摘　　要：在诸多低NOx 燃烧技术中 ,分级燃烧技术投资小、系统简单、效果显著。用Fluent软件对煤粉锅炉的分级燃烧进行数值模拟研究 ,分析采用分级燃烧方式对煤粉燃烧的影响 ,以达到指导锅炉改造的目的。Within all the low NO x combustion technologies,the staging combustion technology has the advantages of little investment,simple system and remarkable results. In this article,the Fluent software was used to make numerical research on the staging combustion of a pulverized coal boiler. At the same time,it's influence on the burning of coal powder was also analyzed. All this was done to supervise the boiler's alteration.
