Abstract
Description
Die Erfindung betrifft einen Wärmeerzeuger für Warmwasserbereitung und Heizungsbetrieb, bestehend aus einem im wesentlichen zylindrischen, vertikalen Behälter mit Kalt- und Warmwasseranschlüssen, mit einem oberen Heizungsvorlauf- und einem unteren Heizungsrücklaufanschluß und mit einer Sturzbrenner-Heizeinrichtung, gebildet aus einer brennerbestückten, den Behälter zentrisch durchgreifenden Wärmeträger- und Heizgasführung.The invention relates to a heat generator for hot water preparation and heating operation, consisting of an essentially cylindrical, vertical container with cold and hot water connections, with an upper heating flow and a lower heating return connection and with a burner heater, formed from a burner-equipped, the container penetrating centrally Heat transfer and heating gas routing.
Wärmeerzeuger dieser Art sind bspw. nach dem DE-U-91 16 438 und nach der DE-A-39 06 715 bekannt. Ganz allgemein werden Wärmeerzeuger dieser Art, sofern diese nicht mit einer elektrischen Heizeinrichtung versehen sind, in der Regel mit Rohrschlangen ausgestattet, die mit dem Vor- und Rücklaufanschluß eines Heizkessels verbunden und in der Nähe des Heizkessels aufgestellt oder unmittelbar mit diesem kombiniert sind. Für Wohnraumheizungen, und zwar insbesondere für vollwärmegedämmte kleinere Eigenheime, weist die Tendenz einerseits in Richtung auf Heizkessel mit kleiner Leistung, andererseits wird man in bezug auf Warmwasserbereitung bzw. Bereithaltung von warmem Brauchwasser immer anspruchsvoller, d.h., es liegen zwei im Grunde entgegengesetzte Tendenzen vor, denen nur mit einem relativ großen apparativen Aufwand Rechnung getragen werden kann, wie dies der Heißwasser-Heizkessel nach der DE-A-39 06 715 zeigt, bei dem, abgesehen von seiner Großvolumigkeit, das Heizungswasser eine entsprechend große dimensionierte Rohrwendel als Durchlauferhitzer durchströmt. Im übrigen soll mit diesem Heißwasser-Heizkessel nicht der erwähnten Tendenz Rechnung getragen, sondern es soll die Verkalkung von Brauchwasserdurchlaufschlangen verhindert werden, was einfach dadurch erreicht werden soll, daß das Heizungswasser, wie erwähnt, durch eine Rohrschlange geleitet wird. Der vorerwähnten Tendenz ist im Vergleich zu diesem Kessel mit einem Wärmeerzeuger nach dem vorerwähnten DE-U-91 16 438 wesentlich besser Rechnung getragen, dies allerdings unter Inkaufnahme einer relativ aufwendigen Konstruktion der Heizgasführung und der Ausbildung einer ausreichend großen Wärmeübertragungsfläche.Heat generators of this type are known, for example, according to DE-U-91 16 438 and DE-A-39 06 715. In general, heat generators of this type, if they are not provided with an electrical heating device, are usually equipped with coils which are connected to the supply and return connections of a boiler and placed near the boiler or combined directly with it. For living room heating, especially for fully heat-insulated smaller homes, the tendency is on the one hand towards boilers with low output, on the other hand, one is becoming more and more demanding in terms of hot water preparation or provision of hot service water, i.e. there are two basically opposite tendencies, which can only be taken into account with a relatively large amount of equipment, as the hot water boiler according to DE-A-39 06 715 shows, in which, apart from its large volume, the heating water flows through a correspondingly large pipe coil as a continuous-flow heater. Incidentally, this hot water boiler does not take into account the tendency mentioned, but rather the calcification of process water flow coils is to be prevented, which is to be achieved simply by passing the heating water through a pipe coil, as mentioned. The above-mentioned tendency is taken into account much better in comparison to this boiler with a heat generator according to the above-mentioned DE-U-91 16 438, however, this has to be accepted with a relatively complex construction of the heating gas duct and the formation of a sufficiently large heat transfer area.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, und zwar ebenfalls unter Beachtung der oben erwähnten an sich entgegengesetzten Tendenz einen kompakten und möglichst kleinvolumigen konstruktiv einfachen Wärmeerzeuger zu schaffen, der primär die Funktion der Warmwasserbereitung und -bereithaltung zu erfüllen vermag, der aber andererseits und damit sekundär auch die Funktion eines Heizkessels übernehmen kann, was mit einfachen Mitteln durch entsprechende Umbildung herkömmlicher Wärmeerzeuger erreichbar sein soll, verbunden mit der Maßgabe, dabei die Heizgasführung mit einer möglichst großen Wärmeübertragungsflä-che auszustatten.The invention is therefore based on the object, also taking into account the above-mentioned opposite tendency to create a compact and as small as possible structurally simple heat generator that can primarily perform the function of hot water preparation and maintenance, but on the other hand and therefore secondary can also take over the function of a boiler, which should be achievable with simple means by appropriate conversion of conventional heat generators, combined with the proviso that the heating gas duct should be provided with the largest possible heat transfer surface.
