Ash removal

The Palokärki systems always include automatic ash removal, which takes care of transferring the ash to the receptacle reserved for this purpose outside the building.

Dry-ash removal

Ash removal is performed as dry-ashing by using a screw conveyor which collects the ash:

  • From under the grate
  • From the fire chamber
  • From the convection
  • From the cyclone

Wet-ash removal

When the fuel used is, for example, crushed construction waste which includes nails, a so-called wet-ashing will be used. The ash is suspended in water and transferred to the ash receptacle by using drag-chain conveyors.
