1. A furnace monitoring device comprising:
at least one memory storing instructions;
at least one processor configured to execute the instructions;
an imaging unit configured to capture an image of combustion ash adhering to a monitoring position in a furnace; and
a monitoring panel configured to output an alert for the combustion ash,
wherein the at least one processor is configured to:
store a deposited amount table indicating a relationship between a luminance value of a monitoring image and an amount of deposited combustion ash in advance,
acquire a luminance value of a monitoring image which is output from the imaging unit,
acquire an amount of deposited combustion ash corresponding to the luminance value acquired with reference to the deposited amount table using the luminance value required, and
make the monitoring panel output the alert on the basis of the amount of deposited combustion ash acquired.
