摘　　要：针对燃煤气的闭式ＳＴＩＧ循环，给出气化系统能量转化效率的计算式，计算三种典型气化炉分别采用高温干法和常温湿法净化系统的能量转化效率，同时分析能量转化效率对整个循环系统热效率的影响。With respect to a coal gas fired closed STIG cycle plant presented in this paper is an equation for calculating the energy conversion efficiency of a gasification system. With the use of a high temperature dry method and constant temperature wet method calculated is the gasification system energy conversion efficiency of three typical gasification furnaces. In addition, an analysis is conducted of the effect of energy conversion efficiency on the cycle system thermal efficiency as a whole.
