Berman, P A

A reheat pressurized fluidized bed combustor system for an electric power plant includes an HP turbine which drives a compressor. Compressed clean air is directed through a combustor bed heat exchanger where it is heated to 1500/sup 0/ F. and then directed to the HP turbine inlet. After HP turbine expansion, the clean exhaust air is cooled to about 1100/sup 0/ F. and partly directed to the combustor bed for reheating and for bed fluidization and combustor support and partly bypassed around the combustor bed. Coal is burned in the combustor bed to heat the combustor outlet gases to 1600/sup 0/ F. which are directed to a cleanup system and then mixed with the bypass flow portion. The mixed flow is supplied to a low pressure turbine at a turbine inlet temperature of 1300/sup 0/ F. at which alkali matter is solidified and then exhausted to one or more heat recovery devices.
