Why Trisodium Phosphate Dosing In Boiler Drum

Tri Sodium Phospahte Dosing In Steam Drum -

Tri Sodium Phospahte Dosing In Steam Drum - posted in Industrial Professionals: Hello everybody, Normally TSP is injected directly in steam drum and its concentration is maintained around 7 to 10 ppm in boiler blow down (in high pressure 100 bar(g) boiler). Is it not possible to inject TSP in BFW pump suction line as done with morpholene and hydrazine with maintaining same 7 to 10 ppm in BBD.
