Condensate Water  

Condensate water filtration is a key point in power plant system. A stable and reliable condensate water unit can protect boiler and steam turbine safety running, extend resin regeneration circle and reduce system starting time.

 

When unit running, boiler main pollutions are silicone and iron. Iron will be corrosion and effect boiler and steam turbine safety running.

 

The pore size of iron is 3~15um. When temperature change, iron will melt in condensate water, so it is best chance to removal them.

 

 

  • ① Removal Iron before Mixed Media Bed ( ultra supercritical thermal power generating units )
  • Function: Remove iron and copper corrosion particles and extend de-salt system operating cycle and protect resign. 10um depth filters are commonly used when system starting, 5um/1um absolute filter cartridges are used when system is running regularly.

    • ■ 64-H2D Filter Cartridge
    • ■ HF150 Filter Cartridge

     

  • ② Powdered Resin Precoat Filter System (steam turbine unit)
  • Function: Widely used in steam turbine unit. Cover mixture which made of powdered ion exchange resin and fiber powder on PP wound filter cartridge.
    Remove iron, Colloid silicones, suspended solids and metallic oxides and have some effect on ion exchange.
    Corrosion items are separated by powdered resin from PP wound filter.
    You can flush corrosion items with powdered resin by explosion the filter. PP wound filter to be support body of powdered resin prevent the powder into heat system. 4~5um is commonly used.

  • ③ Boiler Feed Water Pre-RO Filtration
  • Fuction: Stop new particles which are produced in the process or not removed in prefiltration to go into RO system, and protect high pressure pump and RO system.
    A good Pre-RO filtration system can increase inlet water quality remarkably before go into RO system.
    RO membrane life time can be extended,chemical regeneration can be reduced, therefore system cost is reduced too. 5um/10um is commonly used.
