Abstract
In a combined power station installation with a gas turbine (4) and a steam turbine (9-11), the exhaust gases from the gas turbine give up their residual heat to the steam turbine via the working medium flowing in a waste heat boiler (7). The waste heat boiler consists essentially of an economizer (21), an evaporator (22) and a superheater (23). A cooling air cooler (32, 33) designed as a once-through steam generator is connected on the water side to the economizer (21) of the waste heat boiler (7). The waste heat boiler is a once-through steam generator in which a separation bottle (25) is arranged on the steam side between the evaporator (22) and the superheater (23). The cooling air cooler (32, 33) is connected on the steam side to the separation bottle (25).
