摘要

神东热电厂发电机空冷器铜管腐蚀严重

分析认为其原因为铜管选材不当、冷却水流速低以及停运期间缺少适当的保护

为此提出 3条措施 :(1)更换空冷器全部铜管

并应选用含砷的铜合金管材 ;(2 )保证冷却水流速不低于 1m/s ;(3)停运期间采取适当的保护。

Abstract

Serious corrosion of air cooler’s copper-aloy tubes has occurred in generators of Shendong Thermal Power Plant. It is considered from analysis

the main causes are:non suitable selection of copper tubes’ materials; low flow velocity of the cooling water; and shortage of suitable protection during the time of shutdown. For these reasons

three protective measures have been put forward

namely: （1） replacing all copper tubes of the air coolers; （2） ensuring the flow velocity of cooling water doesn’t lower than 1m/s; （3） suitable protection must be taken during the time of shutdown.
