锦界发电公司3号机组锅炉燃烧器改造前NOx排放浓度约402mg/m3~609mg/m3，采用新型燃烧器器和全炉膛分级燃烧技术对3号锅炉燃烧系统进行了低氮改造。试验结果表明，低氮燃烧器改造后，锅炉在最佳运行状态下，NOx排放浓度可控制在128mg/m3~135mg/m3之间，与改造前相比，NOx排放浓度平均降幅约70%，低氮改造效果非常明显。

The NOx emission concentration of the No.3 boiler in Jinjie Power Plant was about 402~609mg/m3, which can not meet the national policy requirements. Thus, by the new type burner and the whole furnace staged combustion technology, retrofit on the low NOx combustion system was conducted. The experimental results showed that, after the retrofit , under boiler optimum operating condition, the NOx emission concentration was between 128~135mg/m3. Compared with the unit before retrofit , the NOx emission concentration dropped by 70%averagely, indicating the retrofit effect was obvious.
