分解炉内CO2浓度对煤焦燃烧NO释放的影响
Effect of CO2 concentration on the release of NO from char combustion in cement precalciner
摘要
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 greatly rises due to the catalysis of cement raw meal, while the catalysis of the cement raw meal becomes weakening with the increase of CO2 concentration.It is also found that the conversion of char-N to NO increases with the rise of temperature.However, the effect of temperature on the NO release reduces with the increase of CO2 concentration.关键词
