Description

Diese Erfindung bezieht sich auf einen Ofen für feste, flüssige und gasförmige Brennstoffe mit einem von einer feuerfesten Ummantelung umgebenen Brennraum und einem Abzugsrohr für den Kaminabschluß und gegebenenfalls einem Rost.This invention relates to a furnace for solid, liquid and gaseous fuels with a combustion chamber surrounded by a refractory casing and an exhaust pipe for the chimney cap and optionally a grate.

Es ist bekannt, daß bei jedem thermischen Austausch durch Wände hindurch der beste Wirkungsgrad sich dann ergibt, wenn die zwei austauschenden Wärmeträger sich in Gegenströmung bewegen.It is known that with every thermal exchange through walls, the best efficiency results when the two exchanging heat carriers move in countercurrent.

Bei bekannten Heizöfen besteht der Nachteil, daß die Verbrennungsgase, wenn sie infolge der Abzugskraft des Rauchfanges den Verbrennungsraum verlassen, nur durch den höherliegenden Heizraum des Ofens durch den Kamin abziehen. Dabei streifen sie nur die höheren Wände des Ofens und die Heizplatte und über diese Wände geben sie Wärme an den Außenraum ab. Die Grenzen dieses Systems sind folgende.In known heating stoves there is the disadvantage that the combustion gases, when they leave the combustion chamber due to the pulling force of the chimney, are only drawn off through the chimney through the higher-lying heating chamber of the furnace. They only brush the higher walls of the stove and the heating plate and through these walls they give off heat to the outside. The limits of this system are as follows.

Größe des Ofens, Oberfläche für den thermischen Austausch. Nachteile: die Verbrennungsgase bewegen sich zur Umgebungsluft nicht in Gegenströmung und deshalb ist der Wirkungsgrad beim thermischen Austausch durch die Wände des Ofens sehr niedrig.Size of the furnace, surface for thermal exchange. Disadvantages: the combustion gases do not move in counterflow to the ambient air and therefore the efficiency in thermal exchange through the walls of the furnace is very low.

Die zur Verbrennung notwendige Luft wird im untersten Raum eingesaugt, d.h. im kältesten.The air required for combustion is sucked into the lowest room, i.e. in the coldest.

Der beschränkte Wärmewiderstand, welchem die Gase bei ihrem Durchzug ausgesetzt sind, bewirkt, daß diese mit einem sehr hohen Wärmegehalt in den Kamin einziehen und somit diese Wärme verloren geht.The limited thermal resistance to which the gases are exposed during their passage means that they move into the chimney with a very high heat content and thus this heat is lost.

Die einzige Methode, mit der man meistens diesem Nachteil zumindest teilweise.vorbeugt, ist, zwischen dem Verbrennungsraum und dem Kamin eine schlangenartige Röhre anzubringen, in der beispielsweise Wasser zirkuliert.The only way to prevent this disadvantage, at least in part, is to place a snake-like tube between the combustion chamber and the chimney, in which water circulates, for example.

Aufgabe der Erfindung ist es, einen Ofen zu schaffen, der eine bessere Ausnutzung der Wärme der Rauchgase als bekannte öfen ermöglicht.The object of the invention is to provide an oven which enables better utilization of the heat of the flue gases than known ovens.

Dies wird erfindungsgemäß dadurch erreicht, daß das Abzugsrohr beim Boden des Ofens, unterhalb der Feuerstelle, in diesen mündet, und daß außerhalb der feuerfesten Ummantelung, an vorzugsweise drei Seiten des Ofens, vertikale Kanäle für die Rauchgase vorgesehen sind, die obere Einlässe und untere, in etwa auf der Höhe der Abzugsrohrmündung oder darunter befindliche Auslässe aufweisen.This is achieved according to the invention in that the exhaust pipe opens into the bottom of the furnace, below the fireplace, and in that outside the refractory casing, preferably on three sides of the furnace, vertical ducts for the flue gases are provided, the upper inlets and the lower, have approximately at the level of the outlet pipe mouth or outlets located below.

Mit der Erfindung erreicht man die höchste Ausnützung der.Verbrennungsgase (Herabsetzung ihrer eigenen Temperatur auf ein Mindestmaß) und eine große Ofen-Oberfläche für den thermischen Austauscher.The invention achieves the highest utilization of the combustion gases (reducing their own temperature to a minimum) and a large furnace surface for the thermal exchanger.

Ein vorteilhaftes Ausführungsbeispiel sieht eine den Ofen mit den Kanälen seitlich umgebende Verkleidung vor, die oben und unten offen ist.An advantageous exemplary embodiment provides a cladding which laterally surrounds the furnace with the channels and is open at the top and bottom.

