The project aims at demonstrating the first permanent full-scale installation of the corrosion mitigation technique “Sulfur recirculation”  and simultaneously investigating the phenomenon “corrosion memory. Corrosion memory refers to “the present corrosion attack is due to historic corrosion rather than the fuel mix currently being used” . The phenomenon can be divided into two sub-areas; increased corrosion due to irreversible changes in the steel and the rate of conversion of corrosive deposits and the project will investigate both aspects. The sulfur recirculation will be installed in one of two nearly identical boilers sharing same fuel feeding system. The dynamic interplay between changes in fuel mix and corrosion attack can thus be studied effectively. The material aspect will be investigated through the aging response of the steel. The aim is to generate knowledge how precipitation occurring over time will influence corrosion.
