FIELD: drying of fuel used for burning in boiler with fluidized bed. SUBSTANCE: hot inert solid materials of fluidized bed are delivered at controlled flow rate from furnace 2 to standard drier 11 included in line 7 for fuel delivery to boiler 1. In result, fuel is dried and steam is produced. Due to controlled recirculation of solid materials in fluidized bed, it is possible to maintain constant temperature in drier 11 which allows for excluding all heat transfer surfaces from drier 11. Almost clean steam generated in process of drying is directed from drier 11 for useful application. EFFECT: high efficiency. 1 dwg |
