稻壳混煤燃烧对NO_x排放的影响

Influence of rice hull mixed coal combust on NO_x emission

利用循环流化床试验平台分析稻壳混煤燃烧对NOx排放的影响。结果表明,贫煤混合稻壳后燃烧,当燃烧温度恒定时,NOx的排放量随着燃料中稻壳所占比重增加而降低;当燃料中稻壳所占比重恒定时,NOx的排放量随着燃烧温度的升高而增加。

The influence of rice hul mixed coal combustion on NOx emissions is analyzed by using fluidized bed experimental platform. The results show that,after mixing the lean coal and the rice husk,when at the constant combustion temperature,the emissions of NOx is decreased with the increase of the proportion of rice hul in the fuel;when at the constant proportion of rice hul in the fuel,the emissions of NOx is increased with the increase of the combustion temperature.
