: : In our boiler room we use the addition of Volamine to increase pH, which we measure from a pipe containing condensate returns from the plant. We add the Volamine in the needed amounts to each operating boiler. Are there other better methods of pH control, especially how and where it is added?

: ???????????
: I think you have to measure pH in a boiler.
: Condensate return is practically distilled water with pH = 7-8, but in a boiler it must be 10-11. If it is not contaminated during processing?
: Am I wrong???
pH is controlled in the condensate returns to prevent corrosion of the piping. It is important
to control pH in both the boiler and in the condensate.
