| 摘 要： | 在Rijke管产生的强迫脉动驻波声场下，以甲烷层流部分预混火焰为研究对象，比较了脉动燃烧与稳态燃烧下NOx随当量比的变化规律，结合微细热电偶、火焰探针，讨论了火焰内部温度场和组分浓度变化，分析了脉动燃烧下NOx降低机理。结果表明脉动燃烧下甲烷部分预混火焰的NOx降低，其主要机理为：脉动燃烧下火焰的峰值温度低，温度分布均...

| Abstract: | The NO_x emission between pulsating combustion and non-pulsating combustion were compared on methane laminar partially premixed flame under acoustic forcing with Rijke tube. The mechanism of NO_x was analyzed by micro-thermocouple,water-cooled sampling probe.The experimental results show that compared with non-pulsating combustion,pulsating combustion produced less NO_x emissions.There are three reasons including:(1) peak temperature was reduced and the distribution of temperature was more uniform,(2) the o... |
