Do-it-yourself gas burner. Do-it-yourself gas burner on propane: step-by-step instructions for assembling homemade burners. Manufacture of handles and nozzles

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. The size of a 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 devices 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;
• The connection to the gas source (canister with valve or 5 liter propane tank with reducer) must be reliable. It is during the operation of low-quality shutoff valves that most accidents occur.

Consider a typical scheme and the principle of operation of an injection burner:

Gas is supplied under pressure through the hose (1). Usually propane. The pressure is formed due to the evaporation of liquefied gas in the cylinder, and it is enough to organize a stable and directed flame. A reducer is not required, the amount of gas is regulated by a working valve (2).

The stopcock is located on the cylinder valve. Its function is only to open / close the fuel supply, the rest of the adjustments are made using a working valve.

The use of gas fuel is inefficient without the use of special burners.

Today, the market offers a considerable selection of designs, from professional ones that create temperatures up to 1500 degrees and above, to household devices that are needed for heating and cooking.

Nevertheless, self-production of these devices by home craftsmen is a common thing. The reason is simple - a do-it-yourself gas burner, adapted to a specific task and working conditions, is more convenient, even if it costs more than a factory one.

According to the purpose, the devices are divided into professional and household.

Gas is also dangerous, even household gas, as evidenced by accidents associated with explosions or poisoning.

The power of a propane burner depends on the diameter of the injector and nozzle. It must be remembered: it is not the gas itself that burns, but its mixture with air (oxygen).

The larger the volume that reacts, the stronger the torch. At the same time, the danger of getting a dangerous proportion of propane with air in the injection chamber increases, and as a result, a small explosion - cotton.

Therefore, a homemade burner does not need to be too large. As a rule, the injector diameter does not exceed 3-5 cm, and the jet opening is 0.5 mm.

Important! Work in a ventilated area or outdoors. Use gloves to protect your hands.

What to do?

Before proceeding to manufacture, we select the appropriate type of burner from the following list:

1. atmospheric injection;
2. ejection;
3. supercharged.

The second and third types are more difficult to manufacture. And to organize pressurization, you need compressed air or oxygen, which means a compressor or another cylinder.

The easiest way for self-execution will be the first type, it is he who should be preferred.

The atmospheric burner process is controlled by a control valve. Therefore, the choice of type, as well as the model of the device itself, largely depends on which one turns up.

It must be remembered that the combustion of a particular gas depends on the diameter of the orifice of the jet. A hydrogen jet has slightly less of it, a propane jet has more.

Designs, diagrams, drawings, assembly technology

First of all, you will need a drawing of the future device, a sketch or diagram of the burner, with dimensions.

It is easy to find ready-made using the Internet. If you represent the general principles of operation of the device, own the methodology for its calculation, you can develop a project yourself.

As a simple option, use a valve from a propane or oxygen cylinder, known as the VK-74 model (see diagram).

A fitting is machined to the side thread, which will simultaneously serve as a handle. You can use a suitable size pipe. On one side, cut an internal thread, on the other, make a shank for putting on a gas hose.

We screw the cap onto the thread with which it is attached to the cylinder. We drill a hole in its end, cut the thread for the jet. We weld a nozzle to the plug on steel knitting needles, which will simultaneously serve as an injection chamber.

Even easier if you come across an old acetylene torch or gas cutter. In fact, this is a finished burner. It is enough to remove, so as not to interfere, the parts associated with the supply of oxygen, replace the gas nozzle with a jet, fix the injection chamber-nozzle above it.

Mini

A very tiny gas burner can be made from a basketball inflator, a syringe needle and a couple of droppers, or as they are called medical "systems" of drug drip. Homemade work can even work from a can for refilling lighters.

Adjusting roller clamps will play the role of valves.

True, we need a forced air supply to this device, for the injection of atmospheric air the nozzle diameter is too small. For this purpose, you can use an aquarium compressor, or an old refrigerator.

At the needle of the syringe and fitting, carefully grind off the tip. After that, slightly bending the syringe needle, insert it into the side hole of the fitting, so that the end slightly comes out of the cut tip.

We wrap the needle insertion point with copper wire, solder it well with acid.

The burner is ready. It remains to connect gas and air to it.

Nozzle and handle - manufacturing options

If you look from the side, the handle and nozzle, in fact, the entire unit. The rest is pipes and valves supplying gas.

