Power Generation
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
Chemical metering pumps used in power plants must meet the dual demands of precision and durability in order to help operators maintain efficient running and prevent costly unplanned downtime.
