Stand der TechnikState of the art

Aus DE 201 12 299 U1 ist eine Ionisationselektrode zur Flammenüberwachung bei einem Brenner bekannt, die einen Elektrodendraht aufweist, der in einem elektrisch isolierenden Körper geführt ist, wobei der elektrisch isolierende Körper mittels eines Halters an einer Wand einer Brennkammer des Brenners befestigt ist. Der Elektrodendraht ragt mit einer u-förmigen Umbiegung in die Flammen des Brenners hinein. Als Gegenpotential ist eine Masseelektrode vorgesehen, die ebenfalls in die Brennkammer des Brenners hineinragt und die mit ihrer Stirnfläche der stirnseitigen Umbiegung des Elektrodendrahtes gegenüberliegt. Zusätzlich ist die Masseelektrode mit einem Kanal zur Zuführung von Luft versehen, so dass die eingeführte Luft in die Überwachungsstrecke der Ionisationselektrode strömt.DE 201 12 299 U1 describes an ionization electrode for flame monitoring in one Burner known which has an electrode wire which is in an electrically insulating Body is guided, the electrically insulating body by means of a holder on a Wall of a combustion chamber of the burner is attached. The electrode wire protrudes with one U-shaped bend into the flame of the burner. As a counter potential is one Ground electrode provided, which also protrudes into the combustion chamber of the burner and with its end face the frontal bend of the electrode wire opposite. In addition, the ground electrode has a channel for the supply of Provide air so that the air introduced into the monitoring section of the Ionization electrode flows.

Aus DE 196 16 617 A1 ist eine Ionisationselektrode mit einer zugeordneten Masseelektrode für einen Zündbrenner bekannt. Um eine höhere Funktionssicherheit trotz eventuell auftretender Kriechströme zu gewährleisten, ist vorgesehen, dass ein Abschnitt der Masseelektrode durch den von der Zündflamme überstrichenen Bereich verläuft.DE 196 16 617 A1 describes an ionization electrode with an associated one Ground electrode for a pilot burner known. To ensure greater functional reliability despite to ensure any leakage currents that occur, it is provided that a section the ground electrode runs through the area covered by the pilot light.

Insbesondere bei der Verwendung von Brennkammern aus Aluminium bzw. Aluminiumlegierungen, wie beispielsweise bei Brennkammern für Brennwertgeräte, kann es zur Korrosion des Aluminiums bzw. der Aluminiumlegierung kommen. Die Korrosionsprodukte sind bei geringer Feuchte elektrisch leitend, wobei es durch abwechselnde Feucht-Trocken-Phasen aufgrund der elektrochemischen Spannungsreihen zu chemisch induzierten Strömen oder zu Gleichrichtungseffekten (Halbleitereffekt) kommen kann. Durch die auftretenden Fehlerströme ist es möglich, dass dem Gasfeuerungsautomat ein falsches Signal geliefert wird. Dabei kann es vorkommen, dass dem Gasfeuerungsautomat in der standby-Phase aufgrund des auftretenden Stroms mit dem Stromsignal eine Flamme gemeldet wird, obwohl der Brenner nicht in Betrieb ist. Die Folge wäre, dass das Heizgerät auf Störung geschaltet wird.Especially when using combustion chambers made of aluminum or Aluminum alloys, such as in combustion chambers for condensing boilers, can there is corrosion of the aluminum or the aluminum alloy. The Corrosion products are electrically conductive at low moisture levels, whereby it passes through alternating wet-dry phases due to the electrochemical voltage series to chemically induced currents or to rectification effects (semiconductor effect) can come. Due to the occurring fault currents, it is possible that the Automatic burner control unit delivers a wrong signal. It can happen that the burner control unit in the standby phase due to the current that occurs a flame is reported to the current signal even though the burner is not in operation. The result would be that the heater is switched to malfunction.

