Claims (1)

The incinerator is provided with an incineration treatment zone for incineration of garbage, primary combustion air supply means for supplying primary combustion air below the incineration treatment zone, and secondary combustion air in the combustion space above the incineration treatment zone Secondary combustion air supply means for controlling the secondary combustion air supply means by controlling the secondary combustion air supply means based on the measured value of the oxygen concentration sensor for detecting the oxygen concentration of the exhaust gas discharged from the incinerator. A garbage incinerator equipped with a control means for adjusting the supply amount,
A first sensing unit that measures the amount of air per unit time supplied by the primary combustion air supply means, and a second sensor that measures the amount of air per unit time supplied into the furnace by the secondary combustion air supply means With a sensing unit,
The control means sets the target supply amount of the secondary combustion air so that the oxygen concentration value of the exhaust gas is maintained at a preset target value, and measures the target supply amount by the second sensing. A feedback control unit for controlling the secondary combustion air supply means is provided, and the target supply amount of the secondary combustion air set based on the control by the feedback control unit is compared with the air amount measured by the first sensing unit. when used below is a pre-set ratio, the target air amount the preset ratios above and so as the secondary combustion air are garbage incinerator which comprises a priority control unit for setting a target supply amount of the instead of .
