This paper describes the conceptual design of an advanced technology coal gasification combined cycle power plant which has significant advantages over other power generation technologies. The plant is expected to provide lower capital and operating costs and superior environmental acceptability than other modes of generation.
The design is based on the KRW Energy Systems Inc.’s pressurized fluidized bed coal gasification system. Hot cleaning of the fuel gas is accomplished using concepts being developed at the Waltz Mill pilot plant. Desulfurization of the fuel gas is by injection of dolomite into the gasifier bed. Final particulate removal is accomplished by an external filter. Net power output from the plant is 73 MW and the overall plant heat rate is 8760 Btu/KWh (HHV).
