Description

Die Erfindung betrifft einen Heizkessel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a heating boiler according to the preamble of patent claim 1.

Ein Heizkessel der eingangs genannten Art ist nach der EP 1 562 006 A1 bekannt. Dieser besteht aus einem eine Brennkammer umschließenden Gehäuse mit einem Öffnungsbereich, der mit einem Öffnungsverschluss verschließbar ausgebildet ist, wobei der Öffnungsverschluss aus einem ersten, ringförmigen, am Gehäuse befestigbaren Teil und einem zweiten, einen Brennerkopf für wahlweise flüssige oder gasförmige Brennstoffe aufnehmenden, deckelartigen Teil gebildet ist.A boiler of the type mentioned is according to EP 1 562 006 A1 known. This consists of a combustion chamber enclosing housing with an opening portion which is formed closable with an opening closure, wherein the opening closure of a first, annular, attachable to the housing part and a second, a burner head for selectively liquid or gaseous fuels receiving, lid-like part formed is.

Wie auch der noch zu erläuternde erfindungsgemäße Heizkessel besteht der Heizkessel nach der EP 1 562 006 A1 insbesondere aus einem im wesentlichen zylinderförmigen Mantelgehäuse, in das ein schraubenförmig gewickelter Wärmetauscher (so genannter Wendelspaltwärmetauscher) eingesetzt ist, wobei im Zentrum des Wärmetauschers eine Brennkammer und zwischen dem Wärmetauscher und der Gehäusewand eine Abgassammelkammer mit Abgasabfuhranschluss definiert sind, d. h. das in der Brennkammer durch die Verbrennung entstehende Abgas strömt durch genau definierte Strömungsspalte des Wärmetauschers in die Abgassammelkammer und von dort zu einem entsprechenden Abgasanschluss. Wie zum Beispiel aus Figur 2 der EP 1 562 006 A1 ersichtlich, weist der Wärmetauscher dabei einen Zu- und einen Abfuhranschluss für ein Wärmeträgermedium (typischerweise Heizkreiswasser) auf, wobei diese Anschlüsse durch entsprechende Durchgriffsöffnungen an den stirnseitigen Deckelelementen des Mantelgehäuses geführt sind.Like the still to be explained boiler according to the invention, the boiler is after the EP 1 562 006 A1 in particular from a substantially cylindrical jacket housing, in which a helically coiled heat exchanger (so-called Wendelspaltwärmetauscher) is used, wherein in the center of the heat exchanger, a combustion chamber and between the heat exchanger and the housing wall an exhaust gas collecting chamber are defined with Abgasabfuhranschluss, ie that in the combustion chamber through the Combustion exhaust gas flows through precisely defined flow gaps of the heat exchanger in the exhaust gas collection chamber and from there to a corresponding exhaust port. Like, for example FIG. 2 of the EP 1 562 006 A1 it can be seen, the heat exchanger in this case has an inlet and a discharge connection for a heat transfer medium (typically heating circuit water), wherein these connections are guided through corresponding through openings on the front-side cover elements of the jacket housing.

Auf der dem Brennerkopf gegenüberliegenden Seite des Gehäuses ist dieses Deckelelement einteilig ausgebildet und gewissermaßen einfach in den Zylindermantel eingeschoben. Brennkopfseitig besteht der Öffnungsverschluss aus dem oben bereits erwähnten, ersten ringförmigen Teil, der bei der Lösung nach der EP 1 562 006 A1 bei der Montage des Kessels zunächst als Einzelbauteil in den Zylindermantel eingeschoben und an diesem befestigt wird. Der dann noch nicht verschlossene, größere Teil des Öffnungsbereichs wird anschließend mit einem zweiten Teil, dem eigentlichen Deckel verschlossen. An diesem Deckel ist der Brennerkopf, aber zum Beispiel auch (was allerdings in der EP 1 562 006 A1 nicht explizit dargestellt ist) das pneumatisch mit dem Brennkopf verbundene Gebläse befestigt.On the burner head opposite side of the housing, this lid member is integrally formed and, so to speak, simply inserted into the cylinder jacket. Brennkopfseitig consists of the opening closure of the above-mentioned, the first annular part, which in the solution after the EP 1 562 006 A1 initially inserted as a single component in the cylinder jacket and attached to this during assembly of the boiler. The then not yet closed, larger part of the opening area is then closed with a second part, the actual lid. On this cover is the burner head, but for example also (which, however, in the EP 1 562 006 A1 not explicitly shown) the pneumatically connected to the combustion head fan attached.

