Description

Die Erfindung betrifft einen Heizkessel mit einem Kesselgehäuse , mit einer im Kesselgehäuse vorgesehenen Brennkammer, die einen Brennkammerdeckel mit einem Rauchgaszutritt, einen dem Rauchgaszutritt gegenüberliegenden Brennkammerboden und zwei an den Brennkammerdeckel anschließende und einander gegenüberliegende Brennkammerseitenwände aufweist, welche einander in Richtung des Brennkammerbodens v-förmig zulaufend angeordnet sind und jeweils mindestens einen Seitenwandstein, insbesondere Schamottestein, aufweisen, und mit mindestens einer am Kesselgehäusebefestigten Abstützung, die ein erstes und zweites Auflager aufweist, welche jeweils mindestens eine Auflagefläche ausbilden, auf welche Auflageflächen die Seitenwandsteine der Brennkammerseitenwände (9 und 10) aufliegen.The invention relates to a boiler with a boiler housing, with a provided in the boiler housing combustion chamber having a combustion chamber lid with a Rauchgaszutritt, the Rauchgaszutritt opposite combustion chamber floor and two adjoining the combustion chamber lid and opposing combustion chamber side walls, which converge towards each other in the direction of the combustion chamber floor v-shaped are arranged and each having at least one side wall brick, in particular firebrick, and having at least one support on the boiler housing having a first and second supports, which each form at least one bearing surface on which bearing surfaces the side wall stones of the combustion chamber side walls (9 and 10) rest.

Um eine v-förmige Brennkammer in einem Heizkessel zu realisieren, ist es aus dem Stand der Technik bekannt ( EP2314947A2 ), eine am Kesselgehäuse befestigte Abstützung vorzusehen, auf welcher die aus Schamotte bestehenden Seitenwandsteine der Brennkammerseitenwände aufsitzen. Diese Abstützung wird von zwei an der Kesselseitenwand befestigten Auflagern ausgebildet, welche über dem Brennkammerboden eine horizontale Auflagefläche für die Seitenwandsteine der Brennkammerseitenwände, auf denen Seitenwandsteine aufliegen, ausbilden. Nachteilig haben dabei diese als Winkel ausgeführten Auflager nicht nur das Gewicht der Seitenwandsteine, sondern auch jenes des Brennkammerdeckels, welcher auf den Seitenwandsteinen aufsitzt und zusätzlich durch das abzubrennende Stückgut gewichtsbelastet sein kann, abzutragen. Aufgrund der dadurch entstehenden vergleichsweise hohen Gewichtsbelastung der Seitenwandsteine - und damit auch der Abstützung - bedarf es eines vergleichsweise hohen konstruktiven Aufwands am Heizkessel.In order to realize a V-shaped combustion chamber in a heating boiler, it is known from the prior art ( EP2314947A2 ) to provide a fixed to the boiler housing support, on which sit the chamotte existing sidewall stones of the combustion chamber side walls. This support is formed by two attached to the boiler side wall supports, which form above the combustion chamber floor a horizontal support surface for the side wall stones of the combustion chamber side walls, on which side wall stones rest. The disadvantage of this run as an angle support not only the weight of the sidewall stones, but also that of the combustion chamber lid, which sits on the side wall stones and can be weight-loaded by the abzubrennende cargo in addition, ablate. Due to the resulting relatively high weight load of the sidewall stones - and thus the support - it requires a relatively high design effort on the boiler.

Außerdem kann eine derart ausgebildete Brennkammer eine freie Wärmedehnung der Seitenwandsteine durch Heizbelastung nicht sicherstellen, womit die Lebensdauer der Brennkammer und damit die Standfestigkeit des Heizkessels vermindert werden. Hinzu kommt, dass es bei einem Tausch abgebrannter Seitenwandsteine eines vollständigen Auseinandernehmens der Brennkammer bedarf, was wiederum den Wartungsaufwand solche eines Heizkessels erheblich erhöht.In addition, such a trained combustion chamber can not ensure a free thermal expansion of the sidewall stones by heating load, whereby the service life of the combustion chamber and thus the stability of the boiler can be reduced. In addition, when exchanging spent sidewall bricks, a complete disassembly of the combustion chamber is required, which in turn significantly increases the maintenance requirements of such a boiler.

