The composition of the flue gases from refuse incinerators varies widely because of the nonhomogeneity of the feed. There is general agreement among investigators that wet scrubber corrosion of metallic parts is an extremely severe problem. The rapid attack of most metals and alloys is predicted when one analyzes the effluent and observes significant quantities of HCl, SO2, SO3 trace HF and organic acids. To complex the problem, metallic surfaces are rapidly coated with very adherent deposits of oxides and sulfates which can both partially protect the surface but more significantly create severe pitting and crevice corrosion attack by the concentration of acid chlorides in the system near the metal surface at the coating defects.
