Definitions
- the present invention relates to a fuel insert for use in fireplace and tiled stoves, heating stoves, fireplace inserts and fire cassettes.
- fireplaces and tiled stoves have always been used to warm living spaces and are increasingly being used again today. This is partly due to the fact that the resulting heat spreads quickly and creates a pleasant atmosphere through subtle lighting.
- Another important aspect of using fireplace and tiled stoves is that the costs of wood and lignite briquettes are lower than those of oil, electricity or gas, making their use economical. Since many older houses have an open fireplace, but this can not be operated safely and the degree of use is too low to be economical, more and more fireplace owners have begun to modernize their fireplace with a fire cassette or a fireplace insert.
- Such heating inserts or heating cassettes for tiled stoves and fireplaces are from the DE 20 2005 021 441 Ul , of the DE 89 10 446 Ul and the DE 39 02 091 A1 known. These heaters can be loaded with natural wood, lignite or briquettes and are available in a variety of training and size on the market.
- a fireplace insert which has a arranged above the ash compartment grate, a delimited Nachverbrennungsraum with separately adjustable secondary air and separately adjustable over- and under-grate primary air flow, wherein between the adjustment of the over-grate primary air flow acted upon by the ember bed preheating available is and the secondary air via distribution channels between the main combustion room and the post-combustion room. Due to the fanned secondary air flow, a high combustion efficiency is achieved.
- a solid fuel heater for tiled stoves comprising a cover of fire resistant material having a flue gas passage and, by far, partially covering the flue opening below the ceiling wall.
- This cover allows an improved flue gas guide in the furnace and a more uniform burnout of the fuel over the entire catch surface.
- the invention is therefore an object of the invention to provide an improved and easy to retrofit fuel insert for use in fireplace and tiled stoves, heating fireplaces, fireplace inserts and fire cassettes.
- the fuel insert formed from a fire-resistant material in the form of a shell can be placed anywhere on the grid and has at least one air passage opening.
- the fuel insert made of fire-resistant material, preferably steel, soapstone, ceramic, especially chamotte, heat-resistant steel or cast iron exists.
- materials such as steel, soapstone, ceramic or chamotte have the ability to store heat. Therefore, may be a long time after the expiration of the fire Heat to be given in the room to be heated.
- the optimized combustion of the fuel and the obstruction of the direct air flow through the grate do not result in too rapid and incomplete burning, which can keep the embers in the ash bed until the next morning.
- the fuel insert is designed in one or more parts.
- the fuel insert can be installed by the user on his own and no specialist is needed for the assembly.
- the burnout insert will be available in all standard size sizes and regardless of the manufacturer's specifications for covering the grate in fireplace or tiled stoves, heating stoves, fireplace inserts and fire cassettes.
- the fuel insert consists of two or more parts, which can each be introduced individually into the furnace. By simple assembly, for example by 'a plug-in system, the items are then connected to each other.
- a multi-part design of the fuel insert also offers the advantage that the transport of the fuel insert, which consists of heavy material or ceramic, is facilitated because the items are separated from each other brought to the fireplace.
- a further embodiment of the invention is that the wall of the fuel insert formed in the form of a shell is higher in one area than in the other areas. It is advantageous that this increase in the wall to the back of the furnace, opposite the fire door shows. By loading the shell is thereby avoided that smaller parts of the fuel fall into the furnace, resulting in contamination thereof. By using the fuel insert with the rear elevated wall thus cleaning and loading of the furnace can be simplified.
- the hearth is not flat, it is advantageous that the fuel insert has large adjustable adjustable feet on the bottom. Due to the individual settings of the Leveling feet is created a level hearth on which the fuel can not escape. This also increases the safety in the refueling.
- the fuel insert has a metallic bellows circumferentially on its lower outer wall, which is connected to the fuel insert via a movable support.
- the movable bellows form a circumferential seal between the fuel insert and the surface on which the fuel insert is placed, allowing the primary air to enter the combustion chamber exclusively through the air intakes of the fuel insert.
- the fuel insert has one or more intake air slides for regulating the air flow through the air passage openings.
- the supply air slides can be used to regulate the amount of air entering the combustion chamber via the grate and the fuel insert. It is provided here that the ventilation from the ash compartment can be completely prevented. It is also envisaged that locking positions are available for the Zu Kunststoffschieber for air flow regulation. In such an embodiment, the example fireplace or tiled stove with insufficient chimney draft can obtain the necessary amount of combustion air on the ashtray. By this regulation, both the incomplete combustion and the resulting Glanzruß realise, and thereby possible Schomsteinbrand prevented.
