Title: Air- and Oxy-Fired Fireside Corrosion

The primary goal of this work was to examine the corrosion effects from flue gas composition changes arising from oxy-combustion. At 700°C, increased SO{sub X}, CO{sub 2}, and H{sub 2}O contents in the gas phase arising from various oxy-combustion flue gas recirculation scenarios, while maintaining constant ash deposit chemistry, do not increase corrosion in superheater or reheater tubing. At 400°C, for both oxidative and reducing conditions, the corrosion rates were lower than at 700°C.
