It can be seen in this case,that unlike steam,starting from saturated vapour,the working fluid becomes
superheated as it expands.Therefore,there are no blade erosion problems associated with its use.In
order to improve the cycle efficiency,at the end of expansion,the low-pressure superheated vapour can
be passed through a counterflow heat exchanger,or recuperator,to recover the heat that would otherwise
be rejected in the condenser and use it to preheat the pressurized liquid leaving the feed pump before
it enters the boiler.Thus,using pentane,higher cycle efficiencies are attainable.

在这种情况下可以看出,不像蒸汽,从饱和蒸汽开始,当它膨胀的时候,工作流体变得过热.因此,用它的时候不存在叶片侵蚀的问题.为了提高循环利用率,在膨胀的末期,低压的过热蒸汽可以通过逆流热交换器（或叫同流换热器）,来恢复热量,如果不是这样,将会被冷凝机阻断并且在它离开给水泵进入锅炉之前用它给水加压.因此,用戊烷,就可以达到更高的循环效率
难度很大诶.
