Description

Die Erfindung bezieht sich auf einen Abgasadapter für ein Heizgerät mit Rekuperator.The invention relates to an exhaust gas adapter for a heater with recuperator.

Brennstoffbetriebene Heizgeräte mit Rekuperatoren zur Wirkungsgradsteigerung sind aus dem Stand der Technik bekannt. Dabei wird das Abgas eines Heizungsbrenners, das in einem ersten Wärmetauscher abgekühlt wurde, mittels kalten Brauchwassers weiter abgekühlt. Während mittels Heizungswasser das Abgas minimal auf Heizungsrücklauftemperatur abgekühlt werden kann, kann bei Brauchwasserkühlung das Abgas auf minimal die Temperatur des kalten Brauchwassers abgekühlt werden.Fuel-operated heaters with recuperators to increase efficiency are known from the prior art. In this case, the exhaust gas of a heating burner, which has been cooled in a first heat exchanger, further cooled by means of cold process water. While by means of heating water, the exhaust gas can be minimally cooled to the heating return temperature, the waste gas can be cooled down to a minimum of the temperature of the cold process water during process water cooling.

Heizgeräte mit Rekuperatoren sind aus dem Stand der Technik bekannt. In einer vorteilhaften Ausgestaltung kann ein konventionelles, wandhängendes Heizgerät durch einen Rekuperator ergänzt werden, welcher zwischen das Heizgerät und die Wand montiert wird, so dass das Heizgerät am an der Wand montierten Rekuperator befestigt wird. Hierdurch entsteht eine kompakte Einheit mit wenigen Befestigungspunkten an der Wand.Heaters with recuperators are known from the prior art. In an advantageous embodiment, a conventional, wall-mounted heater can be supplemented by a recuperator, which is mounted between the heater and the wall, so that the heater is attached to the wall-mounted recuperator. This creates a compact unit with few attachment points on the wall.

Hierbei ergibt sich das Problem, dass - insbesondere beim Nachrüsten - das Abgas des Heizgerätes kompakt in den Rekuperator und von diesem in die vorhandenen Anschlüsse einer Abgasanlage geleitet werden müssen.This results in the problem that - especially when retrofitting - the exhaust gas of the heater must be compactly routed into the recuperator and from this into the existing connections of an exhaust system.

Der Erfindung liegt die Aufgabe zugrunde, einen kompakten Anschluss für ein brenngasbetriebenes Heizgerät mit Rekuperator zu schaffen, mittels dessen vorhandene Installationen weiter benutzt werden können.The invention has for its object to provide a compact connection for a gas-fired heater with recuperator, by means of which existing installations can be used.

Dies wird gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass bei einem Heizgerät mit Rekuperator ein Abgasadapter derart gestaltet ist, dass der Abgasadapter das Heizgerät mit dem Rekuperator derart verbindet, dass die Kombination wie ein konventionelles Heizgerät mit einem konventionellen 90°-Abgasrohrbogen an ein konventionelles Abgasrohr angeschlossen werden kann.This is achieved according to the features of independent claim 1, characterized in that in a heater with recuperator an exhaust adapter is designed such that the exhaust adapter connects the heater with the recuperator such that the combination as a conventional heater with a conventional 90 ° -Abgasrohrbogen a conventional exhaust pipe can be connected.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments of the invention will become apparent from the features of the dependent claims.

Die Erfindung wird nun anhand der Figuren detailliert erläutert. Hierbei zeigen

  • Figur 1 den erfindungsgemäßen Abgasadapter auf der Kombination aus Heizgerät und Rekuperator von oben,
  • Figur 2 denselben Gegenstand von der Seite,
  • Figur 3 denselben Gegenstand von vorne,
  • Figur 4 einen alternativen, erfindungsgemäßen Abgasadapter von oben und
  • Figur 5 den alternativen Abgasadapter von der Seite.
The invention will now be explained in detail with reference to FIGS. Show here
  • FIG. 1 the exhaust gas adapter according to the invention on the combination of heater and recuperator from above,
  • FIG. 2 the same object from the side,
  • FIG. 3 the same object from the front,
  • FIG. 4 an alternative, inventive exhaust adapter from above and
  • FIG. 5 the alternative exhaust adapter from the side.

