煤粉锅炉分级燃烧降低NOx排放的试验结果分析

摘要

The experimental results of adopting stage combustion technique to retrofit WGZ401/100-12 type boiler at Wulashan Power Plant are analyzed in this paper,and factors having effects on production of NOx in the furnace,such as burnout air ratio,distribution of secondary air across the section of furnace,boiler load and tertiary air being on or off,have been pointed out.%通过对乌拉山电厂WGZ410/100-12型锅炉分级燃烧技术改造后的优化调整试验结果的分析，指明了燃尽风份额、二次风沿炉膛断面的分布、锅炉负荷、三次风投停等因素对炉内NOx生成量的影响。
