The device has a combustion grate formed as part of a base of a primary combustion chamber, where an ash tray is arranged under the combustion chamber. The combustion grate comprises two combustion grate plates (3b) that are arranged one above the other and comprise multiple ash apertures (5). The apertures are displaceable relative to each other in the base of the combustion chamber. The apertures are aligned one above the other in a cleaning position and moved relative to each other in an operational position such that the apertures are partially or not at all aligned relative to each other. |
