Abstract
A method for regulating the combustible mixture such as air/gas, air/methane gas or the like fed to a burner, the method including measuring a flame signal correlated with the composition of the mixture fed by feed members controlled by a combustion controller arranged to regulate the combustion on the basis of the flame signal. During burner operation the mixture feed conditions are modified within a narrow time interval to obtain a flame signal variation; a ratio between values of this the flame signal at the end and at the beginning of the interval is compared with a predetermined reference value; and, on the basis of the deviation of this ratio from the reference value, the flame set point is regulated, as consequently is the air or gas of the mixture if this is rendered necessary.