For the nozzle, you can purchase a brass jet from gas appliances. They are sold without problems, they cost a penny.

If you need a special design, you can do the following.

We clamp a suitable workpiece with a vise.

In order not to crush the thread, when clamping the part in a vise, use a regular wooden clothespin first.

Carefully drill a hole with a drill of a suitable diameter, not reaching the end of about a millimeter. We grind the remaining metal until a point appears, left by the very tip of the drill.

After that, with a thin drill or a hardened awl, we punch a hole of the desired diameter from the inside.

Any suitable object can be used as a handle. A handle from an old soldering iron, a piece of thick-walled hose, a drilled piece of wood will do.

To fix parts and hoses, we use clamping clamps, glue of a thermal gun.

The burner flame is adjusted and adjusted in the following ways:

1. gas control valve - current;
2. moving the nozzle (jet) along the axis of the injection chamber, changing its opening.
3. changing the size and shape of the supply window through which atmospheric air enters.

The last two methods are used when setting up. During operation, they do not need to be changed. However, if you are not sure about the accuracy of the design calculations, you should take care of the possibility of adjusting them.

A couple of words behind the curtain

As you can see, there is no particular difficulty in how to make a burner. This task allows you to show creativity, ingenuity with imagination. There are countless possible solutions.

At the same time, it makes sense to make it yourself out of interest. Or when you need a device with unusual characteristics, a factory analogue, which seems unnecessarily expensive.

Greetings to those who love to craft, today we will close up a powerful outdoor burner. The principle of its operation is similar to a blowtorch, and there is no less power. Almost anything that burns can be used as a fuel source for such a burner, it can be alcohol, gasoline, kerosene, and so on. Everything is assembled quite simply, on such a burner you can cook, take it with you to nature, heat pieces of iron, and even melt some non-ferrous metals. If you are interested in homemade, I propose to study the project in more detail!

Materials and tools used

List of materials:
- iron wire (thick for legs and thin);
- ;
- dropper;
- bottle;
- a suitable pump (to raise the pressure in the bottle).

List of tools:
- plumbing pipes (we will bend the coil on them);
- ;
- or a drill (to make a nozzle).

Burner manufacturing process:

Step one. Coil
To begin with, let's make the most important burner assembly - this is the heating coil. A flame will burn inside this coil, from which it will heat up. The coil is made of a copper tube and fuel flows through it. Of course, in a hot tube, the fuel instantly turns into gas and leaves the nozzle at high speed, a closed cycle is obtained.

We take a tube of a suitable diameter and twist a coil of copper tube around it. As for the number of turns, the author has about ten of them, which is quite a lot and five should be enough.

Next, we need to twist the coil around the existing one, it will heat up less, this will allow us to connect a rubber hose to the coil. For such purposes, we need another pipe of a larger diameter so that the manufactured coil can enter it. Here we are already doing about 5 turns and centering the outer coil over the inner one. We leave a piece of the tube longer so that you can connect the rubber hose. That's it, the heating element is ready.

Step two. Nozzle
Let's make a nozzle through which hot combustible gases will escape. The nozzle is a hole of small diameter, the diameter of the author corresponds to the tip of a pin. If you make the hole large, you can get too big a flame. We make a hole in the tube, and expand the end of the tube to clog the end. We bend the tube so that the nozzle is directed inside the coil in the center.

Step three. legs
We make legs for the burner, we bend them from thick iron wire. We fasten the legs to the body with a thin iron wire. If you wish, you can come up with other legs, you can even make a small oven or stove.

Step four. Assembly and testing
We connect a dropper to the burner, with the help of which it will be possible to regulate the supply of fuel. But it is better to use a more reliable hose for connection, since such a thin hose from a dropper will surely melt and fly off with all the consequences.

We connect the other end of the hose to a bottle with a pump. For the burner to work, you need to increase the pressure in the bottle so that the fuel goes through the tube.

Today we will tell you how to make a simple, reliable and convenient injection gas burner for forging and casting with your own hands.

Hello readers and subscribers of the site!

Materials required for the manufacture of a homemade injection gas burner:

• * roofing gas burner;
• two pieces of black pipe 40x3mm (length: 40mm, 50mm);
• one piece of black pipe 25x3 (length: 155mm).

