METHOD AND DEVICE FOR ADJUSTING AIR RATIO

摘要

The invention relates to a method for adjusting the air ratio of a fuel/air mixture, produced from a gaseous fuel and air, for operating a burner. The inventive method comprises the following steps: a) determining as the first measured value the mass flow of the fuel; b) determining as the second measured value a value for determining the Wobbe index of the fuel; c) determining as the third measured value the mass flow of the air; and d) controlling the mass flow of the air and/or of the fuel on the basis of at least two measured values in such a manner that a predetermined air ratio lambda of the fuel/air mixture is adjusted.
