Vorrichtung zur Kühlung eines BrennersDevice for cooling a burner
Die Erfindung betrifft eine Vorrichtung zur Kühlung eines den Wärmetauschers eines Umlaufwasserheizers oder Kessels beheizen= den Bifenners mittels zumindest eines sich Über dessen Flämmen1=3 bereich erstreckenden, wasserführenden Kühlrohres* Aufgabe der Erfindung ist es, beim Betrieb eines solchen Bren« nere durch eine wirksame und energiesparende Kühlung des Flam» inenbeceicnes der thermisch bedingten Emission von NO vorzu« beugen, ohne jedoch anderseits eine Unterkühlung des Flammen** bereiches herbeizuführen, die eine erhöhte CO-Emission zur Folge hätte. The invention relates to a device for cooling a burner heating the heat exchanger of a circulating water heater or boiler by means of at least one water-carrying cooling pipe extending over its flame area. The object of the invention is to prevent the thermally induced emission of NO during operation of such a burner by effective and energy-saving cooling of the flame area, without, however, causing supercooling of the flame area, which would result in increased CO emissions.
Erfindungsgemäß erstreckt sich zur Lösung dieser Aufgabe bei oinem Brenner der eingangs bezeichneten Gattung ein aufzu* heizendes Wasser führendes Rohr mit zumindest einem der Kühlung dienenden Rohrstrang von einem dieses Wasser führenden Rücklauf des Umlaufwasserheizers oder eines Kessels ausgehend Über den Flammenbereich des Brenners schräg aufwärtsverlaufend zu dem an den Vorlauf dieses Umlaufwasserheizers oder Kessels ange» schlossenen Wärmetauscher.According to the invention, to solve this problem, in a burner of the type described at the outset, a pipe carrying water to be heated with at least one pipe strand serving for cooling extends from a return line carrying this water of the circulating water heater or a boiler, running diagonally upwards over the flame area of the burner to the heat exchanger connected to the flow line of this circulating water heater or boiler.
Auf diese Weise ist der als Kühlrohr wirksame Rohrstrang, vorteilhaft und energiesparend in den Umlauf des Wasserhei« zers einbesogen. In this way, the pipe string, which acts as a cooling pipe, is advantageously and energy-savingly integrated into the circulation of the water heater .
Der Wärmetauscher selbst kann nach der bevorzugten Ausführungen form der Erfindung aus einem gegebenenfalls mit Rippen bestück= ten, oberhalb des schräg aufwärts verlaufenden Kühlrohrstranges im wesentlichen horizontal durch die Abgasführung des Brenners verlaufenden Rohrstrang desselben Rohres bestehen.According to the preferred embodiment of the invention, the heat exchanger itself can consist of a pipe string of the same pipe, optionally equipped with fins, which runs above the inclined upward cooling pipe string essentially horizontally through the exhaust gas duct of the burner.

AUch der schräg aufwärts verlaufende Kühirohrstrang kann mit den Wärmetäusch begünstigenden Rippen bestückt sein, aller=5 dings mit zur Abgasführung des Brenners parallel verlaufenden, cilso im wesentlichen lotrecht angeordneten, demnach schräg zur Achse des schrägen Kühlrohretranges verlaufenden Rippen« The inclined upward cooling pipe string can also be equipped with fins that promote heat exchange, but with fins that run parallel to the exhaust gas duct of the burner, i.e. are arranged essentially vertically, and therefore run obliquely to the axis of the inclined cooling pipe string.
Die einzige Zeichnungsfigur stellt einen Brenner mit einer erfindungsgemäßen Vorrichtung beispielsweise in einem schemati» sehen Vertikalschnitt dar.The single drawing figure shows a burner with a device according to the invention, for example in a schematic vertical section.
Dieser Brenner umfaßt innerhalb seines eine Abgasführung 12 um=» schließenden Gehäuses 11 zumindest ein Brennerrohr, das stirn» seitig Über ein Mischrohr 2 mit einem Brennstoff-Luft-Gemisch versorgt wird und an seiner Oberseite Gemischaustrittsöffnungen aufweist, an denen sich nach der Zündung in einem Flammenbereich 3 Brennerflammen ausbilden.This burner comprises, within its housing 11, which encloses an exhaust gas duct 12, at least one burner tube, which is supplied with a fuel-air mixture on the front side via a mixing tube 2 and has mixture outlet openings on its upper side, at which burner flames form in a flame region 3 after ignition.
Zur Kühlung dieses Flammenbereiches 3 und zur damit verknüpften Minderung der NO -Emission ist dem Brennerrohr 1 zumindest ein sich über den Flammenbereich 3 erstreckender, einen Abschnitt ' des Rohres 13 bildender Kühlrohrstrang 4 zugeordnet, der in der mit dem Pfeil 5 bezeichneten Strömungsrichtung des Hei= zungsumlaufes unter einem Winkel oL zur Waagrechten schräg auf» wärts verläuft. Dieser schrägverlaufende Kühlrohrstrang 4 setzt sich in dem dem Wärmetauscher 6 des Wasserheizers züge» hörigen, gleichfalls einen Abschnitt des Rohres 13 bildenden horizontal verlaufenden Rohrstrang fort, der in den zum Vor= lauf des Heizungsumlaufes führenden Sammler 7 mündet, der mehreren parallel zueinander in einer Schar angeordneten Kühl= rohrsträngen 4 gemeinsam sein kann. Der Rücklauf des im Hei= zungsumlauf abgekühlten Wassers erfolgt über den Rücklaufverteiler To cool this flame area 3 and to reduce the associated NO emissions, the burner tube 1 is assigned at least one cooling pipe string 4 which extends over the flame area 3 and forms a section of the tube 13 and runs diagonally upwards at an angle oL to the horizontal in the flow direction of the heating circuit indicated by the arrow 5. This diagonally running cooling pipe string 4 continues in the horizontally running pipe string associated with the heat exchanger 6 of the water heater , which also forms a section of the tube 13 and opens into the collector 7 leading to the flow of the heating circuit, which can be common to several cooling pipe strings 4 arranged parallel to one another in a group. The return of the water cooled in the heating circuit takes place via the return distributor.

Solche Wärmetauscher zeichnen sich durch eine geringe Bauhöhe aus, so daß mit ihnen sehr kompakte Wasserheizer oder Kessel hergestellt! werden können.Such heat exchangers are characterized by a low installation height, so that very compact water heaters or boilers can be manufactured with them!
Selbstverständlich sind die Einzelheiten des Erfindungsgegen« Standes mannigfach abwandelbar. So können etwa die Rippen der Rohrstränge 4 und 6 durch Nadeln od.dgl. der Wärmeübertragung dienende Fortsätze gleichwertig ersetzt sein. Of course, the details of the subject matter of the invention can be modified in many ways. For example, the ribs of the pipe sections 4 and 6 can be replaced by needles or similar extensions serving to transfer heat .
