摘　　要：对三种不同排烟方式HAT循环的模拟分析表明,在总压比一定时,排烟方式对比功影响很小,采用引风机排烟的HAT循环比直接排烟及回热法排烟的电效率最多分别高出1和1.5个百分点。最高效率时的引风机压比在1.5～1.6左右。引风机排烟带来的压缩耗功下降和湿化器出水温度降低是效率升高的主要原因。水回收率相对偏低,且性能受烟气冷凝温度和引风机压比影响较大。Performance of Humid Air Turbine (HAT) cycle with three kinds of exhaust discharged methods were simulated.The results show that the specific work is affected slightly by the exhaust discharged methods for certain total pressure ratio.But the efficiency of the HAT cycle discharging the exhaust with induced draft fan (IDF) is 1 and 1.5 percentage points at most higher than that of HAT cycle discharging exhaust directly and HAT cycle discharging exhaust by recuperation respectively. The pressure ratio of the ...
