  • the fuel pellet stove described therein comprises a storage chamber for the fuel granules in a combustion chamber. Furthermore, the combustion chamber defines a flame chamber. Initially, individual pellets flow from the storage chamber due to gravity to a fire grate. There, the pellets can be ignited by means of a Anbrandtosffens. In the course of combustion, pellets flow from the storage chamber to the grate as pellets are burned and fire residues escape into a collecting container through openings provided in the bottom of the grate. As a result of burning off of the pellets, heat develops in the combustion chamber. This heat heats the stored pellets in the storage chamber.

  • the flame pattern of conventional heating appliances emits similar flames.
  • the heat released during combustion of the pyrolysis gases maintains the process of pyrolysis in the storage chamber.
  • the granular precursor obtained in the first thermal recovery phase by the pyrolysis is then burned with low residue in the second thermal recovery phase.
