| 摘 要： | 研究了燃料燃烧过程中 N- S间的相互作用 .分别从实验和数值计算的角度总结 SO2对 NOx 及含氮中间产物生成和释放的影响 ,并试图通过反应机理来解释 .SO2 在贫燃料状态下能降低热力型 NO的释放 ,抑制富燃料状态下快速型 NO的生成 ,对贫燃料及富燃料状态下燃料型NO释放的影响不能得到统一定论 ,但 N- S间确实发生了复杂的相互作用 .数值计算的结果与实验相差较大 ,但具有一定参考价值 ,且能得到实验难以测量的中间产物的浓度变化趋势

| Abstract: | The N S interaction during fuel combustion has been studied in this paper.Experimental and numerical results on the effects of SO 2 on the formation and emission of NO x have been concluded,which can be explained by reaction mechanism.The results show that SO 2 can reduce the emission of thermal NO under fuel lean condition and inhibit the formation of prompt NO under fuel rich condition.However,we cannot get a general agreement on the effect of SO 2 on the emission of fuel NO.Complex N S interactions occur.Although there are great discrepancies between numerical and experimental results.the former can predict the concentration of intermediate species,which is difficult for measurement. |