Die Figuren 1 bis 3 zeigen von oben, der Seite und von hinten ein brennstoffbeheiztes Heizgerät 2, das mit seinem Heizgerätegehäuse 3 an einem Rekuperatorgehäuse 5 eines Rekuperator 4 über die Rekuperatorvorderseite 10 über nicht genauer dargestellte Befestigungsmittel verbunden ist. An der Rekuperatorrückwand 9 sind nicht genauer dargestellte Mitteln zur Wandbefestigung angebracht. Das Heizgerät 2 verfügt über einen nach oben gerichteten Heizungsabgasrohranschluss 6, der Rekuperator 4 über einen Abgaseintritt 7 und einen Abgasaustritt 8. Ein Abgasadapter 1 verbindet den Heizungsabgasrohranschluss 6 des Heizgerätes 2 mit dem Abgaseintritt 7 des Rekuperators 4 und den Abgasaustritt 8 des Rekuperators 4 mit einem Adapterabgasrohranschluss 11, wobei die Richtung der Mündung des Heizungsabgasrohranschlusses 6 und die Richtung der Mündung des Adapterabgasrohranschlusses 11 einen rechten Winkel bilden und zudem in einer Ebene senkrecht zur Rekuperatorrückwand 9 liegen.The FIGS. 1 to 3 show from above, the side and from behind a fuel-fired heater 2, which is connected to its heater housing 3 to a recuperator 5 of a recuperator 4 via the recuperator front 10 via fastening means not shown in detail. At the recuperator rear wall 9 not shown in detail means are mounted on the wall. The heater 2 has an upwardly directed Heizungsabgasrohranschluss 6, the recuperator 4 via an exhaust gas inlet 7 and an exhaust outlet 8. An exhaust gas adapter 1 connects the Heizungsabgasrohranschluss 6 of the heater 2 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust gas outlet 8 of the recuperator 4 with a Adapter exhaust pipe connection 11, wherein the direction of the mouth of the Heizungsabgasrohranschlusses 6 and the direction of the mouth of the Adapterabrohrrohranschlusses 11 form a right angle and also lie in a plane perpendicular to the Rekuperatorrückwand 9.

Der Abgasadapter 1, der den Heizungsabgasrohranschluss 6 mit dem Abgaseintritt 7 des Rekuperators 4 und den Abgasaustritt 8 des Rekuperators 4 mit dem Adapterabgasrohranschluss 11 mittels Abgasleitungen 12 verbindet, umgibt - wie in den Figuren 1 bis 3 gezeigt - diese Abgasleitungen 12 frischluftführend.The exhaust gas adapter 1, which connects the heater exhaust pipe connection 6 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust gas outlet 8 of the recuperator 4 with the adapter exhaust pipe connection 11 by means of exhaust pipes 12, surrounds - as in FIGS FIGS. 1 to 3 shown - this exhaust pipes 12 fresh air.

Alternativ kann - wie in den Figuren 4 und 5 dargestellt - der Abgasadapter 1 den Heizungsabgasrohranschluss 6 mit dem Abgaseintritt 7 des Rekuperators 4 und den Abgasaustritt 8 des Rekuperators 4 mit dem Adapterabgasrohranschluss 11 in koaxialen Leitungen verbinden, wobei die Abgasleitungen 12 von Frischluftleitungen 13 umgeben sindAlternatively - as in the FIGS. 4 and 5 shown - the exhaust adapter 1 connect the Heizungsabgasrohranschluss 6 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust outlet 8 of the recuperator 4 with the adapter exhaust pipe 11 in coaxial lines, the exhaust pipes 12 are surrounded by fresh air ducts 13

Der Abgasadapter 1 verfügt bei beiden Varianten vom mit dem Heizungsabgasrohranschluss 6 verbindbaren Eintritt bis zum Adapterabgasrohranschluss 11 über die gleiche Erstreckung wie ein Standardabgasbogen. Hierdurch ist gewährleistet, dass Standardabgasrohre zum Anschluss der Kombination aus Heizgerät 2 und Rekuperator 4 Verwendung finden kann. Der Abgasadapter 1 verfügt vom mit dem Heizungsabgasrohranschluss 6 verbindbaren Eintritt bis zum Adapterabgasrohranschluss 11 über die gleiche horizontale Erstreckung wie die Summe der Tiefe t des Rekuperatorgehäuses 5, die sich aus dem Abstand zwischen Rekuperatorrückwand 9 und Rekuperatorvorderseite 10 ergibt, plus einem Standardabgasbogen. Somit ist eine einfache Ergänzung möglich. Bei einer Nachrüstung kann ein montiertes Heizgerät 2 demontiert, mit dem Rekuperator 4 verbunden und über den Abgasadapter 1 wieder mit der bereits vorhandenen Abgasleitung verbunden werden. Bei einer Neumontage können Standardkomponenten verwendet werden.In both variants, the exhaust gas adapter 1 has the same extent as a standard exhaust gas bend from the inlet connectable to the heating exhaust gas pipe connection 6 to the adapter exhaust gas pipe connection 11. This ensures that standard exhaust pipes can be used to connect the combination of heater 2 and recuperator 4 use. The exhaust adapter 1 has from the connectable to the Heizungsabgasrohranschluss 6 inlet to the adapter exhaust pipe 11 over the same horizontal extent as the sum of the depth t of the Rekuperatorgehäuses 5, resulting from the distance between Rekuperatorrückwand 9 and Rekuperatorvorderseite 10, plus a standard exhaust bend. Thus, a simple supplement is possible. When retrofitting a mounted heater 2 can be dismantled, connected to the recuperator 4 and connected via the exhaust adapter 1 again with the existing exhaust pipe. For a new installation standard components can be used.

