摘要

德国Ｓｔｅｉｎｍ¨ｕｌｅｒ公司在一台热功率为１５ＭＷ试验炉上，采用三级燃烧技术降低ＮＯｘ生成量，主要为改变过剩空气系数、主燃料与还原燃料分配比例、分级风喷射速度、还原燃料喷射速度、还原区长度、煤粉细度等。试验结果应用于一台５００ＭＷ锅炉，其ＮＯｘ排放量可控制在４００ｍｇ／ｍ３。

Abstract

Abstract Three-staged combustion was experimented by Steinmuller （Germany）on a 15MW test boiler to reduce NO x formation.The reduction of NO x was reached mainly by changing coefficient of excess air

proportion between main fule and reducing fuel

velocity of staged air

feeding velocity of reducing fuel

length of reducing zone and pulverized coal fineness

etc.The results of this experiment were then applied to a 500MW boiler with a NO x emission within 400mg/m 3.
