Alcohol burners are useful for those who like fishing, hunting, and hiking. In one of the previous materials we talked about using a vessel from an asterisk. Today we'll look at a way to create a larger burner using an aluminum can. Many may wonder why make an alcohol burner if dry fuel is sold in stores. Dry fuel can also be used to brew coffee or prepare hot tea while camping, but practice shows that an alcohol burner does this much better and more efficiently.

Let's watch a video of an alcohol burner from the author of the homemade product:

What do we need to make a homemade alcohol burner?
- Aluminum can for soda, beer or other drinks;
- Round nose pliers;
- Four matchboxes;
- Stationery knife;
- Medical alcohol;
- Felt pen or marker
- And scissors.

First of all, we must cut off the top of the jar. To do this, we need to make a cut with a stationery knife and tear off the unnecessary part with pliers.

Next, we put two matchboxes, a stationery knife on them with the blade towards the jar and cut off the lower part.

The same procedure will be done with the top of our aluminum jar, but this time with four boxes.

We apply two matchboxes to the cut off upper part, but this time we do not cut it, but outline it with a felt-tip pen or marker.

On the resulting line we place marks or dots every centimeter and make cuts with scissors so that they start from the line to the very bottom of the piece of the can.

Our alcohol burner is almost ready, and all we have to do is assemble its component parts into one whole. To do this, lightly fold the bottom of the top piece of the jar so that it fits easily into the second.

All that remains is to pour medical alcohol into our burner and test it.

Attention!!! Medical alcohol, like the burner itself, is flammable. When using it, be sure to follow the fire handling and safety rules. Keep the burner away from flammable materials and mixtures. Do not add too much alcohol as this may cause the burner to explode and cause serious injury.

- another extremely useful thing in the household of a craftsman who works with metal. It is needed for many things: from soldering work to welding with preheating of workpieces or places of future welds.

Since the functions of gas heaters are the widest, their types are numerous and varied. Models for jewelry work resemble graceful pens. And devices for heating bitumen for roofing work are more like powerful spotlights. All of them are presented on the market: as they say, for every taste and budget.

The purchased model has one advantage - it has a safety certificate. If, according to the conditions of your work, the presence of such a certificate is mandatory, then there is nothing to think about: you need to buy a gas burner. But if you work independently, and official paper doesn’t make you hot or cold, then a DIY gas burner is an excellent solution in all respects.

Why and why? Firstly, this thing is not cheap. Secondly, the design is not too complicated, you will be able to do it, we promise. Before you make a gas burner with your own hands, you need to take into account some special information.

How welding works with a gas torch occur.

Features of gas burners:

• The first thing is the material from which the nozzle should be made. Only refractory metal, because your device must produce really high temperatures - up to 1000 ° C, so the nozzle must be stable at such temperatures.
• We don’t skimp on the crane, because your safety will depend on its quality. If a leak suddenly starts, the gas supply is instantly shut off using a tap. The faucet must be of high quality; it must not leak.
• Another element of the device, the quality of which must be of the highest quality, is the connection point to a gas cylinder with or without a reducer; if the cylinder is small, then it has a valve. We remember that the overwhelming majority of gas-related accidents occur precisely because of a defective shut-off device.
• Propane is most often used - this is for your information.
• At its core, a gas burner is an evaporative type nozzle.
• A gas torch for do-it-yourself soldering is, in principle, no different from a device for hardening metal parts, so it can be made for a wide variety of applications.

How does a gas burner work?

The mechanism of action of the injection type device:

1. Gas is supplied through a hose as a result of the pressure that is generated during the evaporation of liquefied gas inside the cylinder. This pressure is sufficient to ensure that the incoming gas is sufficient to create and maintain an even, constant flame. Not all cylinders have a reducer; in this case, the gas flow can be regulated by a working tap.
2. The shut-off valve is by no means functional, it has a completely different function, it is attached to the cylinder valve with the only task - to open or close the gas supply.
3. A gas stream is supplied to the nozzle through the gas supply tube. This tube goes into a nipple, which shapes the direction of the flame. This nipple, together with the gas supply tube, is located in a special liner, the function of which is to mix gas with air.
4. The insert, together with the nipple and the gas supply tube, is adjusted with a screw. It is best to make the device collapsible, since the nipple must be cleaned without fail.
5. After formation in the liner, the mixture of gas and air is supplied to a special nozzle of the nozzle, into which an additional portion of oxygen is supplied from atmospheric air. The nozzle needs ventilation holes; they will make the flame more even and stable.

