Scale deposition on heat transfer surfaces can seriously affect steam generation in modern boilers. Deposits can lead to a loss of efficiency serious corrosion short and long term overheating problems and ultimately tube failures. Plant profitability and production losses generally cannot be recovered when tube failures occur. Production losses resulting from reduced steam capacity are far greater than the actual repair and maintenance costs incurred during the shutdown. The major problems associated with deposits and scale are corrosion and overheating. Control ofiron oxide deposits by using specific polymers is key to maintaining clean heat transfer surfaces and generating passive films within an industrial boiler. This paper will focus on mechanisms that jusitfy this application.

Key Words: Coordinated Phosphate, Corrosion, Complexation, Dispersion, Polymers
