: What problems could one expect, if they used a system that injects chemicals (caustic, phosphate, sludge) into the feed water line that is supplying 3 boilers that operate at 200PSI?
: Most of the time 2 boilers are running, and the third is rotated in and out with the other two, so that at all times, at least to boilers are running. Load varies from 80 - 125Kpph.
: There is much more to this, but I am curious as to what you all think.
Another set up that I am used to is puting Sulphite and Amine into the D/A and piping the phosphate to be injected right into the steam drum of each boiler. Of coure this requires high pressure phosphate pumps which have a cost associated with it.
