Abstract
The heating plant has a fuel cell arrangement and a parallel additional burner. Both are located in a common or two separate housing/s, formed as low pressure chamber/s. The housing has a common combined combustion air outlet pipe (10,17). The air and exhaust pipes (9,15,7,8) of additional burner and fuel cell arrangement, extend through a common collector (16), which is connected to the combustion air outlet pipe. The air pipe (9) leading to the additional burner is connected to the combustion air pipe (17) via a return valve (14) located in a dividing wall (18), through which the exhaust pipe also extends.
Description
<Desc/Clms Page number 1>
Die Erfindung bezieht sich auf eine Heizeinrichtung gemäss dem Oberbegriff des Anspruches 1.
Bei bekannten derartigen Heizeinrichtungen sind getrennte, in separaten Gehäusen angeordnete Geräte, eben eine Brennstoffzellenanordnung und ein Zusatzbrenner mit separatem Wärmetauscher, vorgesehen, wobei gegebenenfalls die Abgase der Brennstoffzellenanordnung über einen separaten Wärmetauscher geführt werden
Dabei ergibt sich der Nachteil eines erheblichen konstruktiven Aufwandes.
Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und eine Heizeinrichtung der eingangs erwähnten Art vorzuschlagen, die sich durch einen sehr einfachen Aufbau auszeichnet.
Erfindungsgemäss wird dies bei einer Heizeinrichtung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht
Durch die vorgeschlagene Anordnung im Gehäuse, bzw der Unterdruckkammer und die gewählte Luftführung kann im Falle eines Fehlers, z B bei einem CO-Austritt aus dem Reformer der Brennstoffzelle, sichergestellt werden, dass keine gefahrlichen Gase, bzw Abgase in den Aufstellungsraum gelangen können Ausserdem ist durch die Anordnung der Rückschlagklappe in der vom zum Zusatzbrenner fuhrenden Abgasleitung durchsetzten Trennwand ist sichergestellt, dass bei ausser Betrieb befindlichem Zusatzbrenner auch unter ungünstigen Verhältnissen keine Abgase über den Zusatzbrenner in die Zuluftleitung der Brennstoffzellenanordnung gelangen können.
So lässt die Rückschlagklappe nur eine Durchströmung in Richtung zum Zusatzbrenner zu, nicht aber in der Gegenrichtung
Bei ausser Betrieb befindlicher Brennstoffzellenanordnung besteht aufgrund ihres hohen Durchströmungswiderstandes Gefahr einer Durchströmung von deren Abgasseite zur Frischluftseite praktisch nicht, wobei überdies die Brennstoffzellenanordnungen meist mit einer geräteintemen Rückschlagklappe versehen sind, die eine solche Durchströmung ohnehin verhindert
In diesem Zusammenhang ist es besonders günstig die Merkmale des Anspruches 2 vorzusehen.
Durch die Merkmale des Anspruches 3 kann anfallendes Kondensat sicher abgeleitet werden.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen die Fig. 1 und 2 zwei verschiedene Ausführungsformen einer Verzweigung der zu der Brennstoffzellenanodnung bzw dem Zusatzbrenner führenden kombinierten Zuluft-Abgasleitungen
Die zur Führung der gesamten Abgase 3 und der gesamten Zuluft 4 vorgesehene kombinierte Zuluft- Abgasleitung 10,17 ist an einem Sammler 16 angeschlossen, von dem kombinierte Zuluft- Abluftleitungen, 9,15, bzw. 7,8 zu einem Zusatzbrenner, bzw einer Brennstoffzellenanrodnung führen, die beide nicht dargestellt und in einem im wesentlichen luftdichten Gehäuse angeordnet sind
Dabei führt die Leitung 15 die Frischluft 5 zum Zusatzbrenner und die Leitung 9 das entstandene Abgas 1 des Zusatzbrenners von diesem zum Sammler 16.
Weiters führt die Leitung 7 die Frischluft 8 zur Brennstoffzellenanordnung und die Leitung 8 das von dieser stammende Abgas 2 zum Sammler 16.
