Electrochemical corrosion rate probes have been constructed and tested along with mass loss coupons in an air plus water vapor and a N2/O2/CO2 plus water vapor environment. Temperatures ranged from 200? to 700?C. Results show that electrochemical corrosion rates for ash-covered mild steel are a function of time, temperature and process environment. Correlation between the electrochemical and mass loss corrosion rates was poor.