Die Erfindung hat sich daher die Aufgabe gestellt, ausgehend vom eingangs geschilderten Stand der Technik, einen Heizkessel mit einer v-förmigen Brennkammer konstruktiv derart zu auszubilden, dass sowohl dessen Standfestigkeit, als auch dessen Wartungsfreundlichkeit verbessert werden.The invention is therefore based on the object, starting from the above-described prior art, a boiler with a V-shaped combustion chamber constructively to train so that both its stability, as well as its ease of maintenance can be improved.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die Abstützung ein drittes Auflager aufweist, auf dem der Brennkammerdeckel aufliegt, und dass die Auflageflächen des ersten und zweiten Auflagers, auf denen die Seitenwandsteine lose aufliegen, schräg verlaufen.The invention achieves the stated object in that the support has a third support, on which rests the combustion chamber lid, and that the bearing surfaces of the first and second support on which the side wall stones rest loosely, obliquely.

Weist die Abstützung ein drittes Auflager auf, auf dem der Brennkammerdeckel aufliegt, können damit die Seitenwandsteine vom Brennkammerdeckel und auch von dem darauf lastenden Stückgut gewichtsentlastet werden. Dies kann nicht nur Vorteile in Hinblick auf die mögliche Ausbildung der Seitenwandsteine bringen, sondern auch die Konstruktion der Abstützung der Brennkammer vereinfachen. Zudem kann es damit möglich werden, die Wärmedehnung der Seitenwandsteine erleichtert zuzulassen, da diese zumindest von anderen Teilen der Brennkammer gewichtsentlastet sind. Im Zuge dessen wird kann auch die Beständigkeit der Brennkammer verbessert werden. Vor allem aber in Kombination mit dem Merkmal, dass die Auflageflächen des ersten und zweiten Auflagers, auf denen die Seitenwandsteine lose aufliegen, schräg verlaufen, können sich diese Vorteile besonders entfalten. Durch dieses schräge und unter Gewichtseigenbelastung lose Aufliegen der Seitenwandsteine können nämlich beispielsweise innere Spannungen durch thermische Belastungen deutlich reduziert werden. Die erfindungsgemäße Brennkammer mit in Richtung des Brennkammerbodens einander v-förmig zulaufenden Brennkammerseitenwänden kann sohin durch die schrägen Auflageflächen nicht nur beständig, sondern durch das lose Aufliegen der Seitenwandsteine auch besonders wartungsfreundlich ausgebildet sein - etwa in jenem Fall, dass abgebrannte Seitenwandsteine auszuwechseln sind, beispielsweise über eine Brennkammertür am Heizkessel. Die erfindungsgemäße, konstruktive Änderung der Abstützung der Brennkammer kann sohin zu einem konstruktiv einfachen und auch besonders standfesten - aber auch zu einem vergleichsweise einfach zu wartenden - Heizkessel führen.If the support has a third support, on which the combustion chamber cover rests, then the side wall stones can be weight-relieved of the combustion chamber cover and also of the cargo bearing thereon. This can not only bring advantages in terms of the possible formation of the sidewall stones, but also simplify the construction of the support of the combustion chamber. In addition, it may thus be possible to facilitate the thermal expansion of the sidewall stones, as they are at least weight-relieved of other parts of the combustion chamber. In the course of this, the durability of the combustion chamber can also be improved. But especially in combination with the feature that the bearing surfaces of the first and second support on which the side wall stones rest loosely, run obliquely, these advantages can be particularly unfold. By this oblique and under weight inherent load loose resting the sidewalls namely, for example, internal stresses can be significantly reduced by thermal loads. The combustion chamber according to the invention with in the direction the combustion chamber floor each other v-shaped tapered combustion chamber side walls can thus not only resistant by the inclined support surfaces, but also be designed to be particularly easy to maintain by the loose resting of the sidewall stones - such as in that case that burned sidewalls are replaced, for example, a combustion chamber door on the boiler. The inventive, constructive change in the support of the combustion chamber can thus lead to a structurally simple and particularly stable - but also to a comparatively easy to maintain - boiler.

