Corrosion Resistance of Alloys in IGCC Environment
IGCC recovery boiler materials are subject to severe corrosion in environments composed of a gas mixture (CO-H 2 -H 2 O-CO 2 -H 2 S) and vanadium-containing fly-ash resulting from the combustion of oil residues. This paper presents a study of the corrosion behaviour of two Fe-Ni-Cr austenitic alloys in a typical IGCC environment at 400°C. The alloy composition influences the vanadium incorporated in the corrosion scales during the test, which affects the scale growth process. The valence state (determined by micro-XANES) and the amount of the incorporated vanadium is modified by a subsequent air flow at 400°C.
