Abstract

The boiler has a heat exchanger (7) with a housing (9) provided in vertically held tube bundles (10-12) for guidance of exhaust gases from a combustion chamber (2). A flow chamber (4) is attached at a return fuel line (6) of a heat transfer medium and provided between the combustion chamber and a mantle (3) that partially encloses the combustion chamber. The flow chamber stays in flow-connection with the housing of the heat exchanger over passage openings (18) such that the housing upwardly overlaps with the combustion chamber, and tubes of the tube bundles end in the combustion chamber.

Description

Die Erfindung bezieht sich auf einen Heizkessel mit einer Brennkammer und einem einen Vor- und einen Rücklauf für einen Wärmeträger aufweisenden Wärmetauscher, der ein an einer Umfangsseite der Brennkammer angeordnetes Gehäuse zur Aufnahme des Wärmeträgers und dieses Gehäuse in mehreren Zügen vertikal durchsetzende Rohrbündel zur Führung der Abgase aus der Brennkammer umfasst.The invention relates to a boiler with a combustion chamber and a heat exchanger having a forward and a return heat exchanger having a arranged on a peripheral side of the combustion chamber housing for receiving the heat carrier and this housing in several passes vertically penetrating tube bundles for guiding the exhaust gases from the combustion chamber.

Zur Erwärmung eines Wärmeträgers, üblicherweise Wasser, mit Hilfe der fühlbaren Abwärme der in der Brennkammer eines Heizkessels anfallenden Abgase ist es bekannt ( AT 005 583 U1 ), einen Wärmetauscher mit einem Gehäuse einzusetzen, dem der zu erwärmende Wärmeträger über einen Rücklauf zugeführt und über einen Vorlauf abgezogen wird. Das auf einer Umfangsseite der Brennkammer vorgesehen Gehäuse wird von Rohrbündeln zur Abgasführung durchsetzt, die wenigstens zwei Züge bilden, nämlich einen abwärts und einen aufwärts gerichteten Zug. Abgase aus der Brennkammer werden über eine obere Umlenkkammer dem abwärts gerichteten Zug und über eine untere Umlenkkammer dem aufwärts gerichteten Zug zugeführt und mit Hilfe eines Saugzuggebläses abgezogen. Während des Durchströmens der das Gehäuse durchsetzenden Rohre der Rohrbündel wird der Wärmeträger im Gehäuse durch Wärmeaustausch erwärmt. Allerdings ist die Regelung solcher Wärmetauscher wegen der vergleichsweise großen Masse des zu erwärmenden Wärmeträgers träge, was sich vor allem bei Heizkesseln für stückeligen Brennstoff, insbesondere für Holzpellets nachteilig bemerkbar macht.For heating a heat transfer medium, usually water, with the aid of the sensible waste heat of the exhaust gases accumulating in the combustion chamber of a boiler, it is known ( AT 005 583 U1 ), to use a heat exchanger with a housing to which the heat transfer medium to be heated is supplied via a return and withdrawn via a supply line. The housing provided on a circumferential side of the combustion chamber is penetrated by tube bundles for the exhaust system, which form at least two trains, namely a downward and an upward train. Exhaust gases from the combustion chamber are fed via an upper deflection chamber the downward train and a lower deflection chamber the upward train and withdrawn by means of a Saugzuggebläses. During the flow through the tubes of the tube bundle passing through the housing, the heat transfer medium in the housing is heated by heat exchange. However, the regulation of such heat exchangers is sluggish because of the comparatively large mass of the heat carrier to be heated, which is disadvantageous especially in boilers for lumpy fuel, especially for wood pellets.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Heizkessel der eingangs geschilderten Art so auszugestalten, dass sich eine vorteilhafte Regelung des Wärmetauschers ergibt.The invention is therefore based on the object, a boiler of the type described in such a way that there is an advantageous control of the heat exchanger.

Die Erfindung löst die gestellt Aufgabe dadurch, dass zwischen der Brennkammer und einem die Brennkammer zumindest teilweise umschließenden Mantel ein an den Rücklauf des Wärmeträgers angeschlossener Strömungsraum vorgesehen ist, der über Durchtrittsöffnungen mit dem Gehäuse des Wärmetauschers in Strömungsverbindung steht, dass das Gehäuse die Brennkammer oben übergreift und dass die Rohre des das Gehäuse in diesem Bereich durchsetzenden Rohrbündels in die Brennkammer münden.The invention solves the problem posed by the fact that between the combustion chamber and a combustion chamber at least partially enclosing jacket is provided connected to the return of the heat transfer flow space, which communicates via passages with the housing of the heat exchanger in flow communication that the housing overlaps the combustion chamber above and that the tubes of the tube bundle passing through the housing in this area open into the combustion chamber.

