基于同一微燃机,构建了注水回热(RWI)、HAT、部分空气湿化(PHAT)、压气机入口喷雾冷却的HAT(AHAT)循环模型,对各循环的性能进行了模拟分析并对比了效率和比功。结果表明,在可比条件下,空气湿化循环功率和效率较回热循环分别提高40%以上和5个百分点左右。研究结果为微燃机改造为空气湿化循环提供了依据和理论指导。
The paper analyzed the performance of Recuperated Water Injected (RWI) cycle, Humid Air Turbine cycle (HAT), Part-flow HAT cycle (PHAT) and Advanced Humid Air Turbine (AHAT) cycle based on a micro-gas- turbine. The results show that a remarkable increase in specific work (up to 40%) and efficiency (up to about 5 percentage points) can be achieved. The investigation provides reference for retrofitting the micro turbine to humidified air turbine cycles.
