Description

Feuerstätte fireplace

Die Erfindung betrifft eine Feuerstätte mit einem über eine Befüllöffnung mit Brennmaterial befüllbaren Füllraum und einem mit diesem über eine Nachschuböffnung verbundenen Brennraum, wobei in den Füllraum PrimMuft _ufuhröffhungen münden, welche gegenüber der Nachschuböffnung nach oben höhenversetzt angeordnet sind.The invention relates to a fireplace with a filling space that can be filled with fuel via a filling opening and a combustion space connected to the filling space via a supply opening, supply openings opening into the filling space PrimMuft, which are arranged offset in height from the supply opening.

Gepreßtes Brennmaterial kann aus verschiedenartigen Grundstoffen, wie Holz, Karton, Papier o.a. bestehen. So sind Holzpellets beispielsweise aus naturbelassenem Holz, das aus in der holzverarbeitenden Industrie anfallenden Hobel- und Sägespänen erzeugt wird. Ohne Zugabe von Bindemitteln wird der unbehandelte Rohstoff unter hohem Druck verdichtet und pelletiert. Die entstehenden zylindrischen Röllchen haben geringe Restfeuchte und einen hohen Brennwert. Diese positiven Materialeigenschaften lassen sich aber mit herkömmlichen eingangs genannten Feuerstätten nur sehr schwer nutzen, da aufgrund der geringen Größe der Preßlinge die Zufuhr von Sauerstoff zu der Stelle, an der die Verbrennung stattfindet, behindert wird. Die Folge ist eine mit schlechten Abgaswerten verbundene Verbrennung innerhalb der Feuerstätte.Compressed fuel can be made from various raw materials, such as wood, cardboard, paper or the like. consist. For example, wood pellets are made from natural wood, which is produced from wood shavings and sawdust. Without the addition of binders, the untreated raw material is compressed and pelletized under high pressure. The resulting cylindrical rolls have low residual moisture and a high calorific value. However, these positive material properties are very difficult to use with conventional fireplaces mentioned at the outset, since the supply of oxygen to the point at which the combustion takes place is impeded due to the small size of the compacts. The result is a combustion within the fireplace associated with poor exhaust gas values.

Aufgabe der Erfindung ist es daher, eine Feuerstätte der eingangs genannten Art anzugeben, mit der eine gut kontrollierbare Verbrennung, insbesondere von gepreßtem Brennmaterial vorgenommen werden kann und welche die Erzielung sehr niedriger Abgaswerte bei der Verbrennung ermöglicht.It is therefore an object of the invention to provide a fireplace of the type mentioned at the outset with which combustion can be controlled well, in particular of compressed fuel, and which enables very low exhaust gas values to be achieved during combustion.

Erfindungsgemäß wird dies dadurch erreicht, daß der Füllraum ein Fördermittel umfaßt, über welches das Brennmaterial von der Befüllöffnung in den Brennraum forderbar ist, und daß zumindest ein Teil der PrimMuftzuftihröffhungen derart in den Füllraum mündet, daß der zugeführte Teilstrom der Primärluft durch das Brennmaterial hindurch in den Brennraum gelangt.According to the invention, this is achieved in that the filling chamber comprises a means of conveyance via which the fuel can be conveyed from the filling opening into the combustion chamber, and in that at least some of the primary air supply openings open into the filling chamber in such a way that the partial flow of primary air supplied flows through the fuel reaches the combustion chamber.

