摘　　要：文章针对某热轧板坯加热炉超低NOx排放改造需要,在外形尺寸条件受限情况下,提出强化空气分级,增大射流速度的方式,开发超低NOx燃烧器,通过CFD仿真对比样机结构。进行热态实验,对多个样机进行对比验证。改造后加热炉达到超低NOx排放标准。In order to meet the needs of ultra-low NOx emission reform of a hot-rolled slab reheating furnace,the paper proposes ways to strengthen the air classification and increase the jet velocity under the condition of limited external dimensions,develop ultra-low NOx burners,and compare the prototype structure through CFD simulation.A hot state experiment was conducted to compare and verify multiple prototypes.After the transformation,the heating furnace reached the ultra-low NOx emission standard.
