→ 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
Scale Nomenclature
→ Anhydrite
→ Brucite
→ Mark Copper
→ Hematite
→ Magnetite
→ Quartz
→ Thenardite
→ Wollastonic
Cost Increasing by SCALING
| Thickness of scale | Increases in fuel consumption due to this scale |
|---|---|
| 1/2 mm | 2% |
| 1 mm | 4% |
| 2 mm | 6% |
| 4 mm | 10% |
| 8 mm | 20% |
| 16 mm | 40% |
| 30 mm | 80% |
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
→ Mark Increase life of your boiler
→ Ensures optimum heat transfer
→ Reduces unnecessary shutdown/maintenance
→ Saves frequent acid cleaning cost
