| Abstract: | Pointing to excessive dissolved oxygen in condensate water,the paper analyses the reasons,and illustrates an actual dissolved oxygen test on No.8 unit in a certain power plant to prove that condensate make-up water is a direct cause of condensate excessive dissolved oxygen.The paper also introduces several configurations of domestic condensate return water system and its make-up system,and their retrofitting schemes and results after retrofitting. |

| Keywords: | direct air-cooling unit condensate makeup water dissolved oxygen. |