Langlebigkeit und Wartungsfreundlichkeit der Seitenwandsteine können weiter erhöht werden, wenn die Abstützung ein viertes und fünftes Auflager mit schrägen Auflageflächen aufweist, wobei die Seitenwandsteine der gegenüberliegenden Brennkammerseitenwände mit ihren unteren Steinenden auf der schrägen Auflagefläche des ersten oder zweiten Auflagers und mit deren oberen Steinenden auf der schrägen Auflagefläche des vierten oder fünften Auflagers lose aufliegen. Zudem kann solch eine Abstützung der Seitenwandsteine für eine besonders genaue Positionierung der Seitenwandsteine sorgen, was zur Verbesserung von Standfestigkeit und Funktion der Brennkammer beitragen kann.Longevity and ease of maintenance of the side wall stones can be further increased if the support has a fourth and fifth support with oblique bearing surfaces, wherein the sidewalls of the opposite combustion chamber side walls with their lower stone ends on the inclined bearing surface of the first or second support and with their upper stone ends on the oblique Loosely rest support surface of the fourth or fifth support. In addition, such a support of the sidewall stones provide for a particularly accurate positioning of the sidewall stones, which can contribute to the improvement of stability and function of the combustion chamber.

Sitzen die Seitenwandsteine auf dem Kesselgehäuse auf, kann eine standfeste und sichere Lagerfixierung der Seitenwandsteine erreicht werden, ohne dass es einer Befestigung der Seitenwandsteine bedarf. Dies kann die Wartungsfreundlichkeit des Heizkessels weiter verbessern.If the side wall stones sit on the boiler housing, a stable and secure bearing fixation of the side wall stones can be achieved without the need for fixing the side wall stones. This can further improve the serviceability of the boiler.

Der Heizkessel kann konstruktiv weiter vereinfacht werden, indem die Abstützung mindestens eine erste Profilschiene mit wenigstens einem schrägen Profilschenkel aufweist, der die schräge Auflagefläche des ersten oder zweiten Auflagers ausbildet. Zudem kann eine erste Profilschiene eine standfeste Verbindung der Abstützung mit dem Kesselgehäuse sicherstellen.The boiler can be structurally further simplified by the support having at least one first rail with at least one oblique profile leg, which forms the inclined support surface of the first or second support. In addition, a first rail to ensure a stable connection of the support with the boiler housing.

Weist die erste Profilschiene zwei aufeinander v-förmig zulaufende Profilschenkel auf, welche die Auflageflächen des ersten oder zweiten Auflagers ausbilden, kann auf konstruktive einfache Weise eine Lagerstelle für die aufeinander zulaufenden Seitenwandsteine geschaffen werden. Zudem kann solch eine Schiene zur genauen und einfachen relativen Positionierung der Seitenwandsteine zueinander beitragen, was unter anderem eine exakt konstruierte Brennkammer für einen reproduzierbar herstellbaren Heizkessel sicherstellen kann.If the first profiled rail has two profiled legs running towards each other in a v-shape, which form the bearing surfaces of the first or second support, a bearing point for the converging sidewall bricks can be created in a constructive simple manner. In addition, such a rail for accurate and easy relative positioning of the sidewall stones contribute to each other, which can ensure, inter alia, a precisely constructed combustion chamber for a reproducible manufacturable boiler.

Die Positionierung der Seitenwandsteine und damit die Konstruktionsgenauigkeit der Brennkammer können weiter erhöht werden, wenn die erste Profilschiene einen horizontalen Steg aufweist, an dem die Seitenwandsteine der einander gegenüberliegenden Brennkammerseitenwände aufsitzen. Des Weiteren kann diese zusätzliche horizontale Auflage dafür sorgen, dass ein eventuelles Spaltmaß am oberen Ende der Seitenwandsteine aufgrund ihrer Wärmelängsdehnung sicher reduziert wird. Auf diese Weise können ein besonders gasdichter Anschluss der Seitenwandsteine in der Brennkammer sichergestellt und auch den Wirkungsgrad des Heizkessels erhöht werden.The positioning of the sidewall blocks and thus the design accuracy of the combustion chamber can be further increased if the first rail has a horizontal web on which rest the sidewall blocks of the opposing combustion chamber side walls. Furthermore, this additional horizontal support ensure that any gap at the top of the sidewall stones is safely reduced due to their thermal expansion. In this way, a particularly gas-tight connection of the sidewall stones can be ensured in the combustion chamber and also the efficiency of the boiler can be increased.

Die Abstützung kann konstruktiv vereinfacht werden, wenn die Abstützung eine zweite und eine dritte Profilschiene aufweist, die je eine schräge Auflagefläche des vierten oder fünften Auflagers und je eine Auflagefläche des dritten Auflagers ausbilden. Zudem kann damit eine genaue Relativpositionierung der Seitenwandsteine gegenüber dem Brennkammerdeckel sichergestellt werden, was an der Brennkammer eine hohe Maßgenauigkeit gewährleisten kann.The support can be structurally simplified if the support has a second and a third rail, each forming an inclined support surface of the fourth or fifth support and each bearing surface of the third support. In addition, a precise relative positioning of the sidewall blocks relative to the combustion chamber cover can thus be ensured, which can ensure a high degree of dimensional accuracy at the combustion chamber.

Der Brennkammerboden kann auch von den Seitenwandsteinen ausgebildet werden, indem die Seitenwandsteine der einander gegenüberliegenden Brennkammerseitenwände am Scheitel deren v-förmigen Verlaufs aneinander angrenzen und dort den Brennkammerboden ausbilden. Derart ist es möglich, die Herstellung der Brennkammer erblich vereinfachen und zudem einen konstruktiv einfachen Heizkessel zur Verfügung zu stellen.The combustion chamber floor can also be formed by the side wall blocks by the side wall stones of the opposing combustion chamber side walls adjoin one another at the apex of their v-shaped course and form the combustion chamber floor there. Thus, it is possible to simplify the manufacture of the combustion chamber hereditary and also to provide a structurally simple boiler available.

Der Konstruktionsaufbau der Brennkammer kann weiter vereinfacht werden, wenn die Brennkammer eine Brennkammerrückwand mit mindestens einem Rückwandstein, insbesondere Schamottestein, aufweist, der an die Seitenwandsteine angrenzt und dort die Brennkammer abschließt, und dass die Brennkammer einen Saugzuganschluss an der, der Brennkammerrückwand gegenüberliegenden Brennkammervorderseite aufweist.The design structure of the combustion chamber can be further simplified if the combustion chamber has a combustion chamber rear wall with at least one rear wall brick, in particular firebrick, which adjoins the side wall stones and closes the combustion chamber, and that the combustion chamber has a Saugzuganschluss at the combustion chamber rear wall opposite combustion chamber front side.

Wird solch ein Saugzuganschluss abschnittsweise von den gegenüberliegenden Brennkammerseitenwänden begrenzt, kann damit der Konstruktionsaufwand am Heizkessel weiter vermindert werden.If such a Saugzuganschluss limited in sections by the opposite combustion chamber side walls, so that the construction cost of the boiler can be further reduced.

Besonders vorteilhafte Strömungsverhältnisse für das Rauchgas in der Brennkammer können ermöglicht werden, wenn der Saugzuganschluss dreieckförmig verlaufend ausgebildet ist.Particularly advantageous flow conditions for the flue gas in the combustion chamber can be made possible if the Saugzuganschluss is formed triangular extending.

Die Wartung des Heizkessels kann erheblich vereinfacht werden, wenn Heizkessel einen mit einer Brennkammertür verschließbaren Zugang zur Brennkammer aufweist, der zum Austauschen der Seitenwandsteine ausgebildet ist. Über diesen Zugang können beispielsweise abgebrannte Seitenwandsteine einfach entnommen und durch neue Seitenwandsteine ersetzt werden. Dies kann zudem durch die lose Lagerung der Seitenwandsteine besonders handhabungsfreundlich sein.The maintenance of the boiler can be greatly simplified if the boiler has a lockable with a combustion chamber door access to the combustion chamber, which is designed to replace the sidewall stones. For example, this access can be used to simply remove spent sidewall stones and replace them with new sidewall stones. This can also be particularly easy to handle by the loose storage of sidewalls.

According to the FIGS. 1 . 2a . 2 B and 3 For example, a boiler 1, namely a wood gasifier, shown, which receives a filling chamber 3 for charging the boiler 1 with lumpy solid fuel 4 in his boiler housing 2 - which is based on an indicated firewood in Fig. 1 is shown. Below the filling space 3, a combustion chamber 5 is arranged, which is connected via a provided in the combustion chamber cover 6 of the combustion chamber 5 Rauchgaszutritt 7, which is covered by a grate, not shown, with the filling space 3, to burn the flue gas 7.1 and / or nachverbrennen. The combustion chamber 5 also has a combustion chamber floor 8 and two combustion chamber side walls 9, 10 lying opposite one another, which are lined by chamotte of side wall bricks 9.1, 10.1 which are cuboidal in the exemplary embodiment.

Wie insbesondere der Fig. 1 zu entnehmen, sind die Brennkammerseitenwände 9, 10 in Richtung des Brennkammerbodens 8 einander v-förmig verlaufend ausgebildet, was im Querschnitt unterhalb des Füllraums 3 eine v-förmige Brennkammer 5 ergibt.How the particular Fig. 1 can be seen, the combustion chamber side walls 9, 10 are formed in the direction of the combustion chamber floor 8 each other v-shaped extending, resulting in cross-section below the filling space 3, a v-shaped combustion chamber 5.

Die Brennkammer 5 ist über eine Abstützung 11 mit dem Kesselgehäuse 2 verbunden. Hierzu weist die Abstützung 11 ein erstens Auflager 12 und zweites Auflager 13 auf, welche jeweils Auflageflächen 12.1 und 13.1 ausbilden, auf denen die Seitenwandsteine 9.1, 10.1 der einander gegenüberliegenden Brennkammerseitenwände 9, 10 aufliegen.The combustion chamber 5 is connected via a support 11 to the boiler housing 2. For this purpose, the support 11 has a first support 12 and a second support 13, which respectively form support surfaces 12.1 and 13.1, on which the side wall stones 9.1, 10.1 of the combustion chamber side walls 9, 10 lying opposite each other rest.

Erfindungsgemäß verlaufen die Auflageflächen 12.1 und 13.1 des ersten und zweiten Auflagers 12, 13 schräg - also zur Horizontalen und Vertikalen geneigt. Auf diesen schrägen Auflageflächen 12.1 und 13.1 liegen die Seitenwandsteine 9.1, 10.1 lose auf und gewichtsbelasten die Auflageflächen 12.1 und 13.1, insbesondere in der Fig. 2b zu erkennen. Durch dieses lose Aufliegen kann auch bei wechselnden Wärmebelastungen eine ausreichende Wärmedehnung der Seitenwandsteine 9.1, 10.1 zugelassen werden, womit diese Seitenwandsteine 9.1, 10.1 spannungsarm gehalten werden, was wiederum zu einer standfesten und beständigen Brennkammer 5 führt. Zudem zeigt die Abstützung 11 ein drittes Auflager 14 mit einer horizontalen Auflagefläche 14.1, auf welcher der Brennkammerdeckel 6 aufliegt. Dies stellt die Seitenwandsteine 9.1, 10.1 gegenüber dem Gewicht des Brennkammerdeckels 6 frei, was eine weitere Spannungsentlastung der Seitenwandsteine 9.1, 10.1 dar- und damit deren Beständigkeit sicherstellt. Zumal dann die Seitenwandsteine 9.1, 10.1 nur aufgrund deren Eigengewichts auf den schrägen Auflageflächen 12.1 und 13.1 lose an bzw. damit aufliegen müssen. Die erfindungsgemäße Abstützung 11 der Brennkammer 5 führt daher zu einer erhöhten Standfestigkeit und verbesserten Wartungsfreundlichkeit des Heizkessels 1.According to the invention, the bearing surfaces 12.1 and 13.1 of the first and second supports 12, 13 run obliquely - that is inclined to the horizontal and vertical. On these inclined bearing surfaces 12.1 and 13.1 are the side wall stones 9.1, 10.1 loose and weight bearing surfaces 12.1 and 13.1, in particular in the Fig. 2b to recognize. Due to this loose seating, a sufficient thermal expansion of the side wall stones 9.1, 10.1 can be allowed even with changing heat loads, whereby these side wall stones 9.1, 10.1 are held tension-free, which in turn leads to a stable and stable combustion chamber 5 leads. In addition, the support 11 shows a third support 14 with a horizontal support surface 14.1, on which the combustion chamber cover 6 rests. This sets the side wall stones 9.1, 10.1 relative to the weight of the combustion chamber lid 6 free, which further stress relief of the sidewall stones 9.1, 10.1 dar- and thus ensures their durability. Especially since then the side wall stones 9.1, 10.1 only because of their own weight on the inclined bearing surfaces 12.1 and 13.1 must loosely rest on or so. The support 11 of the combustion chamber 5 according to the invention therefore leads to increased stability and improved ease of maintenance of the boiler. 1