Diese Aufgabe ist mit einem Wärmeerzeuger der gattungsgemäßen Art nach der Erfindung durch die Kombination der Merkmale 1.1 bis 1.4 des Patentanspruches 1 gelöst.This object is achieved with a heat generator of the generic type according to the invention by combining features 1.1 to 1.4 of
Hierbei ist also gewissermaßen ein Kleinheizkessel (Leistungsgröße bspw. im Bereich von ca. 12 bis 20 KW) in Form einer einfachen Heizgasführung in einem sonst üblichen Behälter mit bspw. nur 100 bis 160 Litern Inhalt für die Warmwasserbereitung integriert, dessen Volumen wesentlich größer ist als der von der Heizgasführung beanspruchte Raum, wobei aber die Heizgasführung und damit die für die Wärmeübertragung wirksame Fläche durch Verwendung eines Rohrregisters wesentlich vergrößert ist. Außerdem ist im Vergleich zum Wärmeerzeuger gemäß vorerwähntem DE-U-91 16 438 das Element zur Rückführung des Vorlaufes im Falle hohen Brauchwasserbedarfs wesentlich vereinfacht und es liegt auch kein einen relativ hohen Widerstand bietender Ringspalt für die Passage der Heizgase mehr vor, da diesen der Gesamtquerschnitt der Einzelrohre des Rohrregisters zur Verfügung steht.In this way, a small boiler (output size, for example, in the range of approx. 12 to 20 KW) is integrated in the form of a simple heating gas flow in an otherwise usual container with, for example, only 100 to 160 liters of content for hot water preparation, the volume of which is significantly larger than the space occupied by the heating gas routing, but the heating gas routing and thus the effective area for heat transfer is significantly increased by using a pipe register. In addition, compared to the heat generator according to the aforementioned DE-U-91 16 438, the element for returning the flow in the case of high demand for hot water is significantly simplified and there is no longer a relatively high resistance annular gap for the passage of the heating gases, since these have the total cross section the individual tubes of the tube register are available.
Die Herstellung der Heizgasführungen und deren Einbau in den Behälter ist dabei denkbar einfach, da diese als vorfertigbare Baueinheiten ebenso einfach in den Behälter integriert werden können, was noch näher erläutert wird.The production of the heating gas guides and their installation in the container is very simple, since they can be integrated into the container just as easily as prefabricated units, which will be explained in more detail.
Durch die erfindungsgemäße Verwendung eines einfachen Rohrregisters kann eine in bezug auf die räumlich relativ kleine Wärmeträgerführung große Wärmetauschfläche untergebracht werden, und dadurch ist auch die vorteilhafte alternative Ausbildungs- und Anordnungsmöglichkeit der Sturzbrennerkammer bedingt, nämlich zum einen in der Wärmeträgerführung selbst und zum anderen oben auf dieser aufgesetzt, wobei letztere insbesondere für den Fall in Frage kommt, bei dem der Behälter relativ klein ist.Through the use of a simple pipe register according to the invention, a heat exchange surface which is large in relation to the spatially relatively small heat transfer duct can be accommodated, and this also results in the advantageous alternative design and arrangement possibility of the lint burner chamber, namely on the one hand in the heat transfer duct itself and on the other on top of it put on, the latter in particular in the case where the container is relatively small.
Der erfindungsgemäße Wärmeerzeuger und dessen vorteilhafte weiteren Ausgestaltungen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The heat generator according to the invention and its advantageous further refinements are explained in more detail below with the aid of exemplary embodiments.

