The relative importance of metal oxide corrosion products in waterside deposits, as opposed to traditional scale-forming constituents, is discussed, and the sources of copper and copper oxide boiler deposits are reviewed. Also reviewed are explanations of some of the problems associated with the presence of deposits and especially, copper-containing deposits. These include those due to a reduction in heat transfer and tube metal overheating, as well as various corrosion mechanisms. Case histories, which illustrate certain deleterious mechanisms due to the presence of such deposition, are also presented.
