摘    要:针对CH4 火焰中CO2 浓度对于NO降解的影响进行了详细地分析研究。结果表明 :过量空气系数对于NO的降解有着很大的影响。和氧化性气氛相比 ,还原性气氛更有利于NO的降解。同时还原性气氛中CO2 的存在降低了NO的降解率 ,而氧化性气氛中CO2 的存在能够促进NO的降解。在还原性气氛中 ,随着CO2 浓度的升高 ,其继续减少NO降解率的作用也越来越不明显

关 键 词:O2/CO2  NO  降解

Abstract:Systematic experiments on the effect of CO-2 on NO reduction in CH-4 flame were carried out. It was found that various stoichiometric ratios had a pronounced influence on reduction of CO. Compared to the condition of lean fuel, NO reduction ratio is higher under the condition of rich fuel. Existence of CO2 has a positive effect on NO destruction, but on the contrary, CO-2 gives a negative effect evidently on NO destruction under rich fuel condition. It was also noticed that the negative effect of CO-2 on NO destruction under ric-h fuel condition faded out with the continuous increase of CO-2 concentration.
Keywords:O-2/CO-2  NO  reduction
