High temperature corrosion memory in a waste fired boiler – Influence of sulfur
Artikel i vetenskaplig tidskrift, 2021

The selection of fuel for a Combined Heat and Power (CHP) plant can vary over time. By choosing less expensive fuels, operation costs are reduced, however, cheaper fuels generally increase corrosion maintenance costs. The corrosiveness of different fuels has been studied extensively while how the current corrosion attack is influenced by corrosion history, i.e. previous deposit build-up and oxide scale formation, is less studied. This phenomenon may be referred to as a “corrosion memory” effect (Paz et al., 2017). The present work investigates the influence of addition of sulfur to the fuel on the corrosion memory through air-cooled probes in the Waste-to Energy lines at Måbjerg Energy Center (MEC) in Denmark. The results show a corrosion memory effect, i.e. as initially corrosive environment may increase the subsequent corrosion rate and vice versa.
