Steam turbine 1 is a generator 2 gas It is connected to the turbine 3 via one shaft or an intermediate reduction gear. 5 and 6 are Ka showing the coupling. Exhaust gas from the gas turbine 3 is guided to an exhaust gas boiler 4 . The steam generated in the exhaust gas boiler 4 passes through the main steam stop valve 8 and the control valve 7, and then goes to the steam turbine. fed into bin 1.

The air cooling device includes an air blower 10, a stop valve 11, a check valve 9, and Release valve 12 was installed. Then, the air blower 10 is started at the same time as the combined cycle is started. Then, cooling air is supplied to the steam turbine 1 through the stop valve 11 and the check valve 9, and the air is opened to the atmosphere. By discharging from the relief valve 12, the steam turbine 1 is cooled. A while after startup Then, when steam can be supplied from the exhaust gas boiler 4, the main steam stop valve 8, The control valve 7 is opened and steam is introduced into the steam turbine 1 to be used for power generation.
