Summary:There has been increasing incentive in recent years for disposal of wastes by incineration in the world. The waste materials are being considered as a supplementary energy source for existing fossil-fuel power generating stations and for industrial needs for process steam. However, the corrosion of water wall and super heater tubes ascribed to a combination of relatively high chlorine levels, high temperatures in the flue gas, and deposit formation on heat transfer surfaces has been a major problem in utilizing these materials as a source of heat energy. Design and operation aspects play an important role. The corrosion mechanisms include deposit build up, evaporation of metal chlorides, and melting of salt deposits. For Fe base alloys the formation of volatile iron chlorides, instead of protective oxide, is the main driving force, Ni base alloys being more resistant. This keynote presentation describes our current studies on the corrosion of evaporator and super heater tubes in field waste-fired incinerators, protective surface treatment via several kinds of cost-effective thermal spraying alternate materials as corrosion resistance and the condensation of Pb and Zn vapors in flue gas cooling section.
