| 中文摘要 | 为揭示合成气燃烧过程中氮氧化物的生成机理和抑制措施,利用详细化学反应机理动力学模型研究了CO2稀释对合成气对冲扩散火焰中氮氧化物生成的影响,结果表明:随着合成气成分的变化及稀释剂CO2的添加,扩散火焰结构及不同NO生成机理对总NOx排放的贡献发生显著变化;低火焰拉伸率下主要表现为热力型NO,但在高火焰拉伸率下,因CH4存在,使总NO生成高于不含CH4的合成气;随CO2稀释剂的添加,NOx的排放指数EINOx呈单调下降趋势,并且稀释空气的效果优于稀释燃料的效果.; In order to reveal the NOx formation mechanism and restraining measures during syngas combustion,the effects of CO2 dilution on NOx formation in syngas counterflow diffusion flames were investigated using the detailed kinetic mechanism modeling.The results revealed that the structure of diffusion flames and the percentage of NO in total NOx emission produced via different mechanisms varied with the variation of syngas components and the addition of diluent CO2.At a low strain rate NO is produced mostly due to the thermal mechanism,while at a high strain rate,more NO is produced in syngas containing methane than in syngas without CH4.The emission index EINOxmonotonically decreases with the increase of the CO2 volume percentage.Air dilution has a better effect on the reduction of NOx emission than fuel dilution.; 国家自然科学基金资助项目(50576041); 中国博士后基金资助项目(20070410519) |
