PLANT FOR SOLID FUEL BURNING Russian patent published in 2008 - IPC F23B60/02 F23B10/00 

FIELD: heating.

SUBSTANCE: plant for solid fuel burning contains furnace extension and vertical furnace, which are connected via outlet screen. In furnace extension horizontal air distribution grid is installed, where fuel is exposed to partial combustion in "burning layer" of inertial material, pilot burner and device for fuel supply. In the top part of outlet screen two nozzles of secondary blowing are installed, which are directed to the bottom part of furnace. The outlet screen is formed by pipes of front screen, which is bent to the side of furnace back screen, which forms a sloping bottom with this screen and side screens. The section of front screen, which is installed above the bent part of outlet screen, is bent to the side of the furnace back screen. In the furnace extension horizontal air distribution grid is installed, on which a layer of inert material is placed, at least, one pilot burner and device for fuel supply, at that, at least, two nozzles of secondary blowing are installed in the top part of outlet screen and are directed to the bottom part of the furnace, in which bottom blowing device is installed.

EFFECT: increase of fuel burning efficiency by means of better mixing of secondary blowing air with products of fuel gasification.
