This design, combined with a separate ejector system for each tube row, ensures maximum reliability. Condensed steam from the rear headers is collected in Hudson's patented condensate recovery system. The design maintains high efficiency over a wide temperature range and partial load operation while minimizing the potential for freeze-up . The fans are available in diameters ranging from 5 to 60 feet. A typical flow diagram of a turbine exhaust steam air-cooled condenser system is illustrated below.
Steam enters the condenser at the higher end of each bundle and condensate flow out the lower end.
Non-condensables are removed from each row by means of individual steam jet air ejectors or vacuum pumps. Condensate flows by gravity through the patented drain system to the conensate tank. Optionally, condensate can be reheated in a deaerator utilizing steam from the turbine exhaust. This flow diagram illustrates an A-frame configuration. Stac-Flo steam condensers are also available in horizontal and vertical configurations.
