A solid fuel combustion burner comprises a cartridge (7) that may be inserted into a central heater, which cartridge delimits a combustion chamber (8). Air supply orifices in a bottom (11) of the cartridge have the shape of elongated slots (28) which are oblique in a direction inwardly/frontwardly and which each one extends on one hand a bit along the bottom and on the other hand a bit upwards along an adjacent side wall (12). The slots (28) are located in a restricted region adjacent to an opening (27) for feeding in fuel and have the purpose of supplying primary air as well as secondary air to a glow hearth located on the bottom (11). |
