Summary:PROBLEM TO BE SOLVED: To suppress the overshooting of the internal temperature of the furnace as much as possible and prevent the high-temperature interruption and shutdown of a deodorizing furnace, by automatically raising the set internal temperature value of the furnace from the lowest set value to a set value for normal operation at the saturation of temperature rise. SOLUTION: When baking finish becomes necessary from a state where no baking finish is required, a sequence controller 50 receives a baking finish command from a computer 60 for operation. The controller 50 instructs a differential operator 40 to start operation. Then an object to be incinerated is taken in a deodorizing furnace and the internal temperature of the furnace starts to overshoot. The operator 40 grasps the saturation point of the overshooting internal temperature by computing the overshooting state and outputs the value of the saturation point to the sequence controller 50. The controller 50 automatically changes the set value 30 of a regulator 14 for regulating the internal temperature of the deodorizing furnace to a set temperature value for normal operation from the saturated state of the overshooting temperature received from the operator 40 and the baking finish signal received from the computer 60.
