Description

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 Primärluftzufuhröffnungen münden, welche gegenüber der Nachschuböffnung nach oben höhenversetzt angeordnet sind, wobei der Füllraum ein Fördermittel umfaßt, über welches das Brennmaterial von der Befüllöffnung in den Brennraum förderbar ist.The invention relates to a fireplace with a via a filling with Fuel fillable filling space and one with this over a supply opening connected combustion chamber, wherein in the filling chamber primary air supply openings open, which are arranged vertically offset from the supply opening upwards, wherein the Filling chamber comprises a conveying means, via which the fuel from the filling opening in the combustion chamber is recoverable.

Gepreßtes Brennmaterial kann aus verschiedenartigen Grundstoffen, wie Holz, Karton, Papier o.ä. 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.Pressed fuel can be made of various basic materials, such as wood, Cardboard, paper or similar consist. For example, wood pellets are made of natural wood, which is produced from woodworking industry sawdust and sawdust. Without the addition of binders, the untreated raw material is under high pressure compacted and pelleted. The resulting cylindrical rolls have low residual moisture and a high calorific value. These positive material properties can be but with conventional fireplaces very difficult to use because of the small size of the compacts the supply of oxygen to the point where the combustion takes place, is impeded. The result is one associated with poor emissions Combustion inside the fireplace.

Die US 4 517 903 A offenbart eine Feuerstätte, bei der ein Brennmaterial aus einem Fülltrichter mittels eines Schneckenantriebs und einer Rohrrutsche in den Brennraum forderbar ist. Parallel zum Schneckenantrieb ist ein Luftzufuhrkanal angeordnet, der ebenfalls mit der Rohrrutsche verbunden ist. Im Brennraum wird die zugeführte Luft durch das Brennmaterial geleitet und anschließend in einem Wärmetauscher Nutzluft erwärmt.US 4 517 903 A discloses a fireplace in which a fuel from a hopper by means of a screw drive and a tube slide into the combustion chamber is required. Parallel to the worm drive an air supply channel is arranged, which also connected to the tube slide. In the combustion chamber, the air supplied through the Passed fuel and then heated in a heat exchanger useful air.

Aus der FR 1 030 504 A geht eine Feuerstelle für Koks hervor, bei der der Füllraum über dem Brennraum angeordnet ist. Die Primärluft strömt seitlich des Füllraums durch eine Öffnung in die Feuerstätte und anschließend in die Brennkammer, wobei der Luftstrom aufgespalten wird.FR 1 030 504 A discloses a hearth for coke, in which the Filling space is arranged above the combustion chamber. The primary air flows laterally of the filling space through an opening in the fireplace and then into the combustion chamber, the Air flow is split.

Die AT 395 207 B betrifft eine Vorrichtung zur bedarfsabhängigen Regelung der Zufuhr von festen Brennstoffen. Dabei ist in den Brennstoffkanal ein Hohlkörper eingebaut, der mittels einer beweglichen Klappe von dem Brennstoff verschließbar ist, wobei der im Hohlkörper vorherrschende Druck von der Stellung der Klappe abhängt. Mit dem Hohlkörper ist ein Druckschalter verbunden.AT 395 207 B relates to a device for demand-dependent control the supply of solid fuels. Here, in the fuel channel is a hollow body installed, which is closed by means of a movable flap of the fuel, wherein the prevailing pressure in the hollow body depends on the position of the flap. With the Hollow body is connected to a pressure switch.

Die DE 826 950 C offenbart eine Halbgasfeuerung, wobei bei dem Übergang zwischen der vergasenden Brennstoffschicht und dem Gasverbrennungsraum fingerähnliche Erhebungen vorgesehen sind, die eine Verwirbelung des Luftstromes bewirken. Weiters sind in diesem Bereich Ausströmungsöffnungen aus einem Oberluftkanal angeordnet.DE 826 950 C discloses a semi-gas firing, wherein at the transition between the gasifying fuel layer and the gas combustion space finger-like Elevations are provided, which cause a turbulence of the air flow. Further are arranged in this area outflow openings from an upper air duct.

Aus der US 5 522 327 A geht eine Feuerstätte für Pellets mit einem aus einem Lochblech geformten Rost hervor.From US 5 522 327 A, a hearth for pellets goes with one of a Perforated metal shaped rust.

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.The object of the invention is therefore to provide a fireplace of the aforementioned To specify type, with a good controllable combustion, especially of pressed Fuel can be made and which is very low Emission levels during combustion allows.