Auf diese Weise gelangt das Brennmaterial über das Fördermittel in den Brennraum, wobei zugleich die von oben nach unten strömende Primärluft durch das Brennmaterial hindurch zum oberen Teil des im Brennraum befindlichen Glutnestes gelangen kann und dadurch für eine vollständige Verbrennung sorgt, wobei immer soviel Luft angesaugt wird, wie für die Verbrennung benötigt wird. In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß das Fördermittel durch eine Rutschwand gebildet ist, die sich - in Gebrauchslage gesehen - von der unteren Berandung der Befüllöffhung in den Bereich der Nachschuböffnung schräg nach unten erstreckt und auf deren Oberseite das Brennmaterial von der Befüllöffhung zur Nachschuböffnung und in den Brennraum zu einer dort angeordneten Auffangvorrichtung bewegbar ist.In this way, the fuel reaches the combustion chamber via the conveyor, whereby the primary air flowing downwards through the fuel can reach the upper part of the glow nest in the combustion chamber and thereby ensures complete combustion, with always as much air being sucked in as needed for combustion. In a further embodiment of the invention it can be provided that the funding is formed by a sliding wall, which - seen in the position of use - extends obliquely downwards from the lower edge of the filling opening into the area of the supply opening and on the top thereof the fuel from the filling opening to Replenishment opening and into the combustion chamber to a collecting device arranged there is movable.

Das auf diese Weise gebildete Fördermittel ermöglicht die Förderung des Brennmaterials allein über die Schwerkraft und benötigt daher keine Fremdenergie für ihren Betrieb. Alternativ zum Rutschbrett kann auch ein Rohr oder eine gewölbte Fläche als Fördermittel dienen.The funding created in this way enables the fuel to be conveyed solely by gravity and therefore does not require any external energy for its operation. As an alternative to the slide board, a pipe or a curved surface can also be used as funding.

Gemäß einer Weiterbildung der Erfindung kann vorgesehen sein, daß die Prim uftzufuhröffhungen derart angeordnet sind, daß die in den Füllraum strömende Primärluft sowohl unterhalb als auch oberhalb der Rutschwand zur Nachschuböffnung und über diese in den Brennraum gelangt.According to a development of the invention, it can be provided that the primary air supply openings are arranged in such a way that the primary air flowing into the filling chamber reaches the supply opening both below and above the sliding wall and via this into the combustion chamber.

Mit Hilfe der Rutschwand wird der Füllraum in einen oberen und einen unteren Teil unterteilt, sodaß die Primärluft über beide Raumteile zur Nachschuböff ung geleitet wird, nur die Oberseite der Rutschwand aber mit Brennmaterial belegt ist, sodaß die an der Unterseite strömende Primärluft ohne Behinderung in den Brennraum übertreten kann. Der dadurch erreichbare hohe Primärluftdurchsatz fordert die Verfeuerung des im Brennraum befindlichen Brennmaterials, durch die Trennung von Brennraum und Fülhaum wird aber immer nur der in die Auffangvorrichtung gelangende Teil des Brennmaterials verbrannt und eine sofortige Verbrennung des gesamten im Fülhaum befindlichen Vorratsmaterials verhindert.With the help of the slide wall, the filling chamber is divided into an upper and a lower part, so that the primary air is led to the replenishment opening via both room parts, but only the top of the slide wall is filled with fuel, so that the primary air flowing on the underside flows into the Combustion chamber can cross. The high primary air flow rate that can be achieved in this way requires the combustion of the fuel in the combustion chamber, but the separation of the combustion chamber and the filling chamber means that only the part of the fuel material that gets into the collecting device is burned and an immediate combustion of the entire supply material located in the filling chamber is prevented.

In weiterer Ausbildung der Erfindung können in den Brennraum mündende Sel mdMufti ifiihröffiiungen vorgesehen sein, welche die Nachverbrennung von bei der Verbrennung entstehenden Gasen fördert.In a further embodiment of the invention, Sel mdMufti ifiihröffii openings opening into the combustion chamber can be provided, which promotes the post-combustion of gases produced during the combustion.