In der Fig. 1 ist zudem erkennbar, dass die Abstützung 11 ein viertes Auflager 15 und fünftes Auflager 16 je mit schrägen Auflageflächen 15.1, 16.1 aufweist. Diese zusätzlichen Auflager 15, 16 bilden jeweils eine obere lose Lagerung für je einen Seitenwandstein 9.1, 10.1 aus. Damit können die Seitenwandsteine 9.1, 10.1 bei thermischer Expansion und Kontraktion besonders spannungsfrei gehalten werden, da durch das lose Aufliegen der oberen Steinenden 17, 18 der Seitenwandsteine 9.1, 10.1 auf den schrägen Auflageflächen 15.1, 16.1 für eine ausreichende Bewegungsfreiheit gesorgt werden kann. Da außerdem die unteren Steinenden 19, 20 der Seitenwandsteine 9.1, 10.1 auf den schrägen Auflageflächen 12.1, 13.1 des ersten und zweiten Auflagers 12, 13 lose aufliegen, können die Seitenwandsteine 9.1, 10.1 handhabungsfreundlich ausgewechselt werden, was die Wartungsfreundlichkeit des Heizkessels 1 verbessert.In the Fig. 1 It can also be seen that the support 11 has a fourth support 15 and a fifth support 16, each with oblique bearing surfaces 15.1, 16.1. These additional supports 15, 16 each form an upper loose storage for one side wall brick 9.1, 10.1. Thus, the side wall stones 9.1, 10.1 can be kept particularly free of stress during thermal expansion and contraction, as can be ensured by the loose resting of the upper stone ends 17, 18 of the side wall stones 9.1, 10.1 on the inclined support surfaces 15.1, 16.1 for sufficient freedom of movement. In addition, since the lower stone ends 19, 20 of the sidewall stones 9.1, 10.1 loosely rest on the inclined bearing surfaces 12.1, 13.1 of the first and second supports 12, 13, the sidewalls 9.1, 10.1 can be replaced easy to handle, which improves the ease of maintenance of the boiler 1.

In Fig. 1 und Fig. 2b ist zu erkennen, dass die Abstützung 11 eine erste Profilschiene 30.1 mit zwei einander v-förmig zulaufenden Profilschenkeln 21, 22 aufweist. Diese schrägen Profilschenkel 21, 22 bilden die schrägen Auflageflächen 12.1, 13.1 des ersten Auflagers 12 und des zweiten Auflagers 13 aus. Die derartige erste Profilschiene 30.1 weist zudem einen horizontalen Steg 23 auf, an dem die beiden Seitenwandsteine 9.1, 10.1 der einander gegenüberliegenden Brennkammerseitenwände 9, 10 und damit auf dem Kesselgehäuse 2 aufsitzen. Dies erleichtert die Positionierung der Seitenwandsteine 9.1, 10.1. Die erste Profilschiene 30.1 ist mit Kesselboden 2.1 des Kesselgehäuses 2 fest verbunden, und zwar wie beispielsweise dargestellt über eine Schraubverbindung 25.In Fig. 1 and Fig. 2b It can be seen that the support 11 has a first profiled rail 30.1 with two profile legs 21, 22 which tap each other in a V-shape. These oblique profile legs 21, 22 form the oblique bearing surfaces 12.1, 13.1 of the first support 12 and the second support 13. The first profiled rail 30.1 of this type also has a horizontal web 23 on which the two side wall stones 9.1, 10.1 of the opposing combustion chamber side walls 9, 10 and thus on the boiler housing 2 are seated. This facilitates the positioning of the side wall stones 9.1, 10.1. The first rail 30.1 is with Kesselboden 2.1 of the boiler housing 2 firmly connected, as shown for example via a screw 25th

