Description

I

The invention relates to the field of fuel combustion and can be used in heat engineering power plants, metallurgy, drying equipment.

The aim of the invention is to improve the economy by reducing the underburning of fuel.

Fig. 1 shows a fuel combustion device, longitudinal section; figure 2 - section aa in figure 1.

The device for burning fuel comprises a housing 1 and a burner 2 coaxially located at its opposite ends and an inlet embrasure 3, around the perimeter of which the annular collector 4 of secondary air is placed, with nozzles 5 facing the burner 2. The cavity of the housing 1 is divided by a transverse partition 6 into two compartments 7 and 8, communicated among themselves through the central and peripheral windows 9 and 10, made in the partition 6.

The device works as follows.

Fuel with a part of air necessary for combustion is supplied to the cavity

the housing 1 through the burner 2, and the secondary air through the nozzles 5. The air mixture within the compartment 7 is ignited, which contributes to

The peripheral vortex arising in this compartment is a zone of combustion products and a secondary air heated to a high temperature, part of which passes through windows 10 in the partition 6 and is drawn into the flare. Through the window 9 of the partition 6 a mixture of fuel, air and products of combustion enters the compartment 8, in which the fuel burns in a direct-vortex flare. Due to the partition 6, part of the secondary air, when struck against it, moves in the radial direction and penetrates into the axial layers of the torch. This provides in the compartment 8 intensive mixing and good burning out of fuel not only in the vortex peripheral part of the flare, but also in its axial strand part.

Thus, the described device makes it possible to increase the efficiency of the combustion process by increasing the completeness of fuel burnout in the straight part of the flare.
