Abstract

A heat-recovery system for flue gases is described, the flue gases passing through a pipe coil from the combustion region of the furnace into a chimney and the pipe coil being composed of pipe pieces (1) of approximately rectangular cross-section and forming a sitting or lying system. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Ausnützung der Abwärme von Rauchgasen, in Form einer seitlich von einem Ofen durch einen Wohnraum verlaufenden Rohrschlange, durch welche die Rauchgase vom Verbrennungsbereich des Ofens in einen Kamin gelangen.The invention relates to a device for utilizing the waste heat of flue gases, in the form of a pipe coil running laterally from an oven through a living space, through which the flue gases pass from the combustion area of the oven into a chimney.

In der AT-PS 359 695 ist eine derartige Einrichtung beschrieben, bei welcher in übereinander liegenden Kanälen Rohrbündel angeordnet sind, durch welche das Rauchgas fließt. Aus solchen Rohrbündeln lassen sich nur schwierig Rohrschlangen herstellen, welche ein vorgegebenes Volumen ohne Zwischenraum ausfüllen. Der in der AT-PS 359 695 beschriebene "Beistellkasten", welcher die Rohrbündel enthält, ist kaum belastbar und dient daher, abgesehen von der Wärmeabgabe, keiner Funktion.Such a device is described in AT-PS 359 695, in which tube bundles are arranged in channels one above the other, through which the flue gas flows. It is difficult to produce coils from such tube bundles, which fill a given volume without any space. The "side box" described in AT-PS 359 695, which contains the tube bundle, is hardly resilient and therefore, apart from the heat emission, serves no function.

Aus der AT-PS 343 317 ist an sich bereits der Vorschlag bekannt, vom Rauchgas eines Kachelofens durchflossene Hohlräume mit Wänden zu umgeben, die eine Sitzbank oder Liege bilden. Diese Wände müssen jedoch in aufwendiger Weise aus Schamottsteinen bzw. Sandsteinplatten aufgebaut werden.From AT-PS 343 317 the proposal is known per se to surround cavities through which the flue gas of a tiled stove flows, with walls which form a bench or couch. However, these walls have to be constructed in a complex manner from refractory bricks or sandstone slabs.

Die Erfindung geht von der Aufgabe aus, eine Einrichtung der eingangs skizzierten Art aus vorgefertigten Elementen aufzubauen, welche sich einfach zu einer Rohrschlange zusammensetzen lassen, welche eine zweckmäßige Form aufweist und den bei Liege- oder Sitzeinrichtungen auftretenden Belastungen unterworfen werden kann.The invention is based on the object of constructing a device of the type outlined at the outset from prefabricated elements which can be easily assembled into a pipe coil which has an expedient shape and can be subjected to the loads which occur in lying or seating devices.

Erfindungsgemäß ist zur Lösung dieser Aufgabe vorgesehen, daß die Rohrschlange aus im Querschnitt etwa rechteckförmigen Rohrstücken zusammengesetzt ist und wenigstens einen Teil einer in an sich bekannter Weise von Rauchgas durchströmten Sitz- oder Liegeeinrichtung bildet.According to the invention it is provided to solve this problem that the pipe coil is composed of pipe sections which are approximately rectangular in cross section and at least part of a flue gas in a manner known per se flows through sitting or lying device.

Soweit derartige Rohrstücke bisher im Ofenbau verwendet worden sind (vgl. AT-PS 373 374), ging es darum, den Ofen selbst aus diesen Rohrstücken zusammenzusetzen. Dies geschah durch Übereinanderlegen horizontal verlaufender Ringe, was insgesamt in einer Quaderform mit lotrechtem Innenschacht resultiert. Die kompakte Form von Sitz- oder Liegeeinrichtungen wird hier nicht nahegelegt.As far as such pieces of pipe have been used in furnace construction (see AT-PS 373 374), it was a matter of assembling the furnace itself from these pieces of pipe. This was done by superimposing horizontally running rings, which overall resulted in a cuboid shape with a vertical inner shaft. The compact form of seating or lying arrangements is not suggested here.

