Boiler Water Treatment Agent (Q716)

Q716 is a liquid compound containing a phosphorous boiler water treatment agent with alkalizing agents, corrosion inhibitors, passivators, and dispersants. This product is used to control boiler corrosion, scaling, and deposition, and is suitable for high, medium, and low-pressure steam boilers. It is injected into the system at low-pressure points in the boiler feedwater pipeline where thorough mixing is easy. Q716 prevents corrosion, scaling, and deposition through pH adjustment, metal surface adsorption, and dispersion stabilization.

3. Usage Method

  Dosage Point: Before the boiler feedwater pump.
  Dosage Amount: The dosage amount depends on several factors, including the quality of the makeup water, thermal deoxygenation, boiler concentration multiple, and variations in evaporation load. The typical dosage range is 5-20 mg/l, adjusted according to the total phosphorus control indicators and boiler operating conditions as per high, medium, and low-pressure boiler standards.
  Dilution: Can be added directly in concentrated form or diluted before addition.
