Oxygen attack in boilers - Lenntech

Oxygen is highly corrosive when present in hot water. Even small concentrations can cause serious problems: iron oxide generated by the corrosion can produce iron deposits in the boiler. Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen attack is an electrochemical process that can be described by the following

Will boiling water remove oxygen from boiler water?

Yes. Boiling water will remove most, but not all, of the DISSOLVED oxygen. There will still be traces. Also (if this was a trick question) oxygen is one of the atoms in the water molecule.
