Abstract

In a hot water tank heated by fuel and provided with an annular compartment filled with water and arranged in a housing, the center of the compartment being traversed by a flue tube (5) heated by burned gas from a burner (7), an annular heating chamber (10) for the water of a heating installation is arranged between the flue tube (5) and the inner wall (28) of the water tank (33). The heating water may heat either the radiators of a heating installation or the inner wall of the water tank if a three-way valve (18) is switched. The temperature of the water which has been used is thereby independent from the heating temperature.

Description

Brennstoffbeheizter Wasserspeicher Fuel-heated water storage
Die vorliegende Erfindung bezieht sich auf einen brennstoffbeheizten Wasserspeicher gemäß dem Oberbegriff des Hauptanspruchs .The present invention relates to a fuel-heated water reservoir according to the preamble of the main claim.
Solche brennstoffbeheizten Wasserspeicher werden in der Regel zur Beheizung warmen Gebrauchswassers eingesetzt. Sie weisen einen hohlzylindrischen Wasserspeicher auf, dessen Zentrum von einem Flammrohr gebildet ist, das von Abgasen eines den Wasserspeicher erhitzenden Brenners durchstrichen ist. Um einen solchen brennstoffbeheizten Wasserspeicher zur Speisung einer Zentralheizungsanlage verwenden zu können, ist es bereits vorgeschlagen worden, in den Wasserspeicher eine Rohrschlange einzubringen, die an die Zentralheizungsanlage angeschlossen wird. Der Nachteil hierbei ist, daß der gesamte Brauchwasserinhalt aufgeheizt werden muß, bevor an die Zentralheizungsanlage warmes Wasser abgegeben werden kann. Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, diesen Nachteil zu vermeiden. Zur Lösung der Aufgabe schlägt die Erfindung die aus dem kennzeichnenden Teil des Hauptanspruchs ersichtlichen Merkmale vor.Such fuel-heated water storage tanks are generally used to heat warm service water. They have a hollow cylindrical water reservoir, the center of which is formed by a flame tube which is swept by exhaust gases from a burner that heats the water reservoir. In order to be able to use such a fuel-heated water reservoir for feeding a central heating system, it has already been proposed to insert a pipe coil into the water reservoir, which is connected to the central heating system. The disadvantage of this is that the entire hot water content must be heated before hot water can be delivered to the central heating system. The object of the present invention is to avoid this disadvantage. To achieve the object, the invention proposes the features evident from the characterizing part of the main claim.
Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der UnteranSprüche beziehungsweise gehen aus der nachfolgenden Beschreibung hervor, die ein Ausführungsbeispiel der Erfindung anhand der Figur der Zeichnung näher erläutert.Further refinements and particularly advantageous developments of the invention are the subject of the dependent claims or emerge from the following description, which explains an embodiment of the invention with reference to the figure of the drawing.
Die Figur zeigt eine schematische Längsschnittdarstellung eines gasbeheizten Speichers.The figure shows a schematic longitudinal sectional view of a gas-heated storage.
Der gasbeheizte Speicher weist ein mit einer Isolierschicht versehenes Gehäuse 1 auf, das aus einem Zylindermantel 2, einer Bodenplatte 3 und einer mit Ausnehmungen versehenen Deckplatte 4 besteht, die allseitig dicht miteinander verbunden sind.The gas-heated store has a housing 1 provided with an insulating layer, which consists of a cylinder jacket 2, a base plate 3 and a cover plate 4 provided with recesses, which are tightly connected to one another on all sides.
