Definitions
- 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 about a substantially horizontal axis rotatable combustion chamber, which consists of a provided with radial air intakes rotatable combustion tube and an inner circumferential groove eiimide fixed end plate is formed.
- the present invention can meet these requirements better than the previously known embodiments (from WO 2008 141594 A2 . GB 2198519A . US 6164220 and others), paying attention to a simple and inexpensive construction without complicated sealing systems and to a reliable and service-friendly design.
- the invention relates to a burner for solid fuels, with a about a substantially horizontal axis rotatable combustion chamber, which is formed from a provided with radial air inlets rotatable combustion tube and in an inner circumferential groove eiimide fixed end plate.
- the combustion tube is mounted on rollers and provided with a race and a sprocket.
- the rollers are arranged so that they are in the air flow of the combustion air and are cooled by this.
- a toothed gear which is preferably mounted under the combustion tube in the housing engages on the one hand in the toothing of the ring gear on the combustion tube and is driven on the other side by a gear wheel mounted on the shaft of a geared motor, see FIGS. 1 and 2 ,
- the rear end plate of the combustion chamber is not connected to the combustion tube, but engages in a circumferential groove on the inside of the combustion tube and guides the combustion tube in the axial direction.
- the end plate is connected to the outer tube of the fuel feeder screw and preferably has in the lower area air flow openings.
- the fuel supply pipe is also traversed and cooled by a mounted at the top inside the housing bore with air.
- the ignition unit can be mounted at the optimum location directly under the fuel supply pipe at the end plate to ensure rapid ignition of the introduced fuel without much smoke.
- the fuel supply unit consists of the feeder screw and an upstream rotary valve, which are driven together ( Fig.1 ), or an upstream ball valve with self-closing spring drive ( Fig.2 ), which ensures that the combustion air is supplied only by the blower and can not be sucked through the fuel through, so no burn-back in case of failure of the blower can occur.
- the drive of the combustion tube is independent of the drive of the fuel supply system, thereby not only during combustion periodically changeable over a control times, the burner tube can be further rotated briefly to maintain the self-cleaning effect, it can be carried out before the ignition a Entaschungszyklus, where by longer Turning the combustion tube, the ash is carried out.
- the rotation cycles can be controlled so that the combustion material located in the combustion tube is completely burned and no gassing left behind, which reduces the risk of burnback, increases the reliability and significantly reduces maintenance.
- the arrangement of all components on and in a supporting closed housing not only creates a compact burner unit, which can be flanged to any oven, heat exchanger or boiler, it is caused by the flanged fan overpressure in the housing, which without additional air ducts or air ducting the combustion air leads to the individual air inlet openings of the combustion tube and at the same time cools all components, so that the burner is not hot outside even at full power.
- the combustion air blower is preferably connected to a controller, where the air power can be changed, but the air flow can also be changed by the size and arrangement of the individual air inlet openings.
- 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.
- This plate 7 is either on the burner feed tube as in Fig. 1 represented or on the supporting housing 6 as in Fig. 2 drawn attached and connected to the ignition device 4.
- the fan 3 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 (air guide 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 fall-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 fuel supply unit and prevents burn-back when the burner tube is stationary.
- cleaning and ash removal cycles can be programmed.

Abstract
Description
Die Erfindung betrifft einen Brenner für feste Brennstoffe, insbesondere für Holzpellets oder andere biogene Brennstoffe, etwa Pellets aus pflanzlichen Abfällen oder Hackgut, mit einer um eine im wesentlichen horizontale Achse drehbaren Brennkammer, welche aus einem mit radialen Lufteinlässen versehenen drehbaren Brennrohr und einer in eine innenliegende umlaufende Nut eigreifende feststehende Abschlussplatte gebildet wird.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 about a substantially horizontal axis rotatable combustion chamber, which consists of a provided with radial air intakes rotatable combustion tube and an inner circumferential groove eigreifende fixed end plate is formed.
Aus dem Stand der Technik ist bekannt, dass mit Brennern mit drehbarer Brennkammer eine kontinuierliche und vollständige Verbrennung bei hohem Wirkungsgrad erreichbar ist und diese deshalb auch für Brennstoffe aus minderwertigeren Rohstoffen, wie etwa Pellets aus rasch nachwachsenden pflanzlichen Rohstoffen, gut geeignet sind. Bei der Verbrennung solcher Brennstoffe ist jedoch eine betriebssichere und langlebige Ausführung der Lagerung der drehbaren Brennkammer und die Anordnung der Antriebselemente besonders wichtig, um Störungen durch zu hohe Temperaturen bei Lager- und Antriebsteilen zu vermeiden. Wichtig ist auch die Art der Führung der Verbrennungsluft, da diese die kritischen Bauteile umströmen und kühlen soll.It is known from the prior art that with rotary combustor burners, continuous and complete combustion can be achieved with high efficiency and therefore are well suited to fuels of lower quality raw materials, such as pellets of rapidly renewable vegetable raw materials. In the combustion of such fuels, however, a reliable and durable design of the bearing of the rotary combustion chamber and the arrangement of the drive elements is particularly important to avoid disturbances caused by excessive temperatures in storage and drive parts. Also important is the way in which the combustion air is guided, since it is intended to flow around and cool the critical components.
