Abstract
A loss of heat that can be recovered in a heat recovery steam generator is eliminated, whereby a combined cycle electric power generation plant with high heat recovery efficiency is provided. A combined cycle electric power generation plant is adopted that includes a heat recovery steam generatorthat generates steam for driving a steam turbineusing heat of exhaust gas of a gas turbine, a cooling air coolerthat causes high-pressure feed water supplied from a low-pressure economizerof the heat recovery steam generatorand compressed air for turbine cooling extracted from a compressorof the gas turbineto perform heat exchange to heat the high-pressure feed water to thereby cool the compressed air, and a fuel gas heaterthat causes the compressed air cooled in the cooling air coolerand a fuel gas of the gas turbineto perform heat exchange to further cool the compressed air to thereby heat the fuel gas.
