摘要

某自备电厂#1、#2机组锅炉燃烧器NOx排放值在500

00 mg/Nm3之间

为达到国家标准

采用水平与垂直方向分级而形成立体分级燃烧技术进行改造。改造后经测试

在300 MW负荷

省煤器出口含氧质量分数ω（O2）

3.5%的前提下

NOx排放≤350 mg/Nm3[ω（O2）=6%

]

飞灰含碳量不大于改造前的水平

改造效果显著。

Abstract

The boilers of the #1 and #2 units in the power plant

whose NOxemission level are between 500 mg/Nm3 and 600mg/Nm3

have been improved by using staged combustion at horizontal and vertical directions. After the improvement

the NOxemission is successfully reduced to less than 350 mg/Nm3 under 300 MW load with ω（O2） <3.5% outlet oxygen level.Meanwhile

the carbon contents of fly ashes are no more than previous combustors. These results suggest that this technology could significantly reduce the NOxemissions in boiler combustion.
