Description

Die Erfindung betrifft einen Herd mit einem Pelletsbrenner und einem Brennraum.The invention relates to a stove with a pellet burner and a combustion chamber.

Ein derartiger Herd mit eine Pelletsbrenner ist beispielsweise aus der EP 1 022 512 A1 bekannt, in der ein Koch- bzw. Backherd gezeigt ist, der als einzige Energiequelle einen Pelletsbrenner aufweist, der in einem Brennraum angeordnet ist.Such a stove with a pellet burner is for example known from EP 1 022 512 A1, in which a cooking or Oven is shown as the only energy source one Has pellet burner, which is arranged in a combustion chamber.

Ebenso ist in der US 5 429 110 ein Herd gezeigt, der mittels Pelletsverbrennung beheizt wird. Um eine gleichmäßige Verbrennung sicherzustellen, ist eine automatische Pelletszufuhr über eine Fördereinrichtung und ein Gebläse vorgesehen.Likewise, in US 5 429 110 a stove is shown, which means Pellet combustion is heated. To ensure even combustion ensure an automatic pellet feed provided via a conveyor and a blower.

Auch in der US 4 989 521 A ist lediglich ein Herd mit einem Brennraum gezeigt, wobei der Herd über Pellets, Holzstücke getrocknetes Getreide oder dergleichen befeuert werden kann. Die Abluft des über einen Brenner beheizten Ofens wird hier einem Wärmetauscher zum Erwärmen von Wasserzugeführt.Also in US 4,989,521 A there is only one cooker with one Combustion chamber shown, the stove dried over pellets, pieces of wood Grain or the like can be fired. The Exhaust air from the furnace heated by a burner becomes one here Heat exchanger supplied for heating water.

Andererseits sind bereits zahlreiche Festbrennstoff-Herde bekannt, bei denen vorzugsweise Holzscheite als Brennstoff verwendet werden. Bei der Befeuerung eines derartigen Festbrennstoff-Herds durch Scheitholz kommt es durch die diskontinuierliche chargenweise Beschickung mit Brennmaterial zu einer sehr unregelmäßigen Wärmeleistung.On the other hand, there are already numerous solid fuel stoves known, where preferably logs as fuel be used. When firing such a solid fuel stove through logs it comes through the discontinuous batch loading of fuel into one very irregular heat output.

Ziel der vorliegenden Erfindung ist es nun, einen Herd der eingangs angeführten Art zu schaffen, bei dem auch die Verbrennung von anderen Brennstoffen als Pellets, insbesondere von Holzscheiten möglich ist, wobei die Verbrennung dieses weiteren Brennstoffs vergleichsweise kontinuierlich erfolgen soll und zudem stufenlos geregelt werden kann, so dass eine gegenüber bekannten Vorrichtungen vergleichsweise konstante Verbrennung und somit eine regelmäßigere Wärmeleistung erzielt werden kann.The aim of the present invention is now a stove to create the type mentioned, in which also the combustion of fuels other than pellets, especially of Logs are possible, the combustion of this further Fuel should take place comparatively continuously and also can be regulated continuously, so that a compared to known Devices comparatively constant combustion and thus a more regular heat output can be achieved.

Dies wird erfindungsgemäß mit einem Herd der eingangs angeführten Art dadurch erzielt, dass ein Herdbrennraum zur Aufnahme von Festbrennstoff, insbesondere von Holzbrennstoff, an den Pelletsbrenner derart anschließt, dass als Brennraum des Pelletsbrenners zumindest teilweise der Herdbrennraum vorgesehen ist. Durch das Vorsehen eines Pelletsbrenners, bei dem zumindest teilweise der Herdbrennraum zum Ausbrand der Pellets herangezogen wird, kann das im Herdbrennraum vorhandene Brennmaterial, z.B. Holzscheite, über den Pelletsbrenner entzündet werden und sobald die Verbrennung im Herdbrennraum eigenständig voranschreitet, die Leistung im Pelletsbrenner zurückgeregelt werden bzw. kann dieser vollständig ausgeschaltet werden. Hierdurch wird auf einfache Weise eine vergleichsweise konstante Verbrennung im Herdbrennraum des Festbrennstoff-Herds erzielt. Weiters kann durch den zuschaltbaren Pelletsbrenner eine stufenlose Temperaturregelung des Herds erfolgen.This is according to the invention with a stove of the type mentioned Art achieved by having a stove combustion chamber for inclusion of solid fuel, especially wood fuel, to the Pellet burner connected in such a way that the Pellet burner at least partially provided the stove combustion chamber is. By providing a pellet burner, at least partially the stove combustion chamber was used to burn out the pellets the fuel in the hearth combustion chamber, e.g. Logs that ignite pellet burners and as soon as the combustion in the stove combustion chamber independently progresses, the output in the pellet burner is reduced can or can be completely switched off. hereby becomes a comparatively constant in a simple manner Combustion in the hearth combustion chamber of the solid fuel stove achieved. Furthermore, the stepless pellet burner can be switched on and off Temperature control of the cooker take place.

