abstract = {In the present paper, the oxidation behavior of potentially
suitable construction materials for heat exchanging
components in coal fired power plants was studied in the
temperature range 550–700 °C. The selected materials (low
alloy steel 13CrMo44, martensitic steel P92, austenitic
steel S304HCu and Ni-base alloy 617) were exposed in a
simulated atmosphere typical for oxyfuel combustion and the
results were compared with the behavior in a test gas
simulating oxyfuel gas with addition of CO, thus simulating
locally occurring reducing operating conditions which may
happen due to incomplete combustion. The oxidation/corrosion
behavior was studied by gravimetry in combination with a
number of characterization methods such as optical
microscopy, scanning electron microscopy with energy
dispersive X-ray analysis (SEM/EDX) and glow discharge
optical emission spectroscopy (GDOES). For the low alloy
steel and P92 only minor differences in oxidation rates
between the different environments were found. For S304HCu
generally smaller corrosion rates were found in the reducing
gas, whereas for alloy 617 the effect of gas composition
depended on temperature. The obtained results are
interpreted on the basis of thermodynamic considerations
comparing equilibrium activities of the main species in the
gas atmospheres with the thermodynamic stabilities of
various possible corrosion products.},
