Observations have been made for 40 years or so on the formation of iron sulfide (FeS) during corrosion and wastage of furnace tubes in coal fired boilers.1,2,3 The usual explanation is that, in large part, the iron sulfide comes from the pyrites in the coal which falls unburned to the hopper slopes. Pyrites provide substantial amounts of FeS in the corrosion deposit and tube wastage by reacting with the tube metal
