Condensation apparatus for steam turbine power plants

A condensation apparatus for steam turbine power plants comprising, in combination, a mixing condenser;

• a cooling system for cooling condensate withdrawn from said mixing condenser;
• first conduit means connecting said mixing condenser and said cooling system for flow of condensate from said condenser to said cooling system;
• second conduit means connecting said cooling system to said mixing condenser for flow of cooled condensate from said system to said condenser;
• first circulating pump means in one of said first and second conduits;
• said cooling system including an air-operated cooler incorporating a heat exchanger, an air supply means having an inlet passage, a liquid-operated cooler incorporating a heat exchanger, third conduit means connected for transferring condensate from said first conduit means through said air-operated cooler and said liquid-operated cooler to said second conduit means, and second circulating pump means for circulating coolant liquid from an outside source through said liquid-operated cooler;
• sensors for determining the condensate temperature and the pressure in said mixing condenser;
• an adjustable valve positioned for adjusting the flow of coolant liquid to said liquid-operated cooler;
• and control means for receiving information from said sensors and adjusting said valve for optimum flow of coolant liquid in accordance with the information received.
