Water Handbook -Boiler Deposits: Occurrence And …

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).
