Dosing metering pumps are critical auxiliary equipment in power plants and energy stations, responsible for accurate, stable, and continuous injection of chemicals to ensure safe operation, equipment protection, water quality control, and environmental compliance.
1. Boiler Water Treatment
- Inject ammonia, hydrazine, phosphate, and oxygen scavengers
- Control pH value, prevent scaling, reduce corrosion of boiler pipes and heat exchangers
- Ensure long-term stable operation of high-pressure boilers
2. Cooling Water Treatment
- Add biocides, scale inhibitors, corrosion inhibitors, and bactericides
- Prevent algae, biofouling, and sediment in cooling towers and circulating water systems
- Reduce equipment blockage and improve heat exchange efficiency
3. Flue Gas Desulfurization (FGD)
- Meter and transfer limestone slurry, lime milk, and absorbents
- Remove SO₂ from flue gas to meet emission standards
- Essential for coal-fired power plants and thermal power stations
4. Wastewater & Effluent Treatment
- Add acids, alkalis, flocculants, and coagulants
- Adjust pH, precipitate pollutants, purify wastewater
- Meet local environmental discharge requirements
5. Chemical Cleaning & Maintenance
- Inject cleaning agents, pickling solutions, and passivators
- Remove scale and rust from boilers, pipelines, and heat exchangers
- Extend service life of power generation equipment
6. Key Advantages in Power Industry Applications
- High precision and stable flow rate
- Corrosion-resistant structure for harsh chemical media
- Leak-proof design for safe operation
- Suitable for 24-hour continuous duty
- Easy to install, maintain, and integrate with automatic control systems
