.... Waterwall 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...
