摘　　要：本文基于对ＩＧＣＣ系统的全面分析研究，归纳总结了导致燃气轮机工况变化的主要原因；应用双开口变量（整体空分系数（Ｘａｓ）和氮气回注系数（Ｘｇｎ））和折合系统效率的概念，建立了ＩＧＣＣ中燃气轮机全工况特性简化模型；并通过大量定量计算，得出不同Ｘａｓ和Ｘｇｎ组合条件下，ＩＧＣＣ中燃气轮机全工况网络特性，为确定系统变工况最佳调节规律提供全面信息。In this paper, the key factors, which affects the off-design characteristic of gas turbine (GT) in IGCC, are analyzed; the off-design characteristic model of GT with two opening variables - ASU-integrated coefficient (Xas) and Nitrogen-reinjected coefficient (Xgn) - and IGCC overall efficiency, is investigated; the performances both resulting from the part-load working condition and the varied atmosphere temperature are calculated and compared under various possible combination of Xas and Xgn; a lot of computation is carried out and some helpful results are obtained.