Um eine in Form eines Baukastensystems zusammensetzbare Feuerstätte zu schaffen, kann vorgesehen sein, daß der Brennraum und der Fülhaum durch eine gewölbte Trennwand voneinander getrennt sind, die an ihrem unteren Ende unter Ausbildung der Nachschuböffhung von einer konkav gekrümmten Bodenfläche beabstandet ist. Durch die besondere Formgebung der Trennwand kann die Saugzugwirkung, mit der die Primärluft durch die Feuerstätte gesaugt wird, verbessert werden. In weiterer Ausbildung der Erfindung kann der Brennraum sich nach oben hin zu einer schlitzförmigen Auslaßöffnung verjüngen, über die der Brennraum mit einem die Verbrennungsabgase ableitenden Kanal verbunden ist. Die durch die schlitz- oder düsenförmige Auslaßöffhung und die höhenversetzte Anordnung von Nachschuböffhung und Füllöffnung erreichbare Syphonwirkung ermöglicht eine Verbrennung mit sehr geringen Abgaswerten.In order to create a fireplace which can be assembled in the form of a modular system, it can be provided that the combustion chamber and the filling chamber are separated from one another by a curved partition wall which is spaced at its lower end from a concavely curved floor surface while forming the replenishment opening. Due to the special shape of the partition, the suction draft with which the primary air is drawn through the fireplace can be improved. In a further embodiment of the invention, the combustion chamber can taper towards the top to a slot-shaped outlet opening, via which the combustion chamber is connected to a channel that discharges the combustion exhaust gases. The siphon effect that can be achieved through the slot-shaped or nozzle-shaped outlet opening and the height-offset arrangement of replenishment opening and filling opening enables combustion with very low exhaust gas values.

Um eine Zufuhr von Primärluft oberhalb und unterhalb der Rutschwand zu erreichen, kann in weiterer Ausbildung der Erfindung vorgesehen sein, daß in der Füllraumwandung ein Kanal für die Zufuhr von Primärluft vorgesehen ist, der an seinem Auslaßende mit einem im oberen Bereich der Rutschwand angeordneten Luftverteilungskörper verbunden ist, über welchen die Primärluft auf die in den oberhalb der Rutschwand befindlichen Teil des Brennraumes mündenden Luft_ ιführöffnungen und die in den unterhalb der Rutschwand befindlichen Teil des Brennraumes mündenden Luftzuführöffnungen verteilt wird.In order to achieve a supply of primary air above and below the slide wall, it can be provided in a further embodiment of the invention that a channel for the supply of primary air is provided in the filling chamber wall, which channel is connected at its outlet end to an air distribution body arranged in the upper region of the slide wall is, via which the primary air is distributed to the air-discharge openings opening into the part of the combustion chamber located above the sliding wall and the air supply openings opening into the part of the combustion chamber located below the sliding wall.

Eine sehr gleichmäßige Verteilung der Primärluft kann in Weiterbildung der Erfindung dadurch erreicht werden, daß der Luftverteilungskörper aus einem Lochblech gebildet ist, welcher eine Auflagefläche für den oberen Teil der Rutschwand bildet.A very uniform distribution of the primary air can be achieved in a further development of the invention in that the air distribution body is formed from a perforated plate, which forms a contact surface for the upper part of the sliding wall.

Gemäß einer weiteren Ausfülrrungsform der Erfindung kann die Auffangvorrichtung für das Brennmaterial aus einem von der Bodenfläche des Brennraumes beabstandeten Brennerrost mit einer vorzugsweise im Querschnitt V-förmigen Vertiefung gebildet sein. Die V-förmige Vertiefung verhindert ein übermäßig starkes Nachrutschen des Brennmaterials in den Brennerrost.According to a further embodiment of the invention, the collecting device for the fuel can be formed from a burner grate spaced apart from the bottom surface of the combustion chamber and having a recess which is preferably V-shaped in cross section. The V-shaped recess prevents the fuel from sliding excessively into the burner grate.

Gemäß einer weiteren Ausführungsform der Erfindung kann der Brennerrost aus einem Lochblech geformt sein und es kann die V-förmige Vertiefung des Brennerrostes an ihren Enden durch schräge, aus Lochblech gebildete Abschlußwände begrenzt sein. Diese verhindern ein seitliches Hinausgleiten des Brennmaterials aus dem Brennerrost.According to a further embodiment of the invention, the burner grate can be formed from a perforated plate and the V-shaped recess of the burner grate can be delimited at its ends by oblique end walls formed from perforated plate. These prevent the fuel from sliding sideways out of the burner grate.

