Abstract

Method of controlling a burner (BR) provided with combustion chamber (CC), combustive air supply means (F) driven by a motor, at least one fuel supply duct (DTI) interceptable by a respective electric valve (EV) means, and at least one exhaust duct (DT3) for the combustion gases, comprising the following steps: - predetermining a minimum and a maximum value for the current absorbed by said motor - establishing, for a plurality of flow rate values of fuel supplied to the burner, the minimum supply voltage of said motor for ensuring a combustive air flow rate suitable for ensuring correct combustion; - supplying fuel to said burner at a predetermined flow rate; - detecting the supply voltage of said supply means and the current absorbed by said motor - checking that, for the supplied fuel flow rate, the supply voltage is greater than a predetermined threshold value and that the value of the current absorbed does not diverge from a predetermined threshold value, and - generating an output control signal when at least one of the values of voltage and current does not comply with the respective thresholds.
