Steam Boiler: What is Alkalinity?

The amount of CO 2 produced is proportional to alkalinity. Because of an alkalinity that delivers twice as much CO 2 formed from HCO 3-by CO 3 2-due to interference of bicarbonate is the sum of reactions above. Carbonic acid is usually neutralized with chemical treatment at each steam directly or indirectly through boiler to produce pH around 8.5 to 9.0.
