Abstract
A flame detecting system includes a flame sensor to detect light and a calculating device, in which the calculating device includes an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of flame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times, and in which a difference in sensitivity of individual flame sensors is corrected from sensitivity parameters related to a first flame sensor and sensitivity parameters related to a second flame sensor.