Beim Heizungsbetrieb strömen die Abgase des Heizungsgerätes 2, welche in einem nicht dargestellten Primärwärmetauscher thermische Energie auf einen Heizungskreislauf abgegeben haben und somit minimal auf Heizungsrücklauftemperatur abgekühlt werden, durch den Heizungsabgasrohranschluss 6 über den Abgasadapter 1 in den Abgaseintritt 7 des Rekuperators 4. Im Rekuperator 4 gibt das Abgas in einem nicht dargestellten Wärmetauscher weitere thermische Energie an frisches Brauchwasser ab. Das so aufgeheizte Brauchwasser strömt aus dem Rekuperator 4 zum Heizungsgerät 2, wo es in konventioneller Art weiter auf Solltemperatur erhitzt wird. Das somit weiter abgekühlte Abgas strömt aus dem Abgasaustritt 8 des Rekuperators 4 über den Abgasadapter 1 zu dem Adapterabgasrohranschluss 11 und von dort über eine nicht weiter dargestellte Abgasleitung in die Umgebung.In the heating mode, the exhaust gases of the heating device 2, which have delivered thermal energy to a heating circuit in a primary heat exchanger, not shown, and thus minimized to heating return temperature, through the Heizungsabgasrohranschluss 6 via the exhaust adapter 1 in the exhaust gas inlet 7 of the recuperator 4. In the recuperator 4 are the exhaust gas in a heat exchanger, not shown, from further thermal energy to fresh hot water. The hot water heated in this way flows out of the recuperator 4 to the heating device 2, where it is further heated to the set temperature in a conventional manner. The thus further cooled exhaust gas flows from the exhaust gas outlet 8 of the recuperator 4 via the exhaust gas adapter 1 to the adapter exhaust pipe connection 11 and from there via a not shown exhaust pipe into the environment.

Bei der Variante gemäß den Figuren 1 bis 3 strömt Frischluft aus dem koaxialen Abgasrohr über den Abgasadapter 1 direkt zum Heizungsgerät 2. Hingegen strömt bei der Variante gemäß Figuren 4 und 5 Frischluft aus dem koaxialen Abgasrohr über den Abgasadapter 1 zunächst in den Rekuperator 4 und von dort zum Heizungsgerät 2. Bei zuletzt genannter Variante sorgt ein Luftmantel im Rekuperator 4 für eine Wärmerückgewinnung der Wärmeverluste des Rekuperators 4 in die Frischluft.In the variant according to the FIGS. 1 to 3 Fresh air flows from the coaxial exhaust pipe via the exhaust adapter 1 directly to the heater 2. On the other hand flows in the variant according to FIGS. 4 and 5 Fresh air from the coaxial exhaust pipe via the exhaust adapter 1 first in the recuperator 4 and from there to the heater 2. In the last-mentioned variant provides an air jacket in the recuperator 4 for heat recovery of the heat losses of the recuperator 4 in the fresh air.

Wie bei jedem Wärmetauscher gilt der Grundsatz, dass das wärmere Medium minimal auf eine Temperatur oberhalb der Temperatur des kälteren Mediums abgekühlt werden kann, wobei die maximale Wärmeübertragung bei einer Durchströmung im Gegenstromprinzip erreicht wird. Abgase üblicher erdgasbetriebener Heizungsbrenner 2 besitzen einen Wasserdampfanteil von etwa 105 Gramm Wasserdampf pro trockenes Kilogramm Abgas. Der Taupunkt des Abgases liegt bei etwa 55°C. Speziell im Winter ist die Außenlufttemperatur niedriger als die Brauchwassertemperatur, so dass im Rekuperator nochmals Wärme vom Abgas auf die Frischluft übertragen werden kann. Da die Abgase im Wärmetauscher des Heizungsgerätes 2 bereits auf eine Temperatur deutlich unterhalb 100°C abgekühlt werden, besteht in keinem Fall eine Gefahr der Überhitzung im Rekuperator 3, wenn dieser keine Wärme mehr aufnehmen kann.As with any heat exchanger, the principle is that the warmer medium can be minimally cooled to a temperature above the temperature of the colder medium, the maximum heat transfer is achieved in a countercurrent flow. Exhaust gases of conventional natural gas powered heating burner 2 have a water vapor content of about 105 grams of water vapor per dry kilogram of exhaust gas. The dew point of the exhaust gas is around 55 ° C. Especially in winter, the outside air temperature is lower than the hot water temperature, so that in the recuperator heat can be transferred from the exhaust gas to the fresh air again. Since the exhaust gases in the heat exchanger of the heating device 2 are already cooled to a temperature well below 100 ° C, there is no risk of overheating in the recuperator 3, if it can no longer absorb heat.
