摘　　要：研究整体煤气化联合循环燃料切换时对余热锅炉蒸汽系统运行方式的影响,提出几项有效的改进措施。并利用联合循环蒸汽系统变工况计算方法、计算并分析不同运行方式的热经济性。结果表明整体煤气化联合循环以备用燃料运行时,这些改进措施能有效改善蒸汽系统的热力性能。研究结果可应用于整体煤气化联合循环机组的方案设计,具有一定的工程应用价值。The effects of IGCC fuel changeover on the operation mode of HRSG(heat recovery steam generator) steam system are investigated in this paper. Several effective measures to improve unit performance are raised. With the off-design calculation, thermal economics analysis of steam system is conducted. It is indicated that these measures can effectively improve the performance of steam system when IGCC operates on standby fuel. Research results can be used to the IGCC unit design and are important for engineering application.
