Definitions
- the invention relates to a heating boiler according to the preamble of patent claim 1.
- a boiler of the type mentioned is from the document DE 44 15 028 A1 known.
- This boiler consists of a boiler room through which a heating circuit medium flows, which has a return connection for supplying the heating circuit medium to the boiler room and both a flow connection and an additional flow connection for removing the heating circuit medium from the boiler room, with the return flow connection in an opening arranged in the boiler room and an opening to the boiler room having flow guidance is designed to open out, with a device for adjusting a flow rate of heating circuit medium flowing through the flow connection and/or via the opening through the additional flow connection is provided, with the flow connection and the additional flow connection being designed to open out into a common main flow connection.
- the object of the invention is to improve a heating boiler of the type mentioned at the outset.
- one should effective and cost-effective construction for controlling the (total) flow temperature independently of the boiler temperature can be created.
- the flow guide is tubular and the heating circuit medium, apart from the heating circuit medium flowing out at the opening, is insulated from the heating circuit medium and leads into the boiler room and opens out into the flow connection.
- the heating boiler according to the invention is characterized by the fact that with the help of this special flow guidance construction it is possible in a simple manner to guide the relatively cool heating circuit medium arriving at the return connection from the heating circuit equipped with a heating circuit pump through the boiler room to the flow connection with practically no thermal influence . Since hotter heating circuit medium coming directly from the boiler room is also available via the additional flow connection, the temperature of the heating circuit medium at a common outlet or at a central main flow connection of the boiler, in the flow connection on the one hand and the additional flow connection on the other hand can be set exactly. The tighter the flow connection is closed, the more heating circuit medium will flow through the opening mentioned above brought into the boiler room and the hotter the heating circuit medium will then be at the common outlet mentioned above.
- the requirement that an opening is provided on the flow guide means that at least one opening is provided. It is particularly preferred, however, to provide a plurality of openings through which comparatively cold heating circuit medium coming from the return connection can flow into the boiler room. Whether a lot or little heating circuit medium flows from the return connection into the boiler room is, as already explained, determined by the device.
- the heating boiler according to the invention which - which is not shown separately - is preferably designed as a biomass boiler, in particular a pellet boiler, or also as a condensing boiler, consists initially in a known manner of a boiler room 1 through which a heating circuit medium (in particular water) flows, the one Return connection 2 for supplying the heating circuit medium to the boiler room 1 and both a flow connection 3 and an additional flow connection 4 for removing the heating circuit medium from the boiler room 1, the return connection 2 opening into a flow guide 5 arranged in the boiler room 1 and having an opening 5.1 to the boiler room 1 is trained.
- a heating circuit medium in particular water
- the boiler room 1 is designed to at least partially enclose a combustion chamber 8 .
- the combustion chamber 8 is completely surrounded by the boiler chamber 1, with the boiler chamber 1 having at least one outer wall 1.1 that delimits a volume that is sealed off in a fluid-tight manner.
- the flow guide 5 is designed to open out into the flow connection 3 (i.e. - apart from the opening 5.1 - connected in a fluid-tight manner) and a device 6 for setting a flow rate that optionally flows through the flow connection 3 and/or via the opening 5.1 through the additional flow connection 4 Flow amount of heating medium is provided.
- the flow guide 5 it is particularly preferable for the flow guide 5 to have not just one but several openings 5.1 (e.g. in the form of round holes) so that the heating circuit medium coming from the return connection 2 can flow into the boiler room 1 as evenly as possible.
- the openings 5.1 are furthermore particularly preferably all formed on the same side of the flow guide 5.
- the opening 5.1 or openings 5.1 are in the direction of the outer wall 1.1 of the boiler room 1, on the preferably also the flow connection 3 and the additional flow connection 3 are arranged pointing.
- the flow guide 5 is tubular 15 in order to guide the heating circuit medium isolated from the heating circuit medium in the boiler room 1 apart from the outflowing heating circuit medium at the above-mentioned openings 5.1.
- the flow guide 5 is optionally arranged adjacent and predominantly along an outer wall 1.1 of the boiler chamber 1 and/or between the outer wall 1.1 and the combustion chamber 8.
- the flow guide 5 is designed in one piece between the return connection 2 and the flow connection 3, ie heating circuit medium can only leave the flow guide 5 via the opening 5.1 or openings 5.1 or via the flow connection 3.
- the flow connection 3 and the additional flow connection 4 are designed to open out into a common main flow connection 7 , which is arranged here outside of the boiler room 1 .
