Document Type and Number:
Japanese Patent JP2624891
Kind Code:
B2
Abstract:
A pressurized fluidized-bed boiler power plant comprises: a pressurized fluidized-bed boiler (3) including a fluidized-bed boiler and a pressure vessel containing the fluidized bed; a single-shaft gas turbine including a gas turbine (2), an air compressor (1) and an electric generator (14); and a steam turbine unit (6-9) in which steam generated by the pressurized fluidized-bed boiler drives a turbine so that electricity is generated. In the power plant, an air cooler (15) is situated in a duct (16) for conveying the compressed air from the compressor (1) to the boiler (3) or at an inlet of the compressor. Alternatively, there may be provided a device for conveying the compressed air from the compressor by way of the air cooler to a space formed by the fluidized-bed boiler and the pressure vessel of the pressurized fluidized-bed boiler. During operation, the compressed air is cooled to a temperature level allowable for the pressure vessel before it is supplied to the boiler.
