| 摘 要： | 在循环流化床实验台上，以地东北地区两种典型煤，彩屯煤和俊德煤分别进行了燃烧时ＮＯｘ排放的实验研究。考察了不同的流化床温度、一次风率、二次风口位置及比例和循环倍率对ＮＯｘ排放浓度的影响。表明：在循环床温度范围，温度对ＮＯｘ排放浓度影响不显著；

| Abstract: | The NO x emission during the combustion of two type coals with different volatile matter contents has been studied on the experimental bench of the circulating fluidized bed (CFB). The nitrogen oxide (NO x ) emission is studied under different conditions including the combustion temperature,the primary air ratio,the injection position of the secondary air as well as the recirculation rate. It is found that the NO x emission substantially increases with primary air ratio increasing,the NO x emission will decrease with increasing the recirculation rate and the secondary air position is the sensitive parameter for decreasing NO x emission. |