Der Erfindung liegt die Aufgabe zugrunde, einen Heizkessel der eingangs genannten Art insbesondere hinsichtlich seiner Servicefreundlichkeit bei der Wartung zu verbessern.The invention has the object to improve a boiler of the type mentioned in particular with regard to its ease of servicing during maintenance.

Diese Aufgabe ist mit einem Heizkessel der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a boiler of the type mentioned by the features listed in the characterizing part of patent claim 1.

Nach der Erfindung ist also vorgesehen, dass beide Teile des Öffnungsverschlusses als Funktionseinheit gemeinsam am Gehäuse montierbar ausgebildet sind, wobei am ersten, ringförmigen Teil des Öffnungsverschlusses ein Komponententräger für das Gebläse angeordnet ist.According to the invention, it is thus provided that both parts of the opening closure are designed as a functional unit mounted together on the housing, wherein the first, annular part of the opening closure, a component carrier for the fan is arranged.

Mit anderen Worten ausgedrückt, wird erfindungsgemäß nicht mehr zunächst nur der erste, ringförmige Teil am Gehäuse und danach erst der zweite am ersten Teil befestigt, sondern beide Teile werden gemeinsam in einem Arbeitsschritt als Funktions- bzw. Montageeinheit am Gehäuse montiert. Zusammen mit der Maßgabe, dass am ersten Teil auch noch (mindestens) ein Komponententräger für das Gebläse (und gegebenenfalls weitere Komponenten wie eine Ölpumpe oder dergleichen) vorgesehen ist, ergibt sich daraus insgesamt erstmals die Möglichkeit, am zweiten Teil insbesondere nur den Brennerkopf anzuordnen, was bei Wartungsarbeiten den erheblichen Vorteil hat, dass nur der zweite, auf diese Weise deutlich leichtere Teil des Öffnungsverschlusses demontiert und bewegt werden muss. Bei der Lösung nach der EP 1 562 006 A1 sind dagegen am zweiten Teil des Öffnungsverschlusses alle weiteren Komponenten wie Gebläse, Ölpumpe etc. befestigt, d. h. in diesem Fall ist dieser zweite Teil deutlich schwerer und dementsprechend unhandlicher (siehe auch Figur 6 und 7).In other words, according to the invention, it is no longer initially only the first, annular part on the housing and then the second attached to the first part, but both parts are mounted together in one step as a functional or mounting unit on the housing. Together with the proviso that on the first part also (at least) a component carrier for the fan (and optionally other components such as an oil pump or the like) is provided, this results in total for the first time the possibility to arrange on the second part in particular only the burner head, which during maintenance the considerable Advantage is that only the second, in this way much lighter part of the opening closure must be dismantled and moved. In the solution after the EP 1 562 006 A1 On the other hand, on the second part of the opening closure, all other components such as fan, oil pump, etc. are attached, ie in this case, this second part is significantly heavier and accordingly more cumbersome (see also FIGS. 6 and 7 ).

Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments emerge from the dependent claims.

Der Vollständigkeit halber wird noch auf die DE 101 14 490 C1 hingewiesen.The sake of completeness is still on the DE 101 14 490 C1 pointed.

Der erfindungsgemäße Heizkessel einschließlich seiner vorteilhaften Weiterbildungen gemäß den abhängigen Patentansprüchen wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The boiler according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

Der erfindungsgemäße Heizkessel, der in Figur 1 im Prinzip vollständig dargestellt ist (allerdings ohne Umschließungsgehäuse, Leitungen etc.) besteht zunächst einmal in an sich bekannter Weise aus einem eine Brennkammer 1 umschließenden, zylinderförmigen Gehäuse 2 mit einem stirnseitigen Öffnungsbereich 3, der mit einem Öffnungsverschluss 4 verschließbar ausgebildet ist. Dabei ist der Öffnungsverschluss 4 aus einem ersten, ringförmigen, am Gehäuse 2 befestigbaren Teil 5 und einem zweiten, einen Brennerkopf 6 für wahlweise flüssige oder gasförmige Brennstoffe aufnehmenden, deckelartigen Teil 7 gebildet. Der genannte Brennerkopf 6 ist pneumatisch mit einem am Öffnungsverschluss 4 angeordneten Gebläse 8 verbunden.The boiler according to the invention, the in FIG. 1 is shown in principle completely (but without enclosing housing, pipes, etc.) consists first of all in a conventional manner from a combustion chamber 1 enclosing, cylindrical housing 2 with an end-side opening portion 3, which is formed closable with an opening closure 4. In this case, the opening closure 4 of a first, annular, attachable to the housing part 2 and a second, a burner head 6 for selectively liquid or gaseous fuels receiving, cover-like part 7 is formed. Said burner head 6 is pneumatically connected to a blower 8 arranged at the opening closure 4.

