What is M alkalinity in boiler water? – Restaurantnorman.com

2019/7/31 · What is M alkalinity in boiler water? 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.

Boiler Water Treatment Guidelines; Columbia Boiler Co - Columbia Boiler Co - Low Pressure, High Pressure Boilers

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. Values higher than this can lead to
