PROBLEM TO BE SOLVED: To stably operate a fluidized bed furnace by easily detecting deterioration of a bed material classifying device of a fluidized bed pyrolytic furnace. SOLUTION: In this operating method of pyrolytic processing equipment comprising the pyrolytic furnace having a fluidized bed for fluidizing a bed material, a temperature measuring means for measuring a temperature of the fluidized bed, the bed material classifying device for classifying the bed material extracted from the pyrolytic furnace, and a bed material circulating passage for circulating the bed material classified by the bed material classifying device to the fluidized bed, temperature of several parts of the fluidized bed are measured by the temperature measuring means, temperature difference of the parts is calculated on the basis of the measured temperatures, and the deterioration of the bed material classifying device is detected while applying the temperature difference as a barometer.