Die vorliegende Erfindung kann diese Anforderungen besser als die bisher bekannten Ausführungen (aus
Bisherige Antriebsysteme, wie z.B. in
Gegenüber
dass das Brennrohr nicht direkt axial und von einer Kette angetrieben wird, sondern über ein gelagertes Zwischenzahnrad, welches im kühlen Bereich unter dem Brennrohr angeordnet ist, und wo der Antriebsmotor unterhalb angeordnet ist,
dass die hintere Abschlussplatte der Brennkammer nicht mit dem Brennrohr verbunden ist, sondern in eine umlaufende Nut des Brennrohres eingreift und dieses axial führt,
dass die hintere Abschlussplatte am Rohr der Zubringerschnecke befestigt ist und die Zündvorrichtung dahinter fix angeordnet ist. Bei
dass das Gebläse an einem tragenden dichten Gehäuse angeflanscht ist und so keine weiteren Luftführungsschläuche oder Luftführungseinrichtungen erforderlich sind.Across from
that the combustion tube is not directly driven axially and by a chain, but via a mounted idler gear, which is arranged in the cool region below the combustion tube, and where the drive motor is arranged below,
that the rear end plate of the combustion chamber is not connected to the combustion tube, but engages in a circumferential groove of the combustion tube and this leads axially,
that the rear end plate is attached to the pipe of the feeder screw and the ignition device is fixed behind it. at
that the blower is flanged to a supporting tight housing and so no further air duct hoses or air ducting devices are required.
Die Erfindung betrifft einen Brenner für feste Brennstoffe, mit einer um eine im wesentlichen horizontale Achse drehbaren Brennkammer, welche aus einem mit radialen Lufteinlässen versehenen drehbaren Brennrohr und einer in eine innenliegende umlaufende Nut eigreifende feststehende Abschlussplatte gebildet wird.The invention relates to a burner for solid fuels, with a about a substantially horizontal axis rotatable combustion chamber, which is formed from a provided with radial air inlets rotatable combustion tube and in an inner circumferential groove eigreifende fixed end plate.
Das Brennrohr ist auf Rollen gelagert und mit einem Laufring und einem Zahnkranz versehen. Die Rollen sind so angeordnet, dass sie im Luftstrom der Verbrennungsluft liegen und von diesem gekühlt werden.The combustion tube is mounted on rollers and provided with a race and a sprocket. The rollers are arranged so that they are in the air flow of the combustion air and are cooled by this.
Ein vorzugsweise unter dem Brennrohr im Gehäuse gelagertes Zahnrad greift einerseits in die Verzahnung des Zahnkranzes am Brennrohr ein und wird auf der anderen Seite von einem an der Welle eines Getriebemotors gelagertes Zahnrad angetrieben, siehe
Durch diese Anordnung erfolgt keine direkte Wärmeübertragung vom Brennrohr auf den Antriebsmotor und der Motor kann im kühlsten Bereich der Brennerumgebung platziert werden, trotzdem ist der Antrieb wartungsfrei und keine Nachstell- oder Nachspannvorrichtung erforderlich, wie das bei einem Kettentrieb erforderlich wäre.By this arrangement, there is no direct heat transfer from the combustion tube to the drive motor and the motor can be placed in the coolest region of the burner environment, yet the drive is maintenance-free and no readjustment or retightening device is required, as would be required in a chain drive.
Die hintere Abschlussplatte der Brennkammer ist mit dem Brennrohr nicht verbunden, sondern greift in eine umlaufende Nut auf der Innenseite des Brennrohres ein und führt das Brennrohr in axialer Richtung. Die Abschlussplatte ist mit dem Außenrohr der Brennstoff-Zubringerschnecke verbunden und hat vorzugsweise im unteren Bereich Luftdurchströmungsöffnungen.The rear end plate of the combustion chamber is not connected to the combustion tube, but engages in a circumferential groove on the inside of the combustion tube and guides the combustion tube in the axial direction. The end plate is connected to the outer tube of the fuel feeder screw and preferably has in the lower area air flow openings.
Durch diese Anordnung erfolgt keine direkte Wärmeübertragung vom Brennrohr auf die Abschlussplatte. Durch die Luftöffnungen wird die Platte von der durchströmenden Verbrennungsluft gekühlt und dadurch wenig Wärme auf das Brennstoffzuführungsrohr übertragen, was die Gefahr eines Rückbrandes im Rohr verringert.By this arrangement, there is no direct heat transfer from the combustion tube to the end plate. Through the air openings, the plate is cooled by the flowing combustion air and thereby transferred little heat to the fuel supply pipe, which reduces the risk of burn-back in the pipe.
Das Brennstoffzuführungsrohr wird durch eine an der Oberseite innerhalb des Gehäuses angebrachte Bohrung ebenfalls mit Luft durchströmt und gekühlt.The fuel supply pipe is also traversed and cooled by a mounted at the top inside the housing bore with air.
