Abstract:

Some problems, such as the short operation cycle, the small amount of the prepared water, the frequent regeneration of the resin and others, existed

in the mixed bed for condensed water fine treatment of the 2×600MW direct air cooled unit of the Shanxi Xingneng Power Generation Company Limited project

phase II. The reasons of the problems were found from several aspects, which include the quality of the mixed bed input water, the purity of the regenerating

agent, the amount of the ammonia added into the feed water and the conveying of the exhausted resin. The improvement measures were proposed, and the practice

shows that the effects of the measures are favorable.
