| 摘 要： | 电厂锅炉在运行过程中由于氧化皮脱落沉积在管内 ,导致蒸汽流量减少 ,壁温大幅升高 ,使金属加速蠕变胀粗 ,最终爆管的现象常有发生。通过分析氧化皮的形成、影响氧化皮形成的因素以及氧化皮剥落的规律来探讨防止和减缓氧化皮生成和剥落的方法。

| Abstract: | In some power plants because oxidized layers inside the hot pipes is exfoliated from the wall and accumulated inside, the steam flow would be decreased greatly. As a result, the great temperature rise accelerates the metal creeping under high pressure and enlarges the size of pipe, the pipe burst occurs finally. Focusing on the mechanism of creation and development and rules of oxide layers, the approaches are discussed to retard and relax the exfoliation from the wall. |