Homemade burner options

We already know that one of the main elements of the device is the valve. Powerful, large-sized models must be equipped with industrial-type valves. These valves can be purchased, or you can use old ones while maintaining integrity and providing that there is no gas leakage.

With such dimensions, a standard 50-liter gas cylinder equipped with an angle valve and reducer is used.

Burner with valve VK-74

Cylinder and gas burner.

The main thing to remember is that this valve should only be used to regulate the flame. You only need to stop the flow of gas at the cylinder itself. VK-74 is a valve for an oxygen cylinder, to which a handle with a connected hose from the cylinder is attached. A cap with a hole for the jet is also screwed onto the valve; here you can use an element from a blowtorch or gas stove. A nozzle made of refractory steel on two wires is welded to the cap.

In order for air to enter the combustion zone, the distance between the cap and the nozzle must be at least 15 mm. The position of the nozzle is determined by wire holders so that the burner flame passes exactly in the center. How to light a flame: slowly open the valve by holding a lit match to the nozzle. The flame is regulated by a valve.

Burner converted from acetylene gas cutter

A homemade one is perfectly made from an acetylene cutter whose oxygen supply valve has failed. In this case, the mixing chamber needs to be reworked: everything needs to be removed from it to make it lighter, this also applies to the tap and oxygen barrel. The remaining hole needs to be soldered.

The reducer hose from the cylinder must be connected to the fitting. For ease of operation, the tip is installed at an angle of 45° using a union nut on the mixing chamber. Weld the nozzle to the flange, which is then screwed onto the thread of the tip. We make the nozzle in the same way as in the first version with the VK-74 valve.

Gas mini burner

Drawing of a gas burner.

This is called “minor” work - for example, jewelry. In this mode, it is most convenient to use a special mini-device. This one is made very simply from scrap materials. The main element in it is a needle for inflating balls. You need to work with this needle: first make a hole in the form of a cut approximately in the middle or a little further. Some needles already have such holes, then we are happy and continue to work.

We take another needle, this time from a syringe, bend it at an angle of 45°. The end of the needle should be sharpened so that its sharp end turns into a right angle cut, and the needle becomes like a narrow metal tube. We insert the syringe needle into the ball needle so that both ends come out of the larger needle. In this position, the needles need to be soldered to each other. After this, we connect droppers with clamps to regulate them to the base of the needles.

The clamps should be located as close as possible to the needles and fastened to each other - they will serve as valves, that is, regulate the supply of gas and atmospheric air. After connecting the gas source it will be ready for work. With all its simplicity and compactness, you can achieve temperatures of up to 1000° on it. And don’t forget safety precautions, you need to work very carefully with this baby.

So, building a gas burner with your own hands is a) real; b) profitable; c) useful. To do this, it is enough to decide what kind of work you are planning to determine the type and dimensions. The design of a gas burner is simple from a physical point of view; the main thing is to follow our advice regarding the main elements. We wish you quick solutions, high-quality valves and an even flame.

A gas burner is a special device that ensures uniform combustion of gas and allows you to regulate the fuel supply. Often, not every person can afford such a device, but a do-it-yourself gas burner, made from scrap materials, will be an economical and practical alternative to factory-made analogues.

The main components in the manufacture of powerful gas burners are industrial valves. They may be new, but for a homemade device it is enough to use used ones if there is no gas leak. They are designed to work in tandem with a 50-liter propane gas cylinder, which has an angle valve and a reducer.

Burner with valve VK-74

The structure of this burner is shown in Fig. 1. The oxygen cylinder valve VK-74 is used as a basis. A fitting-handle machined on a lathe is installed at the outlet end, to the corrugated part of which the hose from the cylinder is connected. A cap with a prepared hole with a thread for the nozzle is screwed onto the part of the valve with a conical thread K3/4˝, with which it was connected to the gas cylinder. You can use a ready-made blowtorch or gas stove.

The nozzle is made from a piece of 1/4˝ steel pipe 100 mm long and welded to the cap on two pieces of ∅5 mm wire. A distance of 15 mm should be left between the cap and the nozzle to allow air to enter the combustion zone. The position of the nozzle is adjusted by bending the wire holders to achieve a central flame position.

