摘　　要：低温余热动力回收热动循环应与余热流的变温特性很好地匹配才能获得较高的转化效率,采用低沸点有机工质HFC125实现超临界动力循环,能很好地逼近变温热源下的理想循环,从而获得较好的效果。采用效率来评价余热回收动力循环时,可以得到相对全面的结论。In order to improve the performance of the thermal power generation cycle driven by low-temperature waste heat, the system should be constructed to make the temperature of the heated working fluid match the changing temperature of the fluid carrying waste heat, the supercritical Rankine cycle using organic fluid HFC125 as the working fluid is proved to be the best promising system driven by waste heat. The energy efficiency method should be used to evaluate the overall performance of the cycle.
