摘　　要：社会的可持续性发展,使得对环境的要求达到一个新的高度。减少氮氧化物的排放是一个亟待解决的问题,燃料再燃技术是解决此问题的一个十分可行的方法。文章分析了燃料再燃技术的原理,论述了超细煤粉再燃NOx的排放在中试试验炉上的试验和数值模拟结果,中间储仓式热风送粉系统采用三次风再燃技术降低NOx的排放,结果表明这两种燃料再燃技术都可有效降低氮氧化物的排放。The sustained development of society put the environment problem to a new status,among those facets reducing the discharge of NOx is especially important.This paper analysised the principle of fuel reburning.NOx emission of experiment and numerical simulation about general combustion and micronized coal reburning in combustion research facility was processed.The emission of NOx on the reconstructing for a conventional system of the hot air transferring pulverized coal was processed.The result show that the two reburning technique can reduce NOx emissions effective.