- the entire surface of the grate can be covered by the bearing surface of the fuel insert formed as a shell, which has at least one air passage opening.
- This is particularly beneficial for wood loading, as uneven and therefore ineffective burnup occurs when too much air is supplied through the grate. Covering by the shell prevents this inadequate combustion of the fuel as less and more targeted air passes through the ashtray via the grate to the fuel in the ash bed of the fuel insert located in the combustion chamber. Through this targeted air flow, a more uniform burnout of the fuel over the entire shell surface can be achieved, resulting in a increased efficiency leads. The fact that less wood is needed to achieve the desired effect, then also produces less fine dust.
- it is envisaged, in the presence of a table grid without support, in which the primary air passes around the shell into the combustion chamber to cover the area not coverable with the shell via one or more plates with matching recesses for fuel use.
- the Bremstoff fondutica has a plurality of air passage openings.
- the air passage opening has an air inlet opening and an air outlet opening, wherein the air inlet opening on the underside of the fuel insert and the air outlet opening in the upper region, in particular on the wall of the shell, is arranged.
- the air outlet opening is aligned with the center of the fuel insert and that the fuel is selectively acted upon with air, resulting in an almost complete combustion of the fuel.
- the almost complete burnup increases the fuel utilization, which results in a reduction of the polluting CO and CO 2 values as well as lower charging costs.
- air outlet openings of the wall which are present at the front (pointing to the fire door) of the fuel insert, not only on the feed, but also on the panoramic window of the fire door are aligned. This allows a disc flushing of the viewing window and counteracts the settling of soot, which prevents the viewing of the flame play.
- the air passage openings have a round cross section and preferably no right angles. This can prevent the deposition of dirt in the air passage openings and allows an improved and directed air flow. As a result, the number of cleanings of the fuel and the ash chamber can be reduced.
- the fuel insert has a glow-retaining lid of fire-resistant material for airtight sealing of the contents of the fuel insert. This ensures that when placed in the evening on the fuel insert, the air supply is reduced so that burning of the fuel is prevented and the following Day the resulting embers can be used with new fuel for reheating. A completely new kindling therefore does not apply.
- the ember holding lid has one or more inlet air slides for regulating the secondary air.
- the ember holding lid can also be used to close the fuel feed.
- the fuel insert can be easily removed from the chimney or stove after cooling. This also facilitates the transport of the fuel when the ash is to be disposed of.
- FIG. 1 It can be seen that the primary air (19) via the air passage openings (10) and through the air outlet openings (16) as secondary air (23) on the center (11) of the formed as a shell (13) and made of fire-resistant material (9) according to the invention fuel insert ( 1) steered.

Abstract
Description
Die vorliegende Erfindung betrifR einen Brennstoffeinsatz für die Benutzung in Kamin- und Kachelöfen, Heizkaminen, Kamineinsätzen und Feuerkassetten.The present invention relates to a fuel insert for use in fireplace and tiled stoves, heating stoves, fireplace inserts and fire cassettes.
Kamin- und Kachelöfen werden seit jeher zum Wärmen von Wohnräumen benutzt und heutzutage wieder vermehrt eingesetzt. Dies beruht zum Teil darauf, dass sich die entstehende Wärme schnell verbreitet und durch dezente Beleuchtung eine angenehme Atmosphäre entsteht. Ein weiterer, wichtiger Aspekt für die Benutzung von Kamin- und Kachelöfen ist, dass die Kosten für Holz und Braunkohlenbriketts niedriger als die für Öl, Strom oder Gas sind, wodurch die Benutzung wirtschaftlich ist. Da viele ältere Häuser einen offenen Kamin besitzen, dieser jedoch nicht gefahrlos dauerhaft betrieben werden kann und der Nutzungsgrad zu gering ist, um wirtschaftlich zu sein, sind immer mehr Kaminbesitzer dazu übergegangen, ihren Kamin mit einer Feuerkassette oder einem Kamineinsatz zu modernisieren.Fireplaces and tiled stoves have always been used to warm living spaces and are increasingly being used again today. This is partly due to the fact that the resulting heat spreads quickly and creates a pleasant atmosphere through subtle lighting. Another important aspect of using fireplace and tiled stoves is that the costs of wood and lignite briquettes are lower than those of oil, electricity or gas, making their use economical. Since many older houses have an open fireplace, but this can not be operated safely and the degree of use is too low to be economical, more and more fireplace owners have begun to modernize their fireplace with a fire cassette or a fireplace insert.