Sequence of actions to ignite the burner:

1. Open the cylinder valve;
2. Place a lit match near the nozzle and slowly open the burner valve;
3. Control gas ignition;
4. Adjust the flame using the burner valve

By the way! The highest flame temperature is at the end of the green-blue part of the torch.

A homemade gas burner of this design has one drawback associated with 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! Valve VK-74 should be used only when adjusting the flame. Stop the gas supply only at the cylinder

Burner converted from acetylene gas cutter

If you have an acetylene torch with a faulty oxygen supply valve, do not rush to throw it away. It is also suitable for making a burner (Fig. 2). The mixing chamber requires modifications, the contents of which must be removed to reduce weight. The oxygen barrel and valve will need to be removed. Solder the resulting hole with hard solder. Connect the hose coming from the gas cylinder reducer to a fitting with a left-hand thread M16 × 1.5.

Using a union nut, secure a homemade tip bent at 45° to the mixing chamber to make it more convenient to work with the burner. Screw a flange with a nozzle welded to it onto the thread of the tip.

One of the options for such a burner is to use a cap with an M22 × 1.5 thread. The design of the nozzle here is similar to the nozzle of the burner described above. The homemade gas burner is ready for use.

Gas mini burner

Mini gas burners are more suitable for working with small parts. The mini burner is based on a needle for inflating balls. 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 significantly speeds up the work process. Next, you need to take the syringe needle and bend it about 45 degrees in the middle.

Mini gas burner design

It is best to sharpen the pointed end of a syringe needle so that it is straight. After this, it needs to be inserted into the ball needle so that one end comes out through the hole, and the other protrudes from the large needle by several mm. The resulting mini structure should be fixed using soldering. After this, droppers must be attached to the bases of the two needles. Clamps - dropper regulators need to be moved as close to the needles as possible. In the resulting burner they will act as gas and air supply regulators. They also need to be fastened together, and this is best done using a heat gun. All that remains is to connect a source of compressed gas to the finished device, the burner is ready for use. This homemade gas burner can heat objects up to 1000 degrees. You should work with it carefully, observing safety precautions.

Infrared heater

Using homemade gas burners may give you the idea of ​​creating your own infrared heater. Such heaters are designed to heat houses or garages in the face of ever-increasing gas prices. The easiest way to retain heat is to use ordinary food foil. It must be mounted on the wall behind the battery. Heat flows will be reflected from the aluminum surface into the room, which will not allow heat to escape through the walls.

In a more complex version, you can use a spiral. To do this, you need to purchase an incandescent coil and an infrared port in the store. Making such a device is quite simple: the spiral needs to be placed in a metal block, which is connected to the electrical network. An infrared port is attached to the resulting structure. This device works based on the ability of the port to distribute thermal information received from the hot coil into the room.

For garages or other small non-residential premises, a heater made from a small tin box and graphite sand is best suited. Such a device is quite compact, it does not require much space, and at the same time copes well 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 matches your ideas about what the future heater should be like.

Graphite must be mixed with fine sand in a one-to-one ratio and fill the box halfway. From a sheet of tin you need to cut a circle with a diameter suitable for the iron container, and attach the lead wire to its edges. This structure must be laid on a mixture of sand and granite, and then covered with the remaining mixture. Next, the container must be tightly closed with a lid 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 the lid. When screwed tighter, the temperature of the tin box will be higher. If it is less, it will lose heat. It is important not to let such a heater overheat. In such cases, the box will begin to glow red or orange. When overheated, the sand sinteres, which leads to a loss of efficiency of the homemade gas burner. To restore it, shake the inside of the device.

A gas infrared heater is more expensive in terms of materials, as it requires the purchase of a small infrared ceramic heating pad. It is best not to buy a large device, since it will be “powered” by a small propane cylinder with a volume of 1 liter. In addition, a burner is required - 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. The gas cylinder is connected to this device. It is very important that it is in a vertical position, since the gas moves upward and not horizontally. This heater operates for two hours on a regular 200-gram cylinder.

