Heat gun on waste oil

If you own a private economy, then you probably have repeatedly raised the issue of the need for heating of the dwelling and ancillary facilities by the type of garages and workshops. For this purpose, different fan heaters are usually used, however, it is not necessary to acquire such a heater, instead you can use a heat gun, which you can do by yourself.

Description of the gun on the working

The heat gun on the waste oil is structurally little different from the gas variety. It has a burner, which is designed to work with liquid fuels. There is also a fan in the design for air injection. Instead of a gas valve, in this case a fuel pump is installed, it is responsible for pumping fuel from the tank, which is located under the hull. This is the main difference.

According to the principle of gas heaters, the equipment on the working can have one of two versions, the first assumes the use of a straight line, while the second assumes the use of indirect heating. Before you can make a heat gun on waste oil, you must take into account that the combustion products of mining are much more toxic than natural gas.

This indicates that even in a well-ventilated room such a heater will in a short time create unfavorable conditions. If the device is equipped with a separate gas outlet and a branch pipe for flue gases, then the gun can be used everywhere. In order to ensure mobility, it is necessary to strengthen the frame with the wheels to the body.

The construction of the heat gun on the working

If you collect the heat gun on the waste oil, then you should become more familiar with what constitutes such a structure and how it works. The lower part is a fuel tank. The device is placed on top, in it there is a connection between the fan and the combustion chamber. The latter will be supplied with fuel, while the fan will pump hot air into the room.

For ignition and transportation of the workpiece, it is necessary to use:

• Connecting tube;
• An injector;
• filter;
• fuel pump.

The motor should be fixed to the fan. In the central part of the body it is necessary to fix the combustion chamber. It will look like a metal cylinder, the diameter of which is 2 times smaller than the diameter of the body. During combustion, the combustion products will be discharged through the tube from the chamber. In order to warm the room area of 600 m ² , you need about 10 liters of fuel.

Assembling

If you collect a heat gun on the waste oil, then its lower shell should be placed 15 cm from the top. To ensure that the oil tank does not overheat, it must be made of a material that has a low thermal conductivity. To do this, you need to use a metal tank, which is covered with thermal insulation material. Using thick metal, you can make the upper case, for this you should use a steel pipe.

Methods of work

When the heat gun on the waste oil is collected by hand, the body should be fixed:

• Fan with electric motor;
• Pump with injector;
• Combustion chamber with vertical outlet.

At the next stage, the fuel pump is installed, whereas from the tank it is necessary to remove the pipe through which the working will be fed to the fuel filter and then to the injector. The upper body of the ends should be covered with nets. The fact that the fan is powered by electricity, you need to think separately. If there is no network access, then you can use the battery.

It is important to remember that a homemade heat gun on waste oil is a source of increased danger, therefore, it is necessary to adhere to safety rules. Even if you move away from the hull to a meter, then there the hot air flow can have a temperature of 300 ° C. That's why this device is not recommended for use in closed rooms, because combustion products can be dangerous.

Recommendations of the assembly specialist

The heat gun on the waste oil, the photo of which is presented in the article, has combustion chambers, which is made of a pipe. It should be chosen taking into account the thickness of the walls, this parameter should be impressive. The combustion chamber must be provided with a hole for the injector, which will be located on one side. At the top, you need to locate the chimney connector.

It is important to purchase or find a fan with an impeller. This device will be responsible for the direction of the air flow. At assembly it is necessary to follow the certain algorithm. On one side of the enclosure, a fan should be installed, its performance must be sufficient for efficient operation. The combustion chamber should be located in the center, it is in the casing. At the end of the nozzle.

The chamber of combustion can be a galvanized pipe, the main thing is to find the product of the desired diameter. On both sides it is sealed, and at the next stage, technological holes for the chimney and injectors are made in it. It is necessary to install a piezo spark into the combustion chamber. To do this, it is recommended to stock up the product, which you can buy in specialized stores.

The heat gun on the waste oil, the description of which was supplied above, should have a fuel tank. As it is better to take finished products of the right size. In space, a fuel pump and fine fuel filter are fixed. The pump and the nozzle are connected in the next stage, and a filter is used in addition to the fuel.

Conclusion

The fan is connected through the mains dimmer, but you can do without this device, but it allows you to adjust the air temperature by the intensity of rotation of the blades. At the same time, fuel consumption will not be increased.
