| 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

| 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. |
