Boiler Water Treatment
Oxygen scavengers, alkalinity builders, scale inhibitors, and condensate return treatment chemicals for steam boilers in Kenyan factories.
Quick Answer — Boiler Water Treatment
Boiler water treatment chemicals supplied by Kiki's in Kenya include Sodium Hydroxide (Caustic Soda) and Soda Ash for pH/alkalinity elevation (pH 9.5-10.5), and Hydrochloric Acid 33% for offline tube scale descaling.
Boiler water treatment is the specialized chemical conditioning of steam generator feedwater to prevent scaling, dissolved oxygen corrosion, and steam carryover.
Key Facts
- •Maintaining boiler water pH between 9.5 and 10.5 protects steel from acidic corrosion.
- •1mm of calcium scale reduces heat transfer efficiency and increases fuel consumption by 10%.
- •Caustic Soda converts hard water minerals into non-adherent, blowdown-removable sludge.
Primary Use Cases
Technical Process
Boiler feedwater chemistry prevents three major operational failures: scale deposition, dissolved oxygen corrosion, and boiler water carryover.
Alkalinity is maintained using Caustic Soda lye or Soda Ash Light to precipitate residual hard water calcium as dense, blowdown-removable sludge rather than hard crystalline scale.
Dissolved oxygen pitting is controlled through chemical scavenging, while occasional offline acid descaling with Hydrochloric Acid 33% (inhibited) or Sulfuric Acid restores heat transfer efficiency in heavily scaled firetube boilers.
Standard Application Process
- 1
Softener Pretreatment & Hardness Check
Pass raw water through ion-exchange softeners and verify hardness (<2 ppm CaCO3).
- 2
Alkalinity & pH Adjustment
Meter Caustic Soda or Soda Ash to maintain boiler water pH between 9.5 and 10.5.
- 3
Oxygen Scavenging & Sludge Conditioning
Inject oxygen scavengers into the deaerator storage section to prevent thermal pitting.
- 4
Blowdown Control & Dissolved Solids Check
Perform routine bottom blowdown to control Total Dissolved Solids (TDS) below 3,000 ppm.

Key Performance Advantages
- ✓Prevents Tube Rupture & Explosion
Eliminates insulating scale deposits that cause localized boiler tube overheating and rupture.
- ✓Fuel Consumption Optimization
1mm of scale causes a 10% increase in boiler fuel usage; chemical treatment maintains peak heat transfer efficiency.
- ✓Extended Boiler Equipment Lifespan
Maintains passive protective magnetite (Fe3O4) steel film, doubling boiler operational service life.
