STUDY ON GENERAL PERFORMANCE IN FULLY OPERATING REGIONS FOR GAS TURBINE IN IGCC
【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。
【Abstract】 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.