Durch den Strömungsraum zwischen der Brennkammer und dem die Brennkammer zumindest teilweise umschließenden Mantel werden in an sich bekannter Weise zusätzliche Wärmetauscherflächen gewonnen, die wegen des Anschlusses dieses Strömungsraumes an den Rücklauf des Wärmeträgers für eine rasche Aufwärmung des Wärmeträgers aus dem kalten Rücklauf sorgen. Dazu kommt, dass sich über die Durchtrittsöffnungen zwischen diesem Strömungsraum und dem Gehäuse des eigentlichen Wärmetauschers bei geschickter Anordnung der Druchtrittsöffnungen eine Konvektionsströmung einstellen kann, die die vorteilhafte Erwärmung des Wärmeträgers unterstützt. Eine solche vorteilhafte Anordnung der Durchtrittsöffnungen ergibt sich immer dann, wenn der Strömungsraum zwischen der Brennkammer und dem sie umschließenden Mantel sowohl in einem unteren als auch in einem oberen Bereich über die Durchtrittsöffnungen mit dem Gehäuse in Strömungsverbindung steht.Through the flow space between the combustion chamber and the combustion chamber at least partially enclosing jacket additional heat exchanger surfaces are obtained in a conventional manner, which provide for the connection of this flow space to the return of the heat carrier for a rapid warming of the heat carrier from the cold return. In addition, a convection flow can be established via the passage openings between this flow space and the housing of the actual heat exchanger with a clever arrangement of the discharge openings, which supports the advantageous heating of the heat carrier. Such an advantageous arrangement of the passage openings always results when the flow space between the combustion chamber and the jacket enclosing it is in flow communication with the housing both in a lower and in an upper region via the passage openings.

Es bilden sich daher insgesamt einfache Regelungsverhältnisse für den Wärmeaustausch aus, die ein vergleichsweise geringes Aufnahmevolumen für den Wärmeträger im Bereich des Wärmetauschers und damit eine erhebliche Gewichtseinsparung ermöglichen, ohne einen Leistungsverlust des Wärmetauschers in Kauf nehmen zu müssen. In diesem Zusammenhang ist darauf hinzuweisen, dass durch den unmittelbaren Anschluss der Rohre des Rohrbündels für den ersten Zug des Wärmetauschers an die Brennkammer aufgrund des die Brennkammer oben übergreifenden Gehäuses die Abgase unmittelbar nach ihrem Austritt aus der Brennkammer ohne eine sonst erforderliche Umlenkung unter optimaler Ausnützung des Platzangebotes für die Erwärmung des Wärmeträgers genützt werden können.It therefore form a total of simple control conditions for the heat exchange, which allow a comparatively small capacity for the heat transfer in the heat exchanger and thus a significant weight saving, without having to accept a loss of power of the heat exchanger in purchasing. In this regard, it should be noted that by the direct connection of the tubes of the tube bundle for the first train of the heat exchanger to the combustion chamber due to the combustion chamber above cross-housing the exhaust gases can be used immediately after their exit from the combustion chamber without an otherwise required deflection with optimum utilization of space for the heating of the heat carrier.

Ist der Vorlauf des Wärmeträgers an einen das Gehäuse des Wärmetauschers zumindest teilweise umschließenden Sammelraum angeschlossen, der sich in den Bereich von die Züge der Rohrbündel oben verbindenden Umlenkkammern erstreckt, so kann die fühlbare Abwärme der Abgase aus der Brennkammer auch im Bereich dieser Umlenkkammern zur Erwärmung des Wärmeträgers herangezogen werden.If the flow of the heat carrier to a housing of the heat exchanger at least partially enclosing plenum connected, which extends in the range of the trains of the tube bundle above connecting deflection chambers, the sensible waste heat of the exhaust gases from the combustion chamber in the region of these deflection chambers for heating the Be used heat carrier.

