Description

Die Erfindung betrifft eine Regeleinrichtung für Gasbrenner nach dem Oberbegriff des Anspruchs 1.The invention relates to a control device for gas burners according to the preamble of claim 1.

Aus der DE 199 22 226 C1 ist bereits eine Regeleinrichtung für Gasbrenner zur Bereitstellung eines Gas-/Luft-Gemischs, nämlich zum Zuführen eines Gasstroms und eines Verbrennungsluftstroms zu einem Gasbrenner, bekannt. Bei der dort offenbarten Regeleinrichtung wird ein in einer Gasleitung geführter Gasstrom mit einem in einer Verbrennungsluftleitung geführten Luftstrom gemischt, um so das dem Gasbrenner zuzuführende Gas-/Luft-Gemisch bereitzustellen, wobei diese Mischung des Gasstroms mit dem Verbrennungsluftstrom in einer Mischeinrichtung erfolgt, die dadurch bereitgestellt wird, dass die Gasleitung mit einer Gasdüse innerhalb der Verbrennungsluftleitung stromabwärts einer in die Verbrennungsluftleitung integrierten Drosselstelle mündet. Das so bereitgestellte Gas-/Luft-Gemisch kann mit einem Gebläse dem Gasbrenner zugeführt werden.From the DE 199 22 226 C1 is already a control device for gas burners for providing a gas / air mixture, namely for supplying a gas flow and a combustion air flow to a gas burner, known. In the control device disclosed therein, a gas flow guided in a gas line is mixed with an air flow guided in a combustion air line so as to provide the gas / air mixture to be supplied to the gas burner, this mixture of the gas flow with the combustion air flow taking place in a mixing device passing therethrough is provided that the gas line opens with a gas nozzle within the combustion air duct downstream of a built-in combustion air duct throttling. The thus provided gas / air mixture can be supplied to the gas burner with a blower.

Aus der DE 199 22 226 C1 ist es weiterhin bereits bekannt, über ein in die Gasleitung integriertes Gasventil den Gasstrom durch die Gasleitung mit Hilfe eines von einem elektrischen bzw. elektronischen Sensor bereitgestellten Messsignals zu regeln, um so im Gas-/Luft-Gemisch ein gewünschtes Verhältnis von Gas und Luft bereitzustellen. Hierbei greift der elektrische bzw. elektronische Sensor mit einem Messpunkt an der Gasleitung an, um den in der Gasleitung herrschenden Druck zu erfassen, wobei an einem Referenzpunkt des Sensors ein Referenzdruck herrscht. Abhängig von dem Messsignal des elektrischen bzw. elektronischen Sensors wird ein Signal zur Verstellung des Gasventils generiert.From the DE 199 22 226 C1 Furthermore, it is already known, via a gas valve integrated in the gas line, to control the gas flow through the gas line with the aid of a measuring signal provided by an electrical or electronic sensor so as to provide a desired gas / air ratio in the gas / air mixture , In this case, the electrical or electronic sensor engages with a measuring point on the gas line in order to detect the pressure prevailing in the gas line, wherein a reference pressure prevails at a reference point of the sensor. Depending on the measuring signal of the electrical or electronic sensor, a signal for adjusting the gas valve is generated.

Bei der aus diesem Stand der Technik bekannten Regeleinrichtung ist die Genauigkeit in der Regelung des Gasventils und damit in der Einstellung des Gas-/Luft-Gemischs begrenzt. Hiervon ausgehend liegt der Erfindung das Problem zu Grunde, eine neuartige Regeleinrichtung für Gasbrenner zu schaffen. Dieses Problem wird durch eine Regeleinrichtung für Gasbrenner mit den Merkmalen des Anspruchs 1 gelöst. Erfindungsgemäß ist der Messpunkt, mit welchem der Sensor an der Gasleitung angreift, unmittelbar benachbart zu einer Gasdüse positioniert, mit welcher die Gasleitung in die Mischeinrichtung mündet.In the control device known from this prior art, the accuracy in the control of the gas valve and thus in the adjustment of the gas / air mixture is limited. On this basis, the invention is based on the problem of creating a novel control device for gas burners. This problem is solved by a control device for gas burner with the features of claim 1. According to the invention, the measuring point with which the sensor acts on the gas line is positioned directly adjacent to a gas nozzle with which the gas line opens into the mixing device.

