... Corrosion The lower furnace of a coal- or oil-fired boiler is essentially a large enclosed volume where the combustion of fossil fuel, as well as the cooling of the combustion products, takes place. The furnace enclosures are made of water-cooled tubes, generally in a welded membrane construction...

..., such as ASTM A213 grade T-9, maximum corrosion resistance requires the use of stainless steels. In oil-fired boilers, the principal source of corrosion comes from a fluxing action of molten sodium-vanadium complexes with the protective oxide scale formed on metal surfaces. Although this can occur at lower...
