The reducing environment produced by oxygen scavengers initiates and propagates flow-accelerated corrosion (FAC) in the feedwater system and other components of high-pressure steam generators, including heat recovery steam generators (HRSGs). Since 1986, FAC-induced attack has caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for many new power plants both domestically and globally, and in which the condensate/feedwater system contains no copper alloys, continue to call for oxygen scavenger feed to the condensate. This document is a response to this misguided trend.