Bei der erfindungsgemäßen Regeleinrichtung ist der Messpunkt, mit welchem der Sensor an der Gasleitung angreift, unmittelbar benachbart zur Gasdüse positioniert, mit welcher die Gasleitung in die Mischeinrichtung mündet. Erfindungsgemäß wird demnach der Gasdruck unmittelbar benachbart zur Gasdüse und damit Mischeinrichtung gemessen, sodass Druckverluste in der Gasleitung, welche das Gasventil mit der Mischeinrichtung verbindet, automatisch kompensiert werden. Der elektrische bzw. elektronische Sensor kann demnach bei der erfindungsgemäßen Regeleinrichtung ein genaueres Messsignal bereitstellen, wodurch die Regelgenauigkeit für das Gasventil und damit für das Gas-/Luft-Gemisch erhöht werden kann.In the control device according to the invention, the measuring point with which the sensor acts on the gas line is positioned directly adjacent to the gas nozzle, with which the gas line opens into the mixing device. According to the invention, therefore, the gas pressure is measured immediately adjacent to the gas nozzle and thus mixing device, so that pressure losses in the gas line, which connects the gas valve with the mixing device, are automatically compensated. The electrical or electronic sensor can thus provide a more accurate measurement signal in the control device according to the invention, whereby the control accuracy for the gas valve and thus for the gas / air mixture can be increased.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Nachfolgend werden Ausführungsbeispiele der Erfindung, ohne hierauf beschränkt zu sein, anhand der Zeichnung näher erläutert. In der Zeichnung zeigt:

Fig. 1 shows a block diagram of a control device according to the invention for a gas burner, by means of which a gas / air mixture can be provided and fed to a gas burner, not shown.

Gemäß Fig. 1 umfasst die Regeleinrichtung mindestens ein in einer Gasleitung 10 positioniertes Gasventil 11, um einen Gasstrom einer Mischeinrichtung 12 zuzuführen, in welcher der über die Gasleitung 10 der Mischeinrichtung 12 zugeführte Gasstrom mit einem über eine Verbrennungsluftleitung 13 zugeführten Luftstrom gemischt werden kann. Das in der Mischeinrichtung 12 bereitgestellte Gas-/Luft-Gemisch kann über ein Gebläse 14 einem nicht-gezeigten Gasbrenner zugeführt werden.According to Fig. 1 The control device comprises at least one gas valve 11 positioned in a gas line 10 in order to supply a gas flow to a mixing device 12, in which the gas flow supplied via the gas line 10 to the mixing device 12 can be mixed with an air flow supplied via a combustion air line 13. The gas / air mixture provided in the mixing device 12 can be supplied via a blower 14 to a gas burner (not shown).

Im gezeigten Ausführungsbeispiel der Fig. 1 umfasst die Mischeinrichtung 12 eine Venturi-Düse, die in ein Gehäuse der Mischeinrichtung 12 integriert ist. Die Gasleitung 10 mündet mit einer Gasdüse 15 in die Venturi-Düse der Mischeinrichtung 12, nämlich in den Bereich der Venturi-Düse, in welchem dieselbe in etwa den engsten Strömungsquerschnitt aufweist.In the illustrated embodiment of the Fig. 1 For example, the mixing device 12 comprises a Venturi nozzle, which is integrated in a housing of the mixing device 12. The gas line 10 opens with a gas nozzle 15 in the Venturi nozzle of the mixing device 12, namely in the region of the Venturi nozzle, in which it has approximately the narrowest flow cross-section.

Gemäß Fig. 1 umfasst die Regeleinrichtung weiterhin einen elektrischen bzw. elektronischen Sensor 16, der mit einem Messpunkt 17 an der Gasleitung 10 angreift und an diesem Messpunkt 17 den in der Gasleitung 10 herrschenden Gasdruck abgreift. An einem Referenzpunkt 18 des Sensors 16 herrscht ein Referenzdruck, der vorzugsweise dem Verbrennungsluftdruck entspricht.According to Fig. 1 The control device further comprises an electrical or electronic sensor 16 which engages with a measuring point 17 on the gas line 10 and at this measuring point 17 picks up the pressure prevailing in the gas line 10 gas pressure. At a reference point 18 of the sensor 16 there is a reference pressure, which preferably corresponds to the combustion air pressure.

