Abstract: 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.

Abstract: There is provided a steam power cycle system that permits to perform an appropriate heat exchange between a working fluid that is a non-azeotropic mixture and a heat source, to enhance the performance of the whole system. More specifically, a plurality of condensers are provided so as to be connected to each other in series, and the working fluid in a gas phase from the expander is introduced into the respective condensers. Consequently, the ratio of a low boiling point substance of the working fluid becomes higher toward the posterior condenser, it is possible to make the condensation temperature of the working fluid lower than that of the anterior condenser. It is therefore possible to make the temperature of the working fluid possibly close to the temperature of the low-temperature fluid, thus permitting an effective use of the difference in temperature of the heat source.
