The importance of pH in steam-boiler water

Jun 24, 2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good. Hold that thought for a moment.

Boiler Corrosion Inhibitors | ChemTreat, Inc.

Alkalinity Builders. Effective boiler water treatment requires the maintenance of proper levels of boiler water alkalinity in low- and medium-pressure boilers to reduce corrosion. The proper alkalinity level also provides sufficient hydroxide for the preferred reactions between calcium and phosphate, and magnesium with silica.

Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

Boiler Alkalinity Chemical

Boiler Alkalinity. Boiler Alkalinity chemicals are used to increase the boiler water pH within the boiler water. The mild steel boiler tubes prefer higher pH waters. Increasing the boiler pH may reduce corrosion rates, allow the polymer to activate, and minimize silica scaling. ChemWorld stocks 25% and 50% of alkalinity solutions.

Because of an alkalinity that delivers twice as much CO2 formed from HCO3- by CO32- 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. Reduction of alkalinity in the boiler feed water is necessary to minimize the formation of CO2 and …
