The invention relates to a method for controlling the addition of an additional fuel to a combustion process of at least one combustible material in a combustion chamber, wherein the concentration of at least one noxious substance produced by incomplete combustion is measured in the flue gas. In a second step, the amount of the additional fuel added to the combustion process is increased if the concentration of the at least one noxious substance in the flue gas exceeds a predetermined upper threshold value, or reduced if the measured concentration of the at least one noxious substance falls below a predetermined lower threshold value. The concentration is measured and the amount of the additional fuel is adjusted until the measured concentration of the at least one noxious substance in the flue gas lies in a range between the lower and the upper threshold value. |
