    • PROBLEM TO BE SOLVED: To provide 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 achieves 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.SOLUTION: 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, and furthermore 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 enabling reduction of the lengths of the flow paths of the heat sources on the fluid sides to the minimum necessary, simplify the shapes of the flow paths, suppress pressure loss therein, and achieve improvement in efficiency by a multistage configuration.
    • 要解决的问题:提供一种蒸汽动力循环系统,其有效地利用来自使用多种蒸汽动力循环的热源的热量,每个级别的蒸汽动力循环使用纯物质作为工作流体,并且实现作为热源的流体之间的有效的热交换 以及通过减少在各个热交换器中用作热源的流体的流动路径中的压力损失的工作流体。 解决方案:在蒸发器11,21和各个蒸汽动力循环单元10,20的冷凝器13,23中作为热源的流动路径分别以蒸汽功率循环之间的预定顺序串联连接 单元10,20,此外,各个蒸发器和冷凝器用作横流式热交换器并且布置在用作热源的流体流动的方向上。 因此,在构成蒸发器和冷凝器的每个热交换器中,每个流体的流入/流出方向及其在热交换器中的流动方向都与排列方向相同,从而能够缩短流路的长度 的流体侧的热源至少必需,简化流路的形状,抑制其中的压力损失,并且通过多级配置实现效率的提高。 版权所有(C)2013,JPO&INPIT
