纯十八胺在茂名热电厂1号机组中的应用

Application of pure octadecylamine to Unit 1 in Maoming Cogeneration Power Plant

机组热力设备在停运期间采用纯十八胺保护的技术已趋于成熟 ,且效果比较稳定 ,能有效防止热力设备停运期间的金属腐蚀。茂名热电厂 1号机组为供热母管制机组 ,情况较为复杂 ,实施纯十八胺停运保护具有特殊性 ,为此 ,制定了周密的停运保护方案。在 1号机组上实施纯十八胺停运保护技术后 ,割管检查省煤器管、过热器管 ,两管内壁均形成很好的保护膜 ,憎水性极好 。

The technique of applying pure octadecylamine to outage protection of thermal equipment is reaching maturity, which can effectively prevent metal corrosion of thermal equipment during outage. Consequently, the technique is applied to the outage protection for Unit 1 of Maoming Cogeneration Power Plant adopting heat supply piping main scheme. After cutting the pure octadecylamine protected pipes of the coal economizer and superheater, it was found that both tubes had formed on their inner walls very good protective film with excellent hydrophobicity, which validated the effectiveness of the technique.
