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?