- the flow connection 3 and the additional flow connection 4 are arranged at the same height on the boiler room 1 .
- These two connections 3, 4, but preferably also the device 6 for setting the respective amount of heating circuit medium, are then positioned completely within the boiler room 1.
- hot heating circuit medium is thus mixed in via the additional flow connection 4 according to the setting of the device 6 at the main flow connection 7, with the heating circuit medium being fed into the boiler room 1 via the opening 5.1 or openings 5.1 and heated there.
- the openings 5.1 are arranged at a distance from the additional flow connection 4 in order to avoid a hydraulic short circuit.
- this is optionally designed as a valve that is preferably continuously adjustable with regard to its flow rate and/or can be actuated by means of a heating control.
- the device 6 is optionally arranged on the flow connection 3 and/or between the flow guide 5 and the main flow connection 7 .
- the boiler according to the invention works as follows: The starting point for the following explanation is that the device 6 or the valve is closed, ie an outflow of heating circuit medium via the flow connection 3 to the main flow connection 7 is completely prevented. As a result, the heating circuit medium returned to the boiler via the return connection 2 must flow into the boiler room 1 via the openings 5.1. This in turn means that the heating circuit medium introduced into the boiler room 1 is heated by the heat-emitting combustion chamber 8 . In addition, for reasons of continuity, since the flow connection 3 is closed, the amount of heating circuit medium that was fed to the boiler room 1 via the return flow connection 2 must be discharged via the additional flow connection 4, which also means that the heating circuit medium arriving at the main flow connection 7 is maximal is heated.
- the heating circuit medium can enter the boiler room 1 via the openings 5.1, provided that the flow resistance of the flow guide 5 between the return connection 2 and the flow connection 3 is sufficiently low to stream. Rather, it can flow practically unhindered from the return connection 2 via the flow guide 5 to the flow connection 3 and from there to the main flow connection 7 connected to a heating circuit with a heating circuit pump (not shown separately because it is generally known). Since the heating circuit medium thereby from the flow guide 5 is shielded from the boiler room 1, it is heated only slightly, if at all, i.e. the temperature of the heating circuit medium at the main flow connection 7 roughly corresponds to the temperature of the heating circuit medium at the return flow connection 2.

Description
Die Erfindung betrifft einen Heizkessel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a heating boiler according to the preamble of
Ein Heizkessel der eingangs genannten Art ist aus dem Dokument
Darüber hinaus ist aus dem Dokument
Verwiesen wird auch noch auf das Dokument
Der Erfindung liegt die Aufgabe zugrunde, einen Heizkessel der eingangs genannten Art zu verbessern. Insbesondere soll eine effektive und kostengünstige Konstruktion zur Regelung der (Gesamt-) Vorlauftemperatur unabhängig von der Kesseltemperatur geschaffen werden.The object of the invention is to improve a heating boiler of the type mentioned at the outset. In particular, one should effective and cost-effective construction for controlling the (total) flow temperature independently of the boiler temperature can be created.
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
Nach der Erfindung ist also vorgesehen, dass die Strömungsführung rohrförmig und das Heizkreismedium abgesehen von an der Öffnung abströmendem Heizkreismedium isoliert vom Heizkreismedium im Kesselraum führend und in den Vorlaufanschluss ausmündend ausgebildet ist.According to the invention, it is therefore provided that the flow guide is tubular and the heating circuit medium, apart from the heating circuit medium flowing out at the opening, is insulated from the heating circuit medium and leads into the boiler room and opens out into the flow connection.
