The nature of the scale formed depends on the chemical composition of the concentrated water. Normal deposit constituents are calcium, magnesium, silica, aluminum, iron, and (in some cases) sodium. The exact combinations in which they exist vary from boiler to boiler, and from location to location within a boiler (Table 12-1).

The Effects of Corrosion in a Boiler | Chardon Labs

Another cause of corrosion can happen when untreated condensate returns to the system, bringing dissolved iron and copper oxides with it back into the boiler. To prevent this type of corrosion, plants often use volatile amines in the form of either neutralizing or filming treatments, which prevent contaminants in condensate from producing damage.
