Carbon dioxide (CO2) dissolved in boiler condensate is the principal cause of corrosion in condensate return lines and condensate storage chambers. Carbonic acid (H2CO3) is responsible for costly repairs and replacement of equipment, as well as unscheduled shutdown of steam-generating systems. The primary source of this corrodant is carbonate and bicarbonate alkalinity entering the boiler in the makeup water stream.
