摘要

针对目前选择性非催化还原(SNCR)脱硝系统温度窗口选择及喷氨设计方式的不足

在Fluent软件模拟炉内温度场的基础上

拟定运用声学测温技术对炉膛燃烧区域上部进行有效的温度测量和实时监测

找出合适的脱硝反应温度窗口

并且设计合理的还原剂喷口布置方案。

Abstract

To improve the temperature window selection and ammonia injection design

the Fluent software was adopted to simulate the temperature field in the furnace.On this basis

the acoustic thermometry technology was to be employed to carry out effective temperature measurement and real-time monitoring on the upper part of the furnace combustion zone

then to find out a suitable reaction temperature window and put forward a reasonable layout scheme for ammonia injection.