Mit anderen Worten zeichnet sich der erfindungsgemäße Heizkessel somit dadurch aus, dass es mit Hilfe dieser speziellen Strömungsführungskonstruktion auf einfache Weise möglich ist, das aus dem mit einer Heizkreispumpe versehenen Heizkreis am Rücklaufanschluss ankommende, relativ kühle Heizkreismedium thermisch praktisch unbeeinflusst durch den Kesselraum zum Vorlaufanschluss zu führen. Da weiterhin über den Zusatzvorlaufanschluss heißeres, direkt aus dem Kesselraum kommendes Heizkreismedium zur Verfügung steht, kann durch gezieltes Festlegen des Mengenverhältnisses des vom Vorlaufanschluss und des vom Zusatzvorlaufanschluss kommenden Heizkreismediums die Temperatur des Heizkreismediums an einem gemeinsamen Austritt bzw. an einem zentralen Hauptvorlaufanschluss des Heizkessels, in den einerseits der Vorlaufanschluss und andererseits der Zusatzvorlaufanschluss ausmünden, exakt eingestellt werden. Je stärker dabei der Vorlaufanschluss verschlossen wird, desto mehr Heizkreismedium wird dabei über die oben genannte Öffnung in den Kesselraum eingebracht und desto heißer wird das Heizkreismedium dann am oben genannten, gemeinsamen Austritt sein.In other words, the heating boiler according to the invention is characterized by the fact that with the help of this special flow guidance construction it is possible in a simple manner to guide the relatively cool heating circuit medium arriving at the return connection from the heating circuit equipped with a heating circuit pump through the boiler room to the flow connection with practically no thermal influence . Since hotter heating circuit medium coming directly from the boiler room is also available via the additional flow connection, the temperature of the heating circuit medium at a common outlet or at a central main flow connection of the boiler, in the flow connection on the one hand and the additional flow connection on the other hand can be set exactly. The tighter the flow connection is closed, the more heating circuit medium will flow through the opening mentioned above brought into the boiler room and the hotter the heating circuit medium will then be at the common outlet mentioned above.
Die Maßgabe, dass an der Strömungsführung eine Öffnung vorgesehen ist, bedeutet dabei, dass mindestens eine Öffnung vorgesehen ist. Besonders bevorzugt sind allerdings mehrere Öffnungen vorgesehen, über die vom Rücklaufanschluss kommendes, vergleichsweise kaltes Heizkreismedium in den Kesselraum einströmen kann. Ob dabei viel oder wenig Heizkreismedium vom Rücklaufanschluss in den Kesselraum strömt, wird, wie bereits erläutert, über die Einrichtung festgelegt.The requirement that an opening is provided on the flow guide means that at least one opening is provided. It is particularly preferred, however, to provide a plurality of openings through which comparatively cold heating circuit medium coming from the return connection can flow into the boiler room. Whether a lot or little heating circuit medium flows from the return connection into the boiler room is, as already explained, determined by the device.
Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Heizkessels ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the boiler according to the invention result from the dependent patent claims.
Der Vollständigkeit halber wird noch auf das weiter abliegende Dokument
Der erfindungsgemäße Heizkessel einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche 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 patent claims, is explained in more detail below with reference to the graphic representation of a preferred exemplary embodiment.
Es zeigt schematisch
Figur 1- den erfindungsgemäßen Heizkessel mit der Einrichtung zur Einstellung einer wahlweise durch den Vorlaufanschluss und/oder über die Öffnung durch den Zusatzvorlaufanschluss strömenden Vorlaufmenge an Heizkreismedium.
- figure 1
- the heating boiler according to the invention with the device for setting a flow rate of heating circuit medium flowing either through the flow connection and/or via the opening through the additional flow connection.
