| 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. |
