Trisodium Phosphate Functions in Power Plants
1. Scale Prevention and Water Quality Regulation
- Inhibit scale formation: Trisodium phosphate combines with calcium and magnesium in water to generate insoluble calcium phosphate and magnesium phosphate precipitation, reducing water hardness and preventing scale formation on boiler walls under high temperature and pressure.
- Adjust pH: Maintains boiler water pH in the range of 9-12, inhibiting acidic corrosion reactions and reducing metal erosion by oxygen and carbon dioxide.
2. Corrosion Protection
- Form a protective film: Reacts with boiler metal surfaces to form a dense phosphate protective film, blocking corrosive substances.
- Control dissolved oxygen effects: Reduces dissolved oxygen concentration through alkaline environment adjustment.
3. Improve Operation Efficiency and Equipment Life
- Optimized heat transfer: Maintains clean boiler heating surfaces, preventing thermal efficiency reduction (scale can reduce efficiency by >10%).
- Extend equipment life: Reduces corrosion and scale damage, extending boiler life by over 30%.
4. Operation and Maintenance Points
- Dosing control: Typically added as 10% aqueous solution (30-60g per ton of water), adjusted based on water hardness and boiler load.
- Water quality monitoring: Regular testing of pH, phosphoric acid concentration, and calcium/magnesium ion content (maintain PO₄³⁻ at 5-15 mg/L).
- Sewage management: Regular blowdown to discharge loose sediment and prevent secondary scaling.
5. Synergies with Other Agents
Trisodium phosphate is often used with:
- Sodium hydroxide: Helps adjust pH to ideal range (9-12)
- Deaerator: Further reduces dissolved oxygen concentration, enhancing anti-corrosion effect
