摘要

某超临界600MW机组旋流对冲燃烧锅炉低氮改造后

由于运行调整不理想

致使锅炉尾部CO浓度偏高且NOx排放未达到预期目标。分析认为

其主要原因是锅炉沿炉膛宽度及深度方向氧量分布不均所致。对此

根据燃烧器改造后的结构特点

对燃烧器参数进行优化调整

在保证NOx排放的前提下将锅炉满负荷时尾部CO浓度由2 000μL/L左右降至100μL/L以下

飞灰可燃物含碳量降至0.5%以下

锅炉效率提高0.8百分点

NOx排放浓度由改造前的400~450mg/m3降至250mg/m3左右。

Abstract

After low-NOxburner transformation of a supercritical 600 MW swirl-opposed firing boiler

the CO concentration in the tail became high and the NOxemission didn't reach the expectations due improper operation adjustment.The analysis shows that the uneven distribution of oxygen along the width and depth direction of the furnace is the main cause.Thus

according to the structural characteristics of the retrofited burners

the burner parameters were optimized.After that

the CO concentration at rated load reduced from2 000μL/L to lower than 100μL/L

the carbon content in fly ash reduced to below 0.5%

the boiler efficiency increased by 0.8%

and the NOx emission concentration dropped from 400~450 mg/m3 to about250mg/m3.
