Using Air and Acid to Quickly Get Perfect pH/Alkalinity

When the pH is a little low (about 7.1 or 7.2) and the total alkalinity is near recommended levels, adding soda ash will bring both up to proper levels. However, if pH is low and total alkalinity is OK, there has not been a practical way to raise only the pH. Yo-Yo Effect

How much Sodium Hydroxide needed to raise boiler water pH

In addition to pH, total alkalinity also needs to be acceptable, the range I have seen in the literature for a hot water low pressure boiler is between 140-700 ppm. I would not get hung up over a "supposed to" single pH. Talk to your boiler dealer/mfr and follow its recommendations.

Don't Confuse pH With Alkalinity | Ask The Water Doctor

Just raising the pH with an alkaline filter does not, in itself, raise the alkalinity. Water with high alkalinity may be beneficial in some circumstances to the body, but raising the pH serves no function whatsoever. IT IS NOT ALKALINE WATER THAT YOU NEED, IT IS WATER WITH ALKALINITY! If your bodies pH is not between 7.35 and 7.45

Water Handbook - Preboiler & Industrial Boiler Corrosion

Conversely, addition of trisodium phosphate adds caustic, increasing boiler water pH: Even if the original makeup or feedwater pH is not low, feedwater can become acidic from contamination of the system. This method should not be used for boilers equipped with nondrainable superheaters. Cold Weather Storage.

Boiler Water Tests | Viking Water Technology, Inc.

For boilers up to 300 psig, the accepted limit for total dissolved solids (measured gravimetrically, not conductimetrically) is 3500 ppm. values below 7 indicate increasing acidity and those from 7 to 14 indicate increasing basicity. Since the pH scale is logarithmic, each change in pH value by a whole unit indicates a 10-fold increase in

Boiler Efficiency and Steam Quality: The Challenge of

Control steam usage to ensure that steam demand does not exceed boiler capacity. Control changes in steam usage to ensure that rapid changes in steam demand will not reduce steam quality. To affect either of the above, use modulating versus on-off valves at steam-use points. Add boiler feedwater with modulating versus on-off controls.

R- RH- and RHC-Steam Boiler Models (RB-Series) Serial No

R, RH and RHC steam boiler models require four (4) gallons of feed water per hour for each 10 kW of electric heating capacity of the boiler. Lines should be of adequate size and meet local plumbing codes. All boilers must be blown down periodically to remove minerals, scale and other foreign matter, which accumulate inside the pressure vessel.
