| 摘 要： | 当采用朗肯循环方式回收低温余热（350℃以下）的动力时，不宜采用水作工质，而使用一些低沸点有机物的有机朗肯循环（ORCs），则能获得较高的能量转换效率。有机朗肯循环可分为亚临界条件下的动力循环与超临界条件下的动力循环，超临界条件下的动力循环在热端换热器中（余热加热蒸汽发生器）能获得较好的温度匹配和较高的火用]效率。

| Abstract: | In the case of low-temperature waste heat （below 350℃） recovery, it proves to be improper to use water as working fluid circulated in the Rankine Cycle, however, Organic Rankine Cycles （ORCs） ultilizing low boiling point organic fluids own the merit of high energy recovery efficiency. Organic Rankine Cycles can be categorized into sub-critical and supercritical power generation cycle. Better temperature matching performance in the waste heat recovery steam generator and higher exergy efficiency can be obtained through supercritical Organic Rankine Cycle. |

| Keywords: | low-temperature waste heat low boiling point working fluid supercritical exergy efficiency |