Erfindungsgemäß wird dies dadurch erreicht, daß zumindest ein Teil der Primärluftzufuhröffnungen derart in den Füllraum mündet, daß ein Teilstrom der Primärluft - in an sich bekannter Weise - durch das Brennmaterial hindurch in den Brennraum gelangt und ein weiterer Teilstrom der Primärluft dem im Brennraum befindlichen Brennmaterial von unten zugeführt wird.According to the invention this is achieved in that at least part of the Primary air supply openings opens into the filling space such that a partial flow of the primary air - in a conventional manner - passes through the fuel into the combustion chamber and a further partial flow of the primary air to the combustion chamber located in the combustion material of is supplied below.

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 this way, the fuel passes through the conveyor into the Combustion chamber, wherein at the same time the flowing from top to bottom primary air through the Pass fuel through to the upper part of the combustion chamber located in the glowing nest can and thereby ensures complete combustion, with always so much air is sucked in, as is needed for the combustion.

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 Befüllöffnung in den Bereich der Nachschuböffnung schräg nach unten erstreckt und auf deren Oberseite das Brennmaterial von der Befüllöffnung zur Nachschuböffnung und in den Brennraum zu einer dort angeordneten Auffangvorrichtung bewegbar ist.In a further embodiment of the invention can be provided that the Funding is formed by a sliding wall, which - seen in the use position - of the lower boundary of the filling opening in the region of the supply opening obliquely extends below and on top of which the fuel from the filling to Supply 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 subsidy generated in this way enables the promotion of the Fuel alone by gravity and therefore does not require any external energy for their Business. Alternatively to the slide board can also be a pipe or a curved surface as Serve subsidies.

Gemäß einer Weiterbildung der Erfindung kann vorgesehen sein, daß die Primärluftzufuhröffnungen 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 one embodiment of the invention can be provided that the Primary air supply openings are arranged such that the flowing into the filling space Primary air both below and above the sliding wall to the supply opening 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 Nachschuböffnung 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 fördert die Verfeuerung des im Brennraum befindlichen Brennmaterials, durch die Trennung von Brennraum und Füllraum wird aber immer nur der in die Auffangvorrichtung gelangende Teil des Brennmaterials verbrannt und eine sofortige Verbrennung des gesamten im Füllraum befindlichen Vorratsmaterials verhindert.With the help of the sliding wall, the filling space is in an upper and a lower Subdivided part, so that the primary air passed over both parts of the room to the supply opening is only the top of the sliding wall but with fuel is occupied, so that at the Bottom can flow primary air without obstruction in the combustion chamber. Of the This achievable high primary air flow promotes the combustion of the combustion chamber located fuel, through the separation of the combustion chamber and filling but is only the part of the fuel that reaches the collecting device is incinerated and an immediate combustion of the entire stored material in the filling space prevented.

In weiterer Ausbildung der Erfindung können in den Brennraum mündende Sekundärluftzufuhröffnungen vorgesehen sein, welche die Nachverbrennung von bei der Verbrennung entstehenden Gasen fördert.In a further embodiment of the invention can be opening into the combustion chamber Secondary air supply openings may be provided which the afterburning of the Combustion of resulting gases promotes combustion.

Um eine in Form eines Baukastensystems zusammensetzbare Feuerstätte zu schaffen, kann vorgesehen sein, daß der Brennraum und der Füllraum durch eine gewölbte Trennwand voneinander getrennt sind, die an ihrem unteren Ende unter Ausbildung der Nachschuböffnung 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. To a composable in the form of a modular system fireplace to create, it can be provided that the combustion chamber and the filling space by a curved Partition are separated from each other, at its lower end to form the Supply opening is spaced from a concave curved bottom surface. By the Special shaping of the partition wall can reduce the induced draft, with which the primary air is sucked through the fireplace, to be improved.

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 Auslaßöffnung und die höhenversetzte Anordnung von Nachschuböffnung und Füllöffnung erreichbare Syphonwirkung ermöglicht eine Verbrennung mit sehr geringen Abgaswerten.In a further embodiment of the invention, the combustion chamber can be upwards to taper to a slot-shaped outlet opening, via which the combustion chamber with a Combustion gases dissipating duct is connected. The through the slot or nozzle-shaped outlet opening and the height-offset arrangement of replenishment opening and Fill opening achievable siphon effect allows 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 Luftzuführöffnungen und die in den unterhalb der Rutschwand befindlichen Teil des Brennraumes mündenden Lunzuführöfmungen verteilt wird.To allow a supply of primary air above and below the sliding wall too reach, can be provided in a further embodiment of the invention that in the Füllraumwandung a channel for the supply of primary air is provided, which at its Outlet end arranged with a in the upper part of the sliding wall Air distribution body is connected, via which the primary air to the in the above Sliding wall located part of the combustion chamber opening air supply openings and in opening the located below the sliding wall part of the combustion chamber Lunzuführöfmungen is distributed.