Derartige Heizeinsätze oder Heizkassetten für Kachelöfen und Kamine sind aus der
Der Nachteil bei den üblichen Heizvorrichtungen besteht darin, dass der Verbrennungswirkungsgrad ungenügend ist. Dies kostet nicht nur Geld, sondern belastet zudem die Umwelt, da hohe CO- und CO2-Werte erreicht werden.The disadvantage with the conventional heaters is that the combustion efficiency is insufficient. This not only costs money, but also pollutes the environment, since high CO and CO 2 values are achieved.

Des Weiteren ist aus der
Als nachteilig für den Kamineinsatz, beschrieben in der
Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten und leicht nachrüstbaren Brennstoffeinsatz für die Benutzung in Kamin- und Kachelöfen, Heizkaminen, Kamineinsätzen und Feuerkassetten zu schaffen.The invention is therefore an object of the invention to provide an improved and easy to retrofit fuel insert for use in fireplace and tiled stoves, heating fireplaces, fireplace inserts and fire cassettes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Brennstoffeinsatz aus einem feuerwiderstandsfähigen Material in Form einer Schale ausgebildet, flächendeckend auf dem Rost platzierbar ist und mindestens eine Luftdurchtrittsöffnung aufweist.This object is achieved in that the fuel insert formed from a fire-resistant material in the form of a shell, can be placed anywhere on the grid and has at least one air passage opening.
Da die Platzierung des Brennstoffeinsatzes in einem Ofen oder Kamin oder einem Ofen- oder Kamineinsatz erfolgt, ist es sinnvoll, dass der Brennstoffeinsatz aus feuerwiderstandsfähigem Material, vorzugsweise aus Stahl, Speckstein, Keramik, insbesondere Schamotte, hitzebeständigem Stahl oder Gusseisen, besteht. Neben dem offensichtlichen Vorteil der Lebensdauer besitzen Materialien wie Stahl, Speckstein, Keramik oder Schamotte die Fähigkeit zur Wärmespeicherung. Daher kann noch lange Zeit nach Erlöschen des Feuers Wärme in den zu beheizenden Raum abgegeben werden. Durch den optimierten Abbrand des Brennstoffes und durch die Behinderung des direkten Luftzustroms über den Rost kommt es nicht zu einem zu schnellen und unvollständigen Abbrand, wodurch sich die Glut in dem Aschebett bis zum nächsten Morgen halten kann.Since the placement of the fuel insert takes place in an oven or chimney or a stove or fireplace insert, it makes sense that the fuel insert made of fire-resistant material, preferably steel, soapstone, ceramic, especially chamotte, heat-resistant steel or cast iron exists. In addition to the obvious advantage of durability, materials such as steel, soapstone, ceramic or chamotte have the ability to store heat. Therefore, may be a long time after the expiration of the fire Heat to be given in the room to be heated. The optimized combustion of the fuel and the obstruction of the direct air flow through the grate do not result in too rapid and incomplete burning, which can keep the embers in the ash bed until the next morning.
Bei einem erfindungsgemäßen Brennstoffeinsatz ist zudem vorgesehen, dass der Brennstoffeinsatz ein- oder mehrteilig ausgebildet ist. Dies hat den Vorteil, dass bei der einteiligen Variante der Brennstoffeinsatz durch einfache Platzierung auf dem Rost installierbar ist. Der Brennstoffeinsatz kann selbstständig durch den Benutzer installiert werden und es wird kein Fachmann für die Montage benötigt. Es ist zudem vorgesehen, dass der Brenastoffeinsatz in allen gängigen Größenformaten und unabhängig von Herstellerspezifikationen für die Abdeckung des Rosts in Kamin- oder Kachelöfen, Heizkaminen, Kamineinsätzen und Feuerkassetten erhältlich ist. Im Falle einer kleinen Feuertür ist es weiterhin vorgesehen, dass der Brennstoffeinsatz aus zwei oder mehr Teilen besteht, die jeweils einzeln in den Feuerraum eingeführt werden können. Durch einfache Montage, durch beispielsweise' ein Stecksystem, sind die Einzelteile dann miteinander verbindbar. Eine mehrteilige Ausführung des Brennstoffeinsatzes bietet des Weiteren den Vorteil, dass der Transport des Brennstoffeinsatzes, der aus schwerem Material oder Keramik besteht, erleichtert wird, da die Einzelteile getrennt voneinander zu dem Kamin bringbar sind.In a fuel insert according to the invention, it is additionally provided that the fuel insert is designed in one or more parts. This has the advantage that in the one-piece variant of the fuel insert can be installed by simple placement on the grate. The fuel insert can be installed by the user on his own and no specialist is needed for the assembly. It is also envisaged that the burnout insert will be available in all standard size sizes and regardless of the manufacturer's specifications for covering the grate in fireplace or tiled stoves, heating stoves, fireplace inserts and fire cassettes. In the case of a small fire door, it is further envisaged that the fuel insert consists of two or more parts, which can each be introduced individually into the furnace. By simple assembly, for example by 'a plug-in system, the items are then connected to each other. A multi-part design of the fuel insert also offers the advantage that the transport of the fuel insert, which consists of heavy material or ceramic, is facilitated because the items are separated from each other brought to the fireplace.
Eine weitere Ausgestaltung der Erfindung besteht darin, dass die Wandung des in Form einer Schale ausgebildeten Brennstoffeinsatzes in einem Bereich höher ist als in den übrigen Bereichen. Hierbei ist es von Vorteil, dass diese Erhöhung der Wandung zu der Rückseite des Feuerraums, gegenüberliegend der Feuertür, zeigt. Bei Beschickung der Schale wird hierdurch vermieden, dass kleinere Teile des Brennstoffes in den Feuerraum fallen, was zu Verunreinigung desselben führt. Durch Verwendung des Brennstoffeinsatzes mit der rückseitig erhöhten Wandung kann somit die Reinigung und die Beschickung des Ofens vereinfacht werden.A further embodiment of the invention is that the wall of the fuel insert formed in the form of a shell is higher in one area than in the other areas. It is advantageous that this increase in the wall to the back of the furnace, opposite the fire door shows. By loading the shell is thereby avoided that smaller parts of the fuel fall into the furnace, resulting in contamination thereof. By using the fuel insert with the rear elevated wall thus cleaning and loading of the furnace can be simplified.
Für die sichere Platzierung des Brennstoffeinsatzes in beispielsweise einen älteren Öfen oder Kaminen, deren Feuerstelle nicht eben ist, ist es vorteilhaft, dass der Brennstoffeinsatz an der Unterseite großenverstellbare Stellfüße aufweist. Durch die individuellen Einstellungen der Stellfüße wird eine ebene Feuerstelle geschaffen, auf der der Brennstoff nicht veautschen kann. Dies erhöht zudem die Sicherheit bei dem Brennstoffnachlegen.For the safe placement of the fuel insert in, for example, an older stoves or fireplaces, the hearth is not flat, it is advantageous that the fuel insert has large adjustable adjustable feet on the bottom. Due to the individual settings of the Leveling feet is created a level hearth on which the fuel can not escape. This also increases the safety in the refueling.
Damit die Primärluft bei nicht flächiger Auflage des Brennstoffeinsatzes nicht über den Rost in den Feuerraum entweichen kann, ist erfindungsgemäß vorgesehen, dass der Brennstoffeinsatz an seiner unteren Außenwand umlaufend einen metallischen Faltenbalg aufweist, der über eine bewegliche Halterung mit dem Brennstoffeinsatz verbunden ist. Durch den beweglichen Faltenbalg kommt es zu einem umlaufenden Abschluss zwischen dem Brennstoffeinsatz und der Fläche, auf der der Brennstoffeinsatz platziert ist, wodurch die Primärluft ausschließlich über die Lufteintrittsöffnungen des Brennstoffeinsatzes in den Feuerraum gelangen kann.So that the primary air can not escape via the grate into the combustion chamber when the fuel insert is not flat, it is provided according to the invention that the fuel insert has a metallic bellows circumferentially on its lower outer wall, which is connected to the fuel insert via a movable support. The movable bellows form a circumferential seal between the fuel insert and the surface on which the fuel insert is placed, allowing the primary air to enter the combustion chamber exclusively through the air intakes of the fuel insert.