Im Sammler 16 ist eine von der Abgasleitung 9 durchsetzte Trennwand 18 angeordnet, in der eine Rückschlagklappe 14 angeordnet ist Diese Ruckschlagklappe 14 erlaubt eine Strömung der Frischluft in Richtung des Pfeiles 13, nicht aber entgegen dieser Strömungsnchtung
Im Bereich des Sammlers 16 sind die Abgasleitungen 8, 9 miteinander und mit der Abgasleitung 10 verbunden. Dabei ist im Bereich der Verbindungsstelle ein Kondensatablauf 12 mit einem Syphon 11vorgesehen.
Die beiden Ausführungsformen nach den Fig 1 und 2 unterscheiden sich dadurch, dass bei der Ausführungsform nach der Fig 1 die Rückschlagklappe 14 in einem horizontal verlaufenden Abschnitt der Trennwand 18 angeordnet und daher durch Schwerkraft gegen die geschlossene Stellung vorgespannt ist.
Bei der Ausführungsform nach der Fig 2 ist die Rückschlagklappe 14 in einem vertikal verlaufenden Bereich der Trennwand 18 angeordnet In diesem Fall ist es zweckmässig die Rückschlagklappe 14 mit einer Feder gegen die geschlossene Stellung vorzuspannen.

The invention relates to a heating device according to the preamble of claim 1.
In known heating devices of this type, separate devices arranged in separate housings, in other words a fuel cell arrangement and an additional burner with a separate heat exchanger, are provided, the exhaust gases of the fuel cell arrangement possibly being conducted via a separate heat exchanger
This results in the disadvantage of considerable design effort.
The aim of the invention is to avoid this disadvantage and to propose a heating device of the type mentioned at the outset, which is distinguished by a very simple construction.
According to the invention, this is achieved in a heating device of the type mentioned at the outset by the characterizing features of claim 1
The proposed arrangement in the housing or the vacuum chamber and the selected air duct can ensure in the event of a fault, for example in the event of CO leakage from the reformer of the fuel cell, that no dangerous gases or exhaust gases can get into the installation space The arrangement of the non-return valve in the partition wall through which the exhaust pipe leading to the additional burner leads ensures that when the additional burner is out of operation, even under unfavorable conditions, no exhaust gases can get into the supply air line of the fuel cell arrangement via the additional burner.
The check valve only allows a flow in the direction of the additional burner, but not in the opposite direction
When the fuel cell arrangement is out of operation, there is practically no risk of a flow from its exhaust gas side to the fresh air side due to its high flow resistance, and moreover the fuel cell arrangements are usually provided with a non-return valve that prevents such a flow anyway
In this context, it is particularly advantageous to provide the features of claim 2.
Due to the features of claim 3, condensate can be safely discharged.
The invention will now be explained in more detail with reference to the drawing. 1 and 2 show two different embodiments of a branching of the combined supply air exhaust gas lines leading to the fuel cell arrangement or the additional burner
The combined supply air exhaust gas line 10, 17 provided for guiding the entire exhaust gases 3 and the entire supply air 4 is connected to a collector 16, from which combined supply air / exhaust air lines 9, 15, or 7, 8 to an additional burner or a fuel cell arrangement lead, both of which are not shown and are arranged in an essentially airtight housing
The line 15 leads the fresh air 5 to the additional burner and the line 9 the resulting exhaust gas 1 of the additional burner from the latter to the collector 16.
Furthermore, line 7 leads the fresh air 8 to the fuel cell arrangement and line 8 the exhaust gas 2 originating therefrom to the collector 16.
Arranged in the collector 16 is a partition wall 18, through which the exhaust gas line 9 passes, in which a non-return flap 14 is arranged. This non-return flap 14 allows fresh air to flow in the direction of arrow 13, but not against this flow direction
In the area of the collector 16, the exhaust pipes 8, 9 are connected to one another and to the exhaust pipe 10. A condensate drain 12 with a siphon 11 is provided in the area of the connection point.
The two embodiments according to FIGS. 1 and 2 differ in that, in the embodiment according to FIG. 1, the check valve 14 is arranged in a horizontally running section of the partition wall 18 and is therefore biased against the closed position by gravity.
In the embodiment according to FIG. 2, the non-return flap 14 is arranged in a vertical region of the partition wall 18. In this case, it is expedient to pretension the non-return flap 14 with a spring against the closed position.