Der elektrische bzw. elektronische Sensor 16 stellt ein elektrisches bzw. elektronisches Messsignal 19 bereit, welches im gezeigten Ausführungsbeispiel der Fig. 1 mit einem Ausgangssignal 20 einer dem Gebläse 14 zugeordneten Auswerteeinrichtung 21 verrechnet wird. Der Auswerteeinrichtung 21 wird als Eingangssignal 22 ein Drehzahlsignal des Gebläses 14 zugeführt.The electrical or electronic sensor 16 provides an electrical or electronic measurement signal 19, which in the embodiment shown the Fig. 1 is charged with an output signal 20 of the blower 14 associated evaluation device 21. The evaluation device 21 is supplied as an input signal 22, a speed signal of the blower 14.

Ein aus dem Messsignal 19 des Sensors 16 und dem Ausgangssignal 20 der Auswerteeinrichtung 21 gebildetes Signal 23 wird in einem Regelgerät 24 verwendet, um ein Stellsignal 25 für einen Stellantrieb 26 des Gasventils 11 zu erzeugen.A signal 23 formed from the measurement signal 19 of the sensor 16 and the output signal 20 of the evaluation device 21 is used in a control device 24 in order to generate a control signal 25 for an actuator 26 of the gas valve 11.

Im Sinne der hier vorliegenden Erfindung ist der Messpunkt 17, mit welchem der elektrische bzw. elektronische Sensor 16 an der Gasleitung 10 angreift, unmittelbar benachbart zur Gasdüse 15 und damit zur Mündungsstelle der Gasleitung 10 in die Mischeinrichtung 12 positioniert. Der in der Gasleitung 10 herrschende Gasdruck wird demnach unmittelbar benachbart zur Gasdüse 15 und damit unmittelbar benachbart zum Mündungspunkt der Gasleitung 10 in die Mischeinrichtung 12 erfasst, sodass Druckverluste innerhalb der Gasleitung 10 automatisch kompensiert werden und keinen negativen Einfluss auf die erzielbare Regelgenauigkeit haben.For the purposes of the present invention, the measuring point 17, with which the electrical or electronic sensor 16 acts on the gas line 10, positioned immediately adjacent to the gas nozzle 15 and thus to the discharge point of the gas line 10 in the mixing device 12. The prevailing in the gas line 10 gas pressure is therefore detected immediately adjacent to the gas nozzle 15 and thus immediately adjacent to the mouth of the gas line 10 in the mixing device 12 so that pressure losses within the gas line 10 are automatically compensated and have no negative impact on the achievable control accuracy.

Gemäß Fig. 1 ist dem elektrischen bzw. elektronischen Sensor 16 ein Filter 27 zugeordnet, der zwischen den Sensor 16 und den Referenzpunkt 18 desselben geschaltet ist. Über den Filter 27 kann ein Verschmutzen des Sensors 16 vermieden und die Messgenauigkeit desselben und damit letztendlich die Regelgenauigkeit der Regeleinrichtung erhöht werden.According to Fig. 1 the electric or electronic sensor 16 is associated with a filter 27 which is connected between the sensor 16 and the reference point 18 thereof. Via the filter 27 contamination of the sensor 16 can be avoided and the measurement accuracy of the same and thus ultimately the control accuracy of the control device can be increased.

Wie bereits im Zusammenhang mit der Mischeinrichtung 12 ausgeführt, ist die Venturi-Düse der Mischeinrichtung 12 vorzugsweise in ein Gehäuse derselben integriert, wobei das Gehäuse und die Venturi-Düse der Mischeinrichtung 12 vorzugsweise eine monolithische Einheit ausbilden. An dieser monolithischen Einheit aus Gehäuse und Venturi-Düse der Mischeinrichtung 12 greift die Gasleitung 10 mit der Gasdüse 15 sowie das Gebläse 14 an. Vorzugsweise ist der Sensor 16 zusammen mit dem Filter 27 in das Gehäuse der Mischeinrichtung 12 integriert. Hierdurch kann eine besonders kompakte Bauform und einfache Montage der Regeleinrichtung gewährleistet werden.As already stated in connection with the mixing device 12, the venturi nozzle of the mixing device 12 is preferably integrated in a housing thereof, wherein the housing and the venturi nozzle of the mixing device 12 preferably form a monolithic unit. At this monolithic unit of housing and Venturi nozzle of the mixing device 12, the gas line 10 engages with the gas nozzle 15 and the blower 14 at. Preferably, the sensor 16 is integrated with the filter 27 in the housing of the mixing device 12. As a result, a particularly compact design and easy installation of the control device can be ensured.

Bei dem Sensor 16 handelt es sich vorzugsweise um einen Durchflussmesser bzw. ein Anemometer.The sensor 16 is preferably a flow meter or an anemometer.
