In continuous operation of a boiler, it becomes quite difficult to maintain the metal tube surfaces clean, without any layer formation. Depending upon the chemistry of the feed water, different types of scales or deposits develop on the boiler tubes which affect the heat transfer taking place in …Get Price
Boiler water can permeate the porous deposit resulting in localize corrosion. When it is coupled with significant heat flux, concentration of the boiler water occurs rapidly speeding the corrosion. The corrosion action is a result of the formation of caustic-ferritic compounds through the dissolving of the protective magnetite film.Get Price