Das zentrale Innere des Gehäuses 1 ist von einem Flammrohr 5 gebildet, dem an seinem sich unten erweiternden Ende 6 ein Gasbrenner 7 zugeordnet ist, der über eine mit einem Brennstoffmagnetventil 8 versehene Gasleitung 9 gespeist ist. Statt Gas als Energie-träger könnte auch öl oder ein fester Brennstoff in Frage kommen. Die Wand des Flammrohres bildet einen Wärmetauscher zu einem sich um den Zylindermantel des Flammrohres erstreckenden doppelten Ringraum 10, der zwei Schenkel 11 und 12 bildet, die durch ein Trenn- blech 13 voneinander getrennt sind und die Form eines U's mit einer unten im Brennerbereich liegenden Umlenkung 14 aufweisen. An den inneren Schenkel 11 des doppelten Ringraums ist im Bereich des Deckels 4 eine Vorlaufleitung 15 angeschlossen, in der eine von einem Motor 16 angetriebene Umwälzpumpe 17 und ein Dreiwege- umschaltventil 18 angeordnet sind, welches von einem Stellmotor 19 verstellt werden kann. Der Motor 16 beziehungsweise der Stellmotor 19 sind über eine Stelleitung 20 an eine Regel- und Steuereinrichtung 21 angeschlossen, die über eine Leitung 22 das Magnetventil zum Brenner 7 beherrscht und an die über eine Meßleitung 23 ein Temperaturfühler 24 angeschlossen ist, der im Innenraum 25 des Wasserspeichers angeordnet ist. Das Flammrohr 5 und der Doppelringraum 10 bilden konzentrisch zu einer gemeinsamen Symmetrieachse liegende Zylinder- beziehungsweise Ringzylinderräume. Um den Doppelringraum 10 erstreckt sich ein weiterer Ringraum 26, der von dem Doppelringraum 10 durch einen dritten Ringraum 27 getrennt ist. Die einzelnen Ringräume 26, 27, 11 und 12 sind durch Ringbleche 28 voneinander getrennt. Während der dritte Ringraum über eine ringförmige Ausnehmung 29 im Bereich des Deckels mit der Atmosphäre in Verbindung steht, ist der weitere Ringraum 26 über einen Rücklaufleitungsanschluß 30 - gleichfalls im Bereich des Deckels 4 vorgesehen - mit einem Anschluß des Dreiwegeventils 18 verbunden. Vom Dreiwegeventil 18 führt eine Vorlaufleitung 31 zu einem nicht weiter dargestellten Verbraucher, der aus einer Serien- und/oder Parallelschaltung einer Vielzahl von Heizkörpern bestehen kann und der rücklaufseitig an feine Rücklaufleitung 32 angeschlossen ist, deren Anschlußstutzen im Bereich des Deckels in den äußeren Schenkel 12 des Doppelringraums 10 mündet.The central interior of the housing 1 is formed by a flame tube 5, to which a gas burner 7 is assigned at its end 6 which widens below and is fed via a gas line 9 provided with a fuel solenoid valve 8. Instead of gas as an energy source, oil or a solid fuel could also be used. The wall of the flame tube forms a heat exchanger for a double annular space 10 which extends around the cylinder jacket of the flame tube and which forms two legs 11 and 12 which are separated by a separating sheet 13 are separated from each other and have the shape of a U with a deflection 14 located below in the burner area. A flow line 15 is connected to the inner leg 11 of the double annular space in the area of the cover 4, in which a circulation pump 17 driven by a motor 16 and a three-way switch valve 18 are arranged, which can be adjusted by a servomotor 19. The motor 16 or the servomotor 19 are connected via a control line 20 to a regulating and control device 21, which controls the solenoid valve to the burner 7 via a line 22 and to which a temperature sensor 24 is connected via a measuring line 23, which in the interior 25 of the Water storage is arranged. The flame tube 5 and the double annulus 10 form cylinder or annular cylinder spaces lying concentrically to a common axis of symmetry. A further annular space 26 extends around the double annular space 10 and is separated from the double annular space 10 by a third annular space 27. The individual annular spaces 26, 27, 11 and 12 are separated from one another by annular plates 28. While the third annular space is connected to the atmosphere via an annular recess 29 in the area of the cover, the further annular space 26 is connected to a connection of the three-way valve 18 via a return line connection 30 - likewise provided in the area of the cover 4. From the three-way valve 18, a flow line 31 leads to a consumer, not shown, which can consist of a series and / or parallel connection of a large number of radiators and which is connected on the return side to fine return line 32, the connecting piece of which in the area of the cover in the outer leg 12 of the double annulus 10 opens.
Um den weiteren Ringraum 26 erstreckt sich der Innenraum 25 des Wasserspeichers 33, der nach innen von dem Trennblech 28 des weiteren Ringraums 16, von außen durch den Mantel 2 des Gehäuses 1 begrenzt ist.The interior 25 of the water reservoir 33 extends around the further annular space 26 and is delimited inwards by the separating plate 28 of the further annular space 16 and from the outside by the jacket 2 of the housing 1.
Im unteren Bereich 34 des Gehäuses 1 ist eine Verbindungsleitung 35 vorgesehen, die sich etwa von der tiefsten Stelle des weiteren Ringraums 26 zur Umlenkungsstelle 14 zwischen den beiden Schenkeln 11 und 12 des Doppelringraums 10 erstreckt. Sowohl die Schenkel 11 und 12 als auch die Ringräume 26 und 27 erweitern sich im unteren Bereich 34, desgleichen der Innenraum des Flammrohres 5. Diese Erweiterung geht zu Lasten des Innenraums 25 des Wasserspeichers 33, der nicht bis zum Bereich des Bodens 3 hinunterreicht, sondern im Abstand davor endet. In den Innenraum 25 mündet in dessen unteren Bereich ein Kaltwasserzulaufrohr 36, von ihm geht im obersten Bereich ein Brauchwasserzapfrohr 37 ab.In the lower region 34 of the housing 1, a connecting line 35 is provided, which extends approximately from the lowest point of the further annular space 26 to the deflection point 14 between the two legs 11 and 12 of the double annular space 10. Both the legs 11 and 12 and the annular spaces 26 and 27 expand in the lower region 34, as does the interior of the flame tube 5. This expansion is at the expense of the interior 25 of the water reservoir 33, which does not extend down to the region of the base 3, but instead ends at a distance from it. A cold water supply pipe 36 opens into the lower area of the interior 25, from which a service water tap pipe 37 branches off in the uppermost area.
