Testing Alkalinity In Boiler Water - Taylor

Total alkalinity is the sum of these three forms. Alkalinity is measured by titrating a water sample with a standard acid to a designated pH and is recorded as P, M, or T alkalinity. P alkalinity is titrated with phenolphthalein to pH 8.3, M alkalinity with methyl orange indicator to pH 4.6, and T alkalinity with total alkalinity indicator to pH 4.5. Once you know the values for P, M, or T alkalinity you can use the table …

May 04, 2016 · The color changes of phenolphthalein indicator, which occurs at pH of 8.3 (P Alkalinity) and bromcresol green indicator, which occurs at pH 4.2 (Total Alkalinity) are the standard reference points for expressing alkalinity. For boilers operating up to 300 psig, the accepted alkalinity range is 200 ppm to 700 ppm, with P being 60% to 80% of Total Alkalinity.

Alkalinity. The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided.
