Abstract

Oxy-fuel combustion is burning a fuel in oxygen rather than air for ease of capture of CO₂ from for reuse or sequestration. Corrosion issues associated with the environment change (replacement of much of the N₂ with CO₂ and higher sulfur levels) from air- to oxy-firing were examined. Alloys studied included model Fe-Cr alloys and commercial ferritic steels, austenitic steels, and nickel base superalloys. The corrosion behavior is described in terms of corrosion rates, scale morphologies, and scale/ash interactions for the different environmental conditions. Evidence was found for a threshold for severe attack between 10^-4 and 10^-3 atm of SO₃ at 700 C.
