Boiler process additive SYWATER ® Technical data for BWT 9801

Usage:

SYWATER ® BWT 9801 is a scale and corrosion inhibitor used in the water and steam system of subcritical boilers, to protect the boiler body and related pipeline equipment that uses desalinated water as makeup water. Forming a molecular film that adsorbs onto the metal surface of the equipment's inner wall to prevent corrosion of the liquid and gas relative to the metal. It helps to reduce and prevent the formation of scale and adhesion deposition. It can effectively control the pH value of boiler water and steam, reduce the agglomeration caused by the addition of other chemicals in boiler water, and is more suitable for film formation protection and corrosion control under subcritical conditions, ensuring stable hydrogen conductivity of steam and stable operation of the boiler, achieving water conservation and emission reduction, and reducing carbon dioxide emissions. It has very high economic and social benefits.

Advantages:

Single product, liquid form, simple dosing system;

Can prevent metal corrosion, especially in the condensation and evaporation section;

Form a protective film to protect the boiler, steam pipeline, and condensate pipeline;

Adjust the pH value of the entire system, including the condensing system;

By avoiding surface fouling and changing the condensation heat transfer state, heat transfer efficiency can be improved.

Measurement standards:

SYWATER ® BWT 9801 can be injected directly into the boiler drum through a dosing pump.

Dosage of steam system:

When using this medication, we recommend controlling the pH above 8.8, based on 20% evaporation, and adding an initial dosage of 8ppm. After the system is stable, the dosage can be adjusted appropriately according to the on-site situation. The specific control parameters are subject to national standards.

Important precautions:

SYWATER ® When used in combination with ordinary boiler water additives (such as phosphate, even at very small dosages), BWT 9801 may weaken the actual efficacy of the product and disrupt the optimal controlled dosage of this agent.

Residual analysis:

The remaining drug concentration can be measured by a simple colorimetric method or spectrophotometer.
