Components of a high pressure boiler system which are in contact with high purity water are described. Materials of construction and operating pressures and temperatures are given for such items as condensers, feedwater heaters and boiler components. Demineralized and evaporated make-up are referred to along with data on the chemical nature of the water. Analyses of water and steam samples from points in the boiler water cycle show iron and copper contents and other indications of the purity and corrosiveness of the water. The part played by chemical treatment, boiler blowdown, removal of dissolved gases and other operating factors in maintaining the described water conditions are discussed. 4.6.2
