|Title||STEAM POWER CYCLE SYSTEM|
The present invention is a steam power cycle system which effectively utilizes heat from heat sources using multiple stages of steam power cycles each using a pure substance as a working fluid, and enables efficient heat exchange between fluids serving as heat sources and the working fluid by reducing pressure loss in the flow paths of the fluids serving as the heat sources in respective heat exchangers. More specifically, not only respective flow paths of fluids serving as heat sources in evaporators (11, 21) and condensers (13, 23) of respective steam power cycle units (10, 20) provided in multiple stages are connected in series in a predetermined order between the steam power cycle units (10, 20), but also the respective evaporators and condensers are used as crossflow heat exchangers and arranged in directions in which the fluids serving as the heat sources flow. Consequently, in each of the heat exchangers constituting the evaporators and condensers, the inflow/outflow direction of each fluid and the flow direction thereof in the heat exchanger are all the same as the arrangement direction, thereby making it possible to reduce the lengths of the flow paths of the fluids serving as the heat sources to the minimum necessary, simplify the shapes of the flow paths, suppress pressure loss therein, and achieve improvement in efficiency by a multistage configuration.