Auf konstruktiv einfache Weise kann dies erlangt werden, in dem der Brennraum des Pelletsbrenners und der Herdbrennraum über einen Schacht miteinander verbunden sind. Bei einer derartigen Ausgestaltung können die Pellets in einem gesonderten Brennraum gezündet werden, wobei jedoch der eigentliche Ausbrand über den Schacht im Herdbrennraum des benachbarten Festbrennstoff-Herds erfolgt. Über den Pelletsbrenner können die in den Herdbrennraum des Festbrennstoff-Herds eingebrachten Holzscheite in Brand gesetzt werden bzw. das Hauptfeuer im Herdbrennraum - sofern dieses keine bzw. eine zu geringe Energiemenge produziert - unterstützt werden. Durch die Kombination des Abbrands von Pellets und Holzscheiten kann mit dem Festbrennstoff-Herd im Wesentlichen eine konstante Wärmemenge erzeugt werden.This can be achieved in a structurally simple manner, in over the combustion chamber of the pellet burner and the stove combustion chamber a shaft are connected to each other. With such a The pellets can be configured in a separate combustion chamber be ignited, but the actual burnout over the Shaft in the stove combustion chamber of the neighboring solid fuel stove he follows. You can use the pellet burner in the stove combustion chamber of the solid fuel stove brought on fire or the main fire in the hearth combustion chamber - if this produces no or too little energy - supports become. By combining the burning of pellets and logs can work with the solid fuel stove essentially a constant amount of heat is generated.

Um einen Herd auf einfache Weise mit einem Pelletsbrenner kombinieren zu können bzw. insbesondere auch eine nachträgliche Ausstattung eines Festbrennstoff-Herds mit einem Pelletsbrenner zu ermöglichen, ist es von Vorteil, wenn der Pelletsbrenner und der Festbrennstoff-Herd als gesonderte modulare Baueinheiten ausgebildet sind.To cook a stove easily with a pellet burner to be able to combine or in particular also a subsequent one Equipping a solid fuel stove with a pellet burner to enable it is advantageous if the pellet burner and the solid fuel stove as separate modular units are trained.

Um die jeweils gewünschte Menge an Pellets je nach der im Herdbrennraum durch den Abbrand der Holzscheite erzielten Wärmemenge zu einzubringen, ist es günstig, wenn der Pelletsbrenner eine Förderschnecke zum Einbringen von Pellets aus einem Vorratsbehälter in den Pelletsbrenner-Brennraum aufweist.To the desired amount of pellets depending on the in Stove combustion chamber generated by the burning of the logs to insert, it is convenient if the pellet burner a screw conveyor for introducing pellets from a storage container in the pellet burner combustion chamber.

Hierbei ist es vorteilhaft, wenn die Förderschnecke zur Hälfte ein linksgängiges Gewinde und zur Hälfte ein rechtsgängiges Gewinde aufweist, da somit zuverlässig Pellets von den Randbereichen der Förderschnecke in die Mitte transportiert werden, wo sie über einen Schacht in ihren eigentlichen Brennraum herabfallen. Zudem ist somit der gesamte Pelletsbrenner symmetrisch ausgestaltet, so dass ein Anschluss an beiden Seiten eines Festbrennstoff-Herds möglich ist, ohne dass hierzu - abhängig von der Anschluss-Seite - spezielle Teile erforderlich wären.It is advantageous if the screw conveyor for Half a left-hand thread and half a right-hand thread Thread, because thus reliable pellets from the Edge areas of the screw conveyor transported to the center where they have a shaft in their actual combustion chamber fall. It is also the entire pellet burner designed symmetrically, so that a connection on both sides solid fuel cooker is possible without - depending on the connection side - special parts required would.

Um die vom Pelletsbrenner erzeugte Wärmemenge auf einfache Weise an die diskontinuierliche Verbrennung im Herdbrennraum des Festbrennstoff-Herds anpassen zu können, ist es günstig, wenn eine Regeleinheit zur Leistungsregelung des Pelletsbrenners vorgesehen ist, wobei die Leistung des Pelletsbrenners über die zugeführte Pelletsmenge sowie die beispielsweise mittels eines Lüfters zur Verfügung gestellte Luft geregelt werden kann.To the amount of heat generated by the pellet burner on simple Way to the discontinuous combustion in the stove combustion chamber To be able to adapt solid fuel stoves, it is beneficial if a control unit for controlling the output of the pellet burner is provided, the performance of the pellet burner over the amount of pellets supplied and, for example, by means of a Air provided by the fan can be regulated.

