Abstract
Abstract Steam turbine power plants employ condensers for condensing the dead steam withdrawing from the turbine. The condensers require cooling which is obtained by cooling water. This is, in turn, recooled by cooling towers one type of which works with surface heat exchangers cooled by air. Then, the condenser is of the mixing condenser type. Where the employment of such system is jeopardised by the hazards of climatic conditions, the surface heat exchangers of the dry cooling tower may be provided with vertical ribs. A water spray serves for besprinkling the surface heat exchangers so that a water film will run down on the vertical ribs, thereby augmenting the cooling effect of the surface heat exchangers where, otherwise, they would fail to ensure a desired low condensation temperature in the mixing condenser.
