Zusammenfassung:	PURPOSE:To simply and inexpensively start a pressurized fluidized bed combined power generating plant by supplying the steam generated from a starting auxiliary boiler to a steam turbine for turning its driving shaft at the start of a generator, and by supplying the air produced with the rotation of the driving shaft from an air compressor to a pressurized fluidized bed boiler. CONSTITUTION:At the time of starting of a plant, a station service boiler 48 as a starting auxiliary boiler is started, and the steam generated is supplied to a steam turbine 18 through a pipeline 46 for turning a driving shaft 12. By the rotation of the driving shaft 12, a gas-turbine air compressor 14 coaxially connected thereto is driven, and compressed air is supplied to a pressurized fluidized bed boiler 26. Thereafter, in the process the evaporation of the pressurized fluidized bed boiler 26 is increased, the steam quantity being generated by the station service boiler 48 is decreased, and the steam generated by the pressurized fluidized bed boiler 26 is supplied to the steam turbine 18 through a pipeline 36 for turning the driving shaft 12. Thereby, a generator 22 coaxially connected to the driving shaft 12 is driven, so that starting is completed.
