Die Neuerung betrifft einen aufrechtstehenden, gasbeheizten Kessel gemäß dem Oberbegriff des Anspruches.The innovation relates to an upright, gas-fired boiler according to the generic term of the claim.
Bei derartigen wassergefüliten Heizkesseln, in deren Wasserraum Bauteile, wie Brennraum und Wärmetauscher hineinragen, besteht die Aufgabe, die wasserseitigen Konturen dieser Einbauten möglichst strömungsgünstig zu gestalten, wobei insbesondere das Abströmen von Dampfblasen nicht behindert werden darf.In the case of such water-filled boilers, in whose water space components such as the combustion chamber and heat exchanger protrude, the task is to design the water-side contours of these components to be as aerodynamic as possible, whereby in particular the outflow of steam bubbles must not be impeded.
Neuerungsgemäß wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruches gelöst.According to the innovation, this problem is solved with the characterizing features of the claim.
Eine vorteilhafte Ausgestaltung geht aus der Figur hervor, die einen aufrechtstehenden, gasbeheizten Kessel mit einem im oberen Bereich angeordneten, von einem topfförmigen Gehäuse 1 begrenzten Brennraum 2 zeigt, in dem ein Sturzbrenner 3 angeordnet ist. Die Brennerabgase durchströmen einen unterhalb des Brennraumes 2 angeordneten Plattenwärmetauscher 4 und gelangen in einen Abgassammeiraum 5, von dem ein Abgasrohr 6 abzweigt, das in einen nicht näher dargestellten Kamin mündet. Der Plattenwärmetauscher 4 wird von zu erwärmendem Wasser durchströmt, wobei das Brennraumgehäuse 1 und der Plattenwärmetauscher 4 in einen Wassermantel 7 eintauchen. Dieses Kesselwasser ist in einen hydraulischen Kreislauf eingebunden. Dazu sind ein in den unteren Bereich des Wassermantels 7 einmündender Rücklauf 8 und ein von dessenAn advantageous embodiment is shown in the figure, which shows an upright, gas-fired boiler with a combustion chamber 2 arranged in the upper area, delimited by a pot-shaped housing 1, in which a downdraft burner 3 is arranged. The burner exhaust gases flow through a plate heat exchanger 4 arranged below the combustion chamber 2 and reach an exhaust gas collection chamber 5, from which an exhaust gas pipe 6 branches off, which opens into a chimney (not shown in detail). Water to be heated flows through the plate heat exchanger 4, with the combustion chamber housing 1 and the plate heat exchanger 4 immersed in a water jacket 7. This boiler water is integrated into a hydraulic circuit. For this purpose, a return 8 opening into the lower area of the water jacket 7 and a
chen. Dieses Kesselwasser ist in einen hydraulischen Kreislauf eingebunden. Dazu sind ein in den unteren Bereich des Wassermantels 7 einmündender Rücklauf 8 und ein von dessen oberen Bereich abzweigender Vorlauf 9 vorgesehen. Vorlauf 9 und Rücklauf 8 sind unter Einschließung eines Wärmeverbrauchers, beispielsweise einer Umlaufwasserheizung, einer Fußbodenheizung oder eines Sekundärwärmetauschers zur Brauchwasserbereitung, miteinander verbunden. Um innerhalb des Kessels eine Zwangsströmung durch die Rippen 10 des Plattenwärmetauschers 4 zu erreichen, kann eine der Mündung des Rücklaufes 8 gegenüberliegende Prallplatte 11 und/oder ein oder mehrere Umlenkplatten 12 innerhalb des Wassermantels 7 vorgesehen sein.This boiler water is integrated into a hydraulic circuit. For this purpose, a return line 8 leading into the lower area of the water jacket 7 and a flow line 9 branching off from its upper area are provided. Flow line 9 and return line 8 are connected to one another, enclosing a heat consumer, for example a circulating water heating system, an underfloor heating system or a secondary heat exchanger for domestic water preparation. In order to achieve a forced flow through the fins 10 of the plate heat exchanger 4 within the boiler, a baffle plate 11 opposite the mouth of the return line 8 and/or one or more deflection plates 12 can be provided within the water jacket 7.
Der Kessel wird bevorzugt nach dem Brennwertprinzip betrieben. Für die Abführung des dann entstehenden Kondensats ist an der tiefsten Stelle des Kessels ein Kondensatablauf 13 angeordnet.The boiler is preferably operated according to the condensing principle. A condensate drain 13 is located at the lowest point of the boiler to drain the condensate that is then produced.
