摘　　要：对以自主设计的向心透平为膨胀机的有机朗肯循环低品位热能发电系统进行实验研究,结果表明:蒸发器的火用损失都是最大的,其次是冷凝器和向心透平,透平入口压力0.397 MPa、入口温度100.58℃时,蒸发器火用损失为3.81 k W,占总火用损失50.64%,冷凝器和透平火用损失为2.88和0.82 k W,分别占38.25%和10.89%.在实验基础上,用Aspen7.3模拟增加回热器对系统性能的影响,结果显示:热源温度和蒸发温度不变时,有回热器的ORC系统热力性能优于基本ORC系统.The experimental study was carried out to test the performance of organic Rankine cycle waste heat power generation system by using radial inflow turbine as expander. The result shows that exergy loss of the evaporator is the biggest,the next is the condenser and radial inflow turbine; when inlet pressure of the turbine is 0. 397 MPa and inlet temperature is 100. 58 ℃,exergy loss of the evaporator reaches to 3. 81 k W,accounting for 50. 64% of the total exergy loss,that of the condenser and radial inflow turbine are 2. 88 k W and 0. 82 k W,accounting for 38. 25% and 10. 89% of the total exergy loss,respectively. Based on experimental investigation,making simulation about the effects of adding regenerator on the performance of the system,it turns out that when temperature of the heat source and evaporating temperature is the same,thermal performance of the ORCs with regenerator is better than the basic ORCs.
