of improvised tools, it is possible to make decorative look, which will give uniqueness, add beauty to the summer cottage.
Preparation for manufacturing drawings and optimal dimensions
Before cutting the prepared cylinder, you need to remember safety precautions. Sedimentary vapors always remain in gas cylinders, which, when interacting with a spark or welding, can lead to unpleasant consequences.
The manufacture of a brazier from a gas cylinder begins with the emptying of the container, for this the main valve is unscrewed, the gas is vented. The procedure is performed with extreme caution, in a well-ventilated area, away from sources of fire or direct sunlight. It is possible to visually verify that the cylinder is empty using soap solution, it is enough to apply it to the outlet nozzle, observe the formation of bubbles. If gas escapes, respectively, soapy water begins to bubble, after which it is necessary to unscrew the valve wrench, completely remove it from the cylinder.
After bleeding off the gas, it is necessary to turn the gas container over, drain all the condensate. Then under with great pressure water is supplied, which will displace residual vapors, remove condensate completely. Drainage of water must be carried out far from residential premises, the properties of the gas are such that a fire can occur at a low concentration. Compliance with the sequence of all procedures makes the work safe for humans.
To make a brazier with your own hands, you need to use the drawings. The dimensions are selected in accordance with the volume and shape of the cylinder, with standard equipment the height is 98 cm, the diameter is 30 cm. The wall thickness of the gas container is standard, but may differ from the direct purpose of the cylinder, it is 0.3 cm, the weight of the cylinder is 22 kg.
Cylinder marking
Before making a brazier from a gas cylinder, it is necessary to mark it according to the required parameters. To mark, ordinary chalk is used, the process is as follows:
- A certain diameter is 96 cm, it is easily divided into equal parts. For uniformity, markings are made along the longitudinal seam.
- Marks for placing skewers are set in a horizontal position, 24 cm in each direction recede from the seam.
- The device of the cover is carried out according to the deviation of 3 cm from the seam.
- 10 cm deviate from the two lines obtained, this is done for parallel fastening of the legs in the future.
- The cut lines under the cover act as borders, which are applied at the first stage (24 cm of indent).
- If there are inner rings in the design of the cylinder, it is necessary to work carefully so as not to damage them. In the future, they will play the role of a lid holder.
Layout and dimensions of the future brazier in the drawing
Work on the manufacture of barbecue does not require special drawings. It is necessary to mark the parameters of the future barbecue based on the size of the balloon. A specific barbecue scheme from gas cylinders is not required, it all depends on the functional accessory, the size of the device. The height of the cut and cover is regulated by the combustible means used. If ready-made coals are used, it is possible to cut the cylinder in half; in case of burning firewood, the lid should be higher so that the blanks do not fall out.
Choice of gas bottle
Used for gas grill suitable material including the balloon. You can find the appropriate barbecue cylinder in the country if propane was used gas-burner, at scrap metal collection points or private ads. gas grill It is standardly made from a cylinder with a capacity of 50 liters. The main selection criteria is the whole body without rust and oxides, in order to prevent further destruction of the finished product.
Tools needed for the job
For quick work, you need to prepare the appropriate tool. You will need a set of home master tools, as well as a few additional things:
- grinder or grinder;
- welding machine of any type;
- personal protective equipment, glasses, gloves;
- metal door hinges in the amount of 3 to 5 pieces;
- rivet gun, rivets;
- chisel, hammer;
- screwdriver, wrench;
- drill with a set of drills (a drill of 10-12 mm is required);
- pipes for the chimney and legs, the latter are used materials from unused sewing machines.
The use of tools requires certain skills, the material of gas containers is quite thick, not every novice master will be able to competently cut, weld metal.
How to properly open a propane tank
Safe work is achieved through well-executed preparatory work. The washed cylinder must be cut into two halves with a grinder, the process is carried out as close as possible to the weld. The side walls are not dismantled, their purpose is to protect the fire from the wind, to maintain temperature indicators. support rings do not cut, their task is to keep the lid closed.
