The prevention of oxygen corrosion is vital for the integrity of steam raising plant. In recent years many new oxygen scavengers have been introduced to the market with a view to avoiding the toxicity problems associated with hydrazine.

The oxidation and degradation products of these new oxygen scavengers is a subject of special interest to plant operators. This paper explores in detail the reaction products generated from diethylhydroxylamine, a volatile oxygen scavenger, and discusses their relevance to plant operation. Results are presented from laboratory studies on an experimental boiler and further supported by data generated in the field. These studies show that enhanced corrosion protection can be achieved with diethylhydroxylamine compared to results obtained with hydrazine, especially within condensate systems.
