Burner for working: drawings. How to make a burner for work

The idea, which involves the use of waste oil as an active energy carrier for heating, is not new. In view of the fact that there is a lot of testing at the car maintenance stations, a problem arose in the need for disposal. This particularly applies to stations that specialize in the maintenance of trucks. It is no wonder that articles of factory and artisan production began to appear, which allow burning of the mentioned substance, receiving thermal energy. One of these devices is a burner for working.

Design features

You can create this device yourself. Ensure the efficient burning of old oils is not easy, due to the fact that the work from any car service represents a mixture of oils of different viscosities with different amounts of impurities. In small doses, it contains antifreeze, diesel and gasoline. All these moments are taken into account in the designs of burners, which were made in the conditions of the plant. They have special filter elements. If we consider the Babington burner, then it does not presuppose the presence of filtering. This is due to the fact that the fuel in this construction flows down a spherical surface, forming a film. In the central part of this sphere there is a small hole, the diameter of which is 0.1-0.3 millimeters. This part is necessary for the supply of air under pressure. Such a burner works on the principle of piercing through the opening of air, which cuts off part of the oil that flows down the surface. As a result, it is possible to get a torch, which consists of a fuel-air mixture, capable of ignition.

Absence of filtering

The amount of dirt in the oil can only affect the efficiency of combustion, the design while working on the working, not clogged by suspended impurities. It is for this purpose that the burner on the working is not provided with holes of small diameter. The hole in this device is only one - through it passes the air. Instead of a rather complicated filtration system, the burner provides for the supply of oil to the spherical surface, and the excess flows down to the settler.

Ensuring quality combustion of oil

In order for the described burner to work as efficiently as possible, burning oil, it is necessary to preheat the fuel. This is required for two reasons, as the first of them is the fact that the substance acquires the ability to well envelop the base of the sphere. As a result, the air supply contributes to a better distribution, forming a good aerosol torch. The need for heating is also in reducing the flash point. When using heated fuel, it is much easier to provide an ignition for the device, and the operation takes place with the maximum use of energy of the oil, which generates more heat.

The difference between the Babington burner and the blowtorch

Quite often the burners, which work on the principle of supercharging, are compared with a blowtorch. Their devices have some similarities. Then the principle of action is different. In a blowtorch, fuel, namely gasoline, is in a closed container. It is exposed to high air pressure, which is provided by using a hand pump. The air is not mixed with fuel, the latter is pushed upward. Along the way, gasoline warms up, gradually evaporating in the pipe. After that, it is injected into the jet nozzle. After leaving it, gasoline mixes with air, burns and forms a powerful torch. The homemade burner operates on the reverse principle. The air is blown through the nozzle, not the oil. The fuel does not evaporate, but is heated to a temperature of 70 degrees, but no more.

The liquid does not flare up completely, some volume goes to the sump. A homemade burner can not be produced from a blowtorch, since it is very difficult to evaporate and feed the oil through the nozzle into the combustion zone. It should be taken into account before making such a design that it is inefficient and dangerous to fill the described unit with gasoline.

Manufacturing technology

Due to simplicity and prevalence, a burner designed for a waste oil boiler is made by specialists and home masters in a variety of variations. At the first stage you will have to pick up all the necessary materials and tools, among them a metal tee, which is equipped with an internal thread of 50 millimeters. This element will be needed to make the case. Useful and the drive, which has an external 50-millimeter thread. This component will form the basis of the nozzle. The length can be chosen at will, however this parameter should not make a figure less than 100 millimeters. If you are going to make an evaporative burner for working, it is important to stock up with a knee made of metal DU-10. The workpiece must have an external thread in the amount of 2 pieces, which will be needed to connect the fuel line. Prepare a copper tube DU-10 of the necessary length, which will go to the fuel main. The length should not be less than one meter. A hemisphere or a steel ball that will fit freely into the tee will be needed for the working part. The metal tube DU-10 will be needed to connect the air path.

Methods of work

If you perform an evaporation burner on the run, it will be necessary to perform one fairly accurate manipulation, which consists in making a hole in the central part of the sphere. Its diameter should be a limit of 0.1 to 0.4 millimeters. As the best option, the figure is equal to 0.25 millimeters. You can do this using one of two methods. The first involves reaming with the right diameter tool. If you decide to use the second method, you will need to install a ready 0.25 mm jet.

Council of the master

It is important to remember that the holes should be located strictly in the central part, while the axis should be parallel to the walls of the housing, or rather the tee. In the latter, the sphere will be mounted. The deviation may be the lowest, otherwise the torch will be directed to the side, which will negatively affect the stable operation and excessive fuel consumption. Experienced masters often face the complexity, which is due to the fact that a small hole is very difficult to do. Thin drills will break.

Features of the hole

If you need a burner for working, you can prepare the drawings yourself before the time of manufacture. In order to make a calibrated hole, you need to put a jet of the required diameter into the spherical part of the autonomous structure. To do this, a hole is made, the diameter of which should be less than the outer diameter of the nozzle. After that, the processing is performed by sweep. At the final stage, the jet is pressed inside, and then thoroughly polished. If it is necessary to manufacture a burner of impressive power, the diameter of the nozzle should be increased to a limit of 0.5 millimeters. As an alternative, you can drill two small holes, observing between them a step of 7 millimeters or more. As soon as this operation is completed, the burner on the working for the boiler can be assembled.

Methods of work

If you are thinking about how to make a burner on the workpiece, you need to make a hole on the side of the nozzle, which should be wide enough to lightly ignite the device. The oil heating spiral should not be excessively large, only about 3 turns will be enough. Finished products are fixed on the mounting plate, and then built into any boiler, which can be made and homemade. After completing the work, it is necessary to connect the fuel and air line, and then supply air and oil.

If a burner is produced on the cutting torch, then the simplest method of fuel supply is self-draining, for which the waste oil container must be fixed to the wall, arranged so that the element is above the burner device. A tube is laid from the container. When a burner is used for working out of a spray gun, a pump is used to pump the oil in this case. In this case, even monitoring sensors and a control unit can be used later. This technology allows you to get a burner that operates in an automatic mode. The use of such a device is as safe as possible.

Recommendations on fuel consumption

If you decide to transfer the diesel burner to mining, you can eventually achieve fuel consumption that does not exceed 1 liter per hour. At the same time, the work needs to be done observing the technology. The diameter of the air hole in this case should be equal to 0.25 millimeters. With the functioning of black soot should not form, in addition, it will be possible to achieve a uniform burning of the torch. If necessary, the settings will need to move the sphere backward or forward. You can achieve correction by changing the air pressure. With the issue of injection is able to cope with any compressor, you can use even one that was borrowed from the refrigerator. This is due to the fact that the operating pressure does not exceed 4 bar.

Conclusion

The burner described in the article is an excellent solution for those who are able to buy old car oil for a pittance or not at all cheap. With certain skills, it is possible to integrate this device into the combustion chamber, which has a water jacket and a chimney. This will make it possible to obtain an efficient waste oil boiler.