How to paint
From an aesthetic point of view, it is necessary to paint the balloon. The process is the choice of each individual, it is not at all necessary to spend time and effort on it. To paint the brazier from a gas cylinder, you should use high-quality components that do not decompose under the influence of high temperatures, without changing taste qualities food.
Before painting, a primer layer is applied, which is selected on the market in accordance with the type of paint. Before purchasing, you should study the purpose and instructions, the temperature of the paint should be more than 600 degrees. As a rule, these materials are environmentally friendly, so it is possible to paint the building not only from the outside.
We make a brazier from a metal cylinder
For country use, an ordinary barbecue is often not enough. It is possible to make a barbecue with your own hands from a gas cylinder. For this you need to follow step by step instructions, in this case, you get a beautiful, high-quality product.
- The hinges for attaching the lid to the body can be welded on before cutting, so that they are installed evenly, without distortions in relation to the top. The cover is fastened to the body with a metal bar.
- The limiter must be installed on the back of the brazier to prevent the lid from completely lowering. So it will be convenient to close and open the device during use.
- Blower holes can be drilled, but it will be much faster to cut them with a grinding tool. Vertical slots are made along the entire length, holes for attaching skewers are drilled with a drill with the required distance.
Barbecue legs can be made independently different ways, it is also possible to use a ready-made stand from the old sewing machine. The frying process in accelerated mode implies a closed lid; a pipe must be mounted to remove smoke. A balloon barbecue is made by adding corners to the structure in the inner part, for attaching a mesh or metal bars.
Brazier steam locomotive
The design, called a steam locomotive, combines several devices at once, has rich functionality. The device is used as a grill, barbecue, smokehouse and a regular barbecue. Each component has significance, certain functions.
Brazier "Steam locomotive"
The design of this type of barbecue from a gas cylinder resembles a steam locomotive, if you make an effort to appearance. Additional designs allow you to store firewood, products, etc. When making a locomotive, it is equipped with all sorts of details to increase the functionality of the device. Brazier steam locomotive from a gas cylinder allows you to simultaneously smoke products, cook vegetables and fry shish kebab, an indispensable device for a large company.
Features of a brazier made on the basis of a gas cylinder
Self-manufacturing makes it possible to select the necessary parameters, the functionality of the equipment. Braziers from gas cylinders are popular among owners of summer cottages and houses. Installation additional elements Allows you to cook a variety of foods in a variety of ways. The offered models on the market often do not meet the wishes of the client, there are no height adjustments or the design is not capacious enough.
Advantages and disadvantages
All devices have a number of positive and negative sides. The brazier from gas-balloon equipment became famous for its simplicity of design and other qualities:
- a simple manufacturing method allows not even experienced master build a brazier, having tools, fixtures, as well as a visual aid;
- the use of improvised means excludes financial costs, monetary losses entail only a tool, some additional elements;
- long service life is due to the thick metal in the walls of the cylinder, the manufactured part is not subject to temperature effects or mechanical damage;
- flip-top lid allows you to cook your favorite meals on outdoors under adverse weather conditions;
- the mobile design allows you to carry the brazier on the site or in the car, a reliable bottom makes it possible not to fill the coals with water, but simply cover the brazier with a lid.
Disadvantages of a brazier from a gas cylinder:
- the dimensions of the structure may not always allow you to move, install the brazier in the right place;
- the weight of the structure is large, so moving without special devices alone is impossible;
- the use of firewood will delay the cooking process for a long time.
The nuances of using the received product
correct technical operation makes it possible to use the manufactured structure for a long time. During downtime, it is better to clean the structure indoors to avoid exposure to direct sunlight and the formation of corrosion.
Odors are eliminated by burning the inside of the brazier. The design must be used away from flammable parts, as a spark may jump out during operation. After use, it is recommended to pour out the ashes, high-quality raw materials can continue to smolder for up to several days.
