摘要

针对台山发电公司600MW机组锅炉氮氧化物排放高的问题

提出了双分段高效复合低氮燃烧器的改造方案

并在3MW热态试验台上进行了试验研究。结果表明

采用两段SOFA运行方式比一段SOFA运行方式NOx排放值更低

与不采用空气分级的燃烧工况相比

NOx排放可以降低60%左右

而CO和飞灰含碳量的数值变化不大。目前

该公司600MW机组锅炉在燃用80%神华煤+20%石炭煤时

NOx排放值约为450mg/m3

锅炉低NOx改造后

预计NOx排放值将小于180mg/m3。

Abstract

The NOx emitted from the 600MW unit boiler of Taishan Power Plant had a high concentration.Thus

the transformation scheme for double-segment compound low NOx burner with high efficiency was proposed

and the experiment was performed on a 3 MW thermal test-bed.The results showed that

the NOx emission was lower in two-stage SOFA operation mode than in single stage SOFA operation mode.Compared with the combustion condition with no air staging

the NOx emission can be reduced by about 60%

but the concentration of CO and carbon content in fly ash had no obvious change.At present

the 600 MW unit boiler in Taishan Power Plant uses Shenhua coal(80%) and Shitan coal(20%) as the fuel

and the NOx emission is about 450 mg/m3.After the low NOx combustion transformation

the NOx emission will be lower than 180 mg/m3.
