不同燃气轮机组成的增压流化床燃烧联合循环(PFBC-CC)变工况性能比较

Off Design Performance Comparison for PFBC CC Constituted by Different Gas Turbines

通过对单轴、分轴和双轴燃气轮机组成的ＰＦＢＣ－ＣＣ变工况性能进行比较，得出由双轴燃气轮机组成的ＰＦＢＣ－ＣＣ为最佳的结论。同时指出，不论哪种燃气轮机用于ＰＦＢＣ－ＣＣ时，空气流量必须能调节，使其变化满足ＰＦＢＣ炉燃烧的要求。

Through comparison to off design performance of PFBC CC constituted by single shaft, split shaft, or two shaft gas turbines, it comes to a conclusion that the best one is consisting of the two shaft gas turbine. The authors point out also that no matter which gas turbine is used in PFBC CC, the air flow must be controllable to enable its change for suiting the requirement of PFBC boiler combustion.
