Abstract
General accumulation of iron oxide and copper oxide or copper on boiler surfaces during service is almost always due to corrosion by water in the preboiler system beginning at the point where steam first condenses. The reduction of this corrosion will result in cleaner boilers and permit longer operation of the boilers between cleanings. This paper reports progress made in reducing iron and copper corrosion using ammonia, cyclohexylamine, morpholine, and sodium sulphite. The work was done at the Southern California Edison Company steam plants. This company supplies electric power to a large portion of Southern California by means of its hydroinstallations and its four steam plants. The reduction of corrosion in the condensate system at the Long Beach Steam Station and at the Redondo Steam Station is discussed.
