摘　　要：基于某80kW微燃气轮机回热循环改造工作,比较了有后冷器和无后冷器的HAT(Humid Air Turbine)循环性能和需要增加的换热器面积。研究结果表明,对于所研究的微燃气轮机,有、无后冷器的HAT循环系统折合效率和折合输出功相当,与有后冷器的HAT循环相比,无后冷器的HAT循环湿化器更高,体积更大,但是由于省掉了后冷器,其总换热面积(后冷器、湿化器、省煤器换热面积之和)更小,即意味着其投资更低,且无后冷器的HAT循环系统结构更简单,将使系统更加紧凑且控制更容易。Compared was the performance of a 80 kW micro gas turbine recuperative cycle after its conversion to a HAT (humid air turbine) cycle with and without an aftercooler. The needed increase in the heat exchanger area is given. The research results show that for the gas turbine under investigation,both the conversion efficiencies and power outputs of the HAT cycle system with and without an aftercooler are nearly the same. Compared with the HAT cycle having an aftercooler,the cycle without an aftercooler is equipped with a humidifier of a greater height and volume. The total heat exchange area (sum of the heat exchange areas of the aftercooler,humidifier and economizer),however,becomes smaller in the absence of the aftercooler. This means that the total investment will be lower,and the configuration of the HAT cycle system,more simple,thus making the system more compact and its control easier.
