Gas-burner- This special device, which ensures uniform combustion of gas and allows you to adjust the fuel supply. Often, not everyone can afford similar device, however, a do-it-yourself gas burner made from scrap materials will be an economical and practical alternative to factory counterparts.
The main components for the manufacture of powerful gas burners are industrial valves. They may be new, but homemade device it is enough to use used ones in the absence of gas leakage. They are designed to work in tandem with a 50-liter propane gas cylinder with an angle valve and a reducer.
Burner with valve VK-74
The device of this burner is shown in fig. 1. Based on the valve oxygen cylinder VK-74. To the output end, a machined on lathe fitting-handle, to the corrugated part of which the hose from the cylinder is connected. A cap with a prepared threaded hole for the jet is screwed onto the part of the valve with a K3 / 4˝ conical thread, with which it was connected to the gas cylinder. Can be used ready-made version blowtorch or gas stove.
The nozzle is made from a cut steel pipe 1/4˝ 100 mm long and welded to the cap on two pieces of wire ∅5 mm. A distance of 15 mm should be left between the cap and the nozzle for air to enter the combustion zone. By bending the wire holders, the position of the nozzle is adjusted to achieve the center position of the flame.
The sequence of actions for ignition of the burner:
- Open the cylinder valve;
- Bring a lit match to the nozzle and slowly open the burner valve;
- Control gas ignition;
- Regulate the flame with the burner valve
By the way! The highest flame temperature is at the end of the green-blue part of the torch.
A home-made gas burner of this design has one drawback associated with the peculiarity of the location of the valve. The gas flow is directed in the opposite direction to the normal position. Stuffing box seals experience constant gas pressure (including when the valve is closed), so it is necessary to constantly monitor the tightness of the seals.
Attention! The VK-74 valve should only be used when adjusting the flame. Stop gas supply only at the cylinder
Burner converted from acetylene gas cutter
If you have an acetylene torch with a defective oxygen supply valve, do not rush to throw it away. It will also fit for the manufacture of a burner (Fig. 2.). 
Alterations require a mixing chamber, the contents of which must be removed to reduce weight. You will need to remove the oxygen barrel and valve. Solder the resulting hole with hard solder. Connect the hose coming from the gas cylinder reducer to the M16 × 1.5 left-hand threaded fitting.
With a union nut on the mixing chamber, fix a home-made tip bent at 45 ° to make it more convenient to work with the burner. Screw the flange with the nozzle welded to it onto the thread of the tip.
One of the options for the execution of such a burner is the use of a cap with an M22 × 1.5 thread. The design of the nozzle here is similar to the nozzle of the burner described above. Homemade gas burner is ready to go.
Gas mini burner
Mini gas burners are more suitable for working with small details. The mini burner is based on a ball inflation needle. It is necessary to make a cut in it, a little further than the middle of the needle. Some needles already have a similar hole, which greatly speeds up the work process. Next, you need to take a syringe needle, and bend it about 45 degrees in the middle.
The design of the mini gas burner
The pointed end of the syringe needle is best sharpened so that it is straight. After that, it must be inserted into the ball needle in such a way that one of its ends comes out through the hole, and the other protrudes from the large needle by several mm. The resulting mini design should be fixed with soldering. After that, droppers must be attached to the bases of the two needles. Clamps - Dropper regulators should be moved as close to the needles as possible. In the resulting burner, they will act as regulators for the supply of gas and air. They also need to be fastened together, and this is best done with a thermal gun. It remains only to connect to finished device source of compressed gas, the burner is ready for use. Such a homemade gas burner can heat objects up to 1000 degrees. It should be handled with care and safety precautions.
Infrared heater
The use of homemade gas burners may suggest the idea of \u200b\u200bcreating an infrared heater with your own hands. Such heaters are designed to heat houses or garages, in the face of ever-increasing gas prices. by the most in a simple way keep warm is to use ordinary food foil. It must be mounted on the wall behind the battery. Heat fluxes will be reflected from aluminum surface into the room, which will not allow heat to escape through the walls.
In more difficult variant spiral can be used. To do this, you need to purchase an incandescent spiral and an infrared port in the store. Making such a device is quite simple: the spiral must be laid in a metal block that is connected to the mains. An infrared port is attached to the resulting structure. This device works on the basis of the port's ability to distribute the thermal information received from the hot coil into the room.
For garages or other small non-residential premises, a heater based on a small tin box and graphite sand is best suited. Such a device is quite compact, it does not require much space, while doing an excellent job with the tasks assigned to it. Before starting work, the container must be thoroughly rinsed and dried. It can be of any diameter and size, it is important that it fully fits your ideas about what the future heater should be like. 