Bei einem erfindungsgemäßen Brennstoffeinsatz ist zudem vorgesehen, dass der Brennstoffeinsatz einen oder mehrere Zuluftschieber für die Luftdurchflussregulation durch die Luftdurchtrittsöffnungen aufweist. Über die Zuluftschieber kann die Luftmenge, die über den Rost und den Brennstoffeinsatz in den Feuerraum gelangt, reguliert werden. Es ist hierbei vorgesehen, dass die Belüftung aus dem Ascheraum auch gänzlich verhindert werden kann. Es ist zudem vorgesehen, dass Feststellpositionen für die Zuluftschieber für die Luftdurchflussregulation vorhanden sind. Bei einer derartigen Ausführung kann der beispielsweise Kamin- oder Kachelofen bei unzureichendem Schornsteinzug die notwendige Verbrennungsluftmenge über den Ascheraum beziehen. Durch diese Regulierung wird sowohl die unvollständige Verbrennung und dadurch entstehende Glanzrußbildung, sowie dadurch möglicher Schomsteinbrand, verhindert.In a fuel insert according to the invention, it is additionally provided that the fuel insert has one or more intake air slides for regulating the air flow through the air passage openings. The supply air slides can be used to regulate the amount of air entering the combustion chamber via the grate and the fuel insert. It is provided here that the ventilation from the ash compartment can be completely prevented. It is also envisaged that locking positions are available for the Zuluftschieber for air flow regulation. In such an embodiment, the example fireplace or tiled stove with insufficient chimney draft can obtain the necessary amount of combustion air on the ashtray. By this regulation, both the incomplete combustion and the resulting Glanzrußbildung, and thereby possible Schomsteinbrand prevented.
Es ist des Weiteren zu der Erfindung gehörig, dass mit der Auflagefläche des als Schale ausgebildeten Brennstoffeinsatzes, die mindestens eine Luftdurchtrittsöffnung aufweist, die gesamte Rost-Oberfläche bedeckbar ist. Dies ist im Besonderen von Vorteil für die Beschickung mit Holz, da ein ungleichmäßiger und somit ineffektiver Abbrand entsteht, wenn zu viel Luft über den Rost zugeführt wird. Die Abdeckung durch die Schale verhindert diesen ungenügenden Abbrand des Brennstoffes, da weniger und gezielt Luft durch den Ascheraum über den Rost auf den Brennstoff im Aschebett des Brennstoffeinsatzes, der sich im Feuerraum befindet, gelangt. Durch diese gezielte Luftführung kann ein gleichmäßigerer Durchbrand des Brennstoffes über die gesamte Schalenfläche erreicht werden, was zu einem erhöhten Wirkungsgrad führt. Dadurch, dass weniger Holz benötigt wird, um die gewünschte Wirkung zu erlangen, entsteht dann auch weniger Feinstaub. Zudem ist vorgesehen, bei Vorhandensein eines Tafelrosts ohne Auflage, bei dem die Primärluft um die Schale herum in den Feuerraum gelangt, die mit der Schale nicht abdeckbare Fläche über eine oder mehrere Platten mit passenden Aussparungen für den Brennstoffeinsatz abzudecken.It is further associated with the invention that the entire surface of the grate can be covered by the bearing surface of the fuel insert formed as a shell, which has at least one air passage opening. This is particularly beneficial for wood loading, as uneven and therefore ineffective burnup occurs when too much air is supplied through the grate. Covering by the shell prevents this inadequate combustion of the fuel as less and more targeted air passes through the ashtray via the grate to the fuel in the ash bed of the fuel insert located in the combustion chamber. Through this targeted air flow, a more uniform burnout of the fuel over the entire shell surface can be achieved, resulting in a increased efficiency leads. The fact that less wood is needed to achieve the desired effect, then also produces less fine dust. In addition, it is envisaged, in the presence of a table grid without support, in which the primary air passes around the shell into the combustion chamber to cover the area not coverable with the shell via one or more plates with matching recesses for fuel use.
