选用某电厂的实际用煤及焦炭，模拟燃煤电厂的煤炭燃烧过程，在不同温度、助燃气体流量、煤粉粒径和氧含量等多种条件下分别进行实验，得出不同燃烧条件下NOx 的释放规律。实验表明，相同条件下，挥发分越大，氮的转化率也相对越大；煤的粒径越小，氮的转化效率越低；随着助燃气体流量的增加，燃料N转化为NOx 的总转化效率增加；氧含量增加缩短了反应时间，但燃料N总效率变化不大。

The release rule of the NO x under different combustion conditions was researched with choosing the actual coal and coke of a power plant to simulate the coal combustion process in fired power plants at various factors with different temperatures , combustion gas flow , and oxygen content of coal .It showed that the more vol-atile, the greater of the rate of nitrogen conversion under the same conditions .The smaller the particle size of coal, the lower the conversion efficiency of nitrogen .As the combustion gas flow increases , the total conversion efficiency of fuel N into the NO x is increased and the oxygen content increased while the reaction time is shorten , but little change in the overall efficiency of fuel N .