Graphite must be mixed with fine sand in a ratio of one to one and half filled in the box. From a sheet of tin, you need to cut a circle with a diameter suitable for an iron container, and attach a lead wire to its edges. This structure must be laid on a mixture of sand and granite, after which it is covered with the remaining mixture. Next, the container must be tightly closed with a lid in order to artificially create pressure inside it. The second wire of the container body is connected to the car battery.
You can regulate the heating temperature of such a device using a cover. With tighter twisting, the temperature of the tin box will be stronger. With less, it will lose heat. It is important not to allow such a heater to overheat. In such cases, the box will begin to glow with a red or orange glow. When overheated, the process of sand sintering occurs, which leads to a loss in the efficiency of the home-made gas burner. To restore it, internally shake the device.
A gas infrared heater is more expensive in terms of materials, as it requires the purchase of a small 
infrared ceramic heater. It is best not to buy a large device, since it will be “powered” by a small propane tank with a volume of 1 liter. In addition, you need a burner - a nozzle with a special tap. First of all, you need to get rid of all the burner nozzles, leaving only the pipe and tap. A hose is put on the pipe, which should be a little more than half a meter long. A gas cylinder is connected to this device. It is very important that it be in a vertical position, since the movement of gas goes up, and not horizontally. Such a heater works for two hours on a conventional 200-gram cylinder.
Fishermen often use a similar device during winter fishing in a tent. The stock of cylinders with gas allows you to comfortably spend the night on the ice. In addition, this design is safe, there is no open flame in it, which can cause harm. Ceramic tiles 10 minutes is enough to fully warm up, after which it begins to actively radiate heat, heating the air around it.
How to make a gas burner with your own hands? Or a heater? Very simple! The main thing is to know the internal structure of these devices in order to have an idea about its operation. After that, the manufacture homemade design won't be difficult. The main thing is not to forget about safety precautions when working with open fire or its sources.
For people actively working in the workshop or in country house often there is a need to heat the part or to solder. These tasks will be solved by a high-temperature gas burner, which you can make yourself. With its help, you can heat parts for subsequent processing or welding, harden parts, carry out roof repairs. This list could be continued.
All these tasks can be solved with a gas burner. Such devices include devices that provide mixing, preheating, supply of the required volume of gas and oxygen. It creates conditions to ensure the required rate of combustion of the resulting mixture and create the required heating temperature.
Such devices are offered on the market a large number of, from specialized professional (for heating boilers, and welding work), to universal household propane burners.
Gas burners manufactured on an industrial scale are considered solely from the point of view of reliability and safety during operation. However, very often, according to the criterion "efficiency - cost", gas burners industrial production can't stand any criticism. In addition, you can purchase a product of dubious quality or made in friendly China.
Having considered in detail the design options for such burners, an unambiguous conclusion suggests itself. In these gas units there is nothing complicated. Therefore, many are trying to make such a device at home. It turns out a convenient and cheap gas burner with your own hands.
Burner classification
The device of a gas burner is quite simple. Modern gas burners are divided as follows:
- premix. The formation of a gas mixture occurs immediately before entering the outlet.
- injection burners. The air necessary for combustion is spontaneously sucked in (as they say, injected) by the gas jet itself.
- Recuperative. The essence of their work lies in the preliminary heating of gas and air. This happens before mixing. The heating itself is carried out by a special device - a recuperator.
- Regenerative. Preheating in burners of this type is carried out in the regenerator.
- Pressurized (gas burners with pressurization). In them, air is forced into the furnace by a special fan. This happens after mixing the combustible mixture.
- Diffusion. By design, these are the simplest burners. They consist of a regular tube with holes drilled in it. Gas is supplied through these holes. To ensure constant and reliable combustion, the necessary air comes from the environment.
- Gas atmospheric burners for boilers. The principle of their operation is very similar to the principle of injection burners. The main difference is that oxygen enrichment is not carried out completely, but partially.
- Gas burners for stoves, fireplaces, heating systems.
The power of any gas burner is determined by the volume of gas consumed per unit of time. For different burners, it can differ quite significantly.
Burner design
A standard homemade burner functions in this way. Under pressure, gas is supplied from a cylinder through a special hose. The most commonly used gas is propane. The volume of supplied gas is changed by a regulating working valve located on the cylinder. Therefore, the installation of an additional reduction gear is not required.