In weiterer Ausbildung der Erfindung kann der Brennerrost einen Teil eines zweiteiligen Einsatzes bilden, dessen zweiter Teil einen Distanzhalter und einen Handgriff umfaßt, die lösbar miteinander verbindbar sind. Die zweiteilige Form des Einsatzes gestattet eine vereinfachte Herstellung desselben.In a further embodiment of the invention, the burner grate can form part of a two-part insert, the second part of which comprises a spacer and a handle, which can be detachably connected to one another. The two-part form of the insert allows a simplified manufacture of the same.

Schließlich kann vorgesehen sein, daß der Distanzhalter an seiner Oberseite eine querverlaufende, winkelförmige Leiste aufweist, die eine Auflagefläche für den unteren Teil der Rutschwand bildet. Bei aufgesetzter Rutschwand wird die Lage des Distanzhalters und des mit diesem lösbar verbundenen Brennerrostes innerhalb der Feuerstätte stabilisiert.Finally, it can be provided that the spacer has a transverse, angular bar on its top, which has a bearing surface for the lower Forms part of the slide wall. When the slide wall is attached, the position of the spacer and the burner grate releasably connected to it are stabilized within the fireplace.

Die Erfindung wird nachfolgend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele eingehend erläutert. Es zeigt dabeiThe invention is explained in detail below using the exemplary embodiments illustrated in the drawings. It shows

Fig.l zeigt eine in einem Kachelofen ausgebildete Feuerstätte, insbesondere für die Verfeuerung von gepreßtem Brennmaterial 9, z.B. für Pellets, das aus verschiedenen Rohstoffen, z.B. Holz, Karton, Papier od. dgl. bestehen kann. An sich kann diese Feuerstätte aber auch z.B. in einem Herd oder in einer anderen Art von Verbrennungseinrichtung eingebaut sein.Fig.l shows a fireplace designed in a tiled stove, in particular for the combustion of pressed fuel 9, e.g. for pellets made from various raw materials, e.g. Wood, cardboard, paper or the like. Can exist. In itself, this fireplace can also e.g. built into a stove or other type of combustion device.

Über eine Befüllöffnung 6, die über eine Ofentüre 5 verschließbar ist, gelangt das gepreßte Brennmaterial 9 in einen Fülhaum 11, der durch eine gewölbte Trennwand 3 aus Schamott von einem Brennraum 12 getrennt ist. Der Vorteil, der bei der Verwendung von Pellets als Brennmaterial erzielbar ist, liegt in der sauberen und sehr bequemen Handhabung, es können die Pellets beispielsweise auch über eine Saugeinrichtung oder ein in die Befüllöffnung reichendes Förderband 50 automatisch in den Fülhaum 11 eingebracht werden (Fig.6).Via a filling opening 6, which can be closed via an oven door 5, the pressed fuel 9 enters a filling chamber 11, which is separated from a combustion chamber 12 by a curved partition 3 made of fireclay. The advantage that can be achieved when using pellets as fuel is that they are clean and very convenient to use; the pellets can also be automatically introduced into the filling chamber 11, for example via a suction device or a conveyor belt 50 reaching into the filling opening (FIG. 6).

Am unteren Ende der Trennwand 3 ist eine Nachschuböffnung 10 durch Beabstandung der Trennwand 3 von einer konkav gebrummte Bodenfläche 18 ausgebildet. Durch die Nachschuböffhung 10 gelangt das Brennmaterial 9 in den Brennraum 12 und wird dort verfeuert.At the lower end of the partition 3, a replenishment opening 10 is formed by spacing the partition 3 from a concave bottom surface 18. The fuel 9 enters the combustion chamber 12 through the replenishment opening 10 and is burned there.

