Oxide scale growth and presumed exfoliation in a 700°C or higher steam condition: A simulation study for future operations of ultra-supercritical power plants

New insights into the oxidation mechanisms of a Ferritic-Martensitic steel in high-temperature steam

“…To reduce carbon emissions, it is desirable to improve the efficiency of the steam-generating power plants by increasing the operating steam temperature and pressure, such as in the ultra-supercritical coal-fired power plants [7,8] and supercritical water-cooled nuclear reactors [9][10][11]. With the increase of operating temperatures (>600 ºC), the growth of oxide film on the F-M steels is significantly enhanced [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The consequences of the thickening and failure of the surface oxides are of increasing concern in these steam-generating power plants.…”

Experimental and thermodynamic investigations on the chlorine-induced corrosion of HVOF thermal sprayed NiAl coatings and 304 stainless steels at 700 °C

“…the European AD700 program, the American A-USC (760°C), and the Japanese A-USC, etc.) [4]. This increasingly harsh environment, however, limits the selection of materials to high-alloy steels and nickel-based alloys that could provide sufficient creep and fireside corrosion resistance [5].…”

Numerical simulation of the failure behavior of steam‐side oxide scale considering oxide creep and physical defects

“…The steam flows in the tubes and simultaneously absorbs energy from the outside high temperature flue gas. Due to the inhomogeneous thermal load of the tube, the growth rate and physical defect length of oxide scale vary along the hoop direction . For simplicity, both the geometry and thermal load are assumed to be axisymmetric in this paper.…”
