我国太阳能有机朗肯循环研究现状

Research status of solar organic Rankine cycle in China

太阳能具有易转化为低温热源的特性,而有机朗肯循环是利用低温热源或工业余热发电的理想方式,两者相结合形成基于太阳能的有机朗肯循环发电技术。综述了我国光热太阳能发电技术和市场现状以及针对有机朗肯循环的研究现状。经分析发现,目前研究中理论分析或计算机模拟较多,缺乏实际应用的验证。论述了有机朗肯循环工质的选择、循环性能分析方法以及所面临的问题和改善方法。

Solar energy can be easily changed into the low temperature heat source. And organic Rankine cycle is an ideal way for the electricity generation from the low temperature heat source or industrial waste. Combination of these could form solar organic Rankine cycle power generation technology. The technologies of concentrating solar power, current situation of its market and the research status of organic Rankine cycle were summarized in this paper. It could be found that most of studies focused on theoretical analysis and numerical simulation, which lacked the validation of the practical application. The selection of working medium, methods for the cycle performance analysis, problems it faced and their improvement methods, were discussed in this paper as well.