Das Gehäuse 1 des Brennraumes 2 samt Sturzbrenner 3 ist zur Kessellängsachse 14 geneigt in den Kessel eingesetzt. Dabei beträgt der Neigungswinkel zwischen einer Gehäuselängsachse 15 und der Kessellängsachse 14 beispielsweise 45°. Die Schräglage hat den Vorteil, daß der an einer Brennraumtür angeflanschte Sturzbrenner 3 leicht weggeklappt werden kann, so daß sowohl der Brenner 3 a!s auch der an den Boden 16 des topfförmigen Brennraumes 2 angesetzte Plattenwärmetauscher 4 für Wartungs- und Reparaturzwecke zugänglich werden. Das topfförmige Gehäuse 1 besitzt einen größeren Durchmesser als die diagonale Erstreckung der an dessen Boden 16 angesetzten, im wesentlichen rechteckigen Oberseite 17 des Plattenwärmetauschers 4.The housing 1 of the combustion chamber 2 together with the tumbler 3 is inserted into the boiler at an angle to the boiler longitudinal axis 14. The angle of inclination between a housing longitudinal axis 15 and the boiler longitudinal axis 14 is, for example, 45°. The inclined position has the advantage that the tumbler 3 flanged to a combustion chamber door can be easily folded away, so that both the burner 3 and the plate heat exchanger 4 attached to the bottom 16 of the pot-shaped combustion chamber 2 are accessible for maintenance and repair purposes. The pot-shaped housing 1 has a larger diameter than the diagonal extension of the essentially rectangular top 17 of the plate heat exchanger 4 attached to its bottom 16.
Zur Vermeidung strömungsbehindernder und luftblasensammelnder waagerechter Konturen von Kesseleinbauten ist der Boden 16 des Brennraumgehäuses 1 in seinem Randbereich, der die Oberseite 17 des Plattenwärmetauschers 4 überragt, mit einer umlaufenden rotationssymmetrisch zur Gehäuselängsachse 15 verlaufende Abschrägung 18 versehen. Die Abschrägung 18 ist dabei derart getroffen, daß im Einbauzustand der Winkel &agr; derTo avoid horizontal contours of boiler fittings that impede flow and collect air bubbles, the bottom 16 of the combustion chamber housing 1 is provided in its edge area, which projects beyond the top 17 of the plate heat exchanger 4, with a circumferential bevel 18 that runs rotationally symmetrically to the housing longitudinal axis 15. The bevel 18 is designed in such a way that in the installed state the angle α of the
Schräge zur Waagerechten mindestens 10° beträgt. Damit ist der Wassermantel 7 durch die Einbauten an keiner Stelle von einer waagerechten Anströmfläche begrenzt. Dampfblasen können somit nicht an solchen Flächen gesammelt werden, so daß deren zerstörerische Wirkung auf diese Oberflächen entfällt. Je schräger eine angeströmte Fläche zur Strömungsrichtung verläuft, desto besser werden Dampfblasen abtransportiert und können sich auf ihrem Weg nach oben auch nicht aneinander anlagern und somit besonders schädliche Großdampfbiasen bilden. Des weiteren ergibt sich der Vorteil, daß die Wasserströmung in Richtung Vorlauf 9 nicht unnötig durch Einengungen des Wassermantels 7 und resultierende Wirbelbäldung behindert wird. Die Kesselwand kann sehr nahe an die Abschrägung 18 herangerückt werden, so daß das Wasservolumen verringert werden kann.Slope to the horizontal is at least 10°. The water jacket 7 is therefore not limited by a horizontal inflow surface at any point due to the internals. Steam bubbles cannot collect on such surfaces, so that their destructive effect on these surfaces is eliminated. The more inclined a surface is to the direction of flow, the better steam bubbles are removed and cannot attach themselves to one another on their way upwards and thus form particularly harmful large steam bubbles. Another advantage is that the water flow in the direction of the flow 9 is not unnecessarily hindered by constrictions in the water jacket 7 and the resulting vortex formation. The boiler wall can be moved very close to the slope 18, so that the water volume can be reduced.
Die Neuerung beschränkt sich nicht auf das vorstehend angegebene Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen.The innovation is not limited to the embodiment described above. Rather, a number of variants are conceivable which make use of the features of the invention even in a fundamentally different design.
