摘要
Abstract
A leakage issue occurred in the evaporator of the low temperature multi-effect seawater desalination equipment in a coastal power plant.The inspection of operating modes for four seawater desalination equipments show significantly higher corrosion and leak-age rates in intermittently operated systems.Corrosion of evaporator heat transfer tubes may occur under shutdown conditions characte-rized by elevated humidity and localized salt concentration,where improper preservation practices could ultimately cause through-wall corrosion and leakage.For this reason,it analyzes the rationality of the existing shutdown maintenance measures,and proposes improvements.It adopts the dry air maintenance technology to ensure that the environmental humidity is below 40%during the equip-ment shutdown period,which can prevent the corrosion and leakage of aluminum brass material heat exchange tubes in high-tempera-ture and high-humidity environments.关键词