Um eine möglichst vollständige Verbrennung zu gewährleisten, verjüngt sich der Brennraum 12 nach oben hin zu einer schlitzförmigen Auslaßöffhung 27, über die dieser mit einem die Verbrennungsabgase ableitenden Kanal verbunden ist, der in Fig.l nicht dargestellt ist. Diese schlitzförmige Auslaßöffnung 27 entsteht durch ein Schamott-Teil 1 mit seitlichen Distanzstützen 2, die auf der gewölbten Trennwand 3 ruhen. Da die Befüllöffnung 6 gegenüber der Nachschuböffhung 10 nach oben höhenversetzt ist, ergibt sich eine Syphonwirkung, aufgrund der die über einen im Bereich der Befüllöffhung 6 in den Fülhaum 11 mündenden Primärluftkanal 14 kommende Primärluft nur in dem Ausmaß angesaugt wird, in dem sie im Brennraum 12 zur Verbrennung benötigt wird. Die Nachschuböffhung 10 ermöglicht ein dosiertes Übertreten des Brennmaterials 9 aus dem Fülhaum 11 in den Brennraum 12, sodaß der Verbrennungsvorgang in kontrollierter Weise abläuft.In order to ensure that the combustion is as complete as possible, the combustion chamber 12 tapers towards the top to form a slot-shaped outlet opening 27, via which it is connected to a duct which discharges the combustion exhaust gases and which is not shown in FIG. This slot-shaped outlet opening 27 is created by a fireclay part 1 with lateral spacers 2, which rest on the curved partition 3. Since the filling opening 6 is offset in terms of height from the supply opening 10, there is a siphon effect, due to which the primary air coming into the filling chamber 11 via the filling opening 6 is sucked in only to the extent that it is in the combustion chamber 12 is needed for combustion. The replenishment opening 10 enables a metered passage of the fuel 9 from the filling chamber 11 into the combustion chamber 12, so that the combustion process takes place in a controlled manner.

Da es sehr leicht zu einem Verlegen der Nachschuböffhung 10 durch das Brennmaterial kommen kann, ist erfϊndungsgemäß vorgesehen, daß der Fülhaum 11 ein Fördermittel 7 umfaßt, über welches das Brennmaterial von der Befüllöffhung 6 in den Brennraum 12 forderbar ist. Zumindest ein Teil der Primärluftzufuhröffiiungen 20, 21 mündet dabei derart in den Füllraum 11 mündet, daß der zugeführte Teilstrom der Primärluft durch das Brennmaterial hindurch in den Brennraum 12 gelangt.Since it is very easy for the supply opening 10 to be moved through the fuel, it is provided according to the invention that the filling chamber 11 comprises a conveying means 7, via which the fuel can be conveyed from the filling opening 6 into the combustion chamber 12. At least some of the primary air supply openings 20, 21 open into the filling chamber 11 in such a way that the partial flow of primary air supplied passes through the fuel into the combustion chamber 12.

Bei dem in Fig. 1 gezeigten Ausführungsbeispiel ist als Fördermittel eine - in Gebrauchslage gesehen - sich von der unteren Berandung der Befüllöffhung 6 in den Bereich der Nachschuböffhung 10 schräg nach unten erstreckende Rutschwand 7 ausgebildet, auf deren Oberseite das Brennmaterial von der Befüllöffnung 6 zur Nachschuböffhung 10 und in den Brennraum 12 zu einer dort angeordneten Auffangvorrichtung 8 bewegbar ist, auf der das Brennmaterial 9 verbrannt wird. Anstelle des Rutschbrettes kann aber auch ein Rohr oder eine gewölbte Fläche oder ein Schneckenantrieb als Fördermittel vorgesehen sein.In the exemplary embodiment shown in FIG. 1, a slide wall 7, seen in the position of use, extending obliquely downwards from the lower edge of the filling opening 6 into the region of the supply opening 10, on the top of which the fuel material extends from the filling opening 6 to the supply opening 10 and can be moved into the combustion chamber 12 to a collecting device 8 arranged there, on which the fuel 9 is burned. Instead of the slide board, however, a tube or a curved surface or a worm drive can also be provided as the conveying means.

