The sulfidation behavior was investigated of two kinds of the preoxidized Fe-13Cr and Fe-18Cr-3Al alloys for the water wall tubes in oil firing boilers. A McBain balance assembly and CCD sensor were used to determine a sulfidation rate in 1.92% H2S-H2 atmosphere. The oxide scale formed on the preoxidized Fe-13Cr alloy was effective to prevent the sulfidation attack at 973K, although it was hardly effective above 873K. On the other hand, the oxide scale on Fe-18Cr-3Al alloy showed remarkable retardation effect on the sulfidation attack at 973K to 1073K. It is concluded that the difference of sulfidation behavior of those preoxidized alloys is attributed to the difference of the scale formation mechanism. The scale on the Fe-13Cr alloy was composed of Cr2O3 and Fe2O3 which was subsequently sulfidized. On the contrary the scale on the Fe-18Cr-3Al alloy was formed mainly with fine Cr2O3 layer which is capable to prevent the sulfidation attack.
