Description

Die Erfindung betrifft eine Brenner einheit, insbesondere für einen Herd, eine Warmluftheizung und/oder für die Warmwasseraufbereitung auf Yachten, in Wohnwagen, -mobilen, Zeiten od. dgl., mit einer Brennstoffzuführung über eine Leitung, die an einen Brennstofftank angeschlossen ist, in der sich zumindest ein Absperrorgan für den Brennstoff befindet, auf das eine Düse od. dgl. folgt.The invention relates to a burner unit, in particular for a stove, hot air heating and / or for hot water preparation on yachts, in caravans, mobile homes, times or the like, with a fuel supply via a line which is connected to a fuel tank, in which is at least one shut-off device for the fuel, followed by a nozzle or the like.

Yachten, Wohnwägen, Wohnmobile od. dgl. Einrichtungen sind heute mit leicht zu transportierenden Anlagen zur Wärmeerzeugung in vielfältiger Form bestückt. Dabei werden nicht nur ganze Kocheinrichtungen mitgeliefert, sondern auch Heizungsanlagen und Warmwasseraufbereitungsanlagen, beispielsweise für Duschzellen. All diese Wärmeerzeugungsanlagen benötigen Brenner, welche mit Gas, Petroleum, Dieselöl od. dgl. arbeitet. Vom Gas, welches leicht entzündbar ist und bei welchem deshalb das Anlassen des Brenners kein Problem darstellt, wird inzwischen Abstand genommen, da das Gas sehr viele Gefahren in sich birgt. Nicht nur das unbeabsichtigte Entweichen von Gas sondern auch die Benutzung von Gasflaschen in warmen Ländern hat in der Vergangenheit viele Opfer gefordert. Zudem muß neben dem eigentlichen Kraftstoff für den Betrieb der Yacht, des Wohnmobils oder einer Zugeinrichtung ein zusätzliches Behältnis für den Brennstoff für die Wärmeerzeugungsanlage mit sich geführt werden.Yachts, caravans, mobile homes or similar facilities are now equipped with easily transportable heat generation systems in a variety of forms. Not only entire cooking facilities are included, but also heating systems and hot water preparation systems, for example for shower cubicles. All of these heat generation systems require burners which work with gas, petroleum, diesel oil or the like. The gas, which is highly flammable and for which starting the burner is therefore not a problem, has since been abandoned, since the gas entails many dangers. Not only the unintentional escape of gas, but also the use of gas cylinders in warm countries has claimed many victims in the past. In addition to the actual fuel for the operation of the yacht, the motor home or a towing device, an additional container for the fuel for the heat generation system must be carried with it.

Deshalb werden üblicherweise die heute verwendeten Brenner für die o.g. Einrichtungen mit Petroleum oder Dieselkraftstoff betrieben. Damit der Brenner aber anläuft, bedarf es hier einer Vorwärmschale, in die vor der Zuleitung des eigentlichen Brennstoffes ein leicht entflammbarer Stoff, beispielsweise Brennspiritus, eingegossen und entzündet wird. Wenn dieser Stoff fast abgebrannt und die Vorwärmschale genügend erwärmt ist, wird die Zuleitung des eigentlichen Brennstoff geöffnet. Die Bestimmung des Zeitpunktes der Zuleitung des Brennstoffes birgt aber sehr viele Unsicherheiten in sich, so daß der Zündvorgang oftmals wiederholt werden muß. Wird aber in eine bereits vorgewärmte Vorwärmschale nochmals Brennspiritus eingegeben, so kann sich dieser explosionsartig entzünden und zu Verbrennungen führen.Therefore, the burners used today for the above are usually Facilities operated with petroleum or diesel fuel. So that the burner starts up, however, a preheating bowl is required, into which an easily flammable substance, for example methylated spirit, is poured and ignited before the actual fuel is fed. When this substance has almost burned down and the preheating tray has warmed up sufficiently, the feed line for the actual fuel is opened. However, the determination of the point in time at which the fuel is supplied harbors a great deal of uncertainty, so that the ignition process must often be repeated. However, if more alcohol is added to an already preheated preheating pan, this can ignite explosively and lead to burns.

