With burning of municipal solid waste (MSW), the potential for corrosion and tube wastage is always present. This is mainly due to certain corrosive substances in the refuse and some of its other constituents. There are two approaches to corrosion control, either prevention by conservative design, or by utilization of corrosion resistant materials. This paper will describe both of these corrosion control methods, with specific emphasis on application and experience. Both mass-burn and refuse-derived-fuel (RDF) systems will be addressed.
