In Reply to: pH control, methods of chemical addition. posted by Tom on July 23, 2002 at 16:38:23:
: 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?
Each situation is different, but generally speaking adding condensate corrosion inhibitor is best done by injection into
the steam line. Adding to the boilers is okay, but you experience more loss of the product through blowdown that way. How do you
like the volamine? That is the solid product you are using, correct?