Fishermen often use a similar device when winter fishing in a tent. A supply of gas cylinders allows you to comfortably spend the night on the ice. In addition, this design is safe, there is no open flame that can cause harm. Ceramic tiles only need 10 minutes to fully warm up, after which they begin to actively radiate heat, heating the air around them.

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 of ​​​​its operation. After this, making a homemade structure will not be difficult. The main thing is not to forget about observing safety precautions when working with open fire or its sources.

Hello everyone, today we will make a gas Bunsen burner from improvised materials! This will not be just a stationary burner, but a burner that, if necessary, you can safely hold in your hands and not be afraid of getting burned. Making it will not be difficult; all the materials used must be at hand, and the scope of its application is quite wide.

The author often uses a gas stove in his works, but working with it is not very convenient, so he was struck by the idea of ​​purchasing something less bulky and convenient. Having rummaged around on AliExpress, as well as visiting specialized stores, he found a lot of burners, but as is usually the case, the price did not suit him and so he decided to assemble such a burner himself, especially since all the necessary parts were at hand.

There was an old and cheap Chinese burner available, which served him faithfully for several years. It has a suitable gas supply regulator and it fits cylinders that are sold in every hardware, construction or fishing store.

It will be needed specifically for adjustment. So, let's begin! First you need to unscrew the standard burner, put on a long silicone hose of a suitable size instead and put it aside for now. By the way, if necessary, you can screw the standard burner back if necessary!

To make a new burner, the author used tubes from an air conditioner with an internal diameter of 8 and 5 mm. You can take any copper tube. First you need to cut a piece of tube with a diameter of 8 mm, a length of 10 cm and clean it from the resulting jagged edges, from the inside and outside.

Now you need to saw off a piece of a thin tube about 4 centimeters.

To make a nozzle, you need to cut off a piece of a medical needle.

When biting off a needle, the edge may become dented, so it needs to be cleaned with a file and then cleaned with a thin wire.

The end of the thick tube needs to be crumpled with pliers so that the needle fits tightly into it.

Next, the author used orthophosphoric acid. With its help, he processed a crushed piece of tube with a needle and soldered thick copper wire, and soldered the gap in the tube.

He then soldered a second piece of tubing as shown in the photo below. The author recommends rinsing the acid treatment areas with water to wash off excess and prevent oxidation of the copper tube and needle.

Now you can immediately check the burner; to do this, you need to connect the set aside silicone hose, which the author connected to the Chinese burner at the beginning, and connect the other end to the new burner.

The author's first test of the burner was not particularly successful; it ignited poorly and went out almost immediately. Then he noticed that if you cover the bottom of the burner with your fingers and reduce the oxygen supply, the flame is quite well regulated.

So it needs adjustment! To do this, the author took an M8 bolt, something like the one in the photo below.

I straightened the wire that holds the two parts of the burner so that the needle rests against the wall of the thick tube. Then I drilled a hole for the bolt with a size 7 drill, at the very beginning of the thick tube. In order for the hole to turn out normal, the author recommends first drilling with a thin drill, and then drilling with a thick one. He then took a tap and cut a thread for an M8 bolt.

With a bolt, the flame does not go out and you can regulate the air supply.

In order to make the adjustment more reliable and to prevent the copper thread from quickly slipping off, the author recommends strengthening it with a metal nut. A rectangular shape like the one in the photo below is best.

To do this, you need to take a file and clean all the solder joints.

Next, you need to attach the nut to the soldering point, fix it, to do this you need to screw the bolt first into the nut, and then into the thread on the tube and solder it well on all sides. Don't forget to treat all soldered surfaces with polyacid!

This is what he ended up with.

Due to the fact that the bolt cannot be screwed in all the way, the needle will never be pinched or damaged!

The result is a fairly nice and comfortable burner, you can easily hold it in your hands and work.

When the gas passes through the tube, it cools it, and the flame practically does not touch the burner, so the copper tube does not heat up so much that it burns your hand. This burner is convenient for heating the lock in the garage in winter, since gas cylinders usually do not work in sub-zero temperatures, you can put the cylinder under your jacket to keep it warm, and use the burner even in severe -50 degrees.

In order not to constantly hold the burner in his hands, the author decided to make a stand for it. To do this, you need to make two wire loops on the burner. The loops need to be made by eye, approximately as in the photo below. Be careful when soldering them, as all connections can simply fall apart from overheating!