Die erfindungsgemäße Maßnahme gibt dem Architekten große Freiheit bei der Gestaltung von wärmeabgebenden Wohnlandschaften. Dies gilt insbesondere dann, wenn auch Rohrstücke vorgesehen werden, welche in der horizontalen Ebene gekrümmt sind. Bei der Gestaltung des Grundrisses besteht dann erhebliche Freiheit, wogegen der rechteckige Querschnitt der Rohre die sichere Verbindung derselben aneinander gewährleistet. Daß die entstehenden Raumformen vertikale Wände und horizontale Auflageflächen aufweisen, bedeutet für die Praxis keine Einschränkung.The measure according to the invention gives the architect great freedom in the design of heat-emitting residential landscapes. This applies in particular if pipe pieces are also provided which are curved in the horizontal plane. There is then considerable freedom in the design of the floor plan, whereas the rectangular cross section of the pipes ensures that they are securely connected to one another. In practice, the fact that the resulting spatial forms have vertical walls and horizontal contact surfaces means no restrictions.

Einfache Beispiele für die Anwendung der Erfindung werden anschließend anhand der Zeichnung erläutert.Simple examples for the application of the invention are explained below with reference to the drawing.

Fig. 1 ist die schaubildliche Darstellung eines ersten Ausführungsbeispieles, das unter Verwendung gerader Rohrstücke aufgebaut ist, Fig. 2 ist die schaubildliche Darstellung eines zweiten Ausführungsbeispieles, bei dem auch gekrümmte Rohrstücke Verwendung finden.1 is a diagrammatic representation of a first exemplary embodiment, which is constructed using straight pipe pieces, FIG. 2 is a diagrammatic representation of a second exemplary embodiment, in which curved pipe pieces are also used.

Bei der erfindungsgemäßen Einrichtung werden die aus dem Verbrennungsraum eines Kachelofens 2 austretenden Rauchgase nicht unmittelbar oder lediglich durch oberhalb der Verbrennungseinrichtung angeordnete Rauchzüge zum Kamin 3 geleitet. Vielmehr strömen die Rauchgase, wie in der Zeichnung durch Pfeile angedeutet ist, durch eine Rohrschlange 4, welche seitlich vom Ofen durch den Wohnraum verläuft.In the device according to the invention, the flue gases emerging from the combustion chamber of a tiled stove 2 are not passed to the chimney 3 directly or only through smoke flues arranged above the combustion device headed. Rather, the flue gases, as indicated in the drawing by arrows, flow through a pipe coil 4, which runs laterally from the stove through the living room.

Um die Rohrschlange 4 hinreichend kompakt und statisch belastbar zu machen, ist diese aus Rohrstücken 1 zusammengesetzt, welche rechteckigen Querschnitt aufweisen. Die Rohrstücke 1 können sowohl mit ihren offenen Rändern zusammengesetzt als auch seitlich aneinander gelegt werden. Der Übergang des Rauchgases zwischen zwei unmittelbar aneinander liegenden Rohrstücken erfolgt dabei derart, daß die Stirnseiten der Rohrstücke 1 durch Platten 5 verschlossen und die aneinander liegenden Seitenwände der Rohrstücke mit einer Durchbrechung 6 versehen werden.In order to make the pipe coil 4 sufficiently compact and statically resilient, it is composed of pipe pieces 1 which have a rectangular cross section. The pipe sections 1 can be put together with their open edges or placed side by side. The transition of the flue gas between two directly adjacent pipe sections takes place in such a way that the end faces of the pipe sections 1 are closed by plates 5 and the side walls of the pipe sections lying against one another are provided with an opening 6.

Mit derartigen Rohrstücken 1 als Bauelement lassen sich Wohnlandschaften fast beliebiger Form herstellen, besonders wenn einzelne Rohrstücke 1, so wie in Fig. 2 dargestellt, in der Horizontalebene gekrümmt sind. Die erreichbare Formenvielfalt erhöht sich weiterhin, wenn auch im Querschnitt rechteckige Rohrstücke verwendet werden, welche ein Rohrknie bilden. Wann solche Elemente zur Verfügung stehen, kann auch der Kachelofen 2 selbst in aus AT-PS 373 374 bekannter Weise aus Rohrstücken zusammen gesetzt werden, die, abgesehen von den seitlichen Durchbrüchen, in Richtung ihrer Achse durchströmt werden, wobei die Ecken der über den Brennraum verlaufenden Feuerzüge durch je ein Rohrknie gebildet sind.With such pipe sections 1 as a component, living landscapes of almost any shape can be produced, especially if individual pipe sections 1, as shown in FIG. 2, are curved in the horizontal plane. The variety of shapes that can be achieved increases further if rectangular pipe sections are used in cross-section, which form a pipe bend. When such elements are available, the tiled stove 2 itself can be assembled in a manner known from AT-PS 373 374 from pipe sections which, apart from the lateral openings, are flowed through in the direction of their axis, the corners of which are above the combustion chamber running fire trains are each formed by a pipe elbow.