Um im Herdbrennraum die gewünschte, möglichst konstante Temperatur einstellen zu können, ist es günstig, wenn im Herdbrennraum ein, der Regeleinheit zugeordneter Temperatursensor vorgesehen ist, da somit abhängig von der im Herdbrennraum gemessenen Temperatur die Leistung des Pelletsbrenners geregelt werden kann.To achieve the desired temperature in the stove combustion chamber that is as constant as possible To be able to adjust, it is convenient if in the stove combustion chamber a temperature sensor assigned to the control unit is provided is dependent on the one measured in the hearth combustion chamber Temperature the output of the pellet burner can be regulated can.

Wenn der Regeleinheit eine Zeitschaltung zugeordnet ist, kann zu vorgegebenen Zeiten eine selbsttätige Zündung des Festbrennstoff-Herdes über den Pelletsbrenner erfolgen.If a timer is assigned to the control unit, can automatically ignite the solid fuel stove at predetermined times via the pellet burner.

Wenn der Festbrennstoff-Herd primär zum Beheizen eines Raumes verwendet wird, ist es vorteilhaft, wenn der Regeleinheit ein Raumtemperatursensor zugeordnet ist, da somit die Regelung auf eine gewünschte Raumtemperatur erzielt werden kann.If the solid fuel stove is primarily used to heat a room is used, it is advantageous if the control unit a room temperature sensor is assigned, because the control can be achieved to a desired room temperature.

Wenn an den Festbrennstoff-Herd ein, vorzugsweise als modulare Baueinheit ausgebildeter, mit einer Heizung in Verbindung stehender Wärmetauscher anschließt, kann mit dem Pelletsbrenner, dem Festbrennstoff-Herd und diesem Wärmetauscher ein vollwertiges Heizsystem erzielt werden.When connected to the solid fuel stove, preferably as a modular Unit trained, in connection with a heater vertical heat exchanger can be connected to the pellet burner, the solid fuel stove and this heat exchanger is a fully fledged one Heating system can be achieved.

Da durch die im Vergleich zu bisher bekannten Festbrennstoff-Herden erzielte im Wesentlichen konstante Wärmeabgabe der Festbrennstoff-Herd, insbesondere auch zum Braten bzw. Backen von Lebensmittel geeignet ist, ist es günstig, wenn an den Festbrennstoff-Herd ein, vorzugweise als modulare Baueineit ausgebildetes, vom Festbrennstoff-Herd beheiztes Backrohr anschließt.As a result of the solid fuel stoves known to date achieved essentially constant heat emission from the Solid fuel stove, especially for roasting or baking of food is suitable, it is convenient if attached to the solid fuel stove a, preferably designed as a modular construction unit, oven heated by the solid fuel stove.

Hierbei ist es hinsichtlich einer möglichst konstanten Temperatur im Backrohr von Vorteil, wenn im Backrohr ein der Regeleinheit zugeordneter Temperatursensor vorgesehen ist.It is here that the temperature is as constant as possible an advantage in the oven if there is a control unit in the oven assigned temperature sensor is provided.

Die Erfindung wird nachstehend anhand von einem in der Zeichnung dargestellten bevorzugten Ausführungsbeispiel, auf das sie jedoch nicht beschränkt sein soll, noch weiter erläutert. Im Einzelnen zeigen in der Zeichnung:

  • Fig. 1 eine perspektivische Ansicht eines Festbrennstoff-Herds mit angeschlossenem Pelletsbrenner und Backrohr;
  • Fig. 2 eine Frontalansicht des Festbrennstoff-Herds gemäß Fig. 1;

  • Fig. 5 ein Schnittbild der Verbindung zwischen Pelletsbrenner und Festbrennstoff-Herd entlang der Linie V-V in Fig. 3.
    • The invention is explained in more detail below with reference to a preferred exemplary embodiment shown in the drawing, to which, however, it should not be limited. The drawing shows in detail:
  • Figure 1 is a perspective view of a solid fuel stove with connected pellet burner and oven.
  • FIG. 2 shows a frontal view of the solid fuel stove according to FIG. 1;

