The complex and corrosive nature of the incineration environment coupled with high temperatures can lead to premature failure of various metallic components in an incinerator. Specifying materials solely for service in non-corrosive, high-temperature environments is somewhat straight forward and well understood. However, the effects of corrosion on the alloy’s properties and its subsequent life expectancy is not well known and difficult to predict. The importance of appropriate material selection, failure analysis, fabrication technique and process control are illustrated by discussion of a case history involving an incinerator chute.
