The filter material is burned completely or partially in a low ash phase of a burning-off process of fuel within the heating device, where the filter material is automatically supplied into the burning chamber of the heating device. The flue gas active through the filter material is sucked and/or blown in a burning phase. The filter material is supplied into the burning chamber during the burning phase. An independent claim is also included for a heating device comprising a filter device.</p> |
