injection of phosphate to drum boiler

disadvantages of trisodium phosphate dosing in high …

In short when hardness is seen in boiler drum water, phosphate dosing is recommended. Typically phosphate dosing causes hardness causing elements to precipitate at the bottom of the drum from where they are discharged along with blow down. Other compounds of phosphates are also used to control silica, pH levels etc.
