May 02, 2000 · Calcium, for instance, reacts with phosphate at the proper pH to form hydroxyapatite, a harmless precipitate sludge (when dispersed) that falls to the bottom of the boiler where it can be removed through bottom blow down. When boiler water pH is not within the proper range, calcium reacts with phosphate to form harmful calcium phosphate scale

Boiler – Fundamentals and Best Practices

Calcium phosphate is virtually insoluble in boiler water. Even small levels of phosphate can be maintained to ensure the precipitation of calcium phosphate in the bulk boiler water-away from heating surfaces. Therefore, the introduction of phosphate treatment eliminated the problem of calcium …

Jun 26, 2017 · "H" and "M" values are determined as calcium carbonate from feed water analysis. Example: Field tests on a given feedwater show H = 84 ppm and M = 59 ppm. Non-carbonate hardness (H-M) = 25 ppm as CaCO 3. Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm.

Apr 05, 2020 · At 40 °C, its solubility is 1,551 ppm; at 100 °C, which is the normal boiling point of water, its solubility decreases to 1,246 ppm, and at 220 °C it falls to 40 ppm. Calcium Sulphate reacts at high-temperature surfaces essentially in the same manner as Calcium Carbonate and with the same effects and consequences.

Boiler Water Treatment Guidelines; Columbia Boiler Co

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 embrittlement of the steel. Phosphates. Phosphates are used to react with …