Mit Verweis auf Figur 2 ist im Gehäuse 2 ein die Brennkammer 1 umschließender, schraubenförmig gewickelter Wärmetauscher 15 und zwischen diesem und dem Gehäuse 2 eine Abgassammelkammer 16 angeordnet. Der erste Teil 5 des Öffnungsverschlusses 4 weist eine Durchgriffsöffnung 18 für einen Anschlussstutzen 19 des Wärmetauschers 15 auf. Außerdem ist der erste Teil 5 des Öffnungsverschlusses 4 in den Öffnungsbereich 3 des Gehäuses 2 einsteckbar ausgebildet (vergleiche hierzu insbesondere Figur 5), wobei besonders bevorzugt der erste und der zweite Teil 5, 7 des Öffnungsverschlusses 4 aus Aluminium, insbesondere Aluminiumdruckguss, gebildet sind. Das Aluminium ist dabei insbesondere für Anwendungen mit Heizölverbrennung mit einer entsprechenden Beschichtung oder Abschirmung gegen korrosiven Säureangriff versehen.With reference to FIG. 2 is in the housing 2 a combustion chamber 1 enclosing, helically wound heat exchanger 15 and disposed between the latter and the housing 2, an exhaust gas collection chamber 16. The first part 5 of the opening closure 4 has a through-opening 18 for a connecting piece 19 of the heat exchanger 15. In addition, the first part 5 of the opening closure 4 in the opening portion 3 of the housing 2 is designed to be inserted (compare in particular FIG. 5 ), wherein particularly preferably the first and the second part 5, 7 of the opening closure 4 made of aluminum, in particular die-cast aluminum, are formed. The aluminum is there especially for fuel oil combustion applications with a suitable coating or shield against corrosive acid attack.

Wesentlich für den erfindungsgemäßen Heizkessel ist nun, dass beide Teile 5, 7 des Öffnungsverschlusses 4 als Funktions- bzw. Montageeinheit gemeinsam am Gehäuse 2 montierbar ausgebildet sind, wobei am ersten, ringförmigen Teil 5 des Öffnungsverschlusses 4 ein Komponententräger 9 für das Gebläse 8 angeordnet ist.Essential for the boiler according to the invention is now that both parts 5, 7 of the opening closure 4 as a function or assembly unit are mounted together mounted on the housing 2, wherein the first, annular part 5 of the opening closure 4, a component carrier 9 is arranged for the fan 8 ,

Der Vorteil der Erfindung wird besonders deutlich, wenn man Figur 3 und Figur 6 bzw. 7 miteinander vergleicht: Figur 3 zeigt den leicht handlebaren zweiten Teil 7 des Öffnungsverschlusses 4. In den Figuren 6 und 7 ist die vergleichbare Baugruppe dargestellt, bei der aber mangels eines entsprechenden Komponententrägers am ersten Teil 5 des Öffnungsverschlusses 4 alle Komponenten am zweiten Teil 7 des Öffnungsverschlusses 4 befestigt sein müssen und diesen entsprechend schwer und unhandlich machen.The advantage of the invention becomes particularly clear when one FIG. 3 and FIG. 6 or 7 compared: FIG. 3 shows the easily negotiable second part 7 of the opening closure 4. In the FIGS. 6 and 7 the comparable assembly is shown, but in the absence of a corresponding component carrier on the first part 5 of the opening closure 4, all components on the second part 7 of the opening closure 4 must be attached and make them accordingly heavy and unwieldy.

Wie sich insbesondere aus Figur 2 deutlich ergibt, ist weiterhin vorgesehen, dass der Komponententräger 9 in einer Erstreckungsebene des Öffnungsverschlusses 4 über das Gehäuse 2 hinausragend angeordnet und mindestens gebläseseitig als ebene Platte ausgebildet ist. Konkret ist der Komponententräger 9 als zum Beispiel L-förmiger, mit seinem kurzen Schenkel am ersten Teil 5 des Öffnungsverschlusses 4 befestigter und ebenfalls aus Aluminium bestehender Träger ausgebildet.As can be seen in particular FIG. 2 clearly shows, is further provided that the component carrier 9 is arranged protruding in an extension plane of the opening closure 4 on the housing 2 and at least on the blower side is formed as a flat plate. Specifically, the component carrier 9 is formed as, for example, L-shaped, with its short leg on the first part 5 of the opening closure 4 and also made of aluminum existing carrier.

