研究表明：煤中氮主要以有机形态赋存；
煤中氮元素在煤燃烧过程中会转化为各种氮的氧化物，从而造成环境污染。
During the combustion process of coal, the nitrogen element in coal may turn to various oxides of nitrogen, thereby, resulting in ambient pollution.
在流化床燃烧条件下，N2O由煤中的氮转化而来。
N2O is formed by nitrogen in coal under fluidized bed conditions.
在不同煤种的焦炭燃烧实验中，均有HCN在烟气中生成，因此hcn的气相氧化过程是焦炭氮向n 2o转化的一条途径。
HCN is produced during combustion of chars from different rank coals. That means HCN oxidation is a pathway for N2O formation during char combustion.
