Abstract:
A combined cycle power plant comprising:a gas turbine portion including(i) a low pressure compressor to compress air supplied thereto,(ii) an intermediate cooling device to cool compressed air that is discharged from said low pressure compressor, and also to generate steam from water supplied to the intermediate cooling device,(iii) a high pressure compressor to compress the compressed air discharged from said intermediate cooling device,(iv) a combustion device to burn fuel along with the compressed air discharged from said high pressure compressor such that a combustion gas is generated, and(v) a gas turbine to be driven by the combustion gas generated by said combustion device; andan exhaust gas heat recovery portion including(i) a steam generating device to recover heat from an exhaust gas discharged from said gas turbine, and use this recovered heat to generate steam,(ii) a steam turbine to be driven by the steam generated by said steam generating device, and(ii) a condenser to condense an exhaust vapor gas discharged from said steam turbine into water.
