Abstract: Steam power plants utilize high pressure and low pressure feedwater heaters to increase overall system efficiency. Both types of feedwater heaters generally include a subcooling zone that is separate from a condensing zone. The viability of the separation of the zones is critical to the efficiency of the overall system, specifically with regard to the inefficiencies inherent in the leakage of steam from the condensing zone into the subcooling zone. An improvement in the viability of that zone separation for such feedwater heaters is taught by the use of dual end plates for the subcooling zone to create a triple layer of separation between the condensing and subcooling zones to prevent unwanted and inefficient steam leakage.

Abstract: A freeze resistant method for draining liquid condensate from a condensate furnace includes quickly purging the liquid condensate from a condensate reservoir. A condensing heat exchanger connected to a condensing reservoir stores liquid condensate as the system is in use. An inducer produces a positive pressure along a condensate line to the outlet of the reservoir, creating a back pressure which prevents draining of the reservoir. When the inducer is shut off, the positive pressure is removed, and the liquid condensate rapidly flushes from the reservoir. The amount of liquid condensate remaining in the system and exposed to cold conditions can be minimized.
