摘要

以国内首台自行设计制造的超临界600MW机组W火焰锅炉为例

应用Fluent软件研究不同负荷下炉内燃烧过程中速度场、温度场、CO浓度场、O2浓度场的分布情况

分析了负荷变化对炉内燃烧稳定性的影响

得出不同负荷下W火焰锅炉的燃烧特性

以及低负荷下易产生水冷壁、冷灰斗结渣及爆管的位置

为同类锅炉设计、运行和改造提供参考。

Abstract

Taking the first domestic supercritical 600MW unit W-flame boiler as an example

the Fluent software was applied to conduct numerical investigation on velocity field

temperature field

CO and O2 concentration field in furnace during combustion at different loads.The effect of unit load on combustion stability was analyzed

and the combustion characteristics of W-flame boiler under different load conditions were obtained.Moreover

the locations where tube burst and slagging easily occurs at low load were found

which can provide references for design

operation and retrofitting of the same type boilers.
