Chemistry guidelines for cycling service of fossil power plants

Many of the existing fossil-fired utility boilers in the U.S. are going into the cycling mode of operation (load cycling, on-off cycling, etc.). Corrosion protection for the pressure part components of these boilers relies on the proper control of the waterside environment, which has greater demands put upon it by the cycling mode of operation than the base loaded operation. Specific recommendations are made to minimize out-of-service corrosion, operational dissolved oxygen attack, and corrosion product transport.
