Corrosion Scale Inhibitor Boiler Treatment

Dosage

• Dosage (ppm) = (Feedwater Hardness × F) + (Feedwater Iron × 20)
• Select Factor F based on boiler pressure:
• Use F = 23 for boilers up to 30 bar.

Most industrial and utility boilers globally operate between 10–40 bar (low to medium pressure steam production).

F = 23 works well for boilers using softened feedwater, which is very common internationally.

Even for pressures slightly above 35 bar (up to 45 bar), using F = 24 still keeps treatment safe and effective without under- or overdosing.

Maximum pressure limit for this product is 60 bar.

RXSOL Boiler Corrosion Scale Treatment should be fed continuously in order to properly protect the boiler. Boiler Corrosion Scale Treatment can be fed neat or in any convenient dilution made up in soft water or cooled condensate. Boiler Corrosion Scale Treatment should be dosed using individual chemical dosing unit, must not be mixed with oxygen scavengers or condensate system corrosion inhibitors in concentrated form (e.g. concentrated chemical products should not be mixed together).

Sampling and Testing
Boiler Corrosion Scale Treatment is normally used in conjunction with RXSOL Alkalinity Control treatment in a conventional alkaline phosphate treatment programme for HP boilers, where independent control of phosphate and alkalinity control is required.

Dosing and Control
The dosage of Boiler Corrosion Scale Treatment depends on a number of operational factors such as feed-water quality, boiler design and steam rate. Control of Boiler Corrosion Scale Treatment is by a simple test to give the required level of phosphate (as PO4) in the boiler water. A simple Hardness Treatment test kit is available for this purpose. NOTE: Dependent on water quality, Boiler Corrosion Scale Treatment dosed at 0.25 liters/ton will increase the phosphate reserve by the order of 10mg/l.

How Corrosion Scale Inhibitor Boiler Treatment Improves Efficiency:

Prevents Scale Formation

• Inhibits deposition of calcium, magnesium, and other hardness salts
• Keeps heat transfer surfaces clean, ensuring optimal thermal conductivity

Reduces Fuel Consumption

• Clean surfaces transfer heat more efficiently
• Less fuel is required to generate the same amount of steam

Minimizes Corrosion

• Protects metal surfaces from oxidation and chemical attack
• Reduces the risk of leaks, pitting, and structural damage

Extends Boiler Life

• Less corrosion and scale mean fewer breakdowns
• Prolongs the service life of tubes, pumps, and other components

Lowers Maintenance Costs

• Reduces the need for cleaning, repairs, and part replacements
• Minimizes downtime and operational disruptions

Improves Water Cycle Efficiency

• Promotes cleaner condensate return
• Enhances overall system stability and performance
