摘要

介绍了一种船用主机中低温余热回收系统。为了提高中低温余热驱动的火力发电循环的性能,应构建使被加热工质温度与携带余热的流体温度变化相匹配的系统。以纯有机流体R134a为工质的超临界朗肯循环被证明是最有前途的废热驱动系统。应采用火用效率法评价循环的整体性能。

Analysis of a Middle-Low Temperature Waste Heat Recycling System
A middle-low temperature waste heat recycling system for marine main engine is mentioned in this article. In order to improve the performance of the thermal power generation cycle driven by middle-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 pure organic fluid R134a as the working fluid is proved to be the best promising system driven by waste heat. The exergy efficiency method should be used to evaluate the overall performance of the cycle.
