PURPOSE:To permit combustion control, prominent in response, by a method wherein the average value of movements during a predetermined time is obtained from the light power of flame and the integral value of a difference between an upper value and a lower value than the average value is compared with the integral value of deviation with respect to a proper O2 %, previously obtained. CONSTITUTION:An A/D converter 17 converts a light signal from a light sensor 15, converting a light power emitted from combustion flame 14 into an electric signal, into a digital signal. A combustion airflow corrector 19 integrates the electric signal from the converter 17 during a unit time to operate an average value, integrates a deviation with respect to the average value during a unit time to obtain the integral value of the deviation, receives the flow rate signal of fuel form a fuel flow meter 8 to obtain the integral value of a deviation corresponding to the optimum O2 % and compares these values to output an output for eliminating these deviations to the flow rate regulating valve 9 of combustion air. |