  • Fig. 4 is a sectional view through the solid fuel stove along the line IV-IV in Fig. 2, and
  • 5 is a sectional view of the connection between the pellet burner and solid fuel stove along the line VV in Fig. 3rd

    • In den Figuren 1 und 2 ist ein Festbrennstoff-Herd 1 ersichtlich, an den seitlich ein Pelletsbrenner 2 anschließt. Mit Hilfe des Pelletsbrenners 2 kann das in einen Herdbrennraum 3 eingebrachte Brennmaterial, insbesondere Holzscheite, gezündet werden, da ein Brennraum 4 des Pelletsbrenners 2 über einen Schacht 5 mit dem Herdbrennraum 3 verbunden ist, wodurch der vollständige Ausbrand der Pellets erst im Herdbrennraum 3 erfolgt. Über den Pelletsbrenner 2 kann somit sowohl eine Zündung der im Herdbrennraum 3 vorhandenen Holzscheite als auch eine den Ausbrand im Festbrennstoff-Herd 1 unterstützende Funktion erzielt werden, wodurch eine vergleichsweise konstante Wärmeleistung abgegeben werden kann.A solid fuel stove 1 can be seen in FIGS. 1 and 2, to which a pellet burner 2 is connected on the side. With With the help of the pellet burner 2, this can be placed in a stove combustion chamber 3 brought fuel, especially logs, ignited be because a combustion chamber 4 of the pellet burner 2 over a Shaft 5 is connected to the stove combustion chamber 3, whereby the The pellets are only completely burned out in the stove combustion chamber 3. The pellet burner 2 can thus both ignite the existing logs in the stove combustion chamber 3 as well as one Burnout in the solid fuel stove 1 supporting function achieved be, resulting in a comparatively constant heat output can be delivered.

    Der Schacht 5 zur Verbindung des Brennraums 4 des Pelletsbrenners 2 mit dem Herdbrennraum 3 ist beispielsweise mit Steinen ausgekleidet und weist an seiner Oberseite mehrere Unterbrechungen 6 auf (vgl. Fig. 4), um ein vollständiges Verlegen der Schachtöffnung mit Holzscheiten zuverlässig zu verhindern.The shaft 5 for connecting the combustion chamber 4 of the pellet burner 2 with the stove combustion chamber 3 is for example with Lined stones and has several breaks on its top 6 on (see Fig. 4) to complete laying to reliably prevent the shaft opening with logs.

    Wie insbesondere in den Figuren 2 und 5 ersichtlich ist, weist der Pelletsbrenner 2 einen Vorratsbehälter 7 auf, in dem beispielsweise 20 kg Pellets aufgenommen werden können. 1 kg dieses CO2- neutralen Brennstoffes enthält ca. 4,9 kWh, so dass bei 3 kW Leistungsabgabe der Vorrat für ca. 24 h reicht. Die Pellets werden von dem Vorratsbehälter 7 über einen Schacht mittels der Schwerkraft in Richtung einer Förderschnecke 8 gefördert, wobei die Förderschnecke 8 zur Hälfte ein linksgängiges und zur Hälfte ein rechtsgängiges Gewinde aufweist, so dass Pellets von den äußeren Rändern des Schachts des Vorratsbehälters 7 in die Mitte transportiert werden, wo sie dem Pelletsbrennraum 4 über einen Schacht 7' zugeführt werden. Die in den Brennraum 4 eingebrachten Pellets fallen somit auf einen Rost 4', auf dem sie entzündet werden.As can be seen in particular in FIGS. 2 and 5, the pellet burner 2 has a storage container 7 in which, for example, 20 kg of pellets can be accommodated. 1 kg of this CO 2 - neutral fuel contains approx. 4.9 kWh, so that with 3 kW of power output, the supply lasts for approx. 24 h. The pellets are conveyed from the storage container 7 via a shaft by means of gravity in the direction of a screw conveyor 8, the screw conveyor 8 having a left-handed thread and half a right-handed thread, so that pellets from the outer edges of the shaft of the storage container 7 into the Center are transported, where they are fed to the pellet combustion chamber 4 via a shaft 7 '. The pellets introduced into the combustion chamber 4 thus fall onto a grate 4 'on which they are ignited.

    Unterhalb des Rosts 4 des Pelletsbrenners 2 ist eine Aschelade 9 für das verbrannte Pelletsmaterial vorgesehen. There is an ash drawer below the grate 4 of the pellet burner 2 9 provided for the burned pellet material.