Der Wärmeerzeuger für Warmwasserbereitung und Heizbetrieb besteht grundsätzlich aus einem im wesentlichen zylindrischen, vertikalen Behälter 1 mit Kalt- und Warmwasseranschlüssen 2, 3, mit einem oberen Heizungsvorlauf- und einem unteren Heizungsrücklaufanschluß 4, 5 und mit einer Sturzbrenner-Heizeinrichtung 6, gebildet aus einer brennerbestückten, den Behälter 1 zentrisch durchgreifenden Wärmeträger- und Heizgasführung 7, 8.The heat generator for hot water preparation and heating operation basically consists of an essentially cylindrical,
Für einen solchen Wärmeerzeuger ist nun im Kombination wesentlich:
Zwischen dem Boden 9 der einen ersten Teil der Heizgasführung 8 bildenden Sturzbrennerkammer 10 und dem unteren Verschluß 11 der als glattes Rohr 12 ausgebildeten Wärmeträgerführung 7 ist als zweiter Teil der Heizgasführung 8 ein Rohrregister R aus mehreren, sich vertikal erstreckenden Einzelrohren 13 angeordnet. Je nach Länge des Rohrregisters R ist die Sturzbrennerkammer 10 am oberen Ende des Rohres 12 aufgesetzt (siehe Fig. 2) oder nimmt einen oberen Teil der Länge des Rohres 12 ein (siehe Fig. 1).The following is essential for such a heat generator in combination:
Between the bottom 9 of the
Ferner ist im unteren Teil des Behälters 1 eine mit dem Vorlaufanschluß 4 verbundene, mehrgängige, das Rohr 12 umfassende Leitungswendel 14 angeordnet und diese ist mit ihrem unteren Ende an das Rohr 12 angeschlossen, und schließlich ist unter dem Verschluß 11 des Rohres 12 eine Abgassammelkammer 15 mit Abgasanschluß 16 und Kondensatablaufanschluß 17 angeordnet.Furthermore, in the lower part of the
Bei der Ausführungsform gemäß Fig. 2 ist der am oberen Ende des Rohres 12 aufgesetzte Sturzbrenner-Heizeinrichtungsteil 6' in Form einer doppelwandig wasserführenden, mit dem Innenraum des Rohres 12 in Verbindung stehenden, im wesentlichen halbkugelförmigen Brennkammer 10' ausgebildet. In dieser Brennkammer 10' ist ein entsprechend formangepaßter Flächenbrenner 18 angeordnet und der Vorlaufanschluß 4 ist an höchster Stelle der wasserführenden Brennkammerdoppelwand 19 angeschlossen. Obgleich hierbei die Brennkammer außerhalb der Wasserführung angeordnet ist, geht nichts an Wärmeübertragungsfläche verloren, da die Brennkammer selbst wasserführend ausgebildet ist und, da unmittelbar mit der Wärmeträgerführung 7 im Behälter 1 in Verbindung stehend, bildet deren oberes, wirksamstes und von Brauchwasser freigestelltes Ende, was für den reinen Heizungsbetrieb von besonderem Interesse ist. Vorteilhaft ist bei dieser Ausführungsform das Rohr 12 zur aufgesetzten Brennkammer 10' hin mit einer kegelstumpfförmigen Erweiterung 20 versehen.In the embodiment according to FIG. 2, the lint burner heating device part 6 'attached to the upper end of the
Beim anderen Ausführungsbeispiel nach Fig. 1 ist eine zylindrische Brennkammer 10'' mit darin eingesetztem zylindrischen Flächenbrenner 21 angeordnet. Diese Ausführungsform kommt insbesondere für größere Behälter 1 in Frage, da bei solchen Behältern genügend Raum zur Verfügung steht, um eine entsprechend große Brennkammer und ein entsprechend großes Rohrregister R unterbringen zu können.In the other exemplary embodiment according to FIG. 1, a
Die Verbindungsleitung 23 vom Vorlaufanschluß 6 zur Leitungswendel 14 könnte zwar auch im Behälter 1 verlaufend angeordnet werden, vorteilhafter ist diese Verbindungsleitung 23 außerhalb des Behälters vorgesehen, zumal diese Leitung mit einer Pumpe 22 bestückt ist, die dann läuft, wenn ein hoher Brauchwasserbedarf ansteht.The connecting
Vorteilhafte bauliche Gestaltungen, die für beide Ausführungen, obgleich nur in der einen oder anderen Fig. 1 und 2 dargestellt, angewandt werden können, bestehen darin, daß der Anschluß 24 der Leitungswendel 14 zur Verbindungsleitung 23 seitlich am Boden 1' des Behälters 1 angeordnet ist (siehe Fig. 1).Advantageous structural designs that can be used for both versions, although only shown in one or the other FIGS. 1 and 2, consist in the fact that the
Ferner durchgreift das Rohr 12 mit seinem unteren Ende den Boden 1' des Behälters 1, und der Rücklaufanschluß 5 ist an diesem herausragenden Ende angeordnet (Fig. 2). Schließlich ist gemaß Fig. 1 vorgesehen, daß der Rücklaufanschluß 5 die Abgassammelkammer 15 durchgreift und am Verschluß 11 des Rohres 12 angeordnet ist.Furthermore, the lower end of the
