Abstract. Four boiler water treatment programs were evaluated for their ability to transport metal ions through 600 psi (41 MPa) waste heat recovery steam generators. Phosphate/sulfite alone failed to transport Ca, Mg, or Fe metal ions through the boiler. The addition of a polymer to the phosphate/sulfite transported Mg through the boiler and aided in the dissolution of Mg from …
