摘　　要：基于气体多变压缩以及等温涡轮燃烧技术,提出了一种改进的概括性卡诺循环燃气轮机,通过模型预测分析了其性能,并与传统燃气轮机进行了比较。结果表明,改进的概括性卡诺循环燃气轮机的效率有很大的提高,其循环是一种接近概括性卡诺循环的气体动力循环和一个蒸汽动力循环所构成的联合动力循环,有利于降低NOx的排放。Based on polytrophic process of air compression and isothermal gas combustion inside the turbine, an improved gas turbine with generality Carnot cycle is suggested. Its performance has been predicted with a mathematical model compared with traditional gas turbine. The results show that the heat efficiency of the improved gas turbine is higher than that of traditional. The suggested cycle combines gas cycle and steam cycle, where the NOx emission can be easily decreased.
