整体煤气化燃气蒸气联合循环的火用分析方法

Integrated Gasification Combined Cycle Analyzed by Method of Exergy

利用热力学第二定律，从火用的角度出发，分析计算了整体煤气化燃气蒸气联合循环（ＩＧＣＣ）各组成部分的效能，考查了能量在其中的合理利用情况，系统地提出了一种应用于ＩＧＣＣ的火用分析方法．通过对一个ＩＧＣＣ电厂算例的计算，从火用效率和热效率两个角度对其进行了分析评定，找到了循环中的薄弱环节，对进一步提高ＩＧＣＣ循环的效率和性能具有指导意义．

Integrated gasification combined cycle is analyzed by application of the second law of thermodynamics and the method of exergy. Thermal efficiency and weakest part of the cycle are found for a plant such that further improvement of the system could be made.