Die Zündeinheit kann bei dieser Anordnung direkt unter dem Brennstoffzuführungsrohr an der Abschlussplatte an optimaler Stelle angebracht werden, um eine rasche Entzündung des eingebrachten Brennstoffes ohne viel Rauchentwicklung zu gewährleisten.In this arrangement, the ignition unit can be mounted at the optimum location directly under the fuel supply pipe at the end plate to ensure rapid ignition of the introduced fuel without much smoke.
Die Brennstoffzuführungseinheit besteht aus der Zubringerschnecke und einer vorgeschalteten Zellradschleuse, welche gemeinsam angetrieben werden (
Bei der Verbrennung von biogenen Brennstoffen ist das Problem, dass die Öffnungen für die Zufuhr von Verbrennungsluft nach einiger Zeit durch Asche und Schlacke und teerartige Verbrennungsrückstände verschlossen werden, was zu einer schlechten Verbrennung und großem Reinigungs- und Wartungsaufwand führt.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.
Mechanische Reinigungseinrichtungen sind aufwendig und störungsanfällig.Mechanical cleaning devices are expensive and prone to failure.
Durch periodische Weiterdrehung des Brennrohres während der Verbrennung wird die Asche unterstützt vom Luftstrom hinausbefördert und anhaftende Verbrennungsrückstände wieder weggebrannt, wodurch eine gleichbleibende gute Verbrennung ohne Reinigungs- und Wartungsaufwand gewährleistet ist.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.
Der Antrieb des Brennrohres erfolgt unabhängig vom Antrieb des Brennstoffzuführungssystems, dadurch kann nicht nur während der Verbrennung periodisch in über eine Steuerung veränderbaren Zeiten das Brennrohr kurz weitergedreht werden, um den Selbstreinigungseffekt aufrechtzuerhalten, es kann auch vor dem Zünden ein Entaschungszyklus durchgeführt werden, wo durch längeres Drehen des Brennrohres die Asche hinausbefördert wird.The drive of the combustion tube is independent of the drive of the fuel supply system, thereby not only during combustion periodically changeable over a control times, the burner tube can be further rotated briefly to maintain the self-cleaning effect, it can be carried out before the ignition a Entaschungszyklus, where by longer Turning the combustion tube, the ash is carried out.
Weiters können beim Abstellen des Brenners während des "Ausbrennens" die Drehzyklen so gesteuert werden, dass das im Brennrohr befindliche Brennmaterial vollständig verbrannt wird und keine Glutnester zurückbleiben, was die Gefahr von Rückbrand senkt, die Betriebssicherheit erhöht und den Wartungsaufwand erheblich reduziert.Furthermore, when turning off the burner during the "burnout" the rotation cycles can be controlled so that the combustion material located in the combustion tube is completely burned and no gassing left behind, which reduces the risk of burnback, increases the reliability and significantly reduces maintenance.
Durch die Anordnung aller Bauteile an und in einem tragenden geschlossenen Gehäuse entsteht nicht nur eine kompakte Brennereinheit, welche an jeden Ofen, Wärmetauscher oder Boiler angeflanscht werden kann, es entsteht durch das angeflanschte Gebläse ein Überdruck im Gehäuse, welcher ohne zusätzliche Luftführungsschläuche oder Luftführungseinrichtungen die Verbrennungsluft zu den einzelnen Lufteintrittsöffnungen des Brennrohres führt und gleichzeitig alle Bauteile kühlt, sodass der Brenner auch bei voller Leistung außen nicht heiß wird.The arrangement of all components on and in a supporting closed housing not only creates a compact burner unit, which can be flanged to any oven, heat exchanger or boiler, it is caused by the flanged fan overpressure in the housing, which without additional air ducts or air ducting the combustion air leads to the individual air inlet openings of the combustion tube and at the same time cools all components, so that the burner is not hot outside even at full power.
Das Brennluftgebläse ist vorzugsweise an eine Steuerung angeschlossen, wo die Luftleistung verändert werden kann, der Luftstrom kann aber auch durch Größe und Anordnung der einzelnen Lufteintrittsöffnungen verändert werden.The combustion air blower is preferably connected to a controller, where the air power can be changed, but the air flow can also be changed by the size and arrangement of the individual air inlet openings.

Durch eine Weiterdrehung des Brennrohres nach einer in Abhängigkeit von der verbrannten Brennstoffmenge einstellbaren Zeit um einen bestimmten Drehwinkel wird das Brennmaterial weiterbefördert und frisches Brennmaterial kann nachgefördert werden bzw. bei der Ausführung nach
Durch die periodische Weiterdrehung kann somit eine größere Leistung erzielt werden und gleichzeitig erfolgt eine Selbstreinigung des Brenners, da nicht nur die Asche hinausbefördert wird, sondern auch anhaftende Verbrennungsrückstände und Ablagerungen abgebrannt werden.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.
Durch zwei voneinander unabhängige Antriebe für Brennrohr und Brennstoffzuführungseinheit können Reinigungs- und Entaschungszyklen programmiert werden.With two independent drives for the combustion tube and fuel supply unit, cleaning and ash removal cycles can be programmed.
