摘　　要：This paper presents the thermodynamic performance analysis and comparison of four kinds of advanced pressurized fluidized bed combustion combined cycle (APFBC-CC) system schemes, two based on pressurized fluidized bed (PFB) combustion and the other two based on atmospheric circulating fluidized bed (CFB) combustion. The results show that the first scheme avoids high temperature gas filter, but has the lower cycle efficiency and syngas heating value. The second scheme can gain the highest cycle efficiency, however it is better to now lower the filter operating temperature. The third and fourth schemes, based on CFB, have lower efficiencies than the second one. But the fourth one, with preheating air/steam for gasification, can obtain the highest heating value of syngas and gain higher efficiency than the third one.针对增压部分气化 2种增压流化床 (PFB)锅炉半焦燃烧和 2种常压流化床 (CFB)半焦燃烧的先进增压流化床燃烧联合循环 (APFBC CC)方案进行了系统热力性能计算 ,分析比较了主要参数对系统性能的影响 ,结果表明将PFB锅炉高温烟气引入部分气化炉的方案一避开了高温烟气过滤式除尘器 ,但降低了煤气热值和系统效率 ;方案二则可获得较高的系统效率 ,然而高温过滤式除尘器目前技术上有一定困难 ,需降温运行 ;方案三、四采用CFB锅炉半焦燃烧系统 ,其中方案四采用气化空气 /蒸汽预热方法 ,不仅可获得较高的煤气热值 ,而且可提高系统效率 .
