Materials performance in simulated waste combustion environments

Combustion of waste for power generation gives increased fouling and corrosion compared to fossil fuels, and leads to higher operating and maintenance costs. New materials solutions to increase lifetime include austenitic stainless steels, nickel base alloys, coatings and weld overlaying. In this work a simulated waste incineration environment with regularly renewed deposits of KCl–ZnCl2 has been used to evaluate the performance of candidate materials and to elucidate the operative degradation mechanisms.