Im unteren Bereich 34 kann die dem dritten Ringraum 27 zugewandte Innenseite des weiteren Ringraums 26 mit einer Isolierschicht 38 versehen sein. Der Temperaturfühler 24 ist im unteren Bereich 34 des Innenraums 25 des Wasserspeichers 33 angeordnet.In the lower region 34, the inside of the further annular space 26 facing the third annular space 27 can be provided with an insulating layer 38. The temperature sensor 24 is arranged in the lower region 34 of the interior 25 of the water reservoir 33.
Der brennstoffbeheizte Wasserspeicher hat folgende Funktion: Wenn dieser Speicher nur zur Bereitung warmen Gebrauchswassers eingesetzt wird und der Temperaturfühler 24 fordert Wärme an, so resul- tieren von der Steuer- und Regeleinrichtung 21 Stellsignale zum öffnen des Magnetventils 8, zum Anlaufen des Motors 16 der Umwälzpumpe 17, zum Verstellen des Dreiwegeventils 18 in eine solche Richtung, daß der Vorlauf 31 abgesperrt wird. Der Brenner geht in Betrieb und saugt Frischluft durch die Luftöffnung 29 und den dritten Ringraum 27 an. Das vom Brenner 7 erzeugte Abgas steigt im Flammrohr 5 auf und verlässt den Wasserspeicher über ein nicht weiter dargestelltes Abgasrohr in Fortsetzung des Flammrohres 5.The fuel-heated water storage tank has the following function: If this storage tank is only used to prepare warm service water and the temperature sensor 24 requests heat, the result is animals from the control and regulating device 21 control signals for opening the solenoid valve 8, for starting the motor 16 of the circulating pump 17, for adjusting the three-way valve 18 in such a direction that the flow 31 is shut off. The burner goes into operation and draws in fresh air through the air opening 29 and the third annular space 27. The exhaust gas generated by the burner 7 rises in the flame tube 5 and leaves the water reservoir via an exhaust gas tube, not shown, continuing the flame tube 5.
Die Abgase des Brenners beheizen hiermit das Flammrohr 5, von dem die Wärme auf den inneren Schenkel 11 des Doppelringraums 10 übertragen wird. Angetrieben durch die Umwälzpumpe zirkuliert hier Wasser, das von dem Dreiwegeventil über die Leitung 30 in den weiteren Ringraum 26 gelangt. Von hier strömt das Wasser über die Verbindungsleitung 35 zu Umlenkpunkt 14 des Doppelringraums 10, den es am oberen Ende des inneren Schenkels 11 verlässt und zwar durch die Vorlaufleitung 15. Es wird darauf hingewiesen, daß die Pumpe 17 auch in der Rücklaufleitung 30 angeordnet sein kann.The exhaust gases from the burner hereby heat the flame tube 5, from which the heat is transferred to the inner leg 11 of the double annulus 10. Driven by the circulation pump, water circulates here, which reaches the further annular space 26 from the three-way valve via line 30. From here, the water flows via the connecting line 35 to the deflection point 14 of the double annular space 10, which it leaves at the upper end of the inner leg 11, specifically through the supply line 15. It is pointed out that the pump 17 can also be arranged in the return line 30 .
Somit trägt das Umlaufwasser dazu bei, einerseits von den das Flammrohr durchstreichenden heißen Abgasen des Brenners Wärme aufzunehmen und zum anderen diese über das Blech 28, das den Innenraum 25 des Speicherbehälters 33 von dem Hohlzylinderraum des weiteren Ringraums trennt, abzugeben . Es findet somit eine indirekte Aufheizung des Gebrauchswassers statt, das durch Hineindrücken von frischem Kaltwasser durch den Zulaufstutzen 36 dem Warmwasserzapfstutzen 37 entnommen werden kann.The circulating water thus contributes, on the one hand, to absorb heat from the hot exhaust gases of the burner passing through the flame tube and, on the other hand, to dissipate it via the plate 28, which separates the interior 25 of the storage container 33 from the hollow cylinder space of the further annular space. There is thus an indirect heating of the service water, which by pushing in fresh cold water through the inlet nozzle 36 to the hot water nozzle 37 can be removed.
