摘要
Researches on the NOx emission characteristics of HT （Huangtai coal）, LC（Laicheng） coal are carried out in different atmosphere. The results show that the NOx emission time is postponed in O2/N2 atmosphere mixed with CO. The releasing times of volatile nitrogen and char nitrogen approach, the amount of NOx reduces. In high 02 concentration atmosphere mixed with CO2, the nitrogen releasing times cane ahead of time, NOx congregate in the beginning of the combustion. On the contrary, nitrogen releases separately, and the amount of NOx reduces greatly.