Durch diese Verkleidung werden Gegenkanäle gebildet, durch die Umgebungsluft von unten nach oben geführt wird. Da die Verbrennungsgase in Gegenströmung von oben nach unten strömen, ergibt sich ein hoher Wirkungsgrad für den Wärmeaustausch.Through this cladding counter channels are formed through which ambient air is led from the bottom up. Since the combustion gases flow in counterflow from top to bottom, there is a high efficiency for the heat exchange.

Erfindungsgemäß erzielt man weiters eine Verbesserung der Verbrennung durch eine Speisung des Ofens mit vorgeheizter Luft.According to the invention, combustion is further improved by supplying the furnace with preheated air.

Vorteilhaft ist vorgesehen, daß im oberen Bereich des Brennraumes, vorzugsweise in der Höhe der Einlässe der Kanäle;eine durch eine Klappe oder dgl. abschließbare, in das Abzugsrohr für den Kaminanschluß führende Öffnung vorgesehen ist.It is advantageously provided that in the upper area of the combustion chamber, preferably at the level of the inlets of the channels, there is an opening which can be closed by a flap or the like and leads into the exhaust pipe for the chimney connection.

Die Klappe wird nur zum Anheiz.en des Ofens geöffnet und bleibt während des Betriebes geschlossen.The flap is only opened to heat the furnace and remains closed during operation.

Ein Ausführungsbeispiel der Erfindung sieht eine zwischen der Feuerstelle einerseits und der Mündung des Abzugsrohres und den Auslässen der Kanäle andererseits befindliche Trennplatte vor.An embodiment of the invention provides a partition plate located between the fireplace on the one hand and the mouth of the exhaust pipe and the outlets of the channels on the other.

Vorteilhaft ist die Trennplatte das Kesselblech der Aschenablage.The separating plate is advantageously the boiler plate of the ash tray.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Figur der Zeichnung beschrieben.An embodiment of the invention is described below with reference to the figure of the drawing.

Die Figur der Zeichnung zeigt ein Schaubild, teilweise im Schnitt, eines erfindungsgemäßen Ofens.The figure of the drawing shows a diagram, partly in section, of an oven according to the invention.

Aus der Figur der Zeichnung ist deutlich die gegenläufige Richtung des Stromes der Verbrennungsgase und der zu erwärmenden Raumluft ersichtlich.From the figure of the drawing, the opposite direction of the flow of the combustion gases and the room air to be heated can be clearly seen.

Der innere Teil des Ofens entspricht praktisch herkömmlichen Öfen traditioneller Art. Er weist eine öffnung 1 für den Lufteintritt in den Verbrennungsraum für die Aschenherausnahme auf. Ein Kesselblech 2 für die Aschenablage, eine Öffnung 4 zum Anheizen des Ofens, eine Öffnung 5 für die Zugabe von Brennmaterial, einen Rost 6 und eine feuerfeste Verkleidung 7, welche die gesamte innere Ofenoberflächenbekleidung bildet, wobei im Ausführungsbeispiel eine Heizplatte 15 von dieser Verkleidung ausgenommen ist.The inner part of the furnace corresponds practically to conventional stoves of traditional type. It has an opening 1 for the air to enter the combustion chamber for the ash removal. A boiler plate 2 for the ash tray, an opening 4 for heating the furnace, an opening 5 for the addition of fuel, a grate 6 and a fireproof cladding 7, which forms the entire inner furnace surface cladding, a heating plate 15 being excluded from this cladding in the exemplary embodiment is.

Außen an der feuerfesten Verkleidung 7 sind die erfindungsgemäßen Kanäle 9 für die Ableitung bzw. Umleitung der Rauchgase angeordnet.The channels 9 according to the invention for discharging or diverting the flue gases are arranged on the outside of the refractory lining 7.

Im Ausführungsbeispiel sind die Kanäle 9 an drei-Wänden des Ofens angeordnet. Bei der oberen Öffnung 22, die zum Abzugsrohr 8 führt, gibt es eine Klappe 13, mittels der diese Öffnung 22 verschließbar ist,und zwar über einen Riegel 10. Das Abzugsrohr 8 ist bis zum Ofenboden hinabgeführt und weist dort eine Mündung 11 in den Ofen auf, die sich unterhalb des Kesselbleches 2 befindet.In the exemplary embodiment, the channels 9 are arranged on three walls of the furnace. At the upper opening 22, which for Exhaust pipe 8 leads, there is a flap 13, by means of which this opening 22 can be closed, namely via a bolt 10. The exhaust pipe 8 is led down to the furnace floor and there has a mouth 11 in the furnace, which is below the boiler plate 2 located.

Die Kanäle 9 weisen obere Einlässe 23 und untere Auslässe 24 auf.The channels 9 have upper inlets 23 and lower outlets 24.

