利用专用流程计算软件建立了400 MW级IGCC电站系统模型,在此基础上对不同整体化率设计下的系统性能进行了评估,得出最优的整体化率,并通过进一步分析,确定了影响整体化率选择的因素,定量分析了各因素取值变化对空分系统的影响.结果表明：IGCC电站的最优空分整体化率与燃气轮机性能、气化工艺、空分装置主空压机效率等有关,其中燃气轮机性能随抽气量的变化是影响空分系统整体化率取值的关键因素.

The integration extent of air separation unit and gas turbine in IGCC power plant is an important optimization parameter.In order to evaluate the influence of air separation unit integration extent on IGCC performance,process model based on a 400 MW IGCC system is built and an optimized integration rate is obtained.The factors influencing the integration rate determination are discussed and quantitatively analyzed.Analysis results show that the influence of extraction air flow on gas turbine performance is the key factor in determining the ASU integration rate.
