Description
Die Erfindung betrifft eine Heizvorrichtung.The invention relates to a heating device.
Derartige Heizvorrichtungen können generell als Warmwasserheizungen oder auch als Vorrichtungen zur Erzeugung von Warmluft ausgebildet sein, die in Gebäuden unterschiedlicher Bauart zum Einsatz kommen können.Such heating devices can generally be designed as hot water heaters or as devices for generating warm air, which can be used in buildings of different types.
Eine derartige Heizvorrichtung umfasst generell eine Brennkammer. In dieser Brennkammer ist das zu erhitzende Medium wie Wasser oder Luft in Leitungen geführt. Zur Erhitzung des Mediums ist ein Brenner vorgesehen. Der Brenner ist in einer Wand der Brennkammer so montiert, dass eine mit dem Brenner erzeugte Flamme in den Innenraum der Brennkammer gerichtet ist und so das Medium in den Leitungen erhitzt. Die Leitungen sind aus der Brennkammer herausgeführt, um so das erhitzte Medium Heizkörpern oder dergleichen zuzuführen.Such a heating device generally comprises a combustion chamber. In this combustion chamber, the medium to be heated, such as water or air, is guided in pipes. A burner is provided to heat the medium. The burner is mounted in a wall of the combustion chamber in such a way that a flame generated by the burner is directed into the interior of the combustion chamber and thus heats the medium in the pipes. The pipes are led out of the combustion chamber in order to supply the heated medium to radiators or the like.
Üblicherweise ist der Brenner der Heizvorrichtung so ausgeführt, dass er nur mit einem bestimmten Brennstoff betrieben werden kann.Usually, the burner of the heating device is designed in such a way that it can only be operated with a specific fuel.
Weiterhin ist es bekannt eine derartige Heizvorrichtung mit einem Zweistoff-Brenner zu betreiben. Ein Vorteil hierbei besteht darin, dass ein solcher Zweistoff-Brenner wahlweise mit zwei unterschiedlichen Brennstoffen betrieben werden kann, was die Flexibilität der Heizvorrichtung erhöht.It is also known to operate such a heating device with a dual-fuel burner. One advantage of this is that such a dual-fuel burner can be operated with two different fuels, which increases the flexibility of the heating device.
Nachteilig hierbei ist jedoch der konstruktiv sehr aufwändige Aufbau von Zweistoff-Brennern.The disadvantage here, however, is the very complex construction of dual-fuel burners.
Zudem werden derartige Zweistoff-Brenner ausschließlich im industriellen Bereich eingesetzt und können von Heizungsbauern bzw. Heizungsmonteuren, die Heizungen in Privathäusern installieren und warten, nicht betreut werden.In addition, such dual-fuel burners are used exclusively in the industrial sector and cannot be serviced by heating engineers or heating fitters who install and maintain heating systems in private homes.
Der Erfindung liegt die Aufgabe zugrunde eine Heizvorrichtung bereitzustellen, die einen konstruktiv einfachen Aufbau und zugleich eine hohe Funktionalität aufweist.The invention is based on the object of providing a heating device which has a structurally simple design and at the same time a high level of functionality.
Zur Lösung dieser Aufgabe sind die Merkmale der unabhängigen Ansprüche vorgesehen. Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The features of the independent claims are intended to solve this problem. Advantageous embodiments and expedient developments of the invention are described in the dependent claims.
Die erfindungsgemäße Heizvorrichtung umfasst eine Brennkammer in welcher ein Medium vorhanden ist und eine Brenneranordnung mittels derer das Medium beheizt wird. Die Brenneranordnung weist wenigstens zwei Brenner auf, die mit unterschiedlichen Brennstoffen betrieben sind. Eine Schalteinheit ist vorhanden, mittels derer die Brenner selektiv aktivierbar sind.The heating device according to the invention comprises a combustion chamber in which a medium is present and a burner arrangement by means of which the medium is heated. The burner arrangement has at least two burners which are operated with different fuels. A switching unit is provided by means of which the burners can be selectively activated.
Die Erfindung betrifft weiterhin ein entsprechendes Verfahren.The invention further relates to a corresponding method.
Bei der erfindungsgemäßen Heizvorrichtung werden zur Aufheizung eines Mediums in der Brennkammer mindestens zwei Brenner eingesetzt, die über die Schalteinheit selektiv aktiviert werden können.In the heating device according to the invention, at least two burners are used to heat a medium in the combustion chamber, which burners can be selectively activated via the switching unit.
