Abstract

For controlling the secondary air supply of a burner with a primary combustion section (2) and a downstream secondary combustion section (3) following the secondary air supply, the electrical conductivity of the flame or of the combustion gases is detected in each case via a measuring device (12 or 13) on the one hand in the region of the primary combustion section (2) and on the other hand in the region of the secondary combustion section (3), the measured guide value in the region of the secondary combustion section (3) being supplied to a control device (11) as the actual value for a control adjustment, the desired value of which is selected, depending upon the detected guide value in the region of the primary combustion section (2), from a stored correlation between these guide values and the desired values for the secondary combustion section (3).
