APPLICATION OF BURNERS WITH COMBUSTION-STABILIZING CAVITY ON A 420t/h ANTHRACITE COAL FIRED BOILER[J]. Thermal power generation, 2002, (4): 52-54. DOI: 10.19666/j.rlfd.2002.04.016.
稳燃腔燃烧器在420t/h无烟煤锅炉上的应用
摘要
对爱依斯万方电力有限公司 1号锅炉燃烧器在设计和运行方面出现的问题进行了比较准确的分析
并运用稳燃腔燃烧器及分级燃烧技术等对其进行了改造。改造后锅炉可在 4 0 %负荷下稳燃
炉膛出口两侧烟温偏差在 2 0℃以内
飞灰可燃物降低
掉大渣灭火次数减少
改造效果显著
Abstract
A comparatively accurate analysis of troublesome problems occurred in design and operation aspects of burners used originally on boiler No 1 at Ais Wang Fang Power Company Ltd has been carried out
and the said boiler was retrofitted using burners with combustion-stabilizing cavity and technique of combustion in steps. After retrofitting
the said boiler can keep sustained combustion under load of 40%
the difference of flue gas temperature at both sides of the furnace outlet being within 20℃
the outfire times due to dropping of big lump slag being decreased. The effectiveness of retrofit to be remarkable.