Gemäß der einzigen Figur besteht der erfindungsgemäße Heizkessel, der - was nicht extra dargestellt ist - vorzugsweise als Biomassekessel, insbesondere Pelletkessel, oder auch als Brennwertkessel ausgebildet ist, zunächst in bekannter Weise aus einem von einem Heizkreismedium (insbesondere Wasser) durchströmten Kesselraum 1, der einen Rücklaufanschluss 2 zur Zuführung des Heizkreismediums zum Kesselraum 1 und sowohl einen Vorlaufanschluss 3 als auch einen Zusatzvorlaufanschluss 4 zur Abführung des Heizkreismediums aus dem Kesselraum 1 aufweist, wobei der Rücklaufanschluss 2 in eine im Kesselraum 1 angeordnete und eine Öffnung 5.1 zum Kesselraum 1 aufweisende Strömungsführung 5 ausmündend ausgebildet ist.According to the only figure, the heating boiler according to the invention, which - which is not shown separately - is preferably designed as a biomass boiler, in particular a pellet boiler, or also as a condensing boiler, consists initially in a known manner of a
Darüber hinaus ist in bekannter Weise bevorzugt vorgesehen, dass der Kesselraum 1 eine Brennkammer 8 mindestens teilweise umschließend ausgebildet ist. Bei der in der einzigen Figur dargestellten Lösung wird dabei die Brennkammer 8 vollständig vom Kesselraum 1 umschlossen, wobei der Kesselraum 1 mindestens eine ein fluiddicht abgeschlossenes Volumen begrenzende Außenwandung 1.1 aufweist.In addition, it is preferably provided in a known manner that the
Weiterhin ist vorgesehen, dass die Strömungsführung 5 in den Vorlaufanschluss 3 ausmündend ausgebildet (also - abgesehen von der Öffnung 5.1 - fluiddicht verbunden) und eine Einrichtung 6 zur Einstellung einer wahlweise durch den Vorlaufanschluss 3 und/oder über die Öffnung 5.1 durch den Zusatzvorlaufanschluss 4 strömenden Vorlaufmenge an Heizkreismedium vorgesehen ist.It is also provided that the flow guide 5 is designed to open out into the flow connection 3 (i.e. - apart from the opening 5.1 - connected in a fluid-tight manner) and a
Wie eingangs bereits erläutert, ist dabei besonders bevorzugt vorgesehen, dass die Strömungsführung 5 nicht nur eine, sondern mehrere Öffnungen 5.1 (beispielsweise in Form von runden Löchern) aufweist, damit das vom Rücklaufanschluss 2 kommende Heizkreismedium möglichst gleichmäßig in den Kesselraum 1 einströmen kann. Dabei sind weiterhin besonders bevorzugt die Öffnungen 5.1 alle auf der selben Seite der Strömungsführung 5 ausgebildet.As already explained at the outset, it is particularly preferable for the flow guide 5 to have not just one but several openings 5.1 (e.g. in the form of round holes) so that the heating circuit medium coming from the
Damit dabei relativ kaltes, vom Rücklaufanschluss 2 kommendes Heizkreismedium nicht direkt von außen gegen die Brennkammer 8 bzw. deren Wandung strömt und diese damit unerwünscht stark abkühlt, ist die Öffnung 5.1 bzw. sind die Öffnungen 5.1 in Richtung Außenwandung 1.1 des Kesselraums 1, an der vorzugsweise auch der Vorlaufanschluss 3 und der Zusatzvorlaufanschluss 3 angeordnet sind, weisend angeordnet.So that relatively cold heating circuit medium coming from the
Erfindungsgemäß ist vorgesehen, dass die Strömungsführung 5 rohrförmig 15 ausgebildet ist, um das Heizkreismedium abgesehen von abströmendem Heizkreismedium an der bzw. den oben genannten Öffnungen 5.1 isoliert vom Heizkreismedium im Kesselraum 1 zu führen.According to the invention, it is provided that the flow guide 5 is tubular 15 in order to guide the heating circuit medium isolated from the heating circuit medium in the
Wie weiterhin aus der einzigen Figur ersichtlich, ist ferner bevorzugt vorgesehen, dass die Strömungsführung 5 wahlweise benachbart und überwiegend entlang einer Außenwandung 1.1 des Kesselraums 1 und/oder zwischen der Außenwandung 1.1 und der Brennkammer 8 angeordnet ist.As can also be seen from the single figure, it is also preferably provided that the flow guide 5 is optionally arranged adjacent and predominantly along an outer wall 1.1 of the
Gemäß der besonders bevorzugten, in der einzigen Figur dargestellten Ausführungsform ist ferner vorgesehen, dass die Strömungsführung 5 zwischen dem Rücklaufanschluss 2 und dem Vorlaufanschluss 3 einstückig ausgebildet ist, d. h. Heizkreismedium kann die Strömungsführung 5 nur über die Öffnung 5.1 bzw. Öffnungen 5.1 oder über den Vorlaufanschluss 3 verlassen.According to the particularly preferred embodiment shown in the single figure, it is also provided that the flow guide 5 is designed in one piece between the
