- 摘要:
- 对稠油开采设备热采注汽锅炉破损炉管的材料进行了宏观检查、化学成分分析、金相分析、常温力学性能分析,并检测了给水水质,探讨了锅炉炉管在当前条件下的腐蚀机理。结果表明,由于水质原因导致炉管腐蚀以及锅炉在短时间内处于强过热状态,是造成锅炉炉管损坏的原因。
The macrographic investigation and the analyses on chemical composition, metallography and mechanical property at normal temperature of the damaged tube material of thermal recovery steam-injection boiler used for heavy oil recovery were carried out. The feedwater quality was examined and the corrosion mechanism of the boiler tube under present condition was probed into. The main causes of damage of the boiler tube were indicated to be poor water quality inducing tube corrosion and boiler working at strong overheating state for a short term.2008,3(3): 67-69 收稿日期:2007-10-26分类号:TK229作者简介:廖洪波(1977-),男,湖北恩施人,工程师,2000年毕业于中国石油大学(华东)储运工程系,2007年获中国石油大学(华东)石油与天然气专业硕士学位,现从事稠油热采工作.参考文献:
