This reduces the alkaline (temporary) hardness. Lime/soda (soda ash) softening reduces non-alkaline (permanent) hardness by chemical reaction.

Get A QuoteHistory of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.

Get A QuoteEspecially downstream turbines are sensitive for pollutions in the steam. To avoid damages of the plant, boiler drums and all water-bearing parts have to be boiled out with alkaline chemicals before commissioning the plant. In the past conventional chemicals as trisodium phosphate, caustic soda or hydrofluoric acid were used.

Get A QuoteA steam boiler system at the most basic level can be considered as a loop. Ideally, there would be no water lost from the loop but that is highly dependent on the exact application. Because of this self-contained setup, steam is a very efficient energy carrier, it's easy to produce and control, and it's a safe option for many uses.
