It provides better protection for the boilers, turbines, heat exchangers, and steam piping from scale, corrosion, and deposits while using more condensate return water. Treating condensate return water requires less acid and caustic to regenerate compared to treating raw water. It reduces the amount of demineralized makeup water utilized.

Why is steam condensate corrosive? – Akvante

2017/10/22 · This free carbon dioxide gas (CO 2 ) is volatile and leaves the boiler with the steam and reacts with condensed water to form carbonic acid. Carbonic acid is a weak acid, but as the condensate water is pure, this weak acid reduces the pH significantly, often in the range of 5-6. At this low pH, the condensate water is very corrosive to carbon
