In this method, no free caustic is maintained in the boiler water. Figure 11.14 shows resulting pH versus phosphate concentration, the resulting pH on addition of trisodium phosphate. Trisodium phosphate hydrolyzes to produce hydroxide ions. Phosphate acts as

The proportioning concentration is 0.3-0.5% of sodium hydroxide and 0.5-1% of trisodium phosphate. When used it for boiler cleaning, increase the pressure to half of the rated pressure slowly, and cook at high water level for 24 to 48 hours, then let the lye out. Rinse the boiler with clean water until the pH value of the effluent is less than 9.

Introduction: Trisodium phosphate (TSP) is an inorganic salt used as industrial detergents, metal treatment and in toilet floor cleaners. TSP is pure cleaning power. Used as a water softener; for the treatment of boiler water; as a paint remover; in photographic developers; for tanning leather; for manufacturing paper; for clarifying sugar.Also, it is a common laboratory reagent.
