To provide a continuous scrap feeder in which generation of dioxin is reduced as mush as possible by regulating the exhaust gas temperature at the recombination temperature thereof or above.
A scrap carrier is disposed in the flue of an electric furnace coupled, at the lower section thereof, with a plurality of ducts 14 for passing exhaust gas which has preheated scrap and, at the upper section thereof, with a bypass duct 18 for passing high temperature exhaust gas. The high temperature exhaust gas bypass duct 18 is coupled with the exhaust gas ducts 14 to form a section 20 where high temperature exhaust gas is combined with exhaust gas which has preheated the scrap. Each duct is provided with an exhaust gas flow rate regulation valve 16, 19 for regulating the temperature of combined exhaust gas at 650°C or above.
