Jul 21, 2020 · Tri sodium Phosphate (TSP) is generally used for HP dosing. This is directly dosed into steam drum to remove carbonate & bicarbonate scale sludge & to increase pH. Phosphate reacts with calcium and magnesium forms less sticky, loose and non-adherent sludge instead of hard scale. This sludge remains in the boiler water in suspended condition and then, removed from the boiler through blow down Other than TSP, disodium phosphate (Na2HPO4) and monosodium phosphate (NaH2PO4) are used in boiler