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 even distribution of the primary air can in the further training of the Invention be achieved in that the air distribution body of a perforated plate is formed, which forms a bearing surface for the upper part of the sliding wall.

Gemäß einer weiteren Ausftihrungsform 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 another embodiment of the invention, the Collecting device for the fuel from one of the bottom surface of the combustion chamber spaced burner grate with a preferably in cross-section V-shaped recess be formed. The V-shaped recess prevents excessive slipping of the Fuel in 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 be formed from a perforated plate and it can be the V-shaped recess of the burner grate be limited at their ends by oblique, formed from perforated plate end walls. 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 may be part of a Two-part insert form, the second part of a spacer and a handle comprises, which are releasably connectable to each other.

Durch die Nachschuböffnung 10 gelangt das Brennmaterial 9 in den Brennraum 12 und wird dort verfeuert.At the lower end of the partition wall 3 is a supply opening 10 through Spacing of the partition wall 3 formed by a concave curved bottom surface 18. Through the supply opening 10, the fuel 9 enters the combustion chamber 12 and is burned there.

    Um eine möglichst vollständige Verbrennung zu gewährleisten, verjüngt sich der Brennraum 12 nach oben hin zu einer schlitzförmigen Auslaßöffnung 27, über die dieser mit einem die Verbrennungsabgase ableitenden Kanal verbunden ist, der in Fig.1 nicht dargestellt ist. Diese schlitzförmige Auslaßöffnung 27 entsteht durch ein Schamott-Teil 1 mit seitlichen Distanzstützen 2, die auf der gewölbten Trennwand 3 ruhen. To ensure the most complete combustion, it tapers the combustion chamber 12 upwards to a slot-shaped outlet opening 27, via this is connected to a combustion exhaust gases dissipating channel, not in Fig.1 is shown. This slot-shaped outlet opening 27 is formed by a fireclay part 1 with lateral distance supports 2, which rest on the curved partition 3.

    Da die Befüllöffnung 6 gegenüber der Nachscbuböffnung 10 nach oben höhenversetzt ist, ergibt sich eine Syphonwirkung, aufgrund der die über einen im Bereich der Befüllöffnung 6 in den Füllraum 11 mündenden Primärluftkanal 14 kommende Primärluft nur in dem Ausmaß angesaugt wird, in dem sie im Brennraum 12 zur Verbrennung benötigt wird. Die Nachschuböffnung 10 ermöglicht ein dosiertes Übertreten des Brennmaterials 9 aus dem Füllraum 11 in den Brennraum 12, sodaß der Verbrennungsvorgang in kontrollierter Weise abläuft.Since the filling opening 6 with respect to the Nachscbuböffnung 10 upwards offset, results in a siphon effect, due to the one in the field of Filling opening 6 in the filling chamber 11 opening primary air duct 14 incoming primary air only is sucked to the extent that it is needed in the combustion chamber 12 for combustion. The replenishment opening 10 allows a metered crossing of the fuel 9 from the Filling chamber 11 in the combustion chamber 12, so that the combustion process in a controlled manner expires.

    Da es sehr leicht zu einem Verlegen der Nachschuböffnung 10 durch das Brennmaterial kommen kann, ist erfindungsgemäß vorgesehen, daß der Füllraum 11 ein Fördermittel 7 umfaßt, über welches das Brennmaterial von der Befüllöffnung 6 in den Brennraum 12 förderbar ist. Zumindest ein Teil der Primärluftzufuhröffnungen 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 to a laying of the supply opening 10 through the Fuel can come, the invention provides that the filling chamber 11 a Conveying means 7, via which the fuel from the filling opening 6 in the Combustion chamber 12 is conveyed. At least part of the primary air supply openings 20, 21 opens in such a way in the filling chamber 11 opens, that the supplied partial flow of the primary air through the fuel passes through 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 Befüllöffnung 6 in den Bereich der Nachschuböffnung 10 schräg nach unten erstreckende Rutschwand 7 ausgebildet, auf deren Oberseite das Brennmaterial von der Befüllöffnung 6 zur Nachschuböffnung 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 embodiment shown in Fig. 1 is as a conveying a - in Operating position seen - from the lower boundary of the filling opening 6 in the area the supply opening 10 obliquely downwardly extending sliding wall 7 formed on the upper side of the fuel from the filling opening 6 to the supply opening 10 and in the combustion chamber 12 is movable to a collecting device 8 arranged there, on which the Fuel 9 is burned. Instead of the slide board but can also be a pipe or a curved surface or a worm drive be provided as a subsidy.

