Die Erfindung betrifft ein Heizgerät gemäß dem Oberbegriff des Anspruchs.The invention relates to a heating device according to the preamble of the claim.
Aus der AT-PS 270 135 und der AT-PS 277 520 sind derartige Heizgeräte mit vom hydraulischen Umlaufsystem abzweigend angeordneten Ausdehnungsgefäßen bekannt. Nachteilig dabei sind insbesondere der sperrige Aufbau und die umfangreiche Verrohrung, wodurch Energieverluste durch Abstrahlung unvermeidlich sind.Such heating devices with expansion vessels branching off from the hydraulic circulation system are known from AT-PS 270 135 and AT-PS 277 520. The main disadvantages are the bulky structure and the extensive piping, which means that energy losses due to radiation are unavoidable.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und ein Heizgerät der oben bezeichneten Gattung anzugeben, welches sich durch kompakten und raumsparenden Aufbau sowie durch reduzierte Energieverluste auszeichnet.The invention is based on the object of avoiding these disadvantages and of specifying a heating device of the type described above, which is characterized by a compact and space-saving design and by reduced energy losses.
Erfindungsgemäß gelingt dies mit den kennzeichnenden Merkmalen des Anspruchs. Durch die gemeinsame Wandung der ersten Kammer des Ausdehnungsgefäßes und der Brennkammer wird zum einen erreicht, daß das Gerätevolumen sehr niedrig gehalten werden kann und zum anderen, daß Abstrahlungsverluste über die Brennkammerwandung und über das Ausdehnungsgefäß samt zugehöriger Verroh-According to the invention, this is achieved with the characterizing features of the claim. The common wall of the first chamber of the expansion vessel and the combustion chamber ensures, on the one hand, that the device volume can be kept very low and, on the other hand, that radiation losses via the combustion chamber wall and the expansion vessel together with the associated piping are avoided.
rung minimiert werden. Zusätzlich wird durch die Einwirkung der ersten Kammer in den Umlauf ein entlangströmendes Heizungswassers an der Außenseite der Brennkammer entlangströmende Heizungswasser eine Brennkammerkühlung erreicht. Eine solche Kühlung wirkt sich positiv auf die Emission schädlicher Abgase, insbesondere von thermischem NOx, aus.In addition, the combustion chamber is cooled by the heating water flowing along the outside of the combustion chamber in the circulation of the first chamber. Such cooling has a positive effect on the emission of harmful exhaust gases, particularly thermal NO x .
Die Anmeldung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert.The application is explained in more detail below using an example.
Die einzige Figur zeigt in schematischer Darstellung ein Heizgerät in einer erfindungsgemäßen Ausführung.The single figure shows a schematic representation of a heating device in an embodiment according to the invention.
Dargestellt ist ein Umlaufwasserheizer, bestehend im wesentlichen aus einem Öl- oder Gasbrenner 1, einem Wärmetauscher 2 und einer Abgasführung 3 mit einer Strömungssicherung 4. Der Brenner 1 und der Wärmetauscher 2 sind in einer Brennkammer 5 angeordnet, die von einer Brennkammerwand 6 begrenzt ist. Unmittelbar an die Brennkammerwand 6 angrenzend ist ein Ausdehnungsgefäß 7 angeordnet. Das Ausdehnungsgefäß 7 besteht im wesentlichen aus zwei ersten Kammern 8 und 8' und zwei zweiten Kammern 9 und 9', die jeweils durch Membrane 10 und 10' voneinander getrennt sind. Die beiden ersten Kammern 8 und 81 bilden gleichzeitig den Vorlaufanschluß 11 und den Rücklaufanschluß 12 für den Wärmetauscher 2. Die beiden Kammersysteme können sich über beide Seitenflächen der Brennkammerwand 6 erstrecken. Möglich ist aber auch eine Einbeziehung der Rückseite der Brennkammerwand sowie mindestens eines Teils der Vorderfront der Brennkammerwand 6. Als Puffermittel zur Befüllung der zwei-Shown is a circulating water heater, consisting essentially of an oil or gas burner 1, a heat exchanger 2 and an exhaust gas duct 3 with a flow protection device 4. The burner 1 and the heat exchanger 2 are arranged in a combustion chamber 5, which is delimited by a combustion chamber wall 6. An expansion vessel 7 is arranged directly adjacent to the combustion chamber wall 6. The expansion vessel 7 essentially consists of two first chambers 8 and 8' and two second chambers 9 and 9', which are each separated from one another by membranes 10 and 10'. The two first chambers 8 and 8 1 simultaneously form the flow connection 11 and the return connection 12 for the heat exchanger 2. The two chamber systems can extend over both sides of the combustion chamber wall 6. However, it is also possible to include the rear of the combustion chamber wall and at least part of the front of the combustion chamber wall 6. As a buffer medium for filling the two-
ten Kammern 9 und 9' ist Stickstoff vorgesehen. Die Membranen 10 und 10', die aus einem Gummimaterial bestehen, gleichen durch ihre Elastizität Volumenänderungen des Wärmetauschmediums innerhalb des hydraulischen Systems infolge von Temperaturschwankungen aus. Gleichzeitig wird eine Kühlung der Brennkammerwand 6 erreicht, wodurch die Bildung von umweltschädigenden Verbrennungsprodukten, insbesondere von NOx, reduziert wird. Eine Geräteverkleidung 13 umschließt die äußeren zweiten Kammern 9 und 9' sowie gegebenenfalls auch andere Gerätekomponenten möglichst eng. Dadurch wird ein Entlangströmen von Raumluft an der Brennkammerwand 6 unterbunden. Auch dadurch werden Energieverluste vermieden. Die Form des Ausdehnungsgefäßes 7 ist weitgehendst an die der Brennkammer angepaßt, so daß nur eine geringfügige Verbreiterung des Heizgerätes resultiert. Ein separates, sperriges Ausdehnungsgefäß entfällt jedoch.Nitrogen is provided in the second chambers 9 and 9'. The elasticity of the membranes 10 and 10', which consist of a rubber material, compensates for volume changes in the heat exchange medium within the hydraulic system as a result of temperature fluctuations. At the same time, cooling of the combustion chamber wall 6 is achieved, which reduces the formation of environmentally harmful combustion products, in particular NO x . A device casing 13 encloses the outer second chambers 9 and 9' and, if necessary, other device components as closely as possible. This prevents room air from flowing along the combustion chamber wall 6. This also avoids energy losses. The shape of the expansion vessel 7 is adapted as far as possible to that of the combustion chamber, so that the heater only widens slightly. However, a separate, bulky expansion vessel is not required.
Die Erfindung beschränkt sich nicht auf das vorstehend angegebene Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, die auch bei grundsätzlich anders geartetem Aufbau von den Merkmalen der Erfindung Gebrauch machen.The invention is not limited to the embodiment described above. Rather, a number of variants are conceivable that make use of the features of the invention even with a fundamentally different structure.
