| 摘 要： | 在分析NOx生成机理的基础上，用试验的方法研究了过量空气系数、燃烧器倾角以及顶部燃尽风开度对NOx排放浓度的影响。研究结果表明：在相同负荷下，过量空气系数从1．14（氧量为2．5％）至1．27（氧量为4．5％）的过程中，NOx排放浓度随之增加且；燃烧器摆角自下向上摆动时，NOx排放浓度不断减小；顶部燃尽风开度增大时，NOx排放量降低。

| Abstract: | Based on the investigation of NOx formation mechanism, a coal - fired utility filler which capacity is 1801t/h was studied. The effects on NOx emission of excessive air coefficient, inclination of bumer and the over fire air flow were investigated through experimental method. Parameters changed in experi- ment were oxygen, inclination of burner, and over fire air flow. Test results indicated when excessive air coefficient changed from 1.14 （ oxygen 2.5 % ） to 1.27 （oxygen 4.5 % ）, NOx emission concentration increased; When inclination of burners swung from downward ward to up, NOx emission concentration decreased continually amd when over fire air flow was increased, NOx emission was lowened |
