Abstract
A combined cycle power plant is disclosed, whose target high-temperature portion in the gas turbine can be reliably and sufficiently cooled, and in which the heat generated via the cooling can be reliably recovered, thereby improving the efficiency. Here, the exhaust gas from the high-pressure turbine is introduced as cool steam to the steam cooling system for cooling the target high-temperature portion in the gas turbine. This cooling process is efficiently and suitably performed by using the characteristic of the above high-pressure exhaust gas relating to quantity, pressure, or temperature.