In Fig. 1 und Fig. 2a ist zu erkennen, dass die Abstützung 11 auch eine zweite Profilschiene 30.2 und eine dritte Profilschiene 30.3 aufweist. So bildet die zweite Profilschiene 30.2 sowohl eine schräge Auflagefläche 15.1 des vierten Auflagers 15 als auch eine horizontale Auflagefläche 14.1 des dritten Auflagers 14 aus. Die dritte Profilschiene 30.3 bildet sowohl eine schräge Auflagefläche 16.1 des fünften Auflagers 16 als auch eine Auflagefläche 14.1 des dritten Auflagers 14 aus. Damit ist eine besondere konstruktive Einfachheit erreicht und eine exakte Brennkammer 5 sichergestellt. Die zweite und dritte Profilschiene 30.2, 30.3 sind jeweils auf einer Kesselwand 2.1 der einander gegenüberliegenden Kesselwänden 2.2 des Kesselgehäuses 2 befestigt, beispielsweise mit den Kesselwänden 2.2 verschweißt.In Fig. 1 and Fig. 2a It can be seen that the support 11 also has a second rail 30.2 and a third rail 30.3. Thus, the second profile rail 30.2 forms both an oblique support surface 15.1 of the fourth support 15 and a horizontal support surface 14.1 of the third support 14. The third rail 30.3 forms both an inclined support surface 16.1 of the fifth support 16 and a support surface 14.1 of the third support 14. For a special structural simplicity is achieved and ensures an exact combustion chamber 5. The second and third rails 30.2, 30.3 are each mounted on a boiler wall 2.1 of the opposite boiler walls 2.2 of the boiler housing 2, for example, welded to the boiler walls 2.2.

Im Allgemeinen wird erwähnt, dass zur Befestigung der Profilschienen 30.1, 30.2, 30.3 andere (lösbare oder feste) Verbindungen vorstellbar sind.In general, it is mentioned that for the attachment of the rails 30.1, 30.2, 30.3 other (detachable or fixed) connections are conceivable.

Nach Fig. 2b ist zudem die gegenseitige Abstützung der Seitenwandsteine 9.1, 10.1 an den unteren Steinenden 19, 20 gezeigt. Dadurch grenzen die Seitenwandsteine 9.1, 10.1 der einander gegenüberliegenden Brennkammerseitenwände 9, 10 am Scheitel 24 des v-förmigen Verlaufs aneinander an und bilden dort den Brennkammerboden 8 aus. Eine konstruktiv besonders einfach ausgeführte Brennkammer 5 ist damit geschaffen.To Fig. 2b In addition, the mutual support of the side wall stones 9.1, 10.1 at the lower stone ends 19, 20 shown. As a result, the side wall stones 9.1, 10.1 of the opposing combustion chamber side walls 9, 10 adjoin one another at the apex 24 of the V-shaped course and form the combustion chamber floor 8 there. A structurally particularly simple running combustion chamber 5 is thus created.

Die Brennkammer 5 weist auch eine geschlossene Brennkammerrückwand 26 mit einem v-förmigen Rückwandstein 27 aus Schamotte auf. Der Rückwandstein 27 grenzt an die Seitenwandsteine 9.1, 10.1 an und schließt dort die Brennkammer 5 gasdicht ab.The combustion chamber 5 also has a closed combustion chamber rear wall 26 with a V-shaped back wall brick 27 made of chamotte. The rear wall brick 27 adjoins the side wall stones 9.1, 10.1 and there closes the combustion chamber 5 gas-tight.

