摘要
介绍了一种低温热源发电系统,对系统进行了热力学分析并对工质进行分析,选取综合性能优良的有机物R600a作为循环工质,进行了实验研究。对实验测得的数据进行计算分析,比较了不同热源温度和工质泵的转速下,膨胀机的入口压力、膨胀机转速和蒸汽发生器工作压力的变化规律,以及系统发电量变化规律。
This paper attempts to propose a power generation system for low temperature heat sources.The thermodynamic analysis was made about the system,and as well as the properties of its working medium.With R600a as the working fluid for its good performance,the experiment was conducted and the test data was calculated and analyzed.In the condition of different heat source temperatures and rotate speed of pump,the research compared and analyzed the variation rules of inlet pressure of expander,expander speed,evaporating pressure and the power of system.
