摘　　要：对贫油预混预蒸发(LPP)低污染燃烧室单头部三级旋流器进行燃烧性能试验,研究不同的油气比、进口空气流量和进口空气温度以及值班级喷嘴安装位置对燃烧室出口截面燃烧性能的影响,获得了燃烧室出口截面温度分布、燃烧效率以及污染物排放的规律.试验结果表明:1油气比增加,NOx排放相应增加;头部A燃烧性能稍优于头部B;2同一油气比下进口空气温度越高,其燃烧污染物排放越多;进口空气流量越大,污染物排放越少;3值班级喷嘴安装位置对LPP低污染燃烧室燃烧性能有一定影响.Combustion performance experiment was conducted for three-stage swirler of lean premixing and prevaporizing（LPP）low emission combustor with single dome.In order to investigate the effects of different fuel air ratios,inlet air mass flow rates,inlet air temperatures and positions of pilot atomizer on the combustion performance of combustor outlet,and the outlet temperature profile,combustion efficiency and pollutant emission rules of combustor were obtained.The experiment results show：（1）emission of NOx increases with the fuel air ratio increasing,and the combustion performance of dome A is better than that of dome B;（2）at the same fuel air ratio,if inlet air temperature increases or inlet air mass flow rate decreases,pollutant emission raises correspondingly;（3）position of pilot atomizer has effect on the combustion performance of LPP low emission combustor.
