DEVICE AND METHOD FOR GRANULATED SOLID FUEL COMBUSTION Russian patent published in 2016 - IPC F23B30/04 

FIELD: energy.

SUBSTANCE: invention relates to power engineering. Device (100) for combustion of granulated solid fuel contains chamber (102), with external wall (104) and internal wall (106), dividing the internal space of said chamber into space (108) for air for combustion and combustion chamber (110), at least one air blower (112) to ensure combustion air, and means of rotation (113) for rotation of said combustion chamber. Inner surface of said combustion chamber comprises multiple steps (138) for lifting of fuel in said combustion chamber, and is provided, at least one hole (140) in at least one stage for direction of primary air in said combustion chamber in a direction substantially parallel to said combustion chamber and/or along the circle of said combustion chamber to facilitate combustion of fuel and displacement of said fuel at said stages, said combustion chamber comprises, at least one hole (204) for supply of secondary air into said combustion chamber in a direction substantially parallel to the axis of rotation of said combustion chamber to remove completely burnt fuel and, if necessary, gaseous combustion products from said combustion chamber, the rotary motion of the combustion chamber provided with said means of rotation, and said primary air together lifted fully burnt fuel in said secondary air in order to remove it from said combustion chamber.

EFFECT: invention increases completeness of fuel combustion.
