Abstract
A mechanical arrangement to reduce drastically the energy consumption for pumping condensate to feed high pressure vapor generators for power generation, industrial processing, and heating systems. Involved is a method to pump the condensate into one condensate receiver located at the sucton side of the condensate feed pump, and to bleed high pressure vapor from the vapor generator into the condensate receiver for imposing a pressure head upon the condensate therein to be approximately the same as that in the generator, and thus the pressure difference between the suction side and the discharge side of the pump is also drastically reduced while pumping the condensate into the generator, with the result that the energy consumption of the pump is also drastically reduced. The receiver is full of high pressure vapor while the condensate therein is drained by the pump, and the high pressure vapor means energy. Further new methods are involved to reduce the vapor pressure in the receiver by returning the vapor to the system or to utilize it for other purposes, as disclosed in the application. Generally speaking, at least two closed receivers operated in series are required for the metho…
