摘　　要：针对某电厂600 MW超临界四墙切圆燃煤锅炉炉内燃尽风开度大小对炉内NOx浓度分布的影响,采用了试验研究和数值模拟相结合的方法,两者结果吻合情况较好,共进行了4个工况,主要分析了炉内煤粉燃烧过程中产生NOx的影响因素及生成规律,得出了SOFA风风门开度大小对炉内NOx浓度分布有较大的影响。A power plant 600MW supercritical four walls tangentially fired boiler furnace OFA opening size to impact on the furnace NOx concentration distribution, using the experimental study and numerical simulation method of combining, both results agree is better, a total of four conditions, analyzes the influencing factors of NOx produced during combustion of pulverized coal furnace and generate rule, come to the opening size of burnout air damper on the furnace NOx concentration distribution has a greater impact.
