Some Relations Between Deposition And Corrosion Contamination In Low Make-Up Systems for Steam Power Plants Available to Purchase

A mechanism is postulated which indicates that the ratios and interactions of contaminants in low make-up systems of steam power plants are more significant with respect to deposition than the absolute amount of contaminants present. Three examples are cited in support of this theory. It is shown that mechanisms based upon the thermodynamics of the soluble ions from the corrosion of materials of construction can qualitatively account for both the form and composition of the deposits from high purity water in large steam generating stations. In so far as trouble from deposits is concerned, the ratio of copper to iron seems more important than the absolute concentrations of either. Small variations in the concentration of other ions do not seem to be of any great importance. 3.4.3
