Abstract
In a method for operating a gas turbo group, partial streams of compressed air are cooled in cooling air coolers and are used as cooling air for thermally highly stressed components of the gas turbo group. The cooling air coolers are constructed as steam generators. Steam generated in the cooling air coolers is fed in part to the gas turbo group and is expanded there while providing usable power, while another part of the steam is fed into the cooling system, where the steam displaces air, which air then becomes available again to the gas turbine process. In this way, the steam generated with the help of heat removed from the cooling air is re-used.
