Abstract
Depending on the chemical make-up of the waste stream and operational parameters, a variety of high temperature corrosive environments are generated in the incinerator. As corrosion of industrial equipments is essentially due to high content of sulfur and chlorine in the combustion gas, this study is focused on the interpretation of degradations of pure iron in experimental air environment containing 1000 ppm of HCl and 100 ppm of SO2. Thermochemical calculations were used to estimate the role of these corrosive elements considering chemical potential diagrams and stability paths in pseudo-binary diagrams involving iron and the corrosive atmosphere. The influence of chlorine has been described by the “active corrosion” mechanism proposed by Grabke and confirmed by our calculations. The role of sulfur has been pointed by its “cycle” leading to the formation of eutectic metallic tri-sulfates, promoting a liquid phase corrosion type in the range of the industrial temperatures.