Die Zufuhröffiiungen 20, 21 für die Primärluft sind derart angeordnet, daß die in den Fülhaum 11 strömende Primärluft sowohl unterhalb als auch oberhalb der Rutschwand 7 zur Nachschuböffhung 10 und über diese in den Brennraum 12 gelangt.The feed openings 20, 21 for the primary air are arranged in such a way that the primary air flowing into the filling chamber 11 reaches both below and above the sliding wall 7 to the supply opening 10 and via this into the combustion chamber 12.

Damit ist einerseits gewährleistet, daß dem auf der Auffangvorrichtung 8 befindlichen Brennmaterial 9 genügend Sauerstoff von oben und von unten zugeführt wird. Die von oben durch die Nachschuböff ung 10 strömende Primärluft verhindert andererseits das Zurückströmen der von unten auf das Brennmaterial 9 auftreffenden Primärluft durch die Nachschuböffhung 10, welches ein Verbrennen des gesamten, im Fülhaum 11 befindlichen Vorrates zur Folge hätte.This ensures on the one hand that the fuel 9 located on the collecting device 8 is supplied with sufficient oxygen from above and below. The primary air flowing from above through the replenishment opening 10 prevents, on the other hand, the back flow of the primary air impinging on the fuel 9 from below through the replenishment opening 10, which would result in burning of the entire supply located in the filling chamber 11.

Zur Förderung der Nachverbrennung der bei der Verbrennung des auf der Auffangvorrichtung 8 verbrennenden Brennmaterials 9 sind weiters in den Brennraum 12 mündende Sekundärluft__ufuhröffhungen 19 vorgesehen, wobei die zugehörige Sekundärluft über einen Sekundärluftkanal 200 vom Primärluftkanal 14 abgezweigt wird. Der Primärluftkanal 14 für die Zufuhr von Primärluft ist in der Wandung des Fülhaumes 11 vorgesehen und ist an seinem Auslaßende mit einem im oberen Bereich der Rutschwand 7 angeordneten Luftverteilungskörper 13 verbunden, über welchen die Primärluft auf die in den oberhalb der Rutschwand 7 befindlichen Teil des Fülhaumes 11 mündenden Luftzuführöffnungen 20 und die in den unterhalb der Rutschwand 7 befindlichen Teil des Füllraumes 11 mündenden Luftzuführöff ungen 21 verteilt wird.In order to promote the afterburning of the combustion material 9 which burns on the collecting device 8, secondary air supply openings 19 opening into the combustion chamber 12 are also provided, the associated secondary air being branched off from the primary air duct 14 via a secondary air duct 200. The primary air duct 14 for the supply of primary air is provided in the wall of the filling chamber 11 and is connected at its outlet end to an air distribution body 13 arranged in the upper region of the sliding wall 7, via which the primary air is directed to the part of the filling room located above the sliding wall 7 11 opening air supply openings 20 and the air supply openings 21 opening into the part of the filling chamber 11 located below the sliding wall 7 is distributed.

Der Luftverteilungskörper kann nach Belieben gestaltet sein, in dem in Fig.l gezeigten Aus__uhrungsbeispiel ist er aus einem Lochblech 13 gebildet. Er bildet zugleich eine Auflagefläche für den oberen Teil der Rutschwand 7.The air distribution body can be designed as desired, in the embodiment shown in FIG. 1 it is formed from a perforated plate 13. It also forms a bearing surface for the upper part of the sliding wall 7.

Die Auffangvorrichtung für das Brennmaterial ist aus einem von der Bodenfläche 18 des Brennraumes 12 beabstandeten Brennerrost 8 mit einer vorzugsweise im Querschnitt V-förmigen Vertiefung 40 gebildet. Diese V-förmige Vertiefung verhindert das Hinausgleiten des brennenden Brennmaterials 9 durch den Druck des auf der Rutschwand 7 nachrutschenden Brennmaterials 9.The collecting device for the fuel is formed from a burner grate 8 spaced from the bottom surface 18 of the combustion chamber 12 and having a recess 40 which is preferably V-shaped in cross section. This V-shaped depression prevents the burning fuel 9 from sliding out due to the pressure of the fuel 9 sliding on the sliding wall 7.

