摘要
FIELD: boilers with fluidized beds working at supercritical pressure of steam. SUBSTANCE: boiler includes furnace chamber 14 with fluidized bed, recirculation system for recirculation of fluidized solid particles in furnace chamber and many tubes 58 designed to withstand supercritical pressure. Tubes are arranged around walls of furnace chamber 14 for recirculation of cooling fluid medium between inlet header 54 in lower portion of chamber and outlet header 56 in upper portion of furnace chamber 14. Separator 66 for separation of water from steam directs steam to steam superheater 70; under normal operating conditions, separator is bypassed. EFFECT: enhanced efficiency. 13 cl, 2 dwg
