ANALYSIS OF COPPER-ALOY TUBES' CORROSION BEHAVIOR FOR GENERATOR S' AIR COOLER AND PROTECTIVE MEASURES THEREOF
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.
