Flame monitor

Abstract

To grasp a state of a combustion apparatus based on a flame state of a burner, a discharge number measurement unit measures the number of discharges of a flame sensor per unit time, and a light emission information generation unit generates, as light emission information, information obtained based on a value obtained by dividing a total (accumulation) of the number of discharges per unit time measured by the discharge number measurement unit by a total measurement time, and a display unit displays the light emission information generated by the light emission information generation unit. Since the light emission information corresponds to a combustion amount, a change in a combustion state is capable of being grasped more finely by confirming a change in the light emission information displayed on the display unit, and a fine abnormality in a combustion apparatus is capable of being detected.
