Why is phosphate dosing done in a boiler? - Quora

The first way is that phosphate can be used to precipitate hardness. Scaling in a boiler is generally not desirable because it hurts fuel efficiency and can also lead to tube failures from overheating but calcium phosphate is preferred to calcium carbonate because it is a softer scale that is less likely to for ma hard coating on the tubes.

using of congruent phosphate as equilibrium phosphate

Using of congruent phosphate as equilibrium phosphate

If insufficient boiler water alkalinity is maintained, magnesium can combine with phosphate, magnesium phosphate formed has a surface charge that can cause it to adhere to boilers tube surfaces and then collect other solids. For this reason, alkalinity is an important part of a phosphate precipitation program. 3 Congruent phosphate treatment

inexplicable ph drop in boiler blowdown water

Inexplicable pH drop in boiler blowdown water

What I feel is that boiler pH can get down with entrance of exhaust in the boiler water as it totally contains CO & CO2; they can create carbonic acid which can contribute these amount of pH drop. So, better you check your exhaust gas lines whether there is any leakage which is allowing exhaust gas to enter into water.

Waste Heat Boiler - an overview | ScienceDirect Topics

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