Ferner ist aus der DE-A 28 08 918 eine Brennereinrichtung bekannt, welche an einen Brennstofftank über eine Leitung angeschlossen ist, in der sich zumindest ein Absperrorgan für den Brennstoff befindet. Im Betrieb dieses Verdampfungsbrenners wird Gas in flüssigem Zustand durch die Zufuhrleitung Rohrschlangen-Paketen zugeführt, die als Verdampfungsräume dienen. Aus den Rohrschlangen-Paketen strömt der Brennstoff in gasförmigem Zustand über eine Abfuhrleitung bei geöffnetem Regelventil in ein Verteilerrohr, aus dem der Brennstoff durch Düsen in Brennkammern strömt. Hierbei wird somit ein Gas im flüssigen Zustand verwendet, welches in Verdampfungsräumen wieder in gasförmigen Zustand versetzt wird. Ein Betrieb dieser Brenneinrichtung mit flüssigem Brennstoff ist nicht möglich. Gasförmige Brennstoffe bergen aber erhebliche Gefahren in sich, da sie viel leichter explosionsartig entzündbar sind.Furthermore, from DE-A 28 08 918 a burner device is known which is connected to a fuel tank via a line in which there is at least one shut-off element for the fuel. In the operation of this evaporation burner, gas in the liquid state is fed through the supply line to coils which serve as evaporation spaces. In the gaseous state, the fuel flows out of the pipe coil packages via a discharge line with the control valve open into a distributor pipe, from which the fuel flows through nozzles in combustion chambers. Here, a gas in the liquid state is used, which is brought back into the gaseous state in evaporation rooms. It is not possible to operate this burner with liquid fuel. Gaseous fuels, however, involve considerable dangers because they are much easier to ignite explosively.

Der Erfinder hat sich zum Ziel gesetzt, eine Vorrichtung der o.g. Art zu entwickeln, bei der ein Brennstoff benutzt werden kann, welcher entweder bereits anderweitig zum Transport bzw. der Bewegung der Einrichtung benutzt und relativ ungefährlich zu handhaben ist und bei dem zudem die Entzündung des Brennstoffes sicher, ungefährlich und automatisch erfolgt.The inventor has set himself the goal of developing a device of the type mentioned above using a fuel can be, which is already used otherwise for transport or the movement of the device and is relatively safe to use and which also ignites the fuel safely, safely and automatically.

Zur Lösung dieser Aufgabe führt, daß an die Leitung vor dem Absperrorgan zumindest eine Heizeinrichtung angelegt ist, wobei vor dem Entzünden der Brennstoff verdampft und Mittel zum Abschalten der Heizanlage nach dem Zünden vorhanden sind.To achieve this object, at least one heating device is applied to the line in front of the shut-off device, the fuel evaporating before ignition and means for switching off the heating system after ignition are available.

Befindet sich ein Brennstoff, wie beispielsweise Petroleum, Dieselöl od.dgl.,in der Leitung vor dem Absperrorgan, so wird durch die Wärme dieser zumindest teilweise in einen gasförmigen Aggregatzustand versetzt, in welchem der Brennstoff leicht entzündbar ist. Dabei sammelt sich das Gas unterhalb des Absperrorgans an, wobei der flüssige Brennstoff zumindest teilweise in den Tank zurückgedrückt wird. Nach Öffnen des Absperrorgans entweicht in erster Linie das leichter zu entzündende Gas, das dann die Düse umgebenden Elemente vorwärmen kann. Der dem Gas nachfolgende flüssige Brennstoff setzt dann unbeeinträchtigt die Tätigkeit des Brenners fort.If a fuel, such as petroleum, diesel oil or the like, is in the line in front of the shut-off element, the heat will at least partially bring it into a gaseous state in which the fuel is highly flammable. The gas collects below the shut-off element, the liquid fuel being at least partially pushed back into the tank. After opening the shut-off device, the gas that is more easily ignited primarily escapes and can then preheat the elements surrounding the nozzle. The liquid fuel following the gas then continues the activity of the burner unimpeded.

Im Rahmen der Erfindung soll unter dem Anlegen der Heizvorrichtung auch verstanden werden, daß die Heizvorrichtung in der Zuleitung selbst angeordnet werden kann. Allerdings ist dann ihre Handhabung, beispielsweise bei einem Ersatz, erschwert.In the context of the invention, the application of the heating device should also be understood to mean that the heating device itself can be arranged in the feed line. However, handling them, for example when replacing them, is then more difficult.

Die Leitungsteile, welche mit der Heizeinrichtung in Kontakt gebracht werden, sollten auf jeden Fall aus einem gut wärmeleitfähigen Material beispielsweise aus einem Metall bestehen.The line parts which are brought into contact with the heating device should in any case consist of a highly thermally conductive material, for example of a metal.

