Which can provide a boiler water softener - the use of trisodium phosphate dosing instructions

Boiler feed water should be added trisodium phosphate, because the boiler water in boiling conditions, the PH value of 9 ~ 10.5, trisodium phosphate can adjust the PH value. Boiler operation requirements, water phosphate - a certain amount of excess, excess is too small, poor anti-scaling effect, the excess is too large, will cause the rise in drug consumption, the furnace water salt content increases, the formation of magnesium phosphate scale and phosphate "hidden" phenomenon, medium pressure boilers are generally controlled at 5-15mg / L.
