To improve the thermal efficiency and environmental characteristics of coal-fired power-generation systems, The Chugoku Electric Power Co., Inc. and the Hitachi Group developed the first commercial 250-MW PFBC (pressurized fluidized bed combustion) combined-cycle power plant in Osaki. The Osaki PFBC plant was commissioned, and its commercial operation began on Nov. 30, 2000. We will describe the main features of the equipment and several trial-operation results of the Osaki PFBC plant. The plant has a combined-cycle arrangement with the gas turbine and steam turbine producing an output of approximately 15 and 85%, respectively, of the total electricity. It also has a pressurized-fluidized-bed-combustion boiler, which generates steam to drive the steam turbine. The gas from the boiler is directed to a two-stage multi-cyclone, which drives the gas turbine. The boiler consists of two vessels with two furnaces.
