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.

Dependent claims

An inspection device comprising:

a flame sensor configured to detect ultraviolet rays generated from a flame generated by a combustion apparatus;
an application voltage generation unit configured to periodically apply a drive voltage to an electrode of the flame sensor;
a discharge number measurement unit configured to measure the number of discharges of the flame sensor per unit time;
a light emission information generation unit configured to generate, as light emission information, information obtained based on a value obtained by dividing a total of the number of discharges per unit time measured by the discharge number measurement unit by a total measurement time;
and
a determination unit configured to determine a state of the combustion apparatus based on the light emission information.