    Die Zufuhröffnungen 20, 21 für die Primärluft sind derart angeordnet, daß die in den Füllraum 11 strömende Primärluft sowohl unterhalb als auch oberhalb der Rutschwand 7 zur Nachschuböffnung 10 und über diese in den Brennraum 12 gelangt.The supply openings 20, 21 for the primary air are arranged such that the in the filling space 11 flowing primary air both below and above the sliding wall 7 to the supply opening 10 and passes through 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 Nachschuböffnung 10 strömende Primärluft verhindert andererseits das Zurückströmen der von unten auf das Brennmaterial 9 auftreffenden Primärluft durch die Nachschuböffnung 10, welches ein Verbrennen des gesamten, im Füllraum 11 befindlichen Vorrates zur Folge hätte.This is on the one hand ensures that the on the collecting device. 8 located fuel 9 sufficient oxygen is supplied from above and from below. On the other hand, the primary air flowing from above through the supply opening 10 prevents the backflow of the impinging from below on the fuel 9 primary air through the Replenishment opening 10, which is a burning of the entire, located in the filling space 11 Stock would result.

    Zur Förderung der Nachverbrennung der bei der Verbrennung des auf der Auffangvorrichtung 8 verbrennenden Brennmaterials 9 sind weiters in den Brennraum 12 mündende Sekundärluftzufuhröffnungen 19 vorgesehen, wobei die zugehörige Sekundärluft über einen Sekundärluftkanal 200 vom Primärluftkanal 14 abgezweigt wird. To promote the afterburning of the combustion of the on the Collecting device 8 burning fuel 9 are further into the combustion chamber 12th opening secondary air supply openings 19 are provided, wherein the associated secondary air is branched off from the primary air channel 14 via a secondary air channel 200.

    Der Primärluftkanal 14 für die Zufuhr von Primärluft ist in der Wandung des Füllraumes 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 Füllraumes 11 mündenden Luftzuführöffnungen 20 und die in den unterhalb der Rutschwand 7 befindlichen Teil des Füllraumes 11 mündenden LunzuführöShungen 21 verteilt wird.The primary air duct 14 for the supply of primary air is in the wall of the Filling chamber 11 is provided and is at its outlet end with a in the upper part of the Sliding wall 7 arranged air distribution body 13 is connected, via which the primary air on the in the above the sliding wall 7 located part of the filling space 11 opening Air supply openings 20 and located in the below the sliding wall 7 part of the Füllraumes 11 opening LunzuführöShungen 21 is distributed.

    Der Luftverteilungskörper kann nach Belieben gestaltet sein, in dem in Fig.1 gezeigten Ausführungsbeispiel ist er aus einem Lochblech 13 gebildet. Er bildet zugleich eine Auflagefläche für den oberen Teil der Rutschwand 7.The air distribution body may be designed as desired, in which in Fig.1 shown embodiment, it is formed of a perforated plate 13. He forms at the same time a support 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 from one of the Floor surface 18 of the combustion chamber 12 spaced burner grate 8 with a preferably in Cross-section V-shaped recess 40 is formed. This V-shaped recess prevents this Sliding out of the burning fuel 9 by the pressure of the slide on the 7th slipping fuel 9.

    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 of a perforated plate, so that from below inflowing primary air can act directly on the fuel 9. Limited is the V-shaped Recess 40 of the burner grate 8 at their ends by oblique, also off Perforated sheet formed end walls 45, the lateral sliding out of the fuel. 9 from the burner grate 8 prevent (Fig.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.From Fig.4 it can be seen that the burner grate 8 is part of a two-part Insert forms, the second part of a spacer 26, 27 and a handle 25th includes, which are releasably connectable to the burner grate 8. The detachable connection is through an edge 41 of the burner grate 8 and by protruding angular extensions 29 of the Spacer 26, 27 formed, in 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.1).With the help of the screw 26 and side plates 27th Composite spacer will be the placement of the insert on the curved Bottom surface 18 of the hearth of the invention allows, over the handle 25th the positioning within the fireplace can be made. About above Lugs 30, the burner grate 8 is supported on the firelight inside the fireplace (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.At the top of the spacer 26, 27 is a transverse, angular ledge 22 is formed, which has a support surface for the lower part of the Sliding wall 7 forms.