Auf der Brennkammervorderseite 28, die der Brennkammerrückwand 26 gegenüberliegt, ist der dreieckförmig verlaufende Saugzuganschluss 29 vorgesehen - wie dieser in den Figuren 1 strichliert eingezeichnet ist. Der Saugzuganschluss 29 wird von den einander gegenüberliegenden Brennkammerseitenwänden 9, 10 und dem Brennkammerboden 8 begrenzt, wodurch eine besonders vorteilhafte Führung des Rauchgases 7.1 durch die Brennkammer 5 und in weiterer Folge an beiden Seiten der Brennkammer 5 zurück zum Wärmetauscher 31 ermöglicht wird.On the combustion chamber front side 28, which is opposite the combustion chamber rear wall 26, the triangular-shaped Saugzuganschluss 29 is provided - as this in the FIGS. 1 dashed lines is drawn. The Saugzuganschluss 29 is bounded by the opposing combustion chamber side walls 9, 10 and the combustion chamber 8, whereby a particularly advantageous guidance of the flue gas 7.1 through the combustion chamber 5 and subsequently on both sides of the combustion chamber 5 back to the heat exchanger 31 is made possible.

Des Weiteren ist der Fig. 3 zu entnehmen, dass die Brennkammerseitenwand 9 mit drei nebeneinander vorgesehenen, quaderförmige Seitenwandsteinen 9.1, 9.2, 9.3 ausgekleidet ist. Die derartige Auskleidung besteht auch bei der Brennkammerseitenwand 10, was allerdings nicht dargestellt ist.Furthermore, the Fig. 3 can be seen that the combustion chamber side wall 9 is lined with three side by side provided, cuboid side wall stones 9.1, 9.2, 9.3. Such a lining also exists in the combustion chamber side wall 10, which is not shown.

In den Figuren 1 bis 3 ist zudem zu entnehmen, dass ist dem Kesselgehäuse 2 bekanntermaßen eine Einhausung 32 zugeordnet bzw. weist diese auf, welche Einhausung 32 beispielsweise eine wärmedämmende Funktion hat.In the FIGS. 1 to 3 In addition, it can be seen that the boiler housing 2 is known to be associated with an enclosure 32 or has it, which enclosure 32 has a heat-insulating function, for example.

Zudem weist, wie in Fig. 3 zu erkennen, der Heizkessel 1 eine offenbare Brennkammertür 33 auf, mit der ein Zugang 34 zur Brennkammer 5 verschlossen wird. Über diese Brennkammertür 33 ist die Brennkammer 5 beispielsweise für Reinigungszwecke zugänglich. Zudem ist der Zugang 34 in Form und Größe zum Austauschen der Seitenwandsteine 9.1, 9.2, 9.3 bzw. 10.1, 10.2, 10.3 ausgebildet. Dadurch können abgebrannte Seitenwandsteine 9.1, 9.2, 9.3 bzw. 10.1, 10.2, 10.3 einfach herausgezogen und durch neue Seitenwandsteine 9.1, 9.2, 9.3 bzw. 10.1, 10.2, 10.3 durch Einschieben dieser ersetzt werden, was durch die profilschienenförmigen Abstützungen 11 erheblich erleichtert wird. Hierzu wird im Allgemeinen erwähnt, dass die Profilschienen 30.1, 30.2, 30.2 mit deren Längsrichtungen vorzugsweise auf den Zugang 34 ausgerichtet sind.In addition, as in Fig. 3 to recognize the boiler 1 an open combustor door 33, with an access 34 to the combustion chamber 5 is closed. About this combustion chamber door 33, the combustion chamber 5 is accessible for cleaning purposes, for example. In addition, the access 34 is formed in shape and size for exchanging the side wall stones 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3. As a result, spent sidewalls 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3 can simply be pulled out and replaced by new sidewall stones 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3 by inserting them, which is considerably facilitated by the profiled rail-shaped supports 11. For this purpose, it is generally mentioned that the profile rails 30.1, 30.2, 30.2 are preferably aligned with their longitudinal directions on the access 34.
