Abstract: An apparatus for saving boiler feed water heat having a closed condensed water vessel for collecting the steam water condensate from one or more reactor steam jacket, and the steam condensate flash over when it enters the closed vessel due to pressure drop. The closed vessel having a boiler feed water pump located below the vessel and the vessel located below the reactor steam jacket, and cold water injection into the condensate prior to entering the feed water pump. The feed pump then taking the cooled condensed water to the boiler reducing the demand for boiler make up water and saving heat and energy.

Abstract: Mechanical methods for reducing drastically the energy consumption of high pressure liquid pumping.The basic method is to utilize high pressure vapor at the suction side of the pump to reduce the required pumping pressure head. The energy content of the high pressure vapor is returned or utilized. Disclosed high efficiency heat exchangers and expansion absorbing vessels are provided to reduce energy requirement for transferring liquid to a vapor generator, a high pressure apparatus and a extended pipe line.

Abstract: A system of production and distribution of condensable vapor in a close circuit, at approximately constant pressure and temperature serving two systems of stations utilizing vapor at respectively high pressure and low pressure, comprising a transfer lock arrangement, for transferring condensates from a low-pressure condensate reserve to a high-pressure condensate reserve, wherein the low-pressure condensate return line and the drain conduit connecting the two condensate reserves are respectively provided with two motor-actuated stop valves and whose servo-motors are respectively connected to the monitoring member of the level controller of the low-pressure condensate reserve.

Abstract: Mechanical methods for reducing drastically the energy consumption of high pressure liquid pumping and for eliminating the use of expensive multi-tube heat exchangers.The basic method is to utilize high pressure vapor at the suction side of the pump to reduce the required pumping pressure head. The energy content of the high pressure vapor is returned or utilized. Additional methods are provided to reduce energy requirement for transferring liquid to vapor generator, apparatus located at high elevation and apparatus having high pressure resistance.

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.
