为了降低热不可逆性，Kalina将热力学循环概念化为联合循环的底部部分，其使用NH3-H2O混合物作为工作物质。本文对Kalina循环进行了热力学分析，并编制了计算混合物热力性质的通用程序。研究了关键参数对循环性能的影响。这些参数之一，即涡轮机入口处的混合物浓度，似乎具有关于第二定律效率的最佳值。还研究了这些参数对各部件火用损失的影响。
To reduce thermal irreversibility a thermodynamic cycle was conceptualized for the bottoming part of a combined cycle by Kalina, which uses NH3–H2O mixture as the working substance. In this paper, the Kalina cycle has been analysed thermodynamically for which a general code has been developed for the calculation of thermodynamic properties of the mixture. The effect of key parameters on the cycle performance has been studied. One of these parameters, mixture concentration at turbine inlet, appears to have an optimum value with respect to second law efficiency. The effects of these parameters on the exergy loss of each component have also been studied.
