Gas burners: mini for soldering, plumbing and blacksmithing, heating, roofing. Do-it-yourself gas burner: manufacturing instructions Homemade gas burner for heating with household gas

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.

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.

In this article, we will look at how a do-it-yourself gas burner for soldering is made. This device is often in demand both in the private sector and for commercial purposes - for individual technical creativity and various construction tasks. In particular, with the help of gas burners soldering, plumbing and blacksmithing, roofing, jewelry work is carried out, and a flame whose temperature exceeds 1500 ° C is also obtained for other purposes.

In plumbing, using a gas burner, you can heat a metal blank so that in the end it turns out to be sufficiently hardened. When carrying out welding work with some metals, the places of future seams must be warmed up.

Parameters for making a soldering torch

First, the device must be made of refractory metals. With a properly adjusted burner, temperatures in excess of 1000°C can be achieved.
Secondly, the burner must be equipped with a reliable working valve that, in the event of a dangerous situation, will shut off the gas supply.
Thirdly, you need to use a reliable connection to a tank with a valve or a 5-liter propane tank with a reducer, which will eliminate the risk of accidents.

Below is a typical diagram and principle of operation of an injection gas burner:

Gas is supplied under pressure through the hose (1) - usually propane. When the liquefied gas in the cylinder evaporates, pressure is created - enough to provide a stable directional flame. Here, a reducer is not needed; a working valve (2) is used to adjust the volume of gas.
The jet enters through the supply tube (3) to the nozzle, and to the nipple (6), which sets the direction of the fire, which is located in the insert (5). This liner mixes gas and air. In the nozzle, the screw fixes the liner. The burner is collapsible, so the nipple can be cleaned.
From the liner, the mixture of air and gas is fed into the nozzle of the nozzle (8). There, oxygen further saturates the mixture. With the ventilation holes (7) stable combustion is achieved.

With these dimensions, the burner is designed for cylinders up to 5 liters.
How the insert is arranged - we will consider separately, the dimensions are shown in the drawing:

The inner diameter of the liner tube (1) must be 0.5 mm smaller than the inner diameter of the nozzle. A washer (2) with air holes is welded inside. The sleeve (2) fixes the tube with the nipple.

The design is different in that when the tab is moved in the nozzle, it is possible to adjust the suction of air through the ventilation holes - and as a result, adjust the temperature of the fire in a wide range.

Making a gas burner from scrap materials: step by step

List of materials and tools:
drill;
Bulgarian;
hammer;
sandpaper;
blanks made of brass for the nozzle of the divider;
thin brass tube with a diameter of 15 mm;
wooden bars;
vise;
silicone sealant or FUM tape;
hoses for connection;
valve for adjustment.

How to make a nozzle and a handle

First of all, we take a brass tube and attach a handle to it - for example, from an old burner, or from a wooden block, having processed it before that. In the bar, we drill a hole for a brass tube with the appropriate diameter. Putting the tube into the timber, we fix it with silicone or epoxy.

Important! To make it more convenient to work, we bend the brass tube above the handle at an angle of 45˚.

Next, we proceed to a more time-consuming and lengthy stage of work - the manufacture of the nozzle. The hole size should preferably be 0.1 mm.

With a drill, you can make a slightly larger hole, and then adjust the edges to 0.1 mm. The hole must have the correct shape so that the flame is even.

After that, we fix the workpiece in a vise, take a hammer and carefully, in a vertical plane with a “branch” to the middle of the workpiece, strike the future nozzle. We evenly scroll the product to form an ideal hole.

Then we take sandpaper with fine grit and skin the nozzle head. To connect to the tube, a thread is applied to the back of the product, and the elements can also be simply soldered - but in the future the repair of parts will be more difficult.

Now we attach the device to the gas cylinder and set it on fire - the do-it-yourself burner is ready to go. However, here you can see that to adjust the gas flow, you can only open and close the valve of the gas cylinder, and in this way it is very difficult to obtain the desired flame. What we can do?

How to improve flame control

For the normal operation of our home-made unit, we will install a divider and a crane on it. It is better to mount the faucet near the handle, at a distance of about 2–4 cm, but it can also be mounted on the inlet pipe. As an option, take a burner tap from an old autogen or another similar tap that is threaded. To seal the connection, we take the FUM tape.

The divider is installed on a pipe with a nozzle, it is made of brass, diameter 15 mm. The best option is a cylindrical part, where there is a hole for a tube with a nozzle.
If it doesn't exist, do this:
1. We take a brass pipe with a diameter of 35 mm and cut off a piece of 100–150 mm.
2. We take a marker, step back from the end and mark 3-5 points, with an equal distance between them.
3. We drill holes of 8–10 mm in the pipe, take a grinder and evenly make cuts to them.
4. We bend everything to the center and weld it to the burner pipe.

For proper fixation of the divider, we place it in such a way that the nozzle protrudes 2-3 mm from the junction. Due to such a device, the flame will be protected from strong winds, and will also be fed by a flow of oxygen and maintain a stable and strong combustion.
We smooth all welding places with a grinder - so our unit will have a more presentable appearance. Now the burner is ready! We bring gas to it and you can get to work.

Do-it-yourself burner: video

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 nozzle for pumping basketballs, 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 point. 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.

For owners of suburban real estate, and just for those who like to make things useful in the household, from time to time there is a need to solder something. A gas burner is well suited for this purpose, with which you can heat parts for their subsequent processing, solder or repair the roof.

Agree, now it is not a problem to purchase a high-temperature burner at a hardware store, but such a device will cost several times more than a home-made one. And the burner will work no worse than the factory counterpart.

From our material you will learn how a do-it-yourself gas burner is assembled on propane, what tools and materials will be required for this.

Before proceeding with the independent manufacture of a gas burner, it is worth understanding its design features and the principle of operation.

As a rule, a propane burner consists of the following elements:

• frame;
• lever;
• distribution nozzle;
• gas tube;
• propane tank;
• clamps for fastening.

Propane is supplied through a hose from a pressurized cylinder. The volume of gas is regulated by a working valve on the cylinder, but for safety reasons it is worthwhile to additionally install a reduction gear.

A shut-off valve is used to open/close the gas supply. It is behind the main valve. The intensity of the flame is adjusted using a working tap.

At one end of the gas hose through which gas is supplied, a special nozzle is attached, at the end of which there is a nipple. The nipple, together with the gas tube, is placed in a metal cup, where the combustible mixture is actually created.

Having familiarized yourself with the design features of the device, you can begin to create a gas burner with your own hands, especially since it is not as difficult as it might seem at first glance.

DIY Instructions

Next, we will talk about several options for homemade propane burners that you can do with your own hands. In order to build the simplest burner, a lot of strength and skill will not be required, but the creation of the other two options will have to work harder.

Option 1 - the simplest burner from a piece of pipe

The construction of such a burner will require very little time and effort. But the process of creating a homemade product must be approached with all responsibility, because you will have to work with an explosive substance and any error in the design of the device can lead to sad consequences.

Using such a device, you can heat metal blanks for forging or warm them up before welding, and you can also repair a bituminous roof. For the owner of a private house, such a homemade product on the farm will definitely not be superfluous.

A properly made propane burner will last a long time. With its help, you can perform many household tasks without the use of a number of expensive tools.

To make a homemade gas burner, you will need the following tools and materials:

• two pieces of pipe of different diameters;
• union;
• gas hose;
• reducer;
• propane tank;
• welding machine;
• Bulgarian.

Having prepared all the tools and materials, you can begin to assemble the propane burner. But before that, we recommend that you read the rules.
