Abstract
Steam turbine power plants employ condensers for condensing the dead steam of the turbine. The required cooling in the condenser is obtained by cooling water which is, in case of dry cooling towers, injected into a mixing condenser. Recooling of the cooling water is obtained in surface heat exchangers of the dry cooling tower which carry off the heat by means of air. Where the employment of such system is jeopardised by the hazards of climatic conditions, it is suggested to associate water cooled heat exchangers with the surface heat exchangers and the dry cooling tower of the system. Such water cooled heat exchangers serve as auxiliary means where the cooling effect of the surface heat exchangers of the dry cooling tower fails to ensure a desired low condensation temperature in the mixing condenser.
