Abstract
A primary duct is provided for supplying hot waste gas from an electric furnace to a preheater bucket charged with scrap. A preheating waste gas duct connected to the bucket is branched into a discharge duct for releasing preheating waste gas from the apparatus and a recycling duct for recycling preheating waste gas to the primary duct. In the vicinity of the junction of the primary duct and the recycling duct, an air inlet is formed for supplying air into the primary duct for burning the preheating waste gas.
