Description

This invention relates to fuel combustion and can be used on thermal power tools.

The aim of the invention is to improve the economy.

FIG. 1 shows a furnace, a longitudinal section - (option 1), in FIG. 2 shows section A-A in FIG. 1j in FIG. 3 - a firebox, longitudinal section (option 2).

The furnace contains a vertical prismatic combustion chamber 1 with burners 2 placed in rows on its horizontal, wall 3, and nozzles 4 placed in rows on two side opposite walls 5 with displacements of their rows relative to rows of burners 2. Nozzles A- installed in staggered order with the placement of each pair of opposing nozzles 4 on different sides of the corresponding row of burners 2 and at a distance from the horizontal wall 3 equal to 2.5-6 equivalent diameter of the nozzles 4.

The burner 2 can be filled with vortex, and the nozzle 4 - slot.

The furnace works as follows.

A portion of the air required for combustion and fuel is supplied through the burners 2, and the rest of the air is introduced into the volume of the combustion chamber 1 through nozzles 4. The air-fuel mixture flows from the burners 2 are heated by the suction of hot combustion products from the environment and also radiation from the torch and ignite. As they develop, vertical factories interact with transverse air flows and nozzles 4, which penetrate the space of the combustion chamber 1, forming around the torches a group of burners 2 along with air circulation. As a result of such air circulation, the latter is drawn into vertical flares and mixes well with the fuel. Intensification of air mixing with fuel helps, in addition, twisting the flares of each group of burners 2 in the direction of air circulation. By making the nozzles 4 slotted with vertical embrasures, the horizontal flows moving in the direction of the walls 5 of the combustion chamber 1 penetrate to a greater depth of the latter without demolition in the vertical plane. In this furnace, active re-exchanging of the fuel with air is also carried out in the area where the air flows turn in a vertical plane, which also intensifies the burning out of fuel in the afterburning zone of the torch.
