摘要

通过模拟非共沸混合工质和纯工质在低温烟气有机朗肯循环(ORC)系统中的特性

考察了不同质量比下的混合工质的热力学特性和经济特性

并与纯工质进行对比。结果表明:混合工质在基本ORC系统中的热效率和质量流量介于其组元纯质之间

但在加装回热器后

部分混合工质的系统热效率优于纯工质

且混合工质较纯工质具有更小的膨胀比和单位功量;含有1种相同组元的二元混合工质

其组元之间临界温度差越大

热力学性能变化幅度越大。

Abstract

By simulating the characteristics of non-azeotropic mixtures and pure fluids in a low-temperature waste heat organic Rankin cycle(ORC)

the economic and thermodynamic properties of the mixtures with different proportions were compared with each other and with that of the pure working fluids.The results show that

the cyclic thermal efficiency and mass flow rate of the mixtures in basic ORC system layed between that of each pure fluid.However

after the regenerator was installed

some of the non-azeotropic mixtures had higher thermal efficiency than the pure substance

and the non-azeotropic mixtures had lower pressure ratio and unit power required for UA.For the two-component non-azeotropic mixtures with one of the components be the same

the larger the critical temperature difference between the two components

the greater the thermodynamic performance changed.
