Abstract

See full text

There is provided a steam power cycle system in which steam power cycles using pure materials as a working fluid is used in a multiple stage to reduce pressure loss in the flow channels in the respective heat exchanger so that the fluid serving as heat sources has been caused to make an effective heat exchange with the working fluid. More specifically, not only that the respective flow channels for the fluid serving as heat sources in the evaporator and the condenser in the respective steam power cycle units are connected in series to each other, but the evaporator and the condenser comprise a cross-flow type heat exchanger and are arranged respectively in a flowing direction of the fluid serving as heat source. Consequently, it is possible to reduce the length of the flow channels to the minimum necessary, simplify the flow channel structure, and reduce the pressure loss.
