Marine Boiler [Part 3], Boiler Water Contaminants.

All waters , whether they are fresh water or sea water, contain chemicals that can cause operational problems and damage to the boiler.

Marine boiler feed water contaminants are, calcium bicarbonate, sodium chloride, magnesium chloride, magnesium sulphate, calcium sulphate, silicate, copper, iron, carbon dioxide, oxygen, hydrogen. Temporary and permanent hardness, total hardness. Effects of impure boiler feed water.