Soll hingegen mit dem brennstoffbeheizten Wasserspeicher die Heizungsanläge betrieben werden, so wird das Dreiwegeventil 18 durch den Stellmotor 19 entsprechend umgestellt. Die Pumpe fördert dann erhitztes Vorlaufwasser aus der Leitung 15 in die Vorlaufleitung 31 zu den nicht dargestellten Heizkörpern, die von denen das Wasser über die Rücklaufleitung 32 dem äußeren Schenkel 12 des Doppelringraums 10 und zwar an dessen oberen deckelseitigen Ende wieder zugeführt wird. Dieses kühle Rücklaufwasser durchströmt beide Schenkel des Doppelringraums und verlässt den Wasserspeicher durch die Vorlaufleitung 15.If, on the other hand, the heating systems are to be operated with the fuel-heated water reservoir, the three-way valve 18 is switched accordingly by the servomotor 19. The pump then conveys heated feed water from line 15 into the feed line 31 to the radiators (not shown), from which the water is returned via the return line 32 to the outer leg 12 of the double annulus 10, namely at its upper end on the cover side. This cool return water flows through both legs of the double annulus and leaves the water reservoir through the feed line 15.
Bei dieser Schaltung findet keine Aufheizung des Gebrauchswassers statt. Gegen Auskühlung ist das im Innenraum 25 des Wasserspeicherbehälters 33 gespeicherte Wasser gegenüber der kühlen Frischluft, die durch den dritten Ringraum 27 streicht, durch die Isolierung 38 weitestgehend geschützt. Es wäre möglich, die Isolierung über die gesamte Höhe des Gehäuses 1 an dem Blech 28 vorzunehmen, das den dritten Ringraum 27 außen gegenüber dem weiteren Ringraum 26 abschirmt, damit nicht bei Brauchwasseraufheizung das in den weiteren Ringraum 26 strömende Medium von der zugeführten frischen Zuluft gekühlt wird. Eine gleiche Isolierung könnte man auch außenseitig desjenigen Blechs 28 vornehmen, das den äußeren Schenkel 12 des Doppelringraums 10 begrenzt.This circuit does not heat the process water. The insulation 38 largely protects the water stored in the interior 25 of the water storage container 33 from the cool fresh air which passes through the third annular space 27. It would be possible to carry out the insulation over the entire height of the housing 1 on the sheet metal 28, which shields the third annular space 27 from the outside from the further annular space 26, so that the medium flowing into the further annular space 26 is not cooled by the fresh supply air supplied when the process water is heated becomes. The same insulation could also be carried out on the outside of the plate 28 which delimits the outer leg 12 of the double annulus 10.
Durch den konzentrischen Aufbau der einzelnen Ringräume ist es be- sonders gut möglich, das Gerät abgas- und abluftseitig über konzentrische Rohre an Schornsteine beziehungsweise Lüftungsschächte anzuschließen, hierin ein Frischluft- oder Abgasgebläse anzuordnen und auch mit einer Abgasklappe zu arbeiten.Due to the concentric structure of the individual annular spaces, it is It is particularly possible to connect the device on the exhaust and exhaust air sides to chimneys or ventilation shafts via concentric pipes, to place a fresh air or exhaust gas blower therein, and also to work with an exhaust flap.
Statt der Ringbleche, die aus Stahl oder Aluminium gefertigt sein können, können auch Keramikrohre verwendet werden. Es ist weiterhin möglich, den Wasserspeicher um 90° gekippt arbeiten zu lassen, sodaß also die Symmetrieachse nicht senkrecht, sondern waagerecht angeordnet ist und als Brenner einen Gas- oder Ölgebläsebrenner vorzusehen.Instead of the ring plates, which can be made of steel or aluminum, ceramic tubes can also be used. It is also possible to have the water reservoir tilted by 90 °, so that the axis of symmetry is not arranged vertically but horizontally and a gas or oil blower burner is provided as the burner.
Falls die Auskühlung über die Luftführung im dritten Ringraum zu groß ist, kann die Öffnung 29 verschlossen werden und eine neue Zuluftöffnung im Bereich des Bodendeckels 3 angeordnet werden.If the cooling via the air duct in the third annular space is too great, the opening 29 can be closed and a new supply air opening can be arranged in the area of the base cover 3.
Durch den luftführenden Ringraum 27 wird eine thermische Trennung des Brauchwassers von dem die Heizung speisenden Wasser möglich. Daraus ergibt sich der Vorteil, das Brauchwasser auf einer vom die Heizung speisenden Wasser abweichenden, insbesondere höheren Temperatur zu halten. The air-conducting annular space 27 enables thermal separation of the process water from the water supplying the heating. This has the advantage of keeping the process water at a temperature which differs from the water supplying the heating, in particular a higher temperature.
