of boilers water is based on reaction of di-sodium and mono-sodium phosphate with free hydroxide generated by tri-sodium phosphate as shown in equations (1, 2 and 3) to form tri-sodium phosphate.

It can take two forms: caustic gouging or caustic cracking, also called caustic embrittlement. Caustic attack or caustic corrosion, is often encountered in phosphate treated boilers in which deposits of phosphates or other 'scale' occur in high heat transfer areas. Boiler water can permeate the porous deposit resulting in localize corrosion.

concentration of phosphate in the bulk boiler water can decrease with increasing load and pressure, and then return to the original levels on subsequent load or pressure reductions. This phenomenon, known as "phosphate hideout," can make it difficult to maintain close control of …

Hartford Steam Boiler Boiler Water Treatment Phosphate compounds are common additives for boiler water treatment. Phosphate compounds react with any remaining hard water compounds to create a soft sludge that is eliminated through blowdown. Trisodium phosphate is the most common compound for lower pressure boilers. Phosphates also

The Function of Tri sodium Phosphate dosing in Boiler water is to condition feed water to ensure that plant involved in the steam / water cycle is kept free from corrosion. Tri – sodium phosphate solution is to be dosed in Boiler Drum / HRSG Drums to maintain water PH, to minimize potential acid and caustic corrosion in the drums.
