Abstract

A solid fuel combustion burner comprises a cartridge (7) that may be inserted into a central heater, which cart-ridge 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/front-wardly 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).

Claims (9)

1. A burner for the burning of solid fuels, such as pellets, comprising a cartridge (7) that may be inserted into a central heater (1), said cartridge (7) delimiting a combustion chamber (8) that is open relative to the interior of the heater and having a bottom (11), below which there is at least one cavity (33) that is open outwardly, from the central heater, but closed inwardly, to which cavity air may be supplied from out-side, the bottom along opposing longitudinal sides transposing into protruding side walls (12), in which there are orifices for the supply of air from the cavity (33) into the combustion chamber (8), so as to create of a combustible gas mixture together with gasified constituents from a glow hearth located on said bottom (11), to which hearth fuel is supplied from above via a fuel feed canal (25), characterised in that said air supply orifices have the shape of elongated slots (28), which are oblique in a direction inwards/front-wards when seen in the feed direction of the fuel bodies, and which each one extends on one hand a bit along the bottom (11), and on the other hand a bit upwardly, along the indivi-dual side wall (12), said slots being located in a restricted region adjacent to an opening (27) to the fuel feed canal (25) and having the purpose of supplying primary air from below, as well as secondary air from the side, to said glow hearth.
2. Burner according to claim 1, characterized in that the cartridge (7) is connected with an external housing (17), into which opens the open outer end of the cavity (33) and in which extends a tube (25) serving as a fuel feed canal, more specifically to a fuel intake feed opening (27) recessed in a front wall (19), which opening (27) is placed at a level above the bottom (11) of the cartridge.
3. Burner according to claim 1 or 2, characteri-zed in that the cartridge (7) is composed of a lower part (10) and an upper part (9) that is detachably connected with the former, said upper part being in the form of a cap.
4. Burner according to claim 3, characterized in that the lower part consists of a box construction (10), in which said cavity (33) is accomodated.
5. Burner according to claim 4, characterized in that the bottom of the combustion chamber (8) consists of a planar horizontal plate (11) and that said side walls (12) are planar and oblique in a direction upwardly/outwardly relative to the bottom plate.
6. Burner according to any of claims 2 to 5, charac-terized in that, in connection with the front wall (19) of the housing (17) are on either side of the fuel intake feed opening (27) provided tube pieces (31) for the supply of secondary air in the form of two separate jets located above the lower part (10) of the cartridge.
7. Burner according to any of claims 3 to 6, charac-terized in that the cap (9) of the cartridge (7) is cross-sectionally arched.
8. Burner according to any of the preceding claims, cha-racterized in that in a region near the inner end of the cartridge (7) is in each individual side wall (12) reces-sed at least one hole (30) in order to supply tertiary air from said cavity (33) to the gas mixture in the combustion chamber (8).
9. Burner according to any of claims 2 to 8, charac-terized in that on the outside of the housing (17) is provided a fan (24) for blowing in air into the interior of the housing.
