摘要
燃气火焰中热力型NOx以NO为主，燃烧温度对NO生成起决定作用，空气系数也主要通过改变燃烧温度影响NOx生成。燃烧温度大于1800K时，有较多NO生成。降低燃烧温度与保持高效燃烧相协调是控制NOx生成的关键。
The thermal NOx. in gas-fired flame mainly was NO. The burning temperature was the main reason of the production of NO. The air coefficient effected the production of NOx by changing burning temperature. When the burning temperature was greater than 1 800K, more NO was produced. Reducing the burning temperature and keeping efficient burning were the key to control the production of NOx
