Low Alkalinity In Boiler Water
Low Alkalinity In Boiler Water
Boiler Water Treatment Guidelines; Columbia Boiler Co
Maximum and minimum P alkalinity and OH Alkalinity values (and/or pH) limits are specified for proper control of boiler water alkalinity in your plant. Alkalinity concentrations below the specified minimum may result in corrosion difficulties or the formation of objectionable sludge or scale. Whenever boiler water alkalinities fall below the recommended minimum, do not hesitate to increase the feed of alkali (caustic products as NaOH or KOH) or to increase the total alkalinity of the treated water if a softener is involved. Alkalinities above the specified maximum may result in foam-type carry over or localized caustic embrittlement corrosion, and they may complicate protective measures employed to prevent caustic embrittlement. When boiler water alkalinities rise above the recommended maximum, reduce the feed of alkali bearing materials or reduce the total alkalinity of the treated water if a softener is used. In an emergency, increase the blow down rate if necessary to bring boiler water alkalinity …

Steam Boiler: What is Alkalinity?
Steam boiler low alkalinity Alkalinity in the boiler, as well as minimising corrosion, also acts as a scale salts precipitant. As an example caustic alkalinity in the boiler will precipitate magnesium salts to form a mobile sludge that can be easily removed by blowdown, e.g. MgCl 2 + 2NaOH >> Mg (OH) 2 + 2NaCl

ALKALINITY CONTROL is characterized as a safe food additive in accordance with U.S. regulations FDA (CFR code 173.310 Boiler Water Additives). Application ALKALINITY CONTROL is used for all boiler pressures mainly for providing the required alkaline conditions within the boiler for corrosion control, by neutralization of acid gases and by the establishment of passivating layer (magnetite).

pH - As previously indicated, water PH should be maintained between 9.5-11.5 PH inside the boiler (boiler alkalinity). Chlorides - The indicated limit here is a max. 50 ppm. More specifically chloride levels of the cooling water should be on the low end, as sudden or gradual increases in temperature could indicate sea water contamination.

Alkalinity is the water defenses against acidification. In natural water, alkalinity mostly due to the presence of bicarbonate and the remaining is caused by carbonate and hydroxide. Some levels of alkalinity content are required in boiler water, so the complete removal of alkalinity in the boiler is rare to be performed except in demineralization treatment.

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.
