Abstract
A method for controlling a fuel supply to a plurality of burners of a burner group includes determining a temperature in the burner group as a control variable. The fuel supply to the burners of the burner group is specified in dependence on a control deviation of the temperature determined in the burner group to a specified setpoint temperature. The fuel supply is a common mean fuel supply that is specified for all of the burners of the burner group by a temperature master controller. The fuel supply is corrected for each of the burners or burner subgroups of the burner group. Each of the burners or the burner subgroups have a fuel supply slave controller. The fuel supply slave controllers use at least, one disturbance variable associated to the respective burner or the respective burner subgroup so as to perform the correcting.
