Abstract

The present invention relates to a cooling tower for the cooling water that drains from the condensor of a steam generator or from the condensors of a plurality of steam generators; the tower is fitted with large-area inserts and these form a heat-exchange area into which the cooling water is passed; a rising flow of air passes through this zone in counterflow to the cooling water, the cooling tower being provided with a smoke-gas feed to introduce cleaned, preferably wet-cleaned, smoke gas into the flow of cooling air, which is connected to a plurality of gas outlet pipes, the outlet cross-sections of which open out into the cooling tower above the heat-exchange zone. In order to improve the introduction of the cleaned smoke gases into the flow of cooling air within a cooling tower, the present invention proposes that rotors be provided in the gas outlet pipes in the area of their outlet cross-sections. To this end, it is also possible to make each gas outlet pipe rotatable about its longitudinal axis, the angle of inclination of the gas outlet pipes being variable.
