Abstract

Die Erfindung betrifft ein Verfahren zur Erkennung einer Gasfamilie unter Nutzung eines Gebläses bei einer Gasbrennvorrichtung mit den folgenden Verfahrensschritten Messen eines dem Gebläse zugeführten Luftmassenstroms mL1 mit einem Luftmassenmesser sowie einer ersten Gebläsedrehzahl zu einem vordefinierten Zeitpunkt, Betrieb des Gebläses bei konstantem Luftmassenstrom mL1, Zuführen von Gas, in Strömungsrichtung nach dem Luftmassenmesser, in den Luftmassenstrom mL1, so dass das Gebläse ein Gas-Luft-Gemisch fördert, wodurch sich der Luftmassenstrom von mL1 zu mL2 ändert, Messen der Luftmassenstroms mL2 mit dem Luftmassenmesser sowie einer aus der Gaszuführung resultierenden zweiten Gebläsedrehzahl, Vergleich der ersten Gebläsedrehzahl mit der zweiten Gebläsedrehzahl sowie eine Gasbrennvorrichtung zum Ausführen des Verfahrens.

Figure imgaf001
The invention relates to a method for detecting a gas family using a blower in a gas burner with the following process steps measuring a blower supplied air mass flow mL1 with an air mass meter and a first blower speed at a predefined time, operation of the blower at constant air mass flow mL1, supplying gas , in the direction of flow after the air mass meter, in the air mass flow mL1, so that the fan promotes a gas-air mixture, which changes the air mass flow from mL1 to mL2, measuring the air mass flow mL2 with the air mass meter and a second fan speed resulting from the gas supply, Comparing the first fan speed with the second fan speed and a gas burner apparatus for carrying out the method.