Dabei ist wesentlich, dass die Brenner mit unterschiedlichen Brennstoffen betrieben werden.It is essential that the burners are operated with different fuels.
Die Brenneranordnung bildet damit ein diversitär redundantes System, das die Flexibilität und Verfügbarkeit der Heizvorrichtung erhöht.The burner arrangement thus forms a diversely redundant system that increases the flexibility and availability of the heating device.
Mit der erfindungsgemäßen Brenneranordnung wird insbesondere die Ausfallsicherheit der Heizvorrichtung erhöht. Besonders vorteilhaft wird mittels der Schalteinheit derjenige Brenner aktiviert, für welchen Brennstoffe verfügbar sind. Ist beispielsweise durch Versorgungsengpässe oder dergleichen ein Brennstoff für einen Brenner nicht verfügbar, wird mit den Schaltmitteln der andere Brenner aktiviert, dessen Brennstoff verfügbar ist, so dass unerwünschte Stillstände der Raumheizungseinrichtung vermieden werden.The burner arrangement according to the invention particularly increases the reliability of the heating device. Particularly advantageously, the switch unit activates the burner for which fuel is available. If, for example, a fuel for a burner is not available due to supply bottlenecks or the like, the switching means activate the other burner whose fuel is available, so that undesirable downtimes of the space heating system are avoided.
Da die Wahrscheinlichkeit, dass beide Brennstoffmedien für die Brenneranordnung gleichzeitig nicht verfügbar sind, gering ist, ist die Wahrscheinlichkeit eines Ausfalls der Raumheizungseinrichtung sehr gering.Since the probability that both fuel media for the burner assembly are not available at the same time is low, the probability of failure of the space heating system is very low.
Ein weiterer Vorteil besteht darin, dass für die Brenneranordnung herkömmliche Brenner eingesetzt werden können, die jeweils nur mit einem Brennstoff betrieben werden. Im Gegensatz zur Brenneranordnung mit aufwändigen Zweistoff-Brennern ergibt sich somit eine konstruktive Vereinfachung. Zudem ist vorteilhaft, dass die Brenneranordnung mit ihren konventionellen Brennern von Heizungsbauern d.h. lokalen Handwerksbetrieben, betreut und gewartet werden kann.Another advantage is that conventional burners can be used for the burner arrangement, each of which is operated with only one fuel. In contrast to the burner arrangement with complex dual-fuel burners, this results in a structural simplification. Another advantage is that the burner arrangement with its conventional burners can be serviced and maintained by heating engineers, i.e. local tradesmen.
In ihrer einfachsten Konfiguration weist die erfindungsgemäße Heizvorrichtung zwei Brenner auf, die mit unterschiedlichen Brennstoffen betrieben werden. Dadurch, dass die Brenner mit unterschiedlichen Brennstoffen betrieben werden, wird die Abhängigkeit der Heizvorrichtung von einem einzigen Brennstoff beseitigt und die Verfügbarkeit der Heizvorrichtung erhöht.In its simplest configuration, the heating device according to the invention has two burners that are operated with different fuels. By operating the burners with different fuels, the dependence of the heating device on a single fuel is eliminated and the availability of the heating device is increased.
Die erfindungsgemäße Heizvorrichtung kann auch mehr als zwei Brenner aufweisen. In diesem Fall können alle Brenner mit unterschiedlichen Brennstoffen betrieben werden, wodurch die Abhängigkeit von einem Brennstoff noch weiter reduziert wird. Alternativ können Gruppen von Brennern, beispielsweise zwei Brenner, mit dem gleichen Brennstoff betrieben werden, wobei unterschiedliche Gruppen von Brennern oder andere einzelne Brenner mit unterschiedlichen Brennstoffen betrieben werden. Die Gruppen von Brennern, die mit gleichen Brennstoffen betrieben werden, bilden dann homogen redundante Teilsysteme innerhalb des diversitär redundanten Gesamtsystems, die zu einer weiteren erhöhten Ausfallsicherheit führen.The heating device according to the invention can also have more than two burners. In this case, all burners can be operated with different fuels, thereby further reducing the dependence on one fuel. Alternatively, groups of burners, for example two burners, can be operated with the same fuel, with different groups of burners or other individual burners being operated with different fuels. The groups of burners that are operated with the same fuels then form homogeneously redundant subsystems. within the diversely redundant overall system, which leads to further increased reliability.

