| 摘 要： | 利用高温气固悬浮实验台对水泥行业中两种典型煤焦在不同CO2浓度下燃烧时NO的释放特性进行了实验研究，考察了不同CO2浓度气氛下，温度变化和添加生料对煤焦炭氮向NO转化的影响。研究结果表明，随着气氛中CO2浓度的升高，煤焦燃烧时NO的释放速率减小，体积浓度的峰值降低，焦炭氮转化为NO的转化率下降。水泥生料对焦炭氮向NO的转化具有正催化作用；温度升高也会促进焦炭氮向NO的转化。但随着气氛中CO2浓度的升高，升高温度和添加生料对焦炭氮向NO转化的促进作用相对减弱。

| Abstract: | The release of NO from coal char combustion under the atmosphere of different CO2 concentrations was investigated in a high temperature gas-solid reactor with suspension and spray.The effects of temperature and cement raw meal on the release of NO under different CO2 concentrations were discussed.The results indicate that with the increase of CO2 concentration,the rate of NO release,the peak value of NO concentration and the percent conversion of char-N to NO decrease.The percent conversion of char-N to NO ... |
