Summary: | In a combined cycle system including a gas turbine (12), a steam turbine (20) and a heat recovery steam generator (32), wherein gas turbine exhaust is used in the heat recovery steam generator (32) for reheating steam for the steam turbine (20), an improvement wherein steam is extracted from the heat recovery steam generator (32) at a location where steam pressure is highest, conducted to the gas turbine (12) for cooling hot gas turbine parts, and returned to the steam turbine (20) at the point of highest pressure admission. |