The shut-off valve is located behind the main valve and is attached to the gas cylinder. It is used to open or close the gas supply. All other adjustments (length and intensity of the flame) of the burner itself are carried out using the so-called working tap. Leading gas hose, through which gas is supplied, is connected to a special nozzle. It ends with a nipple. It allows you to set the size (length) and intensity (speed) of the flame. The nipple together with the tube is placed in a special insert (metal cup). It is in it that the creation of a combustible mixture occurs, that is, the enrichment of propane with atmospheric oxygen. Created combustible mixture under pressure enters the combustion area through the nozzle. To ensure a continuous combustion process, special holes are structurally provided in the nozzle. They perform the function of additional ventilation.
The design of similar gas appliances are developed taking into account the convenience in operation, prevention, repair. Therefore, they must be easily collapsible. This simplifies the maintenance and repair process.
Based on such a standard scheme, you can develop your own design. It will consist of the following elements:
- body (usually it is made of metal);
- a gearbox that is mounted on a cylinder (a ready-made device is used);
- nozzles (made independently);
- fuel supply regulator (optional);
- head (the shape is selected based on the tasks to be solved).
The body of the burner is made in the form of a glass. The material used is ordinary steel. This form allows for reliable protection from possible blowing out of the working flame. The handle is attached to the body. It can be made from different material. The most important thing is that it provides convenience during work. Previous experience shows that the most optimal length of such a handle is in the range of 70 to 80 centimeters.
A wooden holder is attached to the top. A gas supply hose is placed in its body. This allows you to give the structure a certain strength. Flame length can be adjusted in two ways. With the help of a reducer located on the gas cylinder and a valve mounted on the tube. Ignition of the gas mixture is carried out thanks to a special nozzle.
Production of a gas burner
Getting Started self-manufacturing devices, it is necessary to prepare tools for work and select the required material. First of all, choose the material for the handle. There are no strict requirements, so everyone can use their imagination and possibilities. The main requirements for the handle are: its ease of use, so that it does not overheat during operation. Experience shows that it is advisable to use a ready-made handle. For example, a handle from some failed soldering iron, boiler or other household appliance.
Steel is used to make the supply tube. Choose a steel tube with a diameter of not more than 1 cm and a wall thickness of 2.5 mm. The made felling is inserted into the prepared handle. There it must be securely fastened. The mounting method is selected in accordance with its capabilities.
The burner body is made of steel. The divider is made of brass rod. Several holes are drilled in the divider body (usually more than four). This will create good oxygen circulation at the burner outlet.
After that, the divider is securely fixed in the body. A small clearance should be provided for the inner flange. The recommended clearance should be approximately 5mm. Such a gap will provide the necessary deceleration of the gas flow rate that enters the igniter. Slowing down will allow more reliable ignition of the burner.
The nozzle is made from a metal rod. It will provide gas supply to the combustion area. It is made in the following way. With a drill with a diameter of 2 mm, a blind hole is carefully made in the nozzle body. Then drill a hole with a 4mm drill bit. It is necessary to create a jumper. They are carefully riveted and polished.
The end of the manufactured tube is connected to the outlet of the reducer. A flexible hose is used for connection. The material is selected from the list of permitted materials for household gas systems. It can be a special rubber or a special fabric material. To ensure reliability and fire safety it is better to use certified material. The hose is put on the tube and secured with a standard clamp.
After completing the assembly of the entire device, you need to set optimal pressure in a balloon. Before lighting the burner, the entire gas supply system, mixing with air, should be carefully checked for possible leaks. If they appear, they must be eliminated. Only after all checks can the burner be ignited. The burner must provide a burning jet length of up to 50 mm.
Properly self-assembled burner will serve as a reliable assistant in business on long term. It will be the tool that will help solve many everyday problems without resorting to the use of an expensive tool.
In a home workshop or garage, there is often a need to use a gas burner. The application for it is the widest - from soldering to roof repair. Not to mention the need to heat up the metal part for processing.
During locksmith work on metal, a gas burner can heat the workpiece for the purpose of subsequent hardening. If you are engaged in electric welding, when working with some metals, it is necessary to warm up the place of the future seam.
Tool stores sell a variety of tools for safe work with fire. A propane burner can be of any size and any configuration. Value from ballpoint pen for jewelry soldering.
Or m Nozzle rail for bitumen heating on the roof:
The advantage of industrial options is the safety certificate. However, there is nothing in the design that cannot be repeated at home. Since any product in the store costs a lot of money, we will tell you how to make a gas burner with your own hands.
Important! Homemade fixtures for working with fire carry a potential hazard. Therefore, a propane burner manufactured without technical expertise is operated at your own peril and risk.
