Phosphate Polymer Treatment for Steam Boilers

Phosphate Polymer Treatment for Steam Boilers

Accepta 2814 is a high performance phosphate polymer based treatment product scientifically formulated for use in steam boilers.

Accepta 2814 is a blended liquid treatment of polymers and is an ideal treatment for high pressure steam boilers using softened make-up water.

Accepta 2814 is effective against iron and phosphate sludges. The organic polymer provides transport of the calcium, magnesium, iron, phosphate and silica through the boiler.

The formation of adherant deposits is prevented, thus increasing the steam production runs, reducing the danger of tube overheating

Product Benefits

  • High performance polymer for use in steam boilers.
  • Excellent treatment for high pressure steam boilers.
  • Effective against iron and phosphate sludges.
  • Increases steam production runs.
  • Reduces danger of tube overheating.

*Full details of the product properties are available in the Safety Data Sheet. See below.

Application & Dosage Information

For Water Tube Boilers

Dosage (ppm) = (Feed water hardness x F) + (Feed water iron x 20)        

  • Use factor ‘F’ 23 for boilers up to 35bar
  • Factor ‘F’ 24 for boilers 35-40bar
  • Factor ‘F’26 for boilers 41-44bar
  • Above 44bar use an extra Factor of 1 per 3bar boiler pressure

Control product on phosphate reserve in accordance with BS2486 1997.

  • 0-20bar (Phosphate range 30-70ppm)
  • 21-40 bar (phosphate range 20-50ppm)
  • 41-60bar (phosphate range 20-40ppm)
  • 61-70bar (Phosphate range 15-30ppm)
  • Maximum 70 bar pressure for product

For Shell Boilers

Dosage (ppm) = (Feed water hardness x F) + (Feed water iron x 20).

  • Use Factor ‘F’23 for boiler up to 30bar

Control product on phosphate reserve in accordance with BS2486 1997.

Phosphate range in accordance with the Heat Flux for boiler up to 30bar.

  • Heat flux kW/m2 <300 control phosphate 30-60ppm
  • Heat Flux >300 control phosphate 10-30ppm

Note: Dose Accepta 2814 proportional to the boiler feed water before the boiler feed pump.

Use Accepta 2814 neat and do not mix with amines or oxygen scavengers.

It is always advisable to carry out a 'Control Of Substances Hazardous to Health' (COSHH) assessment before use.
