摘　　要：针对三菱M701F天然气燃气轮机燃烧室建立全尺寸三维单筒燃烧室物理模型,兼顾主燃烧区贫预混燃烧模式和值班火焰扩散燃烧模式的组合特性,采用部分预混燃烧模型,对该单筒燃烧室内的燃烧特性进行了数值模拟研究,获得了满载荷运行工况下全尺寸燃烧室的流场、温度场和污染物分布情况;同时计算分析了不同空气过量系数下过渡段出口面最高温度、平均温度、温度分布系数OTDF以及NOx含量的变化情况。结果表明,随着空气过量系数的增大,最高温度、平均温度及NOx含量均逐渐下降,温度分布系数OTDF则呈逐渐上升趋势。A full⁃scale three⁃dimensional physical model of a single cylinder combustor for the Mitsubishi M701F gas tur⁃bine combustor is established.Considering the combination characteristics of lean premixed combustion mode of the main combustion zone and diffusion combustion mode of the duty flame zone,a partial premixed combustion model was adopted to simulate numerically the combustion characteristics of the single cylinder combustor,and the flow field,temperature field and pollutant distribution in the full⁃scale combustor under full load operating conditions were obtained.At the same time,the changes of the maximum temperature,average temperature,temperature distribution coefficient OTDF and NOx contents at the outlet of transition section under different air excess coefficients were calculated and analyzed.The results show that with the increase of air excess coefficient,the max temperature,average temperature and NOx content gradually decrease,while the temperature distribution coefficient OTDF gradually increases.
