摘　　要：本文研究了利用余热制冷进气冷却的回热燃气轮机系统,并对该系统性能进行了模拟计算,得到了压比、流量比等参数对系统性能的影响规律。并通过与常规回热循环比较,指出利用余热制冷来进气冷却的方式能使系统效率提高11%,是提高燃气轮机系统性能的有效途径之一。In this paper a regenerative gas turbine system was proposed. This system has an inlet air cooling powered by waste heat. And a simultion of system is carried out. Influence of compressive ratio and flow ratio on whole system performance were evaluated. Compared to conventional regenerative cycle, the novel system has the relative improvement of 11% in energy efficiency. It shows that the inlet air cooling powered by waste heat is one of the effective way of improving system performance.
