摘　　要：烧结过程中产生的氮氧化物主要来自于固体燃料中挥发份的燃烧,而安钢烧结使用的固体燃料以无烟煤为主,挥发份含量较高,因此氮氧化物排放较高。为验证低氮固体燃料对烧结污染物减排的作用,技术人员在2#烧结系统组织了低氮煤和焦粉替代高挥发份无烟煤的工业实验,对比分析了减排效果及燃料成本变化。The nitrogen oxides produced in the sintering process mainly come from the combustion of volatiles in solid fuels.The solid fuel used by Anyang Steel's sintering machine is mainly anthracite,which has a higher volatile content,so nitrogen oxides emissions are higher.In order to verify the effect of low-nitrogen solid fuel on the emission reduction of sintering machine pollutants,technicians organized an industrial experiment in which low-nitrogen coal and coke powder replaced high-volatile anthracite in 2#sintering machine,and obtained experimental conclusions.