Bezüglich der Anbindung des Gebläses 8 hat es sich als besonders vorteilhaft erwiesen, wenn der Komponententräger 9 eine Durchgangsöffnung 10 aufweist, an die sich einerseits das peripher zum Gehäuse 2 angeordnete Gebläse 8 und andererseits ein mit dem Brennerkopf 6 verbundener Luftführungskanal 11 anschließt, wobei der Luftführungskanal 11 am deckelartigen Teil 7 befestigt ist und am Komponententräger 9 verbindungsmittelfrei anliegt, was ein leichtes Abnehmen des zweiten Teils 7 des Öffnungsverschlusses 4 ermöglicht, wobei dann aber der Übergangsbereich vom Gebläse 8 über den Komponententräger 9 zum Luftführungskanal 11 mit entsprechenden Dichtmitteln abgedichtet ausgebildet ist.With regard to the connection of the blower 8, it has proved to be particularly advantageous if the component carrier 9 has a passage opening 10, to which on the one hand the Fan arranged peripherally to the housing 2 8 and on the other hand connected to the burner head 6 air duct 11 connects, wherein the air duct 11 is attached to the lid-like part 7 and the component carrier 9 is applied without a connection, which allows easy removal of the second part 7 of the opening closure 4, wherein but then the transition region from the fan 8 via the component carrier 9 to the air duct 11 is formed sealed with corresponding sealing means.

Um weiterhin auch bei Ölbrennern die Ölpumpe nicht am zweiten Teil 7 des Öffnungsverschlusses 4 anordnen zu müssen, ist am ersten Teil 5 des Öffnungsverschlusses 4 mindestens ein zweiter Komponententräger 13 (baulich dem ersten entsprechend), und zwar insbesondere zur Aufnahme einer Ölpumpe 14, angeordnet, wobei die beiden (oder mehr) Komponententräger 9, 13 gewissermaßen in baulich günstiger Weise über den Umfang des Gehäuses 2 verteilt angeordnet sind.In order, furthermore, not to have to arrange the oil pump on the second part 7 of the opening closure 4 in the case of oil burners, at least a second component carrier 13 (structurally corresponding to the first one) is arranged on the first part 5 of the opening closure 4, specifically for receiving an oil pump 14, wherein the two (or more) component carrier 9, 13 are distributed in a structurally favorable manner over the circumference of the housing 2, as it were.

Um den Heizkessel bei Bedarf gut reinigen zu können (also der oben genannte Wartungsfall) ist vorgesehen, dass ein gehäuseabgewandter Rand 17 des ersten Teils 5 des Öffnungsverschlusses 4 etwa zur inneren Oberfläche des Wärmetauschers 15 fluchtet. Etwas anders ausgedrückt, ist vorgesehen, dass die Brennkammer 1 und der zweite Teil 7 des Öffnungsverschlusses 4 einen etwa gleichen Durchmesser (zum Beispiel zwischen 20 cm und 50 cm) aufweisen.In order to clean the boiler well when needed (ie the above maintenance case) is provided that a housing facing away from the edge 17 of the first part 5 of the opening closure 4 is approximately aligned with the inner surface of the heat exchanger 15. In other words, it is provided that the combustion chamber 1 and the second part 7 of the opening closure 4 have an approximately equal diameter (for example between 20 cm and 50 cm).

Um den Öffnungsbereich 3 ordnungsgemäß abzudichten, ist zwischen dem ersten und dem zweiten Teil 5, 7 eine abgedichtet ausgebildete Nut- und Federverbindung vorgesehen (siehe hierzu Figur 4), wobei der zweite Teil 7 des Öffnungsverschlusses 4 am ersten Teil 5 anschraubbar ausgebildet ist.In order to properly seal the opening area 3, a sealed groove and tongue connection is provided between the first and the second part 5, 7 (cf. FIG. 4 ), wherein the second part 7 of the opening closure 4 on the first part 5 is screwed.

Zur wärmetechnischen Isolation ist weiterhin am zweiten Teil 7 des Öffnungsverschlusses 4 brennkammerseitig ein Wärmedämmelement 20 (siehe hierzu zum Beispiel die DE 196 27 961 A1 ) angeordnet.For thermal insulation is still on the second part 7 of the opening closure 4 combustion chamber side, a thermal insulation element 20 (see, for example, the DE 196 27 961 A1 ) arranged.

Schließlich ist am zweiten Teil 7 des Öffnungsverschlusses 4 zum Beispiel ein Zündtransformator 21 und am Luftführungskanal 11 zum Beispiel ein Luftdruckwächter 12 angeordnet.Finally, on the second part 7 of the opening closure 4, for example, an ignition transformer 21 and the air duct 11, for example, an air pressure switch 12 is arranged.
