摘要： PROBLEM TO BE SOLVED: To provide a method and equipment for flue gas treatment of electric furnace, wherein concentration of DXN (dioxins) in flue gas treatment of an electric furnace is controlled so as to reach at most a target value on the discharge side of a dust collector by optimally operating respective equipment in accordance with DXN concentration. SOLUTION: In the flue gas treatment, flue gas 6 directly drafted from the electric furnace 1 is merged into flue gas 9 of atmosphere gas drafted from a building. Dioxins in the merged flue gas are removed by the dust collector 10. Concentration of DXN at the discharge port of the dust collector is estimated to control the flue gas flow-rate on the basis of estimated values of DXN concentration according to operation times of the furnace 1, measurement results of temperatures and flow rates of respective flow gases, and the relation between temperature in the dust collector and the rate of DXN removal.
