What Is P Alkalinity In Boiler Water

Diference between P Alkalinity T Alkalinity and M Alkalinity

>Total alkalinity or T alkalinity is the measurement of all species of alkalinity in the water. > It is the final endpoint for the alkalinity titration. >The concentration of each of the three species can be determined by titrating a water sample with acid of a known concentration and using chemical indicators, phenolphthalein (P indicator),methyl orange (M indicator), or a pH meter to

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

Difference Between p Alkalinity and m Alkalinity | …

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.
