In Reply to: low ph of condensate return posted by zaib on May 28, 2001 at 03:29:54:
: we are operating 3 ton / h 350 psi water tube boiler. we are producing about 40 tons steam/day. our make-up water is zeolite treated we have also adopted internal treatment.but ph valu comes upto 4 or 5 . what may be wrong?
: moreover continuous blowdown remains open constantaly.
: but waterside of boiler has a layer of scale .is our treatment is faulty or what is reason?
: what chemicals& in what quantity will be needed to raise ph value of condensate?
: Vern layed it all out for you, but I would add if you have just adopted internal treatment, why is your continuos blowdown open all the time? Are you giving the chemicals a chance to work? Or are you blowing them out as fast as you put them in?
