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.

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.

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

Boiler Water Quality Control - Complete Water Solutions
The increasing level of the TDS is known as "cycles of concentration.". This term is used very often in the operation and control of a boiler system. A water supply that contains 175 ppm of TDS in the make-up water could be concentrated 20 times to 3500 ppm. The maximum amount of TDS allowed in a low-pressure boiler is 3500 ppm.
Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm). A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi.
