烧结法熟料窑氮氧化物的形成及调控的探究

Exploration into the Formation and Regulation of Nitrogen Oxides in Sintering Process Clinker Kilns

摘要

氮氧化物引起的污染问题日益突出，是当前迫切需要解决的环境问题，氮氧化物的排放已经成为我国现阶段污染治理和减排的重点。本文通过对熟料窑运行过程中氮氧化物的形成机理和分类及对应影响因素和调控进行分析，结合生产实践从料浆成分、固定碳的调整，熟料窑操作过程中风、煤、温度、烧结状态等条件控制，提出相应的对增强熟料窑内操作条件与还原气氛相匹配等方面进行探讨，有效提高熟料窑系统调控氮氧化物排放指标的能力。

Abstract

The pollution caused by nitrogen oxides is becoming increasingly prominent and is an urgent environmental problem that needs to be solved. The emission of nitrogen oxides has become a key focus of pollution control and reduction in China at present. This article analyzes the formation mechanism, classification, corresponding influencing factors, and regulation of nitrogen oxides during the operation of clinker kilns. Based on production practice, it discusses the adjustment of slurry composition and fixed carbon, as well as the control of air, coal, temperature, sintering state and other conditions during the operation of clinker kilns. Corresponding measures are proposed to enhance the matching between operating conditions and reducing atmosphere in clinker kilns, effectively improving the ability of clinker kiln system to regulate nitrogen oxide emission indicators.