Aufgabe der vorliegenden Erfindung ist es, das Entstehen von Fremdströmen zu verhindern und damit die Störanfälligkeit des Heizgerätes zu verbessern.The object of the present invention is to prevent the creation of external currents prevent and thus improve the susceptibility to malfunction of the heater.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Wärmezelle mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass in der Brennkammer entstehende Korrosionsprodukte von dem Isolierkörper und dem Elektrodendraht der Messelektrode ferngehalten werden. Dadurch wird das Auftreten von Fremdströmen verhindert, welche bei Betauung entstehen und über den ebenfalls betauten Isolierkörper zum Elektrodendraht geleitet werden können. Dadurch wird die Störanfälligkeit des Heizgerätes verringert.The heat cell according to the invention with the characterizing features of the claim 1 has the advantage that corrosion products from the combustion chamber Insulating body and the electrode wire of the measuring electrode are kept away. Thereby prevents the occurrence of external currents, which arise during condensation and can also be conducted to the electrode wire via the insulated body. This reduces the heater's susceptibility to faults.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der erfindungsgemäßen Wärmezelle möglich. Ein besonderer Schutz vor Korrosionsprodukten wird dadurch bewerkstelligt, dass eine Hülse vorgesehen ist, die über die Brennkammerwand hinaus in die Brennkammer hineinragt. Eine zweckmäßige Abdichtung der Brennkammeröffnung wird dadurch gewährleistet, wenn die Hülse einen Bund aufweist, der die Brennkammerwand von außen hintergreift und auf diesen Bund eine Dichtung für die Halterung der Ionisationselektrode ansetzt.The measures listed in the subclaims are advantageous Further developments and improvements of the heat cell according to the invention are possible. On special protection against corrosion products is achieved by a sleeve is provided, which projects beyond the combustion chamber wall into the combustion chamber. Appropriate sealing of the combustion chamber opening is ensured if the sleeve has a collar which engages behind the combustion chamber wall from the outside and attaches a seal for holding the ionization electrode to this collar.

Zeichnungdrawing

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 ein Ausschnitt einer Wand einer Wärmezelle mit einer Befestigung für eine Ionisationselektrode gemäß einem ersten Ausführungsbeispiel und Figur 2 einen Ausschnitt einer Wand einer Wärmezelle mit einer Befestigung für eine Ionisationselektrode gemäß einem zweiten Ausführungsbeispiel.Two embodiments of the invention are shown in the drawing and in the following description explained in more detail. 1 shows a section of a Wall of a heat cell with a mounting for an ionization electrode according to one first embodiment and Figure 2 shows a section of a wall of a heat cell with an attachment for an ionization electrode according to a second Embodiment.

Ausführungsbeispieleembodiments

Die in Figur 1 teilweise dargestellte Wärmezelle für einen nicht dargestellten Brenner weist eine Brennkammer 10 mit einer Brennkammerwand 11 auf, in die eine Durchführung 13 eingebracht ist.The heat cell partially shown in Figure 1 for a burner, not shown has a combustion chamber 10 with a combustion chamber wall 11 into which one Implementation 13 is introduced.

Durch die Durchführung 13 ist beispielsweise eine Ionisationselektrode 15 geführt, die einen Elektrodendraht 16 und einen im Bereich der Durchführung den Elektrodendraht 16 umfassenden elektrisch isolierenden Körper 17 aufweist. Zur Befestigung der Ionisationselektrode 15 ist der elektrisch isolierende Körper 17 mit einer Halteplatte 20 verbunden, die wiederum mit nicht näher dargestellten Verbindungsmitteln außerhalb der Brennkammer 10 an der Brennkammerwand 11 befestigt ist.An ionization electrode 15, for example, is passed through bushing 13 one electrode wire 16 and one in the area of the leadthrough the electrode wire 16 comprising electrically insulating body 17. To attach the Ionization electrode 15 is the electrically insulating body 17 with a holding plate 20 connected, which in turn with connection means, not shown, outside the Combustion chamber 10 is attached to the combustion chamber wall 11.