Drawings and step-by-step instructions for making a burner
Let's take a closer look at the nuances that you should pay attention to when making a burner.
- First of all, it is necessary to use refractory metals. A properly adjusted burner can produce up to 1000 ° C, so the nozzle must match the temperature of the flame;
- It is important to choose a reliable working crane. If something goes wrong, the gas supply is first of all shut off, and the danger is eliminated. If the tap skips, you will not be able to quickly extinguish the flame;
- Connection unit to the gas source (canister with valve or 5 liter propane tank with gearbox) must be reliable. It is during the operation of poor quality stop valves most accidents happen.
Many home craftsmen know what a gas burner is. Thanks to it, it is possible to perform welding, surfacing and other types of processing of metal products, heat them and connect them. The principle of operation of such a device is to mix combustible gas and oxygen. As a result, a stable flame can be obtained, which has a huge temperature, which is difficult to extinguish. Such burners can be universal or designed for specific jobs. The fact that the flame is stable makes it possible to use this unit outdoors even in windy conditions. You can either buy it or make it at home. If you are not one of those who are looking for easy ways, we suggest you figure out how to make a gas burner for soldering with your own hands.
Materials and tools for work
To make a regular burner, you will need the following parts and tools:
- Bulgarian;
- hammer;
- sandpaper;
- brass blanks for the nozzle and divider;
- thin brass tube Ø15 mm;
- wooden bars;
- vise;
- FUM tape or silicone seal;
- connecting hoses;
- control valve.
Manufacture of handles and nozzles
Take a brass tube and attach a handle to it. If you have a handle from an old burner, you can use it - it will be much more convenient. If not, you can take a wooden block. To make the handle fit comfortably in the hand, it can be processed. It needs to drill a hole for a brass tube. Their diameter must match. After that, the tube is pushed into the beam and fixed there with silicone or epoxy resin.
For ease of work, the brass tube must be bent above the handle at an angle of 45˚.
The next step is the manufacture of the nozzle. This is a laborious and long process. It needs to be approached with more responsibility. The desired nozzle hole size is 0.1 mm. It is clear that it will be very difficult to achieve this size on your own without special equipment, so you need to drill a hole a little wider and fit the edges to right size. Everything must be done carefully so that the hole is even and does not direct the flame in different directions. After making a hole, fix the workpiece in a vise. Then gently strike the future nozzle with a hammer. This should be done vertically, with a "branch" to the center of the workpiece. Gradually, the part must be scrolled, providing a perfect hole without a slope.
After chasing the part, the nozzle head needs to be sanded with fine-grained sandpaper. The back of the part should be threaded to connect it to the tube. A simpler connection method is soldering the nozzle to the pipe. But it should be noted that in this case, the repair of any parts will be very difficult to perform.
In principle, that's all, now you can connect a gas cylinder to the tube, set it on fire and the unit is ready to work. But, now there are some difficulties that interfere with normal work and bring inconvenience. It turns out that the gas flow can be regulated only by opening and closing the valve on the gas cylinder. In this case, it will be very difficult to achieve the required flame strength. What to do?
Work to improve flame regulation
To ensure the normal operation of our burner, it is necessary to equip it with a divider and a tap. Appropriate place for mounting a faucet near the handle, 2–4 cm higher. But it can also be installed on a supply pipe. A tap from the burner of an expired autogenous burner or its other analogue will do. It is permanently fixed on the tube with a threaded connection. Use FUM tape to seal the connection.
The divider will be installed on the pipe with the nozzle. It also needs to be made of brass Ø 15 mm. Most best option- a cylindrical part with a hole for a tube with a nozzle. If there is none, do the following:
- Take a brass pipe Ø 35 mm and cut a piece of 100–150 mm.
- Stepping back from the end, mark with a marker 3-5 points evenly distant from each other.
- Drill 8–10 mm holes in it with a drill and use a grinder to make even cuts to them.
- Now you can bend everything to the center and weld it to the burner tube.
To properly fix the divider, it must be placed so that the nozzle protrudes 2–3 mm from the junction. Such a device serves two purposes: to protect the flame from strong winds and to provide it with a flow of oxygen, which is necessary for a more stable and stronger flame.
All welding spots can be smoothed out with a grinder. Then your homemade burner will look more solid. That's all. Now it remains only to supply gas and use the burner for its intended purpose.
Making a mini burner
If you need to work with small parts or boards, then such a large torch will not suit you at all. In this case, you can make a small burner from improvised means, which will produce temperatures up to 1000ºC. You will need:
- Regular dropper - 2 pcs.
