Research on the reuse of intermediate water in circulating cooling water system

Huaneng Beijing Cogeneration Power Plant uses the intermediate water as make-up water for the circulating cooling water system, as a result, the operation index of circulating water (including the corroding rate and microorganism) exceeds the relevant standards in case that the ammonia nitrogen in make-up water exceed standards. The damage of above-mentioned problems was introduced and the conversion of ammonia nitrogen in the circulating water was analyzed. In addition, the given site was treated by adding and using bactericidal inhibitor and the phenomenon and reason were analyzed as well. Site situation proves that the measures taken are comparatively rational, and the normal operation of system is kept well, providing reference for the relevant systems.
