锅炉（给）水脱氧技术研究的进展

In this article the mechanism of oxygen induced corrosion and the factors having effect on corrosion of boller steel during service were introduced. The principle and progress of water deoxygenating methods currently were reviewed with analysis of their disadvantage and disadvantage. Among others, Hl-GEE is a new technology, because of its simple principle, convenient manipulation, low investment and high efficiency, HIGEE has good prospect.