Je geringer der Durchmesser der Leitung ist, welche den zu erwärmenden Brennstoff in sich führt, um so schneller erfolgt die Erwärmung. Deshalb hat es sich als günstig erwiesen, die eigentliche Hauptleitung, die zudem meist ein flexibler Schlauch ist, in Zweigleitungen geringeren Durchmessers aufzuspalten, wobei die letzteren als Teil des Brenners hergestellt und aus Metall sein können. An diese Zweigleitung schließt dann auch die Heizeinrichtung an.The smaller the diameter of the line which contains the fuel to be heated, the faster the heating takes place. It has therefore proven advantageous to split the actual main line, which is usually also a flexible hose, into branch lines of smaller diameter, the latter being made as part of the burner and made of metal. The heating device then also connects to this branch line.

Um nun den Brenner wegen der Zweigleitung nicht zu groß werden zu lassen und um eine Vorwärmung des heranzuführenden Brennstoffes auch während der eigentlichen Tätigkeit des Brenners nach der Anfahrphase zu gewährleisten, werden Teile der Zweigleitung, nämlich Queräste nahe der Brennzone geführt.In order to prevent the burner from becoming too large due to the branch line and to ensure that the fuel to be preheated even during the burner's actual activity after the start-up phase, parts become the branch line, namely led cross branches near the firing zone.

Sobald das Gas aus der Düse entweicht, kann es mit einem Streichholz od.dgl. entzündet werden. Bevorzugt wird jedoch eine automatisch arbeitende Zündanlage, welche am besten einen intermittierenden Zündfunken erzeugt. Hier genügt beispielsweise eine Zündkerze, welche nahe der Düse festliegt und mit einer Batterie des Zugfahrzeuges oder Motors verbunden ist.As soon as the gas escapes from the nozzle, it can be matched or the like. be ignited. However, an automatically operating ignition system is preferred which best generates an intermittent ignition spark. Here, for example, a spark plug is sufficient, which is fixed near the nozzle and is connected to a battery of the towing vehicle or engine.

Als geeignete Brenner für die vorliegende Erfindung werden solche betrachtet, die bereits auf dem Markt erhältlich sind und bei denen die Zweigleitungen eine Vorwärmschale halten bzw. tragen in der ein Flammenverteiler sitzt. Derartige Brenner haben bereits geeignete Absperrorgane und Düsen, so daß nur die Heizeinrichtung angelegt und die Zündanlage zugeordnet werden muß.Suitable burners for the present invention are considered to be those which are already available on the market and in which the branch lines hold or carry a preheating shell in which a flame distributor is seated. Such burners already have suitable shut-off devices and nozzles, so that only the heating device has to be applied and the ignition system has to be assigned.

In einem weiteren verbesserten Ausführungsbeispiel wird die Zündanlage über die Temperatur bzw. die Zeit der Vorwärmung gesteuert.In a further improved exemplary embodiment, the ignition system is controlled via the temperature or the time of preheating.

Der erfindungsgemäße Brenner kann nun sehr wirkungsvoll mit bereits mitgeführten Brennstoffen bzw. im normalen Aggregatzustand relativ ungefährlichen Brennstoffen arbeiten. Das Entzünden erfolgt vollautomatisch, lediglich das Absperrventil muß geöffnet werden. Auch dies kann allerdings anhand einer Steuerung über die Temperatur oder die Zeit der Vorwärmung durch die Heizeinrichtung erfolgen. Der handelsübliche Brenner bedarf nur weniger Zusatzelemente und ist deshalb sehr wirtschaftlich umzurüsten.The burner according to the invention can now work very effectively with fuels already carried or with fuels that are relatively harmless in the normal state of aggregation. Ignition takes place fully automatically, only the shut-off valve has to be opened. However, this can also be done by controlling the temperature or the time of preheating by the heating device. The commercially available burner requires only a few additional elements and is therefore very economical to convert.

Der Brenner ist im Rahmen der Erfindung auch einsetzbar für die Erwärmung kleinerer Wohneinheiten, wobei er hier in geeignete Wärmkörper eingesetzt werden soll. Bei der Erwärmung von Brauchwasser befindet er sich in einem Brennraum eines Gehäuses, der von einem Mantel umgeben ist, in dem das zu erwärmende Wasser im Kreislauf geführt wird.In the context of the invention, the burner can also be used for heating smaller residential units, in which case it is to be used in suitable heating elements. When heating of process water it is in a combustion chamber of a housing, which is surrounded by a jacket, in which the water to be heated is circulated.

