Abstract
Description
Die Erfindung bezieht sich auf eine Heizeinrichtung mit einem in einer einen Doppelmantel aufweisenden, mit einem Rauchgasabzug versehenen Brennkammer angeordneten Brenner und einem Lamellen-Wärmetauscher, wobei der Doppelmantel der Brennkammer einen nach außen gerichteten Flansch aufweist und der Lamellen-Wärmetauscher in einem umlaufenden, kongruent mit der Innenwand beziehungsweise den Innenwänden des Doppelmantels ausgebildeten Mantel gehalten ist, der mit Flanschen versehen ist, mit denen der Mantel mit dem Doppelmantel und dem Rauchgasabzug verbunden ist.The invention relates to a heating device with a burner arranged in a combustion chamber having a double jacket and provided with a flue gas discharge and a lamella heat exchanger, the double jacket of the combustion chamber having an outwardly directed flange and the lamella heat exchanger in a rotating, congruent with the inner wall or the inner walls of the double jacket is held, which is provided with flanges with which the jacket is connected to the double jacket and the flue gas outlet.
Bei solchen Heizeinrichtungen ergibt sich stets das Problem der Anbringung des Wärmetauschers.With such heating devices, there is always the problem of attaching the heat exchanger.
Bei einer bekannten Lösung durchsetzen die Zu- und Ableitungen des Lamellen-Wärmetauschers den Doppelmantel der Brennkammer. Dabei ergeben sich jedoch erhebliche Probleme im Hinblick auf die Beständigkeit der Durchführungen, da sich in diesen Bereichen erhebliche Spannungen aufgrund von größeren Temperaturunterschieden ergeben, die zu Rissen führen können.In a known solution, the feed and discharge lines of the finned heat exchanger enforce the double jacket of the combustion chamber. However, there are considerable problems with regard to the durability of the bushings, since considerable stresses arise in these areas due to larger temperature differences, which can lead to cracks.
Aus der EP-OS 315 577 ist es weiterhin bekannt, eine doppelwandige Brennkammer mit einem umlaufenden Flansch zu versehen, auf dem eine Wärmetauscherhalterung, die ebenfalls einen Flansch aufweist, montiert wird. Die beiden Flansche liegen dabei satt aufeinander und werden in herkömmlicher Weise mittels einer aufwendigen Schweißnaht oder üblicher Befestigungsbolzen miteinander verbunden. Nachteilig hierbei ist vor allem eine verbleibende Restunsicherheit in bezug auf die Dichtigkeit der Verbindung trotz eines erheblichen Montageaufwandes.From EP-OS 315 577 it is also known to provide a double-walled combustion chamber with a circumferential flange on which a heat exchanger bracket, which also has a flange, is mounted. The two flanges lie snugly on top of one another and are connected to one another in a conventional manner by means of an elaborate weld seam or conventional fastening bolts. The main disadvantage here is a remaining residual uncertainty with regard to the tightness of the connection despite considerable installation effort.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Heizeinrichtung der eingangs erwähnten Art vorzuschlagen, die sich durch einen einfachen Aufbau auszeichnet, bei dem sich keine Probleme bei der Halterung des Lamellen-Wärmetauschers ergeben.The aim of the invention is to avoid these disadvantages and to propose a heating device of the type mentioned at the outset, which is distinguished by a simple structure in which there are no problems with the mounting of the fin heat exchanger.
Erfindungsgemäß wird dies dadurch erreicht, daß die Flansche des Mantels mit den Flanschen des Doppelmantels durch Verquetschen von in den äußeren Randbereichen durch Schnitte voneinander getrennten zahnartigen Abschnitten der aneinander anliegenden Flansche verbunden sind, wobei die zahnartigen Abschnitte aus der Trennebene der Flansche ausgebogen sind.According to the invention, this is achieved in that the flanges of the jacket are connected to the flanges of the double jacket by squeezing tooth-like sections of the flanges which are separated from one another by cuts in the outer edge regions, the tooth-like sections being bent out of the parting plane of the flanges.
