FIELD: combustion apparatus. ^ SUBSTANCE: vortex furnace comprises combustion chamber, which has walls made of a hopper in their bottom part, at least one burner embedded into the wall, and nozzle device for supplying air to the furnace mounted at the bottom section of the hopper. The nozzle device has two nozzles. The first nozzle points to the inner surface of the hopper mounted from the side of the burner at an angle of The second nozzle is oriented so that the angle between the longitudinal axes of both of the nozzles is in the plane perpendicular to the inner side of the hopper from the side of the burner. At least one nozzle can be sectioned. The nozzles can be provided with flow rate controllers. ^ EFFECT: enhanced reliability and efficiency of the furnace. ^ 2 cl, 2 dwg |
