Metering pumps are an essential aid to water treatment processes in thermal power plants, with their capacity for achieving highly-accurate dosage and flow rates making them ideal for injecting water-treatment chemicals into make-up water under pressure.
Key water-treatment processes in power generation include:
- Phosphate dosing to prevent scale formation in boiler tubes and maintain pH value to stop corrosion
- Dosing of compounds such as ferric chloride and sulphuric acid for water purification
- Metering caustic soda and detergent for CO2 scrubbing
- Denitrification via urea and ammonia injection
