(54) DEVICE FOR LIQUID FUEL BURNING

I

The invention relates to a fuel combustion technique and can be used, in particular, when heating non-contaminated materials and products.

Closest to the present invention is a device for burning liquid fuel containing a combustion chamber with a burner installed at its end and an inverted open end to the latter with a hollow reflector forming a peripheral gap | 1 with the side wall of the chamber.

The disadvantage of the known device is low reliability due to zakokso-. vyvani reflector when burning heavy liquid fuels.,

The purpose of the invention is to increase reliability by reducing coking when burning heavy liquid fuels.

This goal is achieved by having a secondary air nozzle at the bottom of the hollow reflector.

The elimination of coking due to the counter-flow of air makes it possible to burn fuel oil in the present device, a widely used heavy fuel oil.

The drawing shows the proposed device, the cut.

The device comprises a combustion chamber 1 with a burner 2 installed at its end and an open end facing the latter is hollow. the reflector 3 forming with the side wall 4 of the chamber 1 a peripheral gap 5.

In the bottom 6 of the hollow reflector 3, a nozzle 7 is provided for supplying secondary air.

The device works as follows.

to

The fuel and the main air are supplied through the burner 2. The burning flow moves in the axial part from the burner to the bottom 6, then along the inner longitudinal walls of the reflector 3 in the opposite direction and then, from the end, in the gap 5 between the reflector 3 and the combustion chamber 1 again into initial direction. The largest fuel oil droplets, concentrated in the axial part of the flow, are reflected from the 6 by a stream of additional air from the nozzle 7. This prevents the fuel oil from settling on the bottom 6 and thereby eliminates coking. In addition, the counter-stream of additional air also de- fines the mixing of combustible materials with an oxidizing agent in the reflector 3, further contributing to the complete combustion.

Elimination of underburning. It has an obvious self-worth as a means of fuel economy. A number of materials and products heated in a variety of industrial furnaces do not allow contamination with unburned fuel particles. A similar problem occurs when heating air heaters and other heat exchangers. In such cases, the proposed device can be implemented with a significant effect. The real eco-comfort effect depends on the construction of the material.

Improving the completeness of the burned (eliminating) | not underburning) allows the use of materials nc | (Non-contaminated oil in private dam of unburned fuel. In this case, additional savings are provided for an even higher quality (purity) of the products produced.

The elimination of underburning in itself, regardless of the type of fuel, has a very economical value as a fuel saving method.
