Supplemental Oxygen for All-Volatile Treatment under Oxidizing Conditions

ABSTRACT

With aging fleets of fossil- and gas-fired units throughout the industry, flow-accelerated corrosion failures remain a major concern. Southern Company's water chemistry program strives to provide its fossil and gas fleet with the best innovative solutions to control water/steam cycle chemistry within the latest industry guidance. This paper explains the Southern Company Water Chemistry group's approach to achieving and maintaining the best control over the condensate and feedwater dissolved oxygen concentration for all-volatile treatment under oxidizing conditions (AVT(O)) chemistry programs.
