摘要： A coal gasification composite power generating plant has a coal gasification plant and a composite power generating plant. The coal gasification plant has a low-pressure steam generator for recovering heat from the furnace wall of a pressurized fluidized bed type coal gasification furnace, and a high-pressure steam generator disposed at the outlet of the gasification furnace and adapted to recover heat from the unrefined gas coming from the gasification furnace. The composite power generating plant includes a gas turbine which uses the gas generated in the gasification plant as the fuel gas, a boiler for recovering heat from the exhaust gas of the gas turbine, and high-pressure and low-pressure steam turbines which operate with the steam generated by the boiler. The high-pressure steam generated in the high-pressure steam generator is introduced to the high-pressure steam turbine, while the steam generated in the low-pressure steam generator is introduced into the low-pressure steam turbine, thereby to effectively recover the energy.