*- a lot of people bother and make a burner from a bunch of plumbing fittings and welding tips, faucets. For what? All this is sold in the store in the form of a roofing torch (take an average nozzle size for normal performance). And we just have to redo the nozzle!

By the way, speaking of the snot. If you are now wondering why something needs to be redone when there are ready-made burners. Just the one I'm going to redo. So the answer is simple. And I demonstrated it clearly in the video. With a short nozzle, the burner will not burn in a closed space! The injection process of air leakage will not work and the flame will go out.

The tool required for the manufacture of an injection gas burner:

• welding machine;
• Bulgarian.

I indicated all the dimensions on the drawing and marked them in the video **

**- Also on the picture displayed ANALOGUE! It can be assembled from transitional cast-iron plumbing couplings and pipes. It will also work well. For me, price is key! I bought pieces of pipe at a metal warehouse and they cost me a little more than 50 rubles + welding expenses, etc. The price of the nozzle rose to 50r! couplings are much more expensive (remember, I have a super-budget starter kit!).
Well, I told you about what I used and why I used this and not another. And you will see a visual production in the video!

p.s. The burner flame burns steadily and very efficiently. Combustion occurs in its outer part. The burner is well cooled by the air flow and remains cold for the entire time of operation. Only the tip is heated, which only contributes to the combustion of gas.
Thank you for watching!

You can make a gas burner for soldering yourself. The design has a different configuration. Often the dimensions do not exceed the length of a ballpoint pen. It is used to heat the metal for the purpose of subsequent hardening or welding. In some cases, a burner is made to heat the bitumen on the roof. Homemade devices are much cheaper than purchased analogues.

Description of the principle of operation

In some cases, a little heat is applied. This is required when it is necessary to dismantle a press fit part. For example, bushing or bearing. This is especially applicable to cases where the parts have different coefficients of expansion. Heating is also used in jobs where welding cannot be used.

DIY manufacturing process

To make homemade equipment, you need to consider some of the nuances:

• The output device gives a temperature of 1000 degrees. Therefore, refractory metals are used in the manufacture.
• An important condition for safe operation is a reliable crane. In the event of an accident, it must quickly cut off the air flow.
• Reliability of the gas connection.

A manual gas burner for do-it-yourself soldering can be made in the form of a miniature fixture. For the manufacture of such mini-equipment, you will need materials:

• brass or copper pipes;
• a block of wood;
• silicone or fluoroplastic as a sealing material.

The drawing of the device consists of a body in the form of a pipe ending with a nozzle. On the other side, a gas supply hose is installed. The nozzle is equipped with a divider for adjusting the flame.

A do-it-yourself gas burner for soldering is made in the following order:

• A tap is attached to the tube with silicone.
• On the other hand, the tube is muffled and a hole of 0.2-0.3 mm is made in it. For this, a special drill and chuck are used.
• After that, the burner is clamped in a vice and the hole is flattened to 0.1 mm with a hammer.
• Sandpaper removes all burrs.

The divider can be made from a brass tube that is larger than the diameter of the burner. Mounting is carried out parallel to the body. The system will work on the principle of a tourist stove. In the place where the gas comes out of the nozzle, a vacuum is formed and air is sucked in.

Device with two needles

A miniature do-it-yourself propane burner is made from 2 needles. One needle can be taken from the pump, and the other from the syringe. You will also need two droppers and a compressor from the aquarium. The device is connected to a cartridge for charging lighters. You will also need copper wire.

The temperature in such a burner reaches 1000 degrees. It is made in the following order:

The gas coming from the canister is mixed in a thick needle with the air coming from the compressor. The composition of the mixture is changed by regulators.

If there is no compressor, you can replace it with a plastic bottle:

The burner is ready for use.

The design of the device with piezo ignition

A portable gas torch with piezo ignition for soldering is characterized by the formation of a stable flame. The device consists of a cylinder that contains gas. A nozzle is installed on top. It is attached with a hose-adapter.

This design does not require heating, it does not clog and odors do not accumulate in it. It has small dimensions, weight and cost.

The task of the piezo ignition is to automatically ignite the fuel. This is convenient when there are no matches. However, this is also the most vulnerable part of the design. With proper care, it will last a long time.

A gas burner for soldering at home is a necessary thing. With its help, copper and brass items are repaired. These are the parts that make up radiators and heat exchangers. The device is of great help during the repair of the car body, when high temperatures can cause metal warping.