Der Heizkessel gemäß dem dargestellten Ausführungsbeispiel weist eine über einen Stufenrost 1 angeordnete Brennkammer 2 auf, die teilweise von einem Mantel 3 umschlossen wird. Zwischen dem Mantel 3 und der Brennkammer 2 ergibt sich ein Strömungsraum 4, der über eine Anschlusskammer 5 mit dem Rücklauf 6 eines Wärmeträgers, üblicherweise Wasser, verbunden ist, das mit Hilfe eines über die Abgase aus der Brennkammer 2 beheizten Wärmetauschers 7 erwärmt wird. Der Vorlauf für den Wärmeträger ist mit 8 bezeichnet. Der Wärmetauscher 7 umfasst ein an einer Umfangsseite der Brennkammer 2 angeordnetes Gehäuse 9 zur Aufnahme des Wärmeträgers sowie das Gehäuse 9 vertikal in mehreren Zügen durchsetzende Rohrbündel 10, 11 und 12, die über obere und unter Umlenkkammern 13 und 14 miteinander verbunden sind. Die Anordnung ist dabei so getroffen, dass das Gehäuse 9 die Brennkammer 2 oben übergreift, sodass die Rohre des Rohrbündels 10 des ersten Zuges in die Brennkammer 2 münden, wie dies insbesondere den Fig. 1 und 2 zu entnehmen ist. Über die Umlenkkammer 13 werden die Abgase durch das Rohrbündel 11 eines abwärtsführenden Zuges zur Umlenkkammer 14 und von der Umlenkkammer 14 in einen durch eine Trennwand 15 von der Umlenkkammer 13 getrennten Sammelraum 16 geführt, der über ein Abgasrohr 17 mit einem Sauggebläse verbunden ist.The boiler according to the illustrated embodiment has a combustion chamber 2 arranged above a step grate 1, which is partially enclosed by a jacket 3. Between the jacket 3 and the combustion chamber 2 results in a flow chamber 4, which is connected via a connection chamber 5 with the return 6 of a heat carrier, usually water, which is heated by means of a heated via the exhaust gases from the combustion chamber 2 heat exchanger 7. The flow for the heat carrier is designated 8. The heat exchanger 7 comprises a arranged on a peripheral side of the combustion chamber 2 housing 9 for receiving the heat carrier and the housing 9 vertically in several passes passing through tube bundles 10, 11 and 12, which are interconnected via upper and under deflection chambers 13 and 14 are. The arrangement is made such that the housing 9, the combustion chamber 2 overlaps above, so that the tubes of the tube bundle 10 of the first train open into the combustion chamber 2, as in particular the Fig. 1 and 2 can be seen. About the deflection chamber 13, the exhaust gases are passed through the tube bundle 11 of a downward leading train to the deflection chamber 14 and of the deflection chamber 14 in a separated by a partition wall 15 from the deflection chamber 13 collecting chamber 16 which is connected via an exhaust pipe 17 with a suction fan.

Die Strömungsverbindung zwischen dem Strömungsraum 4 innerhalb des die Brennkammer 2 teilweise umschließenden Mantels 3 und dem Gehäuse 9 des Wärmetauschers 7 erfolgt durch Durchtrittsöffnungen 18, die sowohl in einem unteren als auch in einem oberen Bereich des Strömungsraumes 4 vorgesehen sind. Aufgrund dieser Strömungsverbindung zwischen dem Gehäuse 9 des Wärmetauschers 7 und dem Strömungsraum 4 kann sich zwischen dem Gehäuse 9 und dem Strömungsraum 4 eine Konvektionsströmung für den Wärmeträger aufbauen, die für eine vorteilhafte Erwärmung des Wärmeträgers auch dann sorgt, wenn kein erwärmter Wärmeträger über den Vorlauf 8 aus dem Wärmetauscher 7 entnommen wird. Um die fühlbare Wärme der Abgase aus der Brennkammer 2 vorteilhaft zu nützen, kann der Vorlauf 8 an einen Sammelraum 19 angeschlossen werden, der das Gehäuse 9 des Wärmetauschers 7 zumindest teilweise umschließt und sich in den Bereich der oberen Umlenkkammer 13 erstreckt, sodass zwischen der Umlenkkammer 13 und dem Sammelraum 19 ein zusätzlicher Wärmeaustausch von den Abgasen auf den Wärmeträger erfolgt. Die Verbindung zwischen dem Gehäuse 9 und dem Sammelraum 19 erfolgt über Durchtrittsöffnungen 20.The flow connection between the flow space 4 within the shell 3 partially enclosing the combustion chamber 2 and the housing 9 of the heat exchanger 7 takes place through passage openings 18, which are provided both in a lower and in an upper region of the flow space 4. Due to this flow connection between the housing 9 of the heat exchanger 7 and the flow space 4 can build a convection flow for the heat transfer between the housing 9 and the flow chamber 4, which also ensures an advantageous heating of the heat carrier, if no heated heat carrier via the flow. 8 is removed from the heat exchanger 7. In order to advantageously use the sensible heat of the exhaust gases from the combustion chamber 2, the flow 8 can be connected to a collecting space 19 which at least partially surrounds the housing 9 of the heat exchanger 7 and extends into the area of the upper deflection chamber 13, so that between the deflection chamber 13 and the collecting space 19, an additional heat exchange from the exhaust gases takes place on the heat transfer medium. The connection between the housing 9 and the collecting space 19 via through openings 20th
