BOILER FOR BURNING COAL, CRUSHED MUNICIPAL WASTE AND METHOD OF ITS OPERATION Russian patent published in 2022 - IPC F23C10/10 F23B101/00 F23G5/30 

FIELD: boiler building.

SUBSTANCE: invention relates to the field of boiler building and is intended for burning solid fuel - coal and crushed solid municipal waste in a fluidized bed. The boiler unit for burning coal and crushed solid municipal waste in a fluidized bed consists of a mechanical combustion device in the form of a movable grate inclined to the horizon with air supply under the grate and in the above-layer space, heating surfaces in the form of gas-tight screens that provide a turn of gases to organize an entrainment return system , ejector, air duct in the primary blast zone under the grate bent to a vertical position, an air duct in the secondary blast zones made in the form of slotted nozzles; The feeder is made elongated and above its elongated part in the direction of fuel supply behind the bunker for coal mixture there is an additional bunker for crushed solid municipal waste, at the same time, under the feeder auger in the area of ​​the coal bunker, the lower semicircle of the screw feeder trough is made with longitudinal slotted holes and equipped with a conical tray, the lower part of which is connected by an inclined downward pipeline to a pneumatic caster into the furnace of the boiler unit, and two burners are installed in the side lining of the boiler towards each other. devices.

EFFECT: invention provides the possibility of burning in a low-power boiler unit with a fluidized bed of coal with a crushed sorted mixture of particles of municipal solid waste, as well as increasing the efficiency of coal combustion both independently and together with waste.
