Do-it-yourself burner for working out: manufacturing features and unit design
Already several decades ago, in dachas and in utility rooms, one could find burners running on waste oil.
The reasons for the popularity of the units are clear - they did not just work on "junk" fuel, but even helped with the disposal of accumulated waste.
Its design was developed by the masters on the basis of kerogas. And in our time, the device has not lost its relevance. Let's figure out how to make a burner for working out with your own hands.
Advantages:
- Relatively cheap or even free fuel.
- Ability to make your own.
- The construction is inexpensive.
- "Digests" even the most low-quality oil.
Flaws:
- Any type of burner cannot be used in a residential area (it will definitely burn and smell of oil).
- The process of making a burner is not so simple.
Device diagram and drawings
Below is a working out burner, which you can do with your own hands, having the simplest device. It can be used to study the principle of oil combustion and create more complex designs.
In general, the unit consists of:
- burners;
- fuel tank;
- dampers for adjusting the air supply;
- cock for adjusting the oil supply;
- fan or vacuum cleaner.

Do-it-yourself waste oil burner - manufacturing features
The easiest way to make a burner is using a small gas bottle or blowtorch. To work, you need to prepare:
- the above capacity;
- welding machine;
- grinder;
- a piece of 1.5-inch pipe;
- a round plate equal to the inner diameter of the pipe;
- a piece of wire 6 - 8 mm;
- a bolt with a through internal hole for the oil supply nozzle;
- thick round blank for the lid.
Beginning of work
- Two holes are drilled tangentially in the cylinder: from the bottom (for the entry of a mixture of air and oil), and from the top for the exit of the flame. Welded pipes with a diameter of 1.5 inches. One is a continuation of the other, only a little higher; so that the fire swirls inside, and does not immediately fly out into the street.
- A hatch is made on top for ignition and is equipped with a heavy lid so that during operation it does not open with the pressure of incoming air.
Waste oil is a cheap fuel and for some types of premises it makes sense to install waste oil stoves. , pros and cons of using.

Once upon a time, steam heating was widely used in our country? Why has it lost its relevance now? In this article, you will find the answer to this question and find out how the steam heating of a private house works.
Air flow control
The pressure and amount of air supplied for combustion is regulated by a homemade damper (it is made according to the throttle principle, as in a carburetor).
The damper is installed in the supply pipe up to the fuel injector as follows:
- A hole for the rotary axis is drilled strictly according to the diameter of the existing workpiece.
- A round plate is cut along the inner diameter of the pipe, which in the closed position can completely cover the hole.
- A rotary axis is made in the form of the letter "G" and a damper is mounted on it with small bolts.
- A hole is drilled in the supply pipe in front of the damper or a slot is cut to remove “excess” air (in case there is a lot of it for the burner).
The principle of supplying mining to the burner itself
To supply oil, a diffuser is arranged in the intake pipe immediately behind the damper. The diffuser is a turned annular insert, slightly narrowing the flow area. Thanks to him, a vacuum is created and oil (or other liquid fuel) enters through the nozzle and mixes with air.
For the supply pipeline, it is preferable to use metal pipes. A freon tank is well suited for a fuel tank, and a needle valve allows you to fine-tune the oil supply.
A simple homemade burner
Oil must be separated from water and filtered.
Principle of operation
Fuel is fed by gravity to the nozzle and is sucked in by air passing through the diffuser. The resulting mixture ignites inside the cylinder, and the torch is blown out into the street. Thus, the heat source is the burner itself (it heats up to a crimson glow) and the torch.
The flame can even be used to melt certain metals such as copper, aluminum and others that have a lower melting point.
DIY Babington burner
Another type of flare burner available to make at home is the Babington spherical burner.
Her device includes:
- tee with a diameter of two inches;
- metal tube for fuel supply;
- driving according to the thread size of the used tee;
- hollow steel ball;
- air compressor;
- metal corners;
- thick wire.

Construction scheme
The tee is the basis of the device.
- A drive is screwed into it along the thread with a 15 - 20 mm hole drilled on the side (for ignition) - we get a burner with a nozzle.
- A hole is drilled on top of the letter "T" formed by the tee for connecting a pipe supplying liquid fuel. It is wound in the form of a spiral around a nozzle heated by a flame. This is necessary to achieve the required temperature and viscosity of the oil.
- And under the outlet of the supply tube, inside the tee, a ball or hemisphere is fixed, with a calibrated hole 0.27 mm ± 0.02 mm, oriented strictly in the center of the nozzle. You can use a jet of the specified size to simplify the task.
- Air is supplied from the compressor by a pipe connected to the back of the ball.
- Excess oil is drained through the lower branch of the tee.
- The oil supply tank is fixed away from the burner (and above it) to provide the necessary pressure.
- The whole apparatus is mounted on legs, which can be made of thick wire. It must be very stable!
The device works like this. Oil is supplied to the spherical surface by gravity or by means of a pump. From inside the ball, streamlined with oil, the air pumped by the compressor comes out under pressure.
It atomizes the oil and forms a torch directed into the nozzle. This design is mounted inside the tee. Excess oil and impurities are collected in a sump located below. To avoid fire, it must be located as far as possible from the torch.
The advantage of this type of flare burner is that it is undemanding to the quality and viscosity of the oil. Since only air passes through the calibrated hole.
Conclusion
A conventional solid fuel stove can be upgraded by adding a torch burner to its design.To do this, a hole is cut out in the furnace door strictly according to the size of the nozzle.
The burner is inserted with the nozzle inside, and its flame replaces the fire from conventional fuel. When the opening is covered with a rotating "curtain", the oven can be used as usual.
This type of heating can only be arranged in stokers and utility rooms. This is especially true of the first described design (it smokes more when ignited).