Weiterhin ist daran gedacht, ihn zum Vorwärmen des Kühlwassers von Motoren einzusetzen. Insbesondere hierzu wird eine Steuereinheit notwendig sein, welche die Vorwärmung zu einer bestimmten Zeit beginnen läßt, das Absperrorgan öffnet und die Zündanlage in Betrieb setzt.It is also planned to use it to preheat engine cooling water. In particular, a control unit will be required for this purpose, which allows preheating to start at a specific time, opens the shut-off element and starts the ignition system.

Further advantages, features and details emerge from the following description of a preferred exemplary embodiment and from the drawing; this shows in
Fig. 1

Fig. 2
is a schematic representation of the assignment of individual elements of the burner and the ignition system.

Ein erfindungsgemäßer Brenner 1 weist nach Fig. 1 eine Vorwärmschale 2 auf, in die ein haubenförmiger Brennstoff-und Flammenverteiler 3 eingesetzt ist. Dieser ist mit Öffnungen 4 versehen, welche den Brennstoff aus dem Innern des Verteilers 3 herausführen und kranzförmige Flammenringe erzeugen.According to FIG. 1, a burner 1 according to the invention has a preheating shell 2, into which a hood-shaped fuel and flame distributor 3 is inserted. This is provided with openings 4 which lead the fuel out of the interior of the distributor 3 and produce ring-shaped flame rings.

Der Brennstoff wird nach Fig. 2 beispielsweise aus einem unter Druck stehenden Tank 5 dessen Innendruck über ein Meßgerät 6 ablesbar ist, entnommen. Dies geschieht über eine Leitung 7, welche an den Brenner 1 angeschlossen wird. Hierfür ist das Anschlußstück 8 vorgesehen, welches die Leitung 7 in Zweigleitungen 9 und 10 aufteilt. Vor einem Absperrorgan 11 werden die Zweigleitungen 9 und 10 wieder vereinigt. Nach dem Absperrorgan 11 ist eine Düse 12 vorgesehen, über welche der Brennstoff durch eine nicht gezeigte Öffnung in der Vorwärmschale 2 in das Innere der Verteilerhaube 3 eindringen kann.2, for example, the fuel is taken from a pressurized tank 5 whose internal pressure can be read off via a measuring device 6. This is done via a line 7, which is connected to the burner 1. For this purpose, the connector 8 is provided, which divides the line 7 into branch lines 9 and 10. Before a shut-off device 11, the branch lines 9 and 10 are reunited. After the shut-off element 11, a nozzle 12 is provided, through which the fuel can penetrate into the interior of the distributor hood 3 through an opening (not shown) in the preheating shell 2.

Im wesentlichen sind die Zweigleitungen 9 und 10 unterhalb der Vorwärmschale 2 angeordnet und tragen diese. Einmal besteht jede Zweigleitung 9 und 10 aus einem aufsteigenden Ast 13, an den eine Heizstab 14 angelegt ist. Ein Querast 15, der entweder unterhalb der Vorwärmschale 2 oder innerhalb des Verteilers 3 angeordnet sein kann, verbindet den aufsteigenden Ast 13 mit einem absteigenden Ast 16, wobei sich die absteigenden Äste 13 der Zweigleitungen 9 und 10 mit jeweils einem querliegenden Düsenast 17 wieder vereinigen.Essentially, the branch lines 9 and 10 are arranged below the preheating shell 2 and carry it. Once each branch line 9 and 10 consists of an ascending branch 13, to which a heating element 14 is applied. A transverse branch 15, which can either be arranged below the preheating shell 2 or within the distributor 3, connects the ascending branch 13 to a descending branch 16, the descending branches 13 of the branch lines 9 and 10 reunite each with a transverse nozzle branch 17.

Von den Heizstäben 14 führen Anschlußleitungen 18 zu einer nicht näher gezeigten Energiequelle.Connection lines 18 lead from the heating rods 14 to an energy source, not shown in detail.

Das Absperrorgan kann beispielsweise ein Nadelventil sein, dessen Ventilspindel 19 in den einen Düsenast 17 eingesetzt ist. An der Verbindungsstelle zwischen Düsenast 17 und Ventilspindel 19 sind geeignete Spindelringe 20, Dichtungen und eine Stopfbüchse 21 vorgesehen. An der Ventilspindel befindet sich ein Bedienungsknopf 22.The shut-off device can be, for example, a needle valve, the valve spindle 19 of which is inserted into the one nozzle branch 17. Suitable spindle rings 20, seals and a stuffing box 21 are provided at the connection point between the nozzle branch 17 and the valve spindle 19. An operating button 22 is located on the valve spindle.