Der Brennerrost 8 ist aus einem Lochblech geformt, sodaß die von unten zuströmende Primärluft direkt auf das Brennmaterial 9 einwirken kann. Begrenzt ist die V- förmige Vertiefung 40 des Brennerrostes 8 an ihren Enden durch schräge, ebenfalls aus Lochblech gebildete Abschlußwände 45, die das seitliche Hinausgleiten des Brennmaterials 9 aus dem Brennerrost 8 verhindern (Fig.3, 5).The burner grate 8 is formed from a perforated plate, so that the primary air flowing in from below can act directly on the fuel 9. The V-shaped recess 40 of the burner grate 8 is delimited at its ends by inclined end walls 45, which are also formed from perforated sheet metal and prevent the fuel material 9 from sliding out laterally from the burner grate 8 (FIGS. 3, 5).

Aus Fig.4 ist ersichtlich, daß der Brennerrost 8 einen Teil eines zweiteiligen Einsatzes bildet, dessen zweiter Teil einen Distanzhalter 26, 27 und einen Handgriff 25 umfaßt, die lösbar mit dem Brennerrost 8 verbindbar sind. Die lösbare Verbindung ist durch eine Kante 41 des Brennerrostes 8 und durch abstehende Winkelfortsätze 29 des Distanzhalters 26, 27 gebildet, in welche die Kante 41 eingepreßt werden kann.It can be seen from FIG. 4 that the burner grate 8 forms part of a two-part insert, the second part of which comprises a spacer 26, 27 and a handle 25, which can be detachably connected to the burner grate 8. The detachable connection is formed by an edge 41 of the burner grate 8 and by protruding angle extensions 29 of the spacer 26, 27, into which the edge 41 can be pressed.

Mit Hilfe des aus Schraubenbolzen 26 und Seitenblechen 27 zusammengesetzten Distanzhalters wird das Aufsetzen des Einsatzes auf der gekrümmten Bodenfläche 18 der erfindungsgemäßen Feuerstätte ermöglicht, wobei über den Handgriff 25 die Positionierung innerhalb der Feuerstätte vorgenommen werden kann. Über vorstehende Ansätze 30 ist der Brennerrost 8 auf der Schamott-Innenseite der Feuerstätte abgestützt (Fig.l).With the aid of the spacer composed of screw bolts 26 and side plates 27, the insert can be placed on the curved bottom surface 18 of the fireplace according to the invention, wherein the positioning within the fireplace can be carried out via the handle 25. The burner grate 8 is supported on the fireclay inside of the fireplace by means of the above projections 30 (FIG. 1).

An der Oberseite des Distanzhalters 26, 27 ist eine querverlaufende, winkelförmige Leiste 22 ausgebildet, die eine Auflagefläche für den unteren Teil der Rutschwand 7 ausbildet. Sobald die Rutschwand 7 auf den zweiteiligen Einsatz aufgesetzt wird, ist dessen Stabilität gegen Verkippen oder Verrutschen gegeben.On the top of the spacer 26, 27, a transverse, angular bar 22 is formed, which has a bearing surface for the lower part of the Forms sliding wall 7. As soon as the sliding wall 7 is placed on the two-part insert, its stability against tilting or slipping is given.

Die Auffangvorrichtung kann aber auch aus Schamott, aus Keramik oder aus einem anderen geeigneten Material gebildet sein, die Form der Auffangvorrichtung kann beliebig sein, solange sie die Funktion des Auffangens des von oben kommenden Brennmaterials erfüllt. However, the collecting device can also be formed from fireclay, from ceramic or from another suitable material, the shape of the collecting device can be of any type, as long as it fulfills the function of collecting the fuel coming from above.