After the loops are soldered, file any protruding parts of the wire to give the burner a more beautiful appearance.

Now you need to make a tripod for the burner. To do this, the author took a piece of thick plywood and drilled a hole at the edge with a thin drill. He inserted a piece of thick copper wire into this hole. The burner is installed on a tripod using soldered hinges; it does not fall off it and holds quite well.

What is a gas burner? Many people are interested in the exact answer to this question. In short, this is a homemade propane device that has a huge number of advantages over its analogues. In this article we will try to understand exactly everything related to a homemade gas burner, and also answer the question “How to make a gas burner with your own hands?”

Firstly, I would like to note Key Features of this design. These include:

• extremely easy to use;
• no unpleasant or harmful odors, traces of soot, etc.;
• compactness, allowing the gas burner to be used almost anywhere.

The device of a homemade gas burner includes:

• metal case;
• gearbox;
• nozzle;
• fuel supply regulator;
• head;
• a unit for securing a gas cylinder.

The metal case includes a special glass, with the help of which the mechanism eliminates the possibility of blowing out the flame. This also includes a metal or other handle that does not exceed 100 centimeters. A wooden holder and a gas hose are installed on top of the handle. Using a reducer and a tube with a valve, the gas supply level and its length are adjusted accordingly. The nozzle is used to ignite the fuel, in this case the latter is propane.

Type of fuel the burner runs on

As mentioned earlier, a gas burner is also called a propane burner. From this it is easy to conclude that, as a rule, propane or a mixture of propane and butane is used as fuel.

With this fuel a special cylinder is filled, which is attached to the burner.

Do-it-yourself gas burner production

As you can understand from the list of elements of the entire design of the device, it is extremely simple and does not have any complex parts that require a lot of time.

In order to make the unit with your own hands, it will take a little time and effort. And if you correctly study the material presented in this article, as well as approach the process with all seriousness and accuracy (since the work is carried out with flammable substances), then it will definitely be completed.

As practice and many living examples show, on average, a person who has never created homemade gas burners, 40-45 minutes after reading the instructions, could already boast of a homemade burner.

How to make a gas burner with your own hands

Here we come to the most interesting process. To make a burner. Below we will describe in detail the entire process of creating this unit, taking into account all the nuances and tips.

So, you should start with the simplest, but no less interesting. From the manufacture of the burner handle. In principle, any material can be used. By the way, it would be more reasonable to simply use a ready-made handle from some old and unnecessary soldering iron. The supply tube is made exclusively of steel.

Do not forget to pay great attention to the dimensions of all parts. For example, the diameter of the burner supply tube should not exceed one centimeter, and its thickness should fluctuate around 2 - 2.5 mm. This tube is inserted into the handle and fixed with glue or other quality material suitable for the purpose.

Frame

The burner body, oddly enough, is also made of steel. It is best to use a brass rod, the width of which should be approximately 2 centimeters. The divider can also be made from it.

Next, several holes are made in order to create circulation of oxygen in the unit. After all, as anyone knows: fire cannot exist without oxygen. The total number of such holes should be four: each with a diameter of about 1 millimeter. They are made in the very core of the burner divider.

The next step is to forcefully press the divider, which was worked with a little earlier, into the body of the gas device. The inner flange must be installed with some clearance of about half a centimeter. With the help of this gap in the future, a huge flow of gas approaching the igniter will be slowed down.

Nozzle

As mentioned earlier, the nozzle is used to supply fuel, namely propane, from its cylinder to the outside. To make it you should use special metal rod. Here you will need a 2mm drill to make a blind hole in the nozzle. For the jumper we will need a 4mm drill. The holes made are caulked with a hammer, and then sharpened using everyone’s favorite sandpaper.

After this, a hose from the gearbox is mounted on the end of the tube, which must be made of special rubber and fabric material. Fastening occurs with a regular clamp using a standard screwdriver.

After the mechanism, in your opinion, is correctly secured, you need to set optimal pressure in the cylinder and supply gas from it. The air from the hose should then be completely displaced. The length of the fire, with the correct location and operation of all parts, should be about 40-50 mm.

In general, as mentioned earlier, a homemade gas burner is a rather unique tool that will come to the aid of any owner in any unpleasant everyday situations. And the maximum ease of its manufacture can only further attract all priorities to itself.
