某电厂 10 2 5t/h锅炉在安装调试加氧吹管中发生了灼烫事故。发生事故的原因是对吹管加氧系统临时管路蒸汽吹扫不彻底 ,管路中存在油脂 ;另外 ,没有对氧气支管路和压力表支管路蒸汽吹扫 ,而产生爆燃。在对加氧临时系统采取了一些防范措施、对管道加强了蒸汽冲洗、在加氧母管末端安装了逆止阀等防范措施后 ,在该厂 4号锅炉和锅炉加氧吹管时未发生类似事故
A power plant 1025t / h boiler installation and commissioning of oxygen blowing pipe burning occurred in the accident. The reason for the accident is that the steam in the temporary pipeline of the oxygen blowing system is not completely purged and there is grease in the pipeline. In addition, no steam is purged to the oxygen branch pipeline and the pressure gauge branch pipeline, and deflagration occurs. After taking some precautionary measures against the temporary oxygenation system, strengthening the steam flushing on the pipeline, installing the check valve and other precautionary measures at the end of the oxygen-enriched mother pipe, no similar situation occurred at the No. 4 boiler and the boiler oxygen blowing pipe at the plant ACCIDENT
