ABSTRACT:
A combined circulation condenser for a steam cycle apparatus is disclosed. The steam cycle apparatus includes a steam generator with a port for receiving a fluid. The steam generator presents heat to the fluid to generate steam that is directed out another port, which presents the steam to a turbine to generate electrical power. The turbine has an outlet that directs an exhaust steam into a condenser. A fluid flow system is inside the condenser, which directs cooling water along a pathway through the condenser so that the cooling water cools the exhaust steam, forming condensate. A condensate pump collects and pumps the condensate along another pathway through the condenser so that the condensate can additionally cool the exhaust steam. Simultaneously, the exhaust steam warms the condensate. This pathway directs the condensate to a feed pump, which pumps the condensate back to the steam generator through the generator's input port.
