FIELD: drying fuel used for boilers with fluidized bed. SUBSTANCE: hot inert solid materials of fluidized bed of boiler 1 are directed at adjustable intensity from furnace 2 to drier 11 connected in line 7 feeding fuel to boiler 1, thus providing for drying fuel and forming vapor. Temperature of drier 11 may be kept at constant level due to control of recirculation of solid materials of bed, thus making it possible to avoid heat-transfer surfaces in drier 11. Pure vapor formed in course of drying is directed from drier 11 for use. EFFECT: enhanced efficiency. 11 cl, 2 dwg
