    Apparatus for burning solid fuels, in particular wood pellets, wood chips and the like, with a load-bearing housing, which can be flanged to an oven, heat exchanger, boiler or the like, in which a preferably cylindrical combustion tube is rotatably mounted on rollers or gears as the main part of a combustion chamber, of which The drive is positively via a toothing or the like from a drive unit on at least one of the bearing rollers and from the bearing rollers on the Brennrohr.Die axial guidance of the combustion tube is effected by an engaging in an inner peripheral groove of the combustion tube Plate, which is connected to the fuel supply device or the burner housing, and to which the ignition unit is also attached. The supporting housing is preferably made airtight and passes the combustion air to the air inlet provided with the combustion tube and the ignition unit periodic further rotation of the combustion tube during combustion creates a self-cleaning effect of the combustion chamber.

    Burner for solid fuels with rotatable combustion tube
    The invention relates to a burner for solid fuels, in particular for wood pellets or other biogenic fuels, such as pellets of vegetable waste or wood chips, with a preferably horizontal axis rotatable combustion chamber, which consists of a provided with radial air intakes rotatable combustion tube and an inner circumferential Groove engaging rear end plate is formed.
    The combustion tube is mounted on rollers, of which at least one is provided with a toothing and engages in a toothing attached to the combustion tube.
    This roller is driven by a drive unit mounted on the burner housing, see FIG. 1 and FIG. 2.
    The rear end plate of the combustion chamber guides the combustion tube in the axial direction, is attached to the fuel supply pipe in an embodiment shown in Fig. 1 and connected to the ignition device.
    In the case of combustion of biogenic fuels, the problem is that the openings for the supply of combustion air are closed by ash and slag and tarry combustion residues after some time, resulting in poor combustion and great cleaning and maintenance.
    Mechanical cleaning devices are prone to failure.
    By periodic further rotation of the combustion tube during combustion, the ash is carried out supported by the air flow and burned away combustion residues back, whereby a consistent good combustion is guaranteed without cleaning and maintenance.
    Previous drive systems, such as e.g. in DE 69703210 T2 or EP 0 346531 Al or AT 006506 Ul mentioned, have the disadvantage that the drive elements are connected directly to the hot combustion tube, resulting in heat transfer problems and short life.
    The drive of the drum on one of the bearing rollers has the advantage that the preferably mounted below roller is located in the coolest region of the burner and no direct heat transfer from the combustion tube to the drive pinion and on to the engine.
    Another advantage is that the burner housing can be made narrow and compact. 2/8 ♦ ·· ♦ ♦ ··········································· ♦
    In the drawings Fig. 1 and Fig. 2 embodiments of the invention are shown.
    Fig.l shows a longitudinal section through a burner with a horizontal fuel feeder with screw,
    Fig. 2 shows a section across a burner with a
    Fuel supply device through a down from the top into the combustion chamber chute, wherein the combustion tube 1 rests on the front open side 5 on two rollers 14 in the air guide housing 8 and on the rear side carries a ring gear 11 which is mounted between at least three rollers 12, of which at least One has a toothing and engages in the ring gear 11.
    The drive of the combustion tube is carried by a mounted on the supporting housing 6 drive unit 13 with a gear, which engages in the toothed bearing roller.
    The axial guidance of the combustion tube takes place via the rear end plate 7, which engages in the inner peripheral groove of the combustion tube and closes the combustion chamber to the rear.
    This plate 7 is either attached to the burner feed tube as shown in Fig. 1 or attached to the supporting housing 6 as shown in Fig. 2 and connected to the ignition device 4. The hot ignition air flows through a recess in this plate on the fuel.
    On the supporting housing, the fan 3 is mounted, the combustion air flows past the drive and bearing rollers in the combustion tube housing 8 and through the radial air inlets into the combustion tube. 1
    The combustion tube housing is sealed to the front of the combustion tube 5 and formed so that the combustion air flows mainly from below into the combustion tube and thus the falling through of ashes is largely prevented.
    The combustion tube housing 8 has a cleaning opening 10 at the bottom.
    Part of the combustion air is passed through the ignition unit and the
    Guided fuel supply unit and prevents burn-back at a standstill combustion tube.
    By further rotation of the combustion tube after a time adjustable by the combustion amount of fuel to a certain angle of rotation, the fuel is conveyed on and fresh fuel can be nachgefördert or in the embodiment of FIG. 2 in the chute slipping to prevent backwater. 3/8 •···················································
    By the periodic further rotation thus a greater power can be achieved and at the same time there is a self-cleaning of the burner, since not only the ash is conveyed out, but also burning combustion residues and deposits are burned. 4.8