- Needle for inflating balls.
- Needle for a medical syringe.
- Soldering iron.
- File.
- Copper wire.
- Pliers.
- Grinding stone.
- Flux for soldering.
- Thermal gun.
Armed with all the tools, you can get to work. For convenience, we divide the process into the following steps:
Gas will pass through a thick tube, and compressed air through a thin (medical) tube. You can change the pressure of gas and compressed air thanks to the dropper regulators. Such a small burner will be useful for home use.
Gas-burner - useful tool V skillful hands. In order to have it, it is not necessary to go to the store and spend money on a purchase. Everything can be done by yourself. The main thing is to prepare all the materials and tools, as well as to research the technology for making the burner. Before starting work, we recommend that you familiarize yourself with the design of the tool and the principle of its operation. Then it will be much easier for you to do everything yourself.

Video about making a miniature gas burner:
Almost every man had a need to solder metal at home. The process itself is easy. The only obstacle is that the equipment for this process is not always available. home master. gas bottle there is, but there is no special burner for this. Let's try to do without autogen and make it for soldering simple burner. It should be noted right away that it will not give the same powerful flame stream as its industrial counterpart. This means that you will not be able to weld heavy structures. But to solder simple products or repair small metal structures you will be able to.
A gas burner for soldering and repairing small metal structures is useful in any household.
Necessary materials and tools
To make a burner you will need:
- brass tube;
- brass blanks for the manufacture of a divider and nozzle;
- plates of any heat-resistant material (wooden bars can be used);
- vise;
- electric drill;
- sealing FUM tape (or silicone);
- gas reducer;
- connecting hoses.

How to make a pen and nozzle?
The design of a homemade gas burner and the connection diagram to the cylinder.
First, a handle must be attached to the brass tube. For this, they usually use either a handle from an old soldering iron, or in a regular wooden bar drilled longitudinal hole with a diameter corresponding to the diameter of the brass tube itself. Next, the handle is attached to the tube using epoxy or silicone. It is given a form convenient for you.
Especially carefully it is necessary to approach the manufacture of the nozzle. It is desirable that the nozzle opening be about 0.1 mm. It is impossible to drill such a hole at home, therefore a wider one is made, and its edges are minted to the required size. This work is very accurate, so it will take you a lot of time. For the reliability of all actions, the workpiece is fixed in a vise and struck with a hammer vertically with a slight “pull” to the center.
The whole procedure is carried out in a circle to avoid deviation of the direction of gas supply in the future. After embossing, the nozzle head is processed with fine sandpaper. On reverse side nozzles are threaded for connection with the inlet pipe. Soldering is often used to connect the nozzle and tube. Note that this is far from The best way connections: if necessary, it will be very difficult to repair or replace the nozzle.

How to improve flame regulation?
In general, the described version of the manufacture of the burner can be considered already completed: your unit will work, you just need to connect everything together, open the gas cylinder tap and ignite the gas. But then some inconvenience will go further, since it will be possible to regulate the gas flow only with a gas cylinder valve, and maximum power you won't get the flame. The burner needs to be equipped with a crane and a divider. The valve can be mounted both on the burner itself and on the inlet pipe. It is more convenient when it is in the immediate vicinity of the handle (2-4 cm higher). The crane can be used from an old autogen burner or another analogue. It is better to permanently fix it on the tube on threaded connection, sealing with FUM tape.
The divider is made of brass. The best option- This is a cylindrical blank with a hole for the supply tube and parallel holes of smaller diameter. Such a blank is attached to the tube in such a way that its edges protrude 2-3 mm forward from the edge of the nozzle. Such a small device will do two things: it will protect the flame from crosswinds and provide the flow of oxygen necessary to maintain a stable flame.

How to simplify the divider?
To equip the divider, it is not necessary to make such complex structure. A brass tube with a diameter of several larger diameter supply tube. Such a tip must be fixed on the tube parallel to it. The air flow will be provided due to the fact that the gas leaving the nozzle will create a zone of low pressure, respectively, the air flow will rush into this area on its own.
The principle of operation will be the same as that of a conventional tourist stove. The difference between a home-made stove and a primus stove is that it is much smaller and uses gas instead of gasoline as a fuel. And the gas burner does not require the creation overpressure inside the container with gas, since it is already present.
A homemade burner is completely unpretentious to the composition of the gas: it works both on pure propane and on a propane-butane mixture. The difference will be felt only in the rate of heating of the material during the soldering period. But even this moment can be leveled by adjusting the gas supply.
