Lowering Costs by Improving Efficiencies in Biomass Fueled Boilers: New Materials and Coatings to Reduce Corrosion

As the world moves to alternatives to fossil fuel solutions, the number of power plant boilers combusting biomass is growing. However, a serious problem that biomass plants face is severe corrosion of the boilers. The EU-funded BELENUS project will take a holistic approach to solve this issue. Surface engineering methods will optimise material performance, new welding methods for the coated tubes will improve the quality of boiler components, and an online corrosion monitoring will help evaluate corrosion conditions. The ultimate aim is to enhance biomass conversion efficiency and increase the lifetime of the biomass plant. If successful, the project estimates to lower bioenergy capital and operational expenditures by 5 % and 60 % respectively.
