W火焰锅炉狭缝式燃烧器燃烧特性研究
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.
