摘要:
以热力学第一定律和第二定律为基础,对有机朗肯循环低温余热发电系统进行了热力分析.用Aspen plus软件,对循环系统中的几个重要影响参数进行了模拟研究.研究结果表明:工质处于饱和状态时系统的性能最优；增大蒸发压力或减小冷凝压力都能提高系统的热效率和(火用)效率.在原有基本朗肯循环的基础上,采用乏气回热循环或中间抽气回热循环,二者均能改善系统的性能.
Abstract:
Theral analysis of Organic Rankine Cycle(ORC)drivenDy low-temperature waste neat was investigated based on the first and second laws of thermodynamics. The system was simulated with the softwareAspen plus. The effects of superheat, subcooling, evaporation temperature and condensing temperature on theperformance of the system were analysed respectively. The results show that the system with saturated workingfuid gives the best performance, the thermal efficieney and exergy efficiency were improved by inereasing e-vaporation preseure or reducing condensing preseure, The regenerative ORC gives belter performance than bas.ic Rankine cycle.
