摘要： PROBLEM TO BE SOLVED: To effectively remove an halogen compound to a low concentration by measuring temperature of exhaust gas before the exhaust gas is subjected to a cooling treatment and controlling spray amount of an absorbent on the basis of a value of the above measurement. SOLUTION: Exhaust gas emitted from an incinerator 1 is introduced to a boiler 2. Then, the gas is cooled to a temperature of 120-300 deg.C by an exhaust gas cooling device 3 and introduced to a dust collector 4. An adsorbent is sprayed into an inlet flue of the duct collector 4 by an adsorbent feeder 7 to remove organic halogen compounds. Powdery slaked lime is sprayed to the inlet flue of the dust collector 4 by a slaked lime feeder 6 to remove acid components contained in the exhaust gas. The exhaust gas emitted from the collector 4 is discharged from the flue 5. Spray amount of the adsorbent is controlled by an adsorbent spray amount control signal 13 from an adsorbent spray amount controller 8, which receives a measured value signal 10 of an incinerator outlet thermometer 9 and an evaporation amount signal 12 of an evaporation amount measuring meter 11 to control the spray amount of the adsorbent.
