Aiming at the high temperature corrosion in a coal-fired boiler

the effect of H

S and SO

on the corrosion of 12Cr1MoV under the water wall condition has been investigated by experiments. The results indicate that H

S can promote the corrosion significantly

and the coarse porous oxide film formed cannot stop the progress of corrosion. While SO

presents little effect on the corrosion. The main composition of the surface of 12Cr1MoV corrosion products is Fe

. With H

S in the atmosphere

the corrosion gradually develops into deeper layers by forming FeS

FeO and Fe

alternately. The corrosion rate is doubled for every 50℃ increase in temperature at 400-500℃.