In der Durchführung 13 befindet sich eine beispielsweise aus Edelstahl ausgeführte Hülse 22. Aufgrund des gewählten Materials ist die Hülse 22 korrosionsbeständig. Die Hülse 22 weist einen Bund 23 auf, der die Brennkammerwand 11 hintergreift. Die Länge der Hülse 22 ist derart gestaltet, dass sich die Hülse 22 über die Brennkammerwand 11 hinaus in die Brennkammer 10 ausdehnt. Der Durchmesser der Hülse 22 ist so dimensioniert, dass sich zwischen der Innenwand der Hülse 22 und dem elektrisch isolierenden Körper 17 ein umlaufender Spalt 24 von beispielsweise einigen Millimetern ausbildet. Durch die Hülse 22 wird die Entstehung von Korrosionsprodukten in der Durchführung 13 verhindert. Dadurch wird auch ausgeschlossen, dass Korrosionsprodukte auf den Isolierkörper 15 gelangen. Durch die sich über die Brennkammerwand 11 hinaus in die Brennkammer 10 ausdehnende Hülse 22 wird weitem verhindert, dass Korrosionsprodukte von der Brennkammerwand 11 auf die Ionisationselektrode 15 gelangen.A bushing, for example made of stainless steel, is located in the feedthrough 13 22. Because of the material selected, the sleeve 22 is corrosion-resistant. The sleeve 22 has a collar 23 which engages behind the combustion chamber wall 11. The length of the sleeve 22 is designed such that the sleeve 22 extends beyond the combustion chamber wall 11 into the Combustion chamber 10 expands. The diameter of the sleeve 22 is dimensioned such that between the inner wall of the sleeve 22 and the electrically insulating body 17 circumferential gap 24 of, for example, a few millimeters. Through the sleeve 22 prevents the formation of corrosion products in the feedthrough 13. This also rules out the possibility of corrosion products on the insulating body 15 reach. By extending into the combustion chamber 10 beyond the combustion chamber wall 11 expanding sleeve 22 is largely prevented from corrosion products from the Combustion chamber wall 11 reach the ionization electrode 15.

Zur Abdichtung der Brennkammer 10 ist zwischen der Halteplatte 20 und der Außenseite der Brennkammerwand 11 eine Dichtung 25 angeordnet. Die Dichtung 25 greift bei dem Ausführungsbeispiel gemäß Figur 1 gleichzeitig an der äußeren Ringfläche des Bundes 23 der Hülse 22 an, so dass die Dichtung 25 gleichzeitig zur Fixierung und Abdichtung der Hülse 22 dient. To seal the combustion chamber 10 is between the holding plate 20 and the outside a seal 25 is arranged on the combustion chamber wall 11. The seal 25 engages in the Embodiment according to Figure 1 simultaneously on the outer ring surface of the federal government 23 of the sleeve 22, so that the seal 25 simultaneously for fixing and sealing the sleeve 22 is used.

Gemäß dem in Figur 2 dargestellten Ausführungsbeispiel greift die Dichtung 25 an der inneren Ringfläche des Bundes 23 der Hülse 22 an. Auch hier wird durch das Befestigen der Halteplatte 20 an der Brennkammerwand 11 eine dichte Verbindung zwischen Brennkammerwand 11 und Hülse 22 realisiert.According to the embodiment shown in Figure 2, the seal 25 engages the inner annular surface of the collar 23 of the sleeve 22. Again, by fastening the holding plate 20 on the combustion chamber wall 11 a tight connection between Combustion chamber wall 11 and sleeve 22 realized.

Es ist ebenfalls denkbar, anstelle der Ionisationselektrode andere Elektroden oder Messfühler mit der beschriebenen Anordnung in einer Durchführung zu befestigen.It is also conceivable to use other electrodes or instead of the ionization electrode Fasten the sensor with the arrangement described in a bushing.
