Applications

  • Anaerobic digesters

     

    Biogas production in anaerobic digesters. Compressor and blower for gas collection from digester

     

    • Screw compressors, Single stage blowers
  • Direct Heat and Power CHP

     

    Direct Heat and Power CHP : Electricity-Fuel gas.  In site power plant equipments compress the feed gas for the turbines to the appropriate pressure.

     

    • Oil injected screw compressors, Oil-free screw compressors
  • Landfill gas movement : Gas gathering

     

    Gas contains methane and carbon dioxide. Landfill gas is collected and sent to the gas treatment unit.

     

    • Lobe Blowers
  • Gas treatment plant

     

    If biomethane is being fed to grid there may be a requirement for a biomethane compressor

     

    • Screw compressors, Piston
  • CNGV Compressed Natural Gas Vehicle

     

    BioMethane Compressed gas – vehicle fuel & distribution.

     

    • Piston
  • Biogas treatment PSA

     

    The biogas is first compressed, then cooled and desulphurized. A large plant may have 2 stages of biogas compression (up to 3 units – up to 11 bar).

     

    • Screw compressors
  • HPWS High Pressure Water Scrubbing

     

    Typically there will be 2 biogas compressors feeding the absorption column. If biomethane is being fed to grid there may be a requirement for a biomethane compressor

     

  • Biogas treatment

     

    Membrane separation 1 or 2 compressor according to capacity

     

  • Heaters for biomass / wood / waste boiler

     

     
    • Heaters
  • Storage

     

    Storage compressors,  High pressure diaphragm compressors and Hybrids.

     

    • Hybrids
  • Feed gas for the turbines

     

    In site power plant equipments compress the feed gas for the turbines to the appropriate pressure.

     

    • Oil injected screw compressors, Oil-free screw compressors
  • Ethanol process

     

    Ethanol process and fuel fans

     

    • Cooling fans, Centrifugal fans
  • Anaerobic digesters

     

    Exhaust air

     

    • Fans
  • Wave energy

     

    Shorebased wave systems (Wells turbines)

     

    • Centrifugal Fans
  • Forced draught fans

     

    Forced draught fans move ambient air at low pressure through the air preheater to provide heated oxygen for the combustion process.

     

    • Fans
  • Induced draught fans

     

    Induced draught fans are vital in maintaining furnace pressure at just below atmospheric pressure. They draw the flue gases out of the boiler into the air preheater.

     

    • Fans
  • Primary air fans

     

    Primary air fans are used to move air through the air preheater in coal and biomass fuelled stations. The size and configuration of the fan depends on the temperature of the primary air.

     

    • Fans
  • Secondary air fans

     

    Secondary air fans feed into the boiler combustion chamber at a higher point than the primary air to promote more complete combustion.
