ABSTRACT:
The cooling air cooler (10) for power plants of combined operation is designed as a helix steam generator which works on the countercurrent principle and is located in a vertically arranged cylindrical pressure vessel (23) and the spirally coiled tubes (30) of which fill the space between an inner (26) and an outer (41) jacket tube, water (12) being capable of being supplied to the tubes (30) via a conduit (32) and steam (14) being capable of being discharged from the tubes (30) via a conduit (33), the evaporating water (12) flowing through the helix from the bottom upward and the cooling air (11), capable of being supplied by the compressor (1) via an inflow conduit (24), flowing through the helix from the top downward, and the air (11) experiencing deflection before reaching an outflow conduit (25) at the lowest point in the pressure vessel (23) after flowing out of the helix. When the power plant is operating normally, the steam (14) generated in the cooling air cooler (10) is guided to the steam turbine (17) via the waste-heat boiler (15). For operating situations where the gas turbine works alone, water injection into the air (11) to be cooled or a supply of the steam (14) generated in the cooler (10) into the cooled air (13) is provided.
