Abstract
A pressurized fluidized bed combined electricity generation system for improving gas turbine output increases and prevention of surging is provided. This pressurized fluidized bed combined electricity generation system is a combined electricity generation system including a steam turbine; a pressurized fluidized bed boiler for generating steam for supply to the steam turbine by combusting air from an air supply system and fuel from a fuel supply system; a gas turbine driven by exhaust gas such as combustion gas from the pressurized fluidized bed boiler and the air; and a compressor directly coupled to the gas turbine. In addition, this pressurized fluidized bed combined electricity generation system has a first bypass duct communicating between the outlet side of the compressor and the exhaust gas side of the gas turbine and having a switching valve; a second bypass duct communicating between the outlet side of the compressor and the inlet side of the gas turbine and having a switching valve; and a control device which receives measured pressure values of a pressure detector which measures the pressure at the outlet of the compressor. This control device controls the switching valv…