Der Ofen ist weiters von einer Ummantelung 12 umgeben, die unten und oben offen ist und die zusammen mit der Ofenwand und den Kanälen 9 Gegenkanäle 25 bildet, durch die die Umgebungsluft in Strömen 20, 21 von unten nach oben dem Ofen entlang geführt wird und die in diesen Gegenkanälen 25 im Gegenstrom zu den Rauchgasen: geführt ist.The furnace is also surrounded by a casing 12 which is open at the top and bottom and which, together with the furnace wall and the channels 9, forms counter-channels 25 through which the ambient air is conducted in streams 20, 21 from bottom to top of the furnace and which in these counter-channels 25 in counterflow to the flue gases: is guided.

Die Arbeitsweise des erfindungsgemäßen Ofens ist folgende: Zum Anheizen des Ofens wird die Klappe 13 mittels des Riegels 10 geöffnet, so daß die öffnung 22, die direkt ins Abzugsrohr 8 führt, offen ist und eventuell das Abzugsrohr 8 nach unten geschlossen ist.The method of operation of the furnace according to the invention is as follows: To heat the furnace, the flap 13 is opened by means of the latch 10, so that the opening 22 which leads directly into the exhaust pipe 8 is open and the exhaust pipe 8 is possibly closed at the bottom.

In diesem Zustand entspricht der erfindungsgemäße Ofen jedem herkömmlichen Ofen, d.h. der Verbrennungsraum ist direkt mit dem Kamin verbunden. Durch diesen Umstand wird-das Anheizen des Ofens erleichtert.In this state, the furnace according to the invention corresponds to any conventional furnace, i.e. the combustion chamber is directly connected to the fireplace. This makes heating the oven easier.

Nach dem Anheizen des Ofens schließt man die Öffnung 22 mit der Klappe 13 und die eventuell zuvor geschlossene Mündung 11 des Abzugsrohres 8 wird geöffnet.After heating up the furnace, the opening 22 is closed with the flap 13 and the possibly previously closed mouth 11 of the exhaust pipe 8 is opened.

Dadurch sind die Voraussetzungen für die erfindungsgemäße Funktion des Ofens gegeben. Die warmen Verbrennungsgase steigen, wie mit den Pfeilen 14 gezeigt, nach oben und geben sofort einen Teil ihrer Wärme durch die Heizplatte 15 ab, wie es mit dem Pfeil 16 angezeigt ist. Anschließend jedoch sind die Rauchgase gezwungen, durch die Kanäle 9 nach abwärts bis zum Ofenboden zu sinken, wie dies vom Pfeil 17 angezeigt ist. Dies erfolgt selbstverständlich durch den Zug des Kamines.This provides the prerequisites for the functioning of the furnace according to the invention. The warm combustion gases rise, as shown by the arrows 14, and immediately give off part of their heat through the heating plate 15, as indicated by the arrow 16. Subsequently, however, the flue gases are forced downwards through channels 9 to sink to the bottom of the furnace, as indicated by arrow 17. Of course, this is done by pulling the fireplace.

Vom Ofenboden, der praktisch ein Sammelbecken, welches die Kanäle 9 verbindet, bildet, gelangen die Rauchgase, wie der Pfeil 18 zeigt, in die Mündung 11 des Abzugsrohres 8.From the furnace floor, which practically forms a collecting basin, which connects the channels 9, the flue gases, as the arrow 18 shows, enter the mouth 11 of the exhaust pipe 8.

Im Gegensatz zu den Rauchgasen strömt die Raumluft durch das Gitter der Ummantelung 12, wie durch die Pfeile 21 angezeigt, heraus, nachdem sie, wie der Pfeil 20 zeigt, beim Ofenboden in die Kanäle 25 eingezogen ist, die sie, sich erwärmend, nach oben durchströmt. Gleichzeitig fließt Luft in den Verbrennungsraum durch die öffnung 1 und diese ist gezwungen, das Sammelbecken zu durchqueren und sich vorzuwärmen, wodurch eine Verbesserung der Verbrennung erreicht wird.In contrast to the flue gases, the room air flows out through the grille of the casing 12, as indicated by the arrows 21, after, as the arrow 20 shows, it is drawn into the ducts 25 at the bottom of the furnace, which, as it heats upward flows through. At the same time, air flows into the combustion chamber through the opening 1 and this is forced to cross the collecting basin and preheat, which improves the combustion.

Eine besonders gute Einstellung des Ofens in bezug auf die verbrennende Brennstoffart ergibt sich durch ein angepaßtes teilweises öffnen der Klappe 13.A particularly good setting of the furnace in relation to the type of fuel burning results from an adapted partial opening of the flap 13.
