Flue Gas Desulphurisation

Friday, 13 June 2008

Large vertical axis batch centrifuges are used for de-watering the gypsum slurries that result from the removal of SO2 from flue gases in fossil-fuel-burning power utilities. They produce low chloride, low moisture commercial grade gypsum. Solid bowl decanter centrifuges are also available for this application where the gypsum is used for land-fill or dyke building.

The Broadbent range of FGD centrifuges have capacities from 120L to 1400L and are able to produce up to produce 12.5 T/hr dry gypsum. Installations of these machines display the following advantages:

  • Well suited to the production of low chloride, low moisture commercial grade gypsum
  • Superior results compared with vacuum belt filters 
  • Able to process a wide range of gypsum particle sizes 
  • High processing rates 
  • Finished product de-watered to 8% or less (dry weight) 
  • Installation controls interface with main plant controls 
  • Regenerative variable frequency inverter fed drives 
  • Low energy consumption 
  • Advanced chemical resistant materials of construction