In einer verbesserten Ausführungsform wird von der Ventilspindel 19 auch eine, der Übersichtlichkeit halber nicht dargestellte Reinigungsnadel betätigt werden, welche beim Schließen des Absperrorgans 11 in die Düsenbohrung einfährt.In an improved embodiment, a cleaning needle, which is not shown for the sake of clarity, is also actuated by the valve spindle 19 and moves into the nozzle bore when the shut-off element 11 is closed.

Den Öffnungen 4 bzw. dem Verteiler 3 ist eine Zündanlage 23 zugeordnet, welche mit einer Energiequelle 24 gekoppelt ist. Diese Zündanlage 23 kann beispielsweise aus einer Zündkerze bestehen, wobei über ein entsprechendes elektrisches oder elektronisches Element -im Ausführungsbeispiel nicht gezeigt-periodisch ein Zündfunke erzeugt wird.An ignition system 23, which is coupled to an energy source 24, is assigned to the openings 4 or the distributor 3. This ignition system 23 can consist, for example, of a spark plug, an ignition spark being generated periodically via a corresponding electrical or electronic element — not shown in the exemplary embodiment.

Weitere elektrische oder elektronische Elemente zur Einschaltung der Zündanlage 23 in Abhängigkeit einer entsprechenden Temperatur des Heizstabes 14 oder einer vorbestimmten Zeit sind ebenfalls der Einfachheit halber vernachlässigt.Further electrical or electronic elements for switching on the ignition system 23 as a function of a corresponding temperature of the heating element 14 or a predetermined time are likewise neglected for the sake of simplicity.

Wird nun der Brenner 1 über die Leitung 7 an den Tank 5 angeschlossen und das Absperrorgan 11 geöffnet, so fließt Brennstoff, beispielsweise Öl, Dieselöl, Benzin od.dgl. bis zur Düse 12. Sobald Brennstoff aus der Düse 12 austritt, wird das Absperrorgan 11 geschlossen. Nunmehr werden die Heizstäbe 14 erwärmt und deren Wärme durch direkten Kontakt auf die aufsteigenden Äste 13 übertragen. Dies bewirkt, daß sich auch der Brennstoff in diesen Ästen 13 erwärmt und zumindest teilweise in einen gasförmigen Aggregatzustand übergeht. Dabei wird der flussige Brennstoff in entsprechendem Umfang in der Zweigleitung 9 und der Leitung 7 zurück in den Tank 5 gedrängt, so daß vor dem Absperrorgan 11 im wesentlichen nur gasförmiger Brennstoff ansteht.If the burner 1 is now connected to the tank 5 via the line 7 and the shut-off device 11 is opened, fuel, for example oil, diesel oil, gasoline or the like flows. to the nozzle 12. As soon as fuel emerges from the nozzle 12, the shut-off element 11 is closed. Now the heating rods 14 are heated and their heat by direct contact with the ascending branches 13 transferred. This has the effect that the fuel in these branches 13 also heats up and at least partially changes into a gaseous state. The liquid fuel is pushed to a corresponding extent in the branch line 9 and the line 7 back into the tank 5, so that essentially only gaseous fuel is present in front of the shut-off device 11.

Nach einer gewissen Zeit bzw. bei Erreichen einer bestimmten Temperatur wird das Absperrorgan 11 geöffnet und die Zündanlage 23 eingeschaltet. Aus der Düse 12 entweicht der gasförmige Brennstoff in den Verteiler 3 und durch dessen Öffnungen 4. Im Bereich der Zündanlage 23 bewirkt der Zündfunke ein Entzünden des leichter entflammbaren gasförmigen Brennstoffes. Dieser wärmt nun auch die Vorwärmschale 2 und den Verteiler 3 vor, so daß der nachfolgende flüssige Brennstoff durch die Düse versprüht ebenfalls entzündet wird und so die Tätigkeit des Brenners 1 aufrecht erhalten werden kann. Jetzt können Heizstäbe 14 und Zündanlage 23 abgeschaltet werden.After a certain time or when a certain temperature is reached, the shut-off device 11 is opened and the ignition system 23 is switched on. The gaseous fuel escapes from the nozzle 12 into the distributor 3 and through its openings 4. In the area of the ignition system 23, the ignition spark causes the more flammable gaseous fuel to ignite. This now also preheats the preheating shell 2 and the distributor 3, so that the subsequent liquid fuel sprayed through the nozzle is also ignited and so the activity of the burner 1 can be maintained. Now heating rods 14 and ignition system 23 can be switched off.
