High Sodium/phosphate Ratio In RG Boilers - Chemical

May 01, 1992 · Utility chemists usually try to maintain sodium to phosphate ratios within a narrow range 2.3/2.6 to 1. This range provides the best buffering capabilities without exposing the boiler tube metal to acidic or caustic corrosion.

Phosphate hideout becomes evident in load swings or start-ups with changing heat input. As the load is increased, the pH increases with the decreasing phosphate. When the load is reduced, the pH decreases and the phosphate increases, without chemical additions to the boiler. Figure 1 — Normal congruent phosphate-pH boiler chemistry.

Apr 25, 1999 · The coordinated phosphate approach is to maintain a chemistry in the bulk boiler water. The chemistry is to maintain a septic sodium to phosphate molar ratio so as to prevent extremes of pH from developing under deposits where bulk water dissolved solids can concentrate by factors in excess of 10,000 to one.

Acid Phosphate Corrosion | Structural Integrity Materials

Boiler Treatment Chemicals. The primary objectives in boiler design, operation and effective treatment include: efficiency in heat transfer, minimisation of energy usage, production of pure steam and safe, reliable operation. The problems encountered in steam-raising plant can be severe if scale formation and corrosion are allowed to occur.

Boiler Water Treatment - AWT

However, it contributes to deposit buildup on a par with other contaminants. Analyses of typical boiler deposits show that magnesium silicate is present in roughly the same ratio to calcium phosphate as magnesium is to calcium in boiler feedwater. Phosphate/Polymer Control.
