  • the invention relates to a method for operating a gas burner according to the preamble of claim 1.
  • a gas burner is supplied with a gas-combustion air mixture to burn the gas of the gas-combustion air mixture in the gas burner.
  • a flame is formed in the gas burner, wherein it is already known from the prior art to check the presence of a flame in the gas burner on the basis of an ionization current provided by an ionization sensor. This can be ensured that, if no flame is formed in spite of supplying a gas-combustion air mixture to the gas burner in the gas burner, that further supply of the gas combustion air mixture to the gas burner can be prevented.
  • combustion sensors wherein such a combustion sensor can be configured as an oxygen sensor or as a carbon monoxide sensor or carbon dioxide sensor.
  • Such combustion sensors are expensive. There is therefore a need for a method for operating a gas burner, by means of which, even without such expensive combustion sensors, it can be determined whether there is stable or unstable combustion in the gas burner.
  • the invention is based on the problem to provide a novel method for operating a gas burner.
  • This problem is solved by a method for operating a gas burner with the features of claim 1. With the help of the ionisationsstrom is monitored whether stable or unstable combustion is present in the gas burner.

Abstract

L'invention concerne un procédé d'utilisation d'un brûleur à gaz. Selon le procédé, un mélange gaz/air de combustion est introduit dans le brûleur à gaz pour la combustion dans le brûleur à gaz, et un capteur à ionisation fournissant un courant d'ionisation permet de contrôler de préférence une flamme du brûleur à gaz. Selon l'invention, le courant d'ionisation permet de contrôler si la combustion dans le brûleur à gaz est stable ou instable.