Weiterhin ist vorgesehen, dass der Vorlaufanschluss 3 und der Zusatzvorlaufanschluss 4 in einen gemeinsamen, hier außerhalb des Kesselraums 1 angeordneten Hauptvorlaufanschluss 7 ausmündend ausgebildet sind. Darüber hinaus ist vorzugsweise vorgesehen, dass der Vorlaufanschluss 3 und der Zusatzvorlaufanschluss 4 auf gleicher Höhe am Kesselraum 1 angeordnet sind. Alternativ (nicht extra dargestellt) kann auch vorgesehen sein, dass der Hauptvorlaufanschluss 7 innerhalb des Kesselraums 1 mit dem Vorlaufanschluss 3 und dem Zusatzvorlaufanschluss 4 verbunden ausgebildet ist, d. h. diese beiden Anschlüsse 3, 4, vorzugsweise zusätzlich aber auch die Einrichtung 6 zur Einstellung der jeweiligen Menge an Heizkreismedium, sind dann komplett innerhalb des Kesselraums 1 positioniert.Furthermore, it is provided that the
Gemäß der erfindungsgemäßen Lösung wird somit heißes Heizkreismedium über den Zusatzvorlaufanschluss 4 entsprechend der Einstellung der Einrichtung 6 am Hauptvorlaufanschluss 7 zugemischt, wobei das Heizkreismedium über die Öffnung 5.1 bzw. Öffnungen 5.1 in den Kesselraum 1 zugeführt und dort erwärmt wird. Die Öffnungen 5.1 sind dabei beabstandet zum Zusatzvorlaufanschluss 4 angeordnet, um einen hydraulischen Kurzschluss zu vermeiden.According to the solution according to the invention, hot heating circuit medium is thus mixed in via the
Bezüglich der Einrichtung 6 ist schließlich besonders bevorzugt vorgesehen, dass diese wahlweise als vorzugsweise bezüglich ihrer Durchflussmenge kontinuierlich verstellbares Ventil und/oder mittels einer Heizungsregelung betätigbar ausgebildet ist. Außerdem ist bevorzugt vorgesehen, dass die Einrichtung 6 wahlweise am Vorlaufanschluss 3 und/oder zwischen der Strömungsführung 5 und dem Hauptvorlaufanschluss 7 angeordnet ist.Finally, with regard to the
Der erfindungsgemäße Heizkessel funktioniert wie folgt:
Ausgangspunkt der nachfolgenden Erläuterung ist, dass die Einrichtung 6 bzw. das Ventil geschlossen ist, d. h. ein Abströmen von Heizkreismedium über den Vorlaufanschluss 3 zum Hauptvorlaufanschluss 7 ist vollständig unterbunden. Dies hat zur Folge, dass über den Rücklaufanschluss 2 zum Heizkessel zurückgeführtes Heizkreismedium über die Öffnungen 5.1 in den Kesselraum 1 strömen muss. Dies wiederum führt dazu, dass das in den Kesselraum 1 eingebrachte Heizkreismedium von der Wärme abgebenden Brennkammer 8 erwärmt wird. Außerdem muss aus Gründen der Kontinuität, da ja der Vorlaufanschluss 3 verschlossen ist, die Menge an Heizkreismedium, die über den Rücklaufanschluss 2 dem Kesselraum 1 zugeführt wurde, über den Zusatzvorlaufanschluss 4 abgeführt werden, was gleichzeitig bedeutet, dass das am Hauptvorlaufanschluss 7 ankommende Heizkreismedium maximal erwärmt wird.The boiler according to the invention works as follows:
The starting point for the following explanation is that the
Wird nun die Einrichtung 6 bzw. das Ventil vollständig geöffnet, so besteht - sofern der Strömungswiderstand der Strömungsführung 5 zwischen dem Rücklaufanschluss 2 und dem Vorlaufanschluss 3 hinreichend niedrig ist - für das Heizkreismedium keine Veranlassung bzw. Notwendigkeit mehr über die Öffnungen 5.1 in den Kesselraum 1 zu strömen. Es kann vielmehr praktisch ungehindert vom Rücklaufanschluss 2 über die Strömungsführung 5 zum Vorlaufanschluss 3 und von dort zum mit einem Heizkreis mit Heizkreispumpe (nicht extra dargestellt, weil allgemein bekannt) verbundenen Hauptvorlaufanschluss 7 strömen. Da das Heizkreismedium dabei von der Strömungsführung 5 gegenüber dem Kesselraum 1 abgeschirmt ist, wird es, wenn überhaupt, nur wenig erwärmt, d. h. die Temperatur des Heizkreismediums am Hauptvorlaufanschluss 7 entspricht in etwa der Temperatur des Heizkreismedium am Rücklaufanschluss 2.If the
Aus den beiden voranstehend beschriebenen, gewissermaßen extremen Möglichkeiten und der Existenz des Ventils ergibt sich schließlich der besondere Vorteil der erfindungsgemäßen Lösung, nämlich über die Einstellung der Einrichtung 6 die Temperatur des Heizkreismediums am Hauptvorlaufanschluss 7 beeinflussen zu können, und zwar - bei voll geöffneter Einrichtung 6 - im Grunde unabhängig von der von der Brennkammer 8 an den Kesselraum 1 abgegebenen Wärme und dies bei gleichbleibendem Volumenstrom des Heizkreismediums.The two extreme possibilities described above and the existence of the valve ultimately result in the special advantage of the solution according to the invention, namely being able to influence the temperature of the heating circuit medium at the
