Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · The desired alkalinity in the boiler is 400 ppm "M" alkalinity. The boiler operates at 20 cycles of concentration. What is the required dosage of caustic soda when purchased as a 50% liquid solution. The total alkalinity required in the feedwater is 400 ppm divided by 20 cycles of concentration = 20 ppm.

Testing Alkalinity In Boiler Water - Taylor

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 p henolphthalein to pH 8.3, M alkalinity with m ethyl orange indicator to pH 4.6, and T alkalinity with t otal alkalinity indicator to pH 4.5.

The relative alkalinity is determined by the formula: The number 40 in the formula (1) indicates that it is assumed that only phenolphthalein alkalinity exists in the boiler, i.e. all sodium bicarbonate contained in the source water turns into sodium hydrate under the conditions of removing of carbon dioxide with steam in the boiler according to equation (2). 2NaHCO 3-> Na 2 CO 3 +CO 2 gas +Н 2 О->2NaOH+CO 2 …