Bei einem erfindungsgemäßen Brennstoffeinsatz ist es nützlich, dass der Brermstoffeinsatz mehrere Luftdurchtrittsöffnungen aufweist. Die Luftdurchtrittsöffnung weist eine Lufteintrittsöffnung und eine Luftaustrittsöffnung auf, wobei die Lufteintrittsöffnung auf der Unterseite des Brennstoffeinsatzes und die Luftaustrittsöffnung im oberen Bereich, insbesondere an der Wandung der Schale, angeordnet ist. Bei einem erfindungsgemäßen Brennstoffeinsatz ist es daher möglich, dass die Luftaustrittsöffnung auf die Mitte des Brennstoffeinsatzeses ausgerichtet ist und dass der Brennstoff gezielt mit Luft beaufschlagbar ist, was in einem fast vollständigen Abbrand des Brennstoffes resultiert. Durch den fast vollständigen Abbrand wird die Brennstoffverwertung erhöht, welches in einer Reduzierung der umweltbelastenden CO- und CO2-Werte sowie niedrigeren Beschickungskosten resultiert. Des Weiteren ist vorgesehen, dass zudem Luftaustrittsöffnungen der Wandung, die an der Vorderseite (zu der Feuertür zeigend) des Brennstoffeinsatzes vorhanden sind, nicht nur auf die Beschickung, sondern auch auf die Panoramascheibe der Feuertür ausgerichtet sind. Dies ermöglicht eine Scheibenspülung des Sichtfensters und wirkt dem Absetzen von Ruß entgegen, welches das Betrachten des Flammenspiels verhindert.In a fuel insert according to the invention, it is useful that the Bremstoffeinsatz has a plurality of air passage openings. The air passage opening has an air inlet opening and an air outlet opening, wherein the air inlet opening on the underside of the fuel insert and the air outlet opening in the upper region, in particular on the wall of the shell, is arranged. In a fuel insert according to the invention, it is therefore possible that the air outlet opening is aligned with the center of the fuel insert and that the fuel is selectively acted upon with air, resulting in an almost complete combustion of the fuel. The almost complete burnup increases the fuel utilization, which results in a reduction of the polluting CO and CO 2 values as well as lower charging costs. Furthermore, it is provided that also air outlet openings of the wall, which are present at the front (pointing to the fire door) of the fuel insert, not only on the feed, but also on the panoramic window of the fire door are aligned. This allows a disc flushing of the viewing window and counteracts the settling of soot, which prevents the viewing of the flame play.
Zu der Erfindung ist gehörig, dass die Luftdurchtrittsöffnungen einen runden Querschnitt und vorzugsweise keine rechten Winkel aufweisen. Dies kann die Ablagerung von Schmutz in den Luftdurchtrittsöffnungen verhindern und erlaubt eine verbesserte und gerichtete Luftführung. In Folge dessen kann die Anzahl der Reinigungen des Brennstoffeinsatzes sowie des Ascheraumes reduziert werden.It is associated with the invention that the air passage openings have a round cross section and preferably no right angles. This can prevent the deposition of dirt in the air passage openings and allows an improved and directed air flow. As a result, the number of cleanings of the fuel and the ash chamber can be reduced.
Bei einem erfindungsgemäßen Brennstoffeinsatz ist es weiterhin nützlich, dass der Brennstoffeinsatz einen Gluthaltedeckel aus feuerwidentandsfähigem Material zum luftdichten Abschließen des Inhalts des Brennstoffeinsatzes aufweist. Hierdurch wird erreicht, dass, wenn man diesen am Abend auf den Brennstoffeinsatz platziert, die Luftzufuhr dermaßen reduziert wird, dass ein Abbrand des Brennstoffs verhindert wird und am folgenden Tag die entstandene Glut mit neuem Brennstoff zum Weiterheizen genutzt werden kann. Ein gänzlich neues Entfachen entfällt somit.In a fuel insert according to the present invention, it is further useful that the fuel insert has a glow-retaining lid of fire-resistant material for airtight sealing of the contents of the fuel insert. This ensures that when placed in the evening on the fuel insert, the air supply is reduced so that burning of the fuel is prevented and the following Day the resulting embers can be used with new fuel for reheating. A completely new kindling therefore does not apply.
Es ist weiterhin vorteilhaft, wenn der Gluthaltedeckel einen oder mehrere Zuluftschieber zur Regulation der Sekundärluft aufweist. Durch die Regulation der Luftmenge kann der Abbrand, sowie die Brenndauer und daraus folgende Wärmeabgabe, sowie die Glutlebedauer eingestellt werden.It is furthermore advantageous if the ember holding lid has one or more inlet air slides for regulating the secondary air. By regulating the amount of air burnup, as well as the burning time and consequent heat release, as well as the Glutlebedauer can be adjusted.
Im Falle, dass man den Brennstoff bewusst erlöschen lässt, kann der Gluthaltedeckel des Weiteren zum Verschließen des Brennstoffeinsatzes genutzt werden. Der Brennstoffeinsatz kann nach Erkalten einfach aus dem Kamin oder Ofen entfernt werden. Dies erleichtert auch den Transport des Brennstoffeinsatzes wenn die Asche entsorgt werden soll.In the event that the fuel is deliberately extinguished, the ember holding lid can also be used to close the fuel feed. The fuel insert can be easily removed from the chimney or stove after cooling. This also facilitates the transport of the fuel when the ash is to be disposed of.
Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen erläutert.In the following, the invention will be explained with reference to exemplary embodiments.