Auf diese Weise werden Durchführungen durch den Doppelmantel der Brennkammer zur Halterung des Lamellen-Wärmetauschers überflüssig. Die Durchführungen lassen sich im Mantel des Lamellen-Wärmetauschers wesentlich einfacher gestalten und herstellen als im Doppelmantel der Brennkammer, wie dies bei einer bisherigen Lösung vorgesehen war. Außerdem ergibt sich eine sehr einfach herstellbare Verbindung des Doppelmantels mit dem Lamellen-Wärmetauscher, die sich mit geringem fertigungstechnischen Aufwand herstellen läßt.In this way, bushings through the double jacket of the combustion chamber for holding the fin heat exchanger are unnecessary. The bushings can be designed and manufactured much easier in the jacket of the finned heat exchanger than in the double jacket of the combustion chamber, as was the case with a previous solution. In addition, there is a very easy to manufacture connection of the double jacket to the finned heat exchanger, which can be produced with little manufacturing effort.
Dabei kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß die aneinander angrenzenden miteinander verguetschten Abschnitte der Flansche in einander entgegengesetzten Richtungen aus der Trennebene der Flansche ausgebogen sind.According to a further feature of the invention, it can be provided that the mutually adjacent sections of the flanges which are poisoned with one another are bent out of the parting plane of the flanges in opposite directions.
Dadurch ergibt sich eine besonders sichere Verbindung der Brennkammer mit dem den Lamellen-Wärmetauscher haltenden Mantel.This results in a particularly secure connection of the combustion chamber with the jacket holding the finned heat exchanger.
Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß zwischen den Flanschen der Brennkammer und dem Mantel des Lamellen-Wärmetauschers eine Metalldichtung zwischengelegt ist.According to a further feature of the invention it can be provided that a metal seal is interposed between the flanges of the combustion chamber and the jacket of the finned heat exchanger.
Auf diese Weise läßt sich sehr einfach ein hohes Maß an Dichtheit erreichen, wobei die Dichtung selbst sehr beständig ist und den in diesem Bereich herrschenden Temperaturen widersteht.In this way it is very easy to achieve a high degree of tightness, the seal itself being very stable and withstanding the temperatures prevailing in this area.
Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß in der Anlagefläche des Flansches des Rauchgasabzuges eine umlaufende Rille eingearbeitet ist, die zur Aufnahme einer Dichtung dient.According to a further feature of the invention it can be provided that a circumferential groove is used in the contact surface of the flange of the flue gas outlet, which groove is used to receive a seal.
Auf diese Weise ergibt sich eine in konstruktiver Hinsicht sehr einfache Verbindung des Mantels mit dem Rauchgasabzug.In this way, there is a constructionally very simple connection of the jacket to the flue gas outlet.
Die Erfindung wird nun anhand der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the drawing.

Zwischen die Flansche 3 und 10 ist eine metallische Dichtung (nicht dargestellt) zwischengelegt, deren Lebensdauer im wesentlichen auf die Lebensdauer der gesamten Heizeinrichtung ausgelegt ist. Die Verbindung der beiden Flansche 3 und 10 ist dabei betriebsmäßig unlösbar gestaltet. Diese Verbindung erfolgt dabei in der Weise, daß in den Rändern der Flansche 3 und 10 kongruente Schnitte 18 angeordnet sind, die verschiedene Abschnitte 15, 16 voneinander trennen.A metallic seal (not shown) is interposed between the
Die einzelnen Abschnitte 15, 16 der Flansche 3, 10 sind miteinander verguetscht, wobei zumindest einer dieser Abschnitte 15, 16 aus der Trennebene der Flansche 3, 10 ausgebogen ist, wie dies aus der Figur 3 zu ersehen ist. Dabei ist es grundsätzlich auch möglich, die Abschnitte 15, 16 in zueinander entgegengesetzten Richtungen aus der Trennebene der Flansche 3, 10 auszubiegen.The
Bei der Herstellung der Verbindung der Flansche 3 und 10 ist es zweckmäßig, die einzelnen Abschnitte 15 beziehungsweise 16 der Flansche 3, 10 gemeinsam aus der Trennebene der Flansche auszubiegen und im ausgebogenen Zustand miteinander zu verquetschen. Dies kann in einem Arbeitsgang erfolgen.When establishing the connection of the
