Abstract (en)

A method for controlling a fuel-oxidizer mixture in a premix gas burner (100), comprising the following steps performed by a processor: receiving (F1, F2) a flame signal (401, 402) representing the presence of a flame deriving from the combustion of a fuel belonging to a first predetermined type or a second predetermined type inside a combustion cell (TC) of the burner (100); accessing (F3', F3") fuel data (403), representing the fact that the gas fuel belongs to the first type or the second type; generating (F6) drive signals (501) to control a gas flow regulating valve (7) that supplies gas to the burner and to control a rotation speed of a fan (9) configured to take in oxidative air; sending (F7) the drive signals (501) to the gas flow regulating valve (7) and to a motor connected to the fan (9). The processor has access to a memory unit containing first regulation data (R1) and second regulation data (R2), different from the first regulation data (R1) and is programmed to generate the drive signals (501) based on the first regulation data (R1) or, alternatively, on the second regulation data (R2), depending on the fuel data (403).
