文档介绍：锅炉结焦原因分析、 打焦方法及方法
摘 要: 锅炉结焦是火力发电厂常常碰到问题, 它发生发展对锅炉安全运行带来很大危害, 结焦会破坏正常燃烧工况, 引发掉焦灭火事故, 降低锅炉出力, 破坏正常水循环, 造成爆管事故, 严重时还会使炉膛排渣口堵塞而被迫停炉打焦。 本＃1锅炉出现了严重结焦现象, 结焦部位关键分布在和燃烧器同高度水冷壁区域和“V”形冷灰斗水冷壁部位。 因为发觉立即, 采取方法适当, 经过一个多星期连续排班打焦, 将积存焦渣全部打下, 避免了一次机组非计划停运事故发生, 保障了机组安全运行。

Abstract: Coke is a thermal power plant boiler frequently encountered problems, Its occurrence and development of the safe operation of boiler great harm, Boiler Coking would destroy the normal combustion condition, Boiler cinder fall accident caused by flame, Reduce the boiler output, Disruption of normal water cycle, Accidents caused by squib, Serious Shihai furnace slag port plug will be forced to shutdown playing coke. # 1 boiler experienced serious coking phenomenon, mainly in the coking site with the burner with a high degree of water-wall region and "V"-shaped buckets of cold gray water-wall parts. The discovery of timely and appropriate measures taken, after more than a week of continuous scheduling to play coke, the coke residue will accumulate all laid, avoid an unplanned unit outage incidents, to protect the safe operation of the units.
Keywords: boiler coking; hazards; playing coke; provide security.
