Boiler feed water treatment in energy generation
Depending on the method used, water is heated in various ways and converted into steam within the core process of a power plant. Corrosion processes are significantly accelerated under these predominant conditions, meaning the corrosion protection is of fundamental importance.
The boiler feed water is treated to remove soluble salts in upstream process stages by means of ion exchangers or reverse osmosis systems. Subsequently, soluble gasses are removed, especially oxygen and carbon dioxide.
Various chemical additives are metered in depending on the boiler type, chemical mode of operation and residual salt content. The pallet ranges from oxygen binders and corrosion inhibitors to sodium hydroxide solution, crude ammonia liquor or hydrazine for pH value correction.
