Abstract: Low-pressure-side condensate is subjected to convection heating while dripping in high-pressure-side steam, and to surface turbulent heat transfer due to a circulating flow caused by downflow condensate falling after overflowing. Thus, the temperature of the low-pressure-side condensate can be raised efficiently with satisfactory heat transfer. A bypass connecting pipe enables high-pressure-side condensate to bypass condensate of a reheat chamber and merge with the condensate while keeping a high temperature. Thus, heating of the low-pressure-side condensate is performed sufficiently, with a space for falling being minimized for compactness. Also, condensate in a high amount of heat exchange is fed toward a condensate pump. Hence, a multistage pressure condenser permitting compactness and increased efficiency of a power plant can be constructed.
