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.
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

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.
The drag-chain conveyor used in the collecting phase for the wet-ashing is located under the boiler. The ash flows into the water and is then transported to the ash container.
