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 kW,占总(火用)损失50.64％,冷凝器和透平(火用)损失为2.88和0.82 kW,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.
Abstract:
The experimental research on the organic Rankine cycle low-grade thermal power generation system with self-designed centripetal turbine as the expander shows that the (exergy) loss of the evaporator is the largest, followed by the condenser and the centripetal turbine. When the inlet pressure of the turbine is 0.397 MPa and the inlet temperature is 100.58°C, the evaporator (exergy) loss is 3.81 kW, accounting for 50.64% of the total (exergy) loss, and the condenser and turbine (exergy) losses are 2.88 and 0.82 kW, accounting for 38.25% and 10.89% respectively. On the basis of the experiment, using Aspen7.3 to simulate the impact of adding regenerator on system performance, the results show that: when the heat source temperature and evaporation temperature are constant, the thermal power of the ORC system with regenerator Performance is better than basic ORC system.