Insbesondere werden als gasförmige Brennstoffe Erdgas, Biogas, Flüssiggas oder Wasserstoff eingesetzt.In particular, natural gas, biogas, liquefied petroleum gas or hydrogen are used as gaseous fuels.
Weiterhin ist es möglich, dass die Brenner der Brenneranordnung mit flüssigen Brennstoffen betrieben werden.Furthermore, it is possible for the burners of the burner arrangement to be operated with liquid fuels.
Insbesondere werden als flüssige Brennstoffe Heizöl, Biodiesel, Kerosin oder LOHC (liquid organic hydrogen carriers) eingesetzt.In particular, heating oil, biodiesel, kerosene or LOHC (liquid organic hydrogen carriers) are used as liquid fuels.
Gemäß einer vorteilhaften Ausführungsform ist mittels der Schalteinheit jeweils nur ein Brenner aktiviert.According to an advantageous embodiment, only one burner is activated at a time by means of the switching unit.
Die Auswahl des aktivierten Brenners erfolgt insbesondere nach dem Kriterium der Verfügbarkeit der Brennstoffe für die einzelnen Brenner.The selection of the activated burner is made in particular according to the criterion of the availability of fuel for the individual burners.
Gemäß einer alternativen Ausgestaltung sind mittels der Schalteinheit mehrere Brenner gleichzeitig aktiviert.According to an alternative embodiment, several burners are activated simultaneously by means of the switching unit.
In diesem Fall können die aktivierten Brenner mit reduzierten Leistungsstufen betrieben werden.In this case, the activated burners can be operated at reduced power levels.
Generell ist es möglich die Leistungsstufen des oder der aktivierten Brenner zu variieren und an die Anforderungen der Heizvorrichtung anzupassen.In general, it is possible to vary the power levels of the activated burner(s) and adapt them to the requirements of the heating device.
Vorteilhaft werden mittels der Schalteinheit Leistungsstufen von aktivierten Brennern vorgegeben.Advantageously, the switching unit is used to specify the power levels of activated burners.
Dabei können generell die Leistungsstufen abhängig von der Anzahl simultan aktivierter Brenner sein.In general, the power levels can depend on the number of burners activated simultaneously.
Gemäß einer ersten Variante wird mit der Schalteinheit eine manuelle Brenneraktivierung durchgeführt.According to a first variant, manual burner activation is carried out using the switching unit.
In diesem Fall weist die Schalteinheit einen manuell betätigbaren Wahlschalter auf.In this case, the switching unit has a manually operated selector switch.
Gemäß einer zweiten Variante wird mit der Schalteinheit eine automatische Brenneraktivierung durchgeführt.According to a second variant, automatic burner activation is carried out using the switching unit.
Zweckmäßig wird dann die Schalteinheit von einer Steuereinheit gesteuert.The switching unit is then conveniently controlled by a control unit.
In diesem Fall kann in der Steuereinheit ein Ablaufprogramm implementiert sein, mittels dessen die Brenneraktivierung automatisch durchgeführt wird.In this case, a sequence program can be implemented in the control unit by means of which the burner activation is carried out automatically.
Mit dem Ablaufprogramm können beispielsweise Kontrollgrößen, Sensorsignale und dergleichen ausgewertet werden, die Informationen über die Verfügbarkeit der Brennstoffe liefern, wobei dann abhängig von diesen Informationen die Brennerumschaltung selbsttätig durchgeführt werden kann.The sequence program can be used, for example, to evaluate control variables, sensor signals and the like that provide information about the availability of fuels, whereby the burner switchover can then be carried out automatically depending on this information.
Die erfindungsgemäße Heizvorrichtung kann generell eine Warmluftheizung, Warmwasserheizung oder dergleichen ausbilden.The heating device according to the invention can generally form a warm air heating system, a warm water heating system or the like.
Dementsprechend ist das aufzuheizende Medium Wasser, Luft oder ein sonstiges Fluid.Accordingly, the medium to be heated is water, air or another fluid.
Generell wird das Medium in Leitungen in der Brennkammer geführt.Generally, the medium is guided in pipes in the combustion chamber.
Vorteilhaft weist die Brennkammer einen Kamin zur Ausleitung von Abgasen auf.Advantageously, the combustion chamber has a chimney for the discharge of exhaust gases.
