This is part of a 12-volume set. Volume E covers chemistry and metallurgy including: corrosion - feed and boiler water; plant cleaning and inspection; non-ferrous metals and alloys; non-metallic materials; and welding processes. This volume deals with the pre-combustion treatment of the fossil fuels which fire the boilers and the control of the feed and boiler water which constitute the working fluid. The control of cooling water quality and the techniques of plant cleaning, both before and after commissioning and during overhauls, are also covered in the chemistry section. In the metallurgy section topics dealt with include defect analysis and life assessment, materials behaviour and life assessment, materials behaviour and selection welding processes, non-destructive testing and environmental effects.
