The Study on the Marine Deaerator

As the makeup water entering the boiler feed water cycle usually contains corrosive gases, particularly oxygen and carbon dioxide, so the corrosive gases should be eliminated by a deaerator. While the other domestic companies have made a deaerator for land industrial field, our company has developed and is able to produce a spray & scrubber type deaerator for marine to maintain below the level of 7ppb of dissolved oxygen in the condensate. In this paper, we describe the principle, design technique and experimntal results of the spray & scrubber type deaerator.
