Corrosion Control Chemicals for Condensate Water Treatment
Silica Dispersant for Boiler Feed Water.
pH Booster Cum Alkalinity Builder.
Pre Cleaning and Passiviting Chemical new Boiler
Problems Generate in the Boiler Due to Boiler Feed Water
Scale formation
Corrosion
Priming, foaming and carry over
Caustik embrittlement
SCALE FORMATION
Ca(HCO3)2 + Heat ⇒ H2O + CO2 + CaCO3 (Scale)
Factors For Scale Formation in Boiler
Water contains lots of dissolved solids, Calcium and magnesium are the major hardness components and primary source of scale in boiler and feed system heat exchanger equipment.
Silica creates hard scale in boilers.
PO4 also Creates hard scale in boilers

CORROSION
In below reaction a temperature rise provides enough additional energy to accelerate reactions at the metal surfaces, resulting in a rapid and severe corrosion:
Fe + 1/2 O2 + H2O ⇒ Fe(OH)2
Corrosion is the principal effect of dissolved carbon dioxide
The gas will dissolve in water, producing corrosive carbonic acid:
H2O + CO2 ⇒ H2CO3 (Carbonic Acid)
Carbonic acid is acidic in nature so it will react with metal and make it corrosive.
Factors For Corrosion in Boiler
Dissolved oxygen cause hematite (red rust).
Acidic attack.
Major Benefits of Boiler Water Treatment
Save energy losses and stabilizes fuel consumption
Increase life of your boiler
Ensures optimum heat transfer
Reduces unnecessary shutdown/maintenance
Saves frequent acid cleaning cost
