摘　　要：建立了钢铁厂燃用高炉煤气的简单循环燃气轮机装置模型,根据经典热力学和燃气轮机循环理论编制了循环热力性能计算程序,计算了循环功率和效率随压比的变化关系。结果表明存在不同压比分别使循环功率和效率达到最大值,提高涡轮进口燃气温度和降低煤气压缩机进口温度有利于提高循环性能。A simple-cycle gas turbine model with blast-furnace gas （BFG） in steel mill is built. A computational program for the cycle thermodynamic performance analysis is conducted based on classical thermodynamics and gas turbine cycle theory. The characteristics of the cycle power and efficiency versus the compressor＇s pressure ratio are obtained and the results indicate that different pressure ratios exist, which lead to the maximum power and the thermal efficiency of the cycle, respectively. The cycle performance can benefit from the increase in the inlet gas temperature of the turbine and the decrease in the inlet temperature of the BFG compressor.
