Coating solutions for waste and biomass boilers


Customers: Turku Energia and Ekokem


Difficult fuels cause demanding corrosion conditions in waste and biomass fired boilers, which leads to corrosion damage and expensive replacements.


Development and manufacturing of dense, protective thermal spray coatings on the boiler tubes to prevent corrosion damage. Performance of several coating types (HVOF, arc spray and fused) was validated in Turku Energia and Ekokem plants.


On-site experiments have demonstrated that coatings promise to significantly improve the life of boiler tubes under corrosive/erosive service.
