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. 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. A determination unit determines the state of the combustion apparatus to be inspected based on the light emission information generated by the light emission information generation unit as described above.
