| 中文摘要 | 本報告係林口電廠二號機冷凝器之破管分析案例,文中說明破管之外 觀、微結構以及管垢組成,此外,海水中之強腐蝕因子諸如硫離子、NH��+亦做 檢測。從這些資訊知此次破管原因係一時性高含砂量降低了保護膜之特性,和局 部的高水流導致衝撞侵蝕所引起。 |
| 英文摘要 | This paper deals a failure analysis on the condenser tube of Lin KoThermal Power Station unit 2. Appearance, microstructur-3 and composi tion of the existing scale on inner tube surface are examined. In addition,the affection of polluted species such as sulfide ion and NH4+ are alsoinvestigated. It concludes that the reason of this failure is temporarilyhigh sand concentration in sea water lowers the performance ofprotective film on tube surface, in turn, impingement-attack oescursunder locally high fluid condition. |
