An Introduction to Treatment of Steam Boiler WaterFigure 1.2). Water tube boilers are used in high-pressure and very-high-pressure applications. Most military installations have a central boiler plant containing water tube boilers in addition to fire tube boilers that are located in, and serve, individual buildings.High-Pressure Boilers: Types, Working, Advantages, …Most high-pressure industrial boilers with high purity feedwater use a phosphate-based chemical treatment program for corrosion control. The evolution ofphosphate-based boiler chemistriesfollowed improvements in feedwater quality. Prior to the advent of demineralizers, sodium phosphates were used to precipitate calcium to a calcium hydroxyapatite that was a fluid sludge removable by lower drum blowdown. When demineralized water systems came about, the need for hardness precipitation was replaced by a need for phosphate buffering. The buffering action of the phosphate treatment will minimize the potential for acid and caustic based corrosion. Keeping a clean heat transfer surface is key to minimizing under-deposit corrosion cells. Deposit minimization relies on both the feedwater treatment and polymeric dispersants. Besides causing boiler tube overheat failures, deposits play a role in corrosion. Formation of concentration cells under and within deposits can lead to corrosive conditions at the tube metal surface. As such, the maintenance of clean boiler …
