摘　　要：采用热天平和沉降炉对某台420t/h锅炉的四种主要燃烧煤种进行试验研究,分析这四种煤种的燃烧特性和NOx排放特性。对比几种常用的低NOx燃烧方式,并对现行的燃烧器进行诊断分析,认为采用SOFA空气分级燃烧方式可达到预期的改造效果。Experimental research on four coals of a 420 t/h unit boiler was carried out by thermal balance and sedimentation furnace. The combustion features of coals and the NOx emission of coals were analyzed. The contrast analysis was conducted between several low NOx combustion technologies, and the current burner was diagnosed. The boiler reforming in the scheme of SOFA can meet the NOx emission standard of power plant.