    Die Leistung des Pelletsbrenners 2 kann stufenlos beispielsweise zwischen 2,5 kW und 8 kW geregelt werden, wobei zur Zündung von im Herdbrennraum 3 angeordneten Holzscheiten der Pelletsbrenner 2 für einen kurzen Zeitraum von beispielsweise 10 min. durch eine erhöhte Luftzufuhr und eine vermehrte Pelletszufuhr mit einer Leistung von beispielsweise 16 kW betrieben werden kann. Durch die doppelte Leistung wird somit zuverlässig gewährleistet, dass die Flamme vom Pelletsbrenner 2 über den Schacht 5 in den Herdbrennraum 3 hineinreicht, so dass die Holzscheite in Brand gesetzt werden können. Sobald die Holzscheite brennen, kann der Pelletsbrenner 2 zurückgeregelt bzw. vollkommen ausgeschaltet werden.The output of the pellet burner 2 can be infinitely variable, for example between 2.5 kW and 8 kW can be regulated, whereby for ignition of arranged in the stove combustion chamber 3 logs Pellet burner 2 for a short period of time, for example 10 min. through an increased air supply and an increased Pellet feed operated with an output of 16 kW, for example can be. The double performance makes it reliable ensures that the flame from the pellet burner 2 reaches into the stove combustion chamber 3 via the shaft 5, so that the logs can be set on fire. Once the logs burn, the pellet burner 2 can be reduced or be completely switched off.

    Die Förderschnecke 8 wird von einem Motor 10 (vgl. Fig. 3) angetrieben, der ebenso wie ein Lüfter (nicht gezeigt) einer Regeleinheit zugeordnet ist, über welche die Leistung des Pelletsbrenner 2 geregelt werden kann.The screw conveyor 8 is driven by a motor 10 (see FIG. 3) driven, just like a fan (not shown) one Control unit is assigned, via which the performance of the Pellet burner 2 can be regulated.

    Als Stellgröße für die Leistungsregelung wird entweder die Temperatur im Herdbrennraum 3 oder in der Umgebung, welche mittels geeigneten Sensoren gemessen werden, herangezogen. Ebenso kann in einem an den Festbrennstoff-Herd 1 anschließenden Backrohr 11 die über einen Sensor gemessene Temperatur zur Regelung der Leistung des Pelletsbrenners 2 herangezogen werden, um im Backrohr 11 eine möglichst konstante Temperatur zu erlangen.Either the Temperature in the stove combustion chamber 3 or in the area, which means suitable sensors are measured. As well can in an oven connected to the solid fuel stove 1 11 the temperature measured via a sensor for regulation the power of the pellet burner 2 to be used in To achieve oven temperature 11 as constant as possible.

    Anstelle des Backrohrs 11 könnte beispielsweise auch ein Wärmetauscher (nicht gezeigt), der mit einer Heizung, beispielsweise einer Zentralheizung, in Verbindung steht, vorgesehen werden, wodurch zusammen mit einem Thermostat ein vollwertiges Heizsystem erzielt werden kann.Instead of the oven 11 could, for example Heat exchanger (not shown) using a heater, for example central heating, is provided be, which together with a thermostat a full Heating system can be achieved.

    Um den Festbrennstoff-Herd 1 auf einfache Weise mit dem Pelletsbrenner 2, dem Backrohr 11 oder einem Wärmetauscher (nicht gezeigt) zu kombinieren, sind der Pelletsbrenner 2, das Backrohr 11 bzw. der Wärmetauscher als gesonderte Baueinheiten modular ausgestaltet.To the solid fuel stove 1 in a simple way with the Pellet burner 2, the oven 11 or a heat exchanger To combine (not shown) are the pellet burner 2, the Oven 11 or the heat exchanger as separate units modular design.

    Alternativ oder zusätzlich zu der von einer gemessenen Temperatur abhängigen Leistungsregelung des Pelletsbrenners 2 kann diesem auch eine Zeitschaltuhr zugeordnet sein, wodurch zu einer vorbestimmten Zeit zunächst der Pelletsbrenner 2 gezündet werden kann. Mittels dem über den Schacht 5 in den Herdbrennraum 3 hineinragenden Ausbrand der Pellets werden die im Herdbrennraum 3 vorgesehenen Holzscheite gezündet. Der Pelletsbrenner 2 kann darauffolgend wieder zurückgeregelt bzw. vollkommen ausgeschaltet werden.Alternatively or in addition to that of a measured temperature dependent power control of the pellet burner 2 can this also be assigned a timer, which leads to a predetermined time, the pellet burner 2 are first ignited can. By means of the protruding into the stove combustion chamber 3 via the shaft 5 The pellets are burned out in the stove combustion chamber 3 provided intended logs ignited. The pellet burner 2 can subsequently regulated back or completely switched off become.
