Abstract: Apparatus for the combustion of gas exiting from an electric arc furnace where the heat of combustion is used for the preheating of scraps entering the furnace wherein the apparatus has an insertion device for introducing comburent substance into a preheating chamber or loading tunnel for scrap metal where the loding tunnel has an inlet section for scrap metal, a seal section to prevent an uncontrolled entrance of air in the tunnel, a heating section and an unloading section for delivering scrap metal to the furnace. The insertion device for the comburent substance has one or more adjustable openings placed in the loading tunnel, and said apparatus comprises a device or a series of devices.

Abstract: An apparatus for the combustion of gas exiting from an electric arc furnace for the preheating of scraps entering the furnace itself foresees an insertion device of comburent substance into a preheating chamber or loading tunnel of the scrap metal having an inlet section of the scrap metal, a seal section to prevent an uncontrolled entrance of air in the tunnel, a heating section and an unloading section of the scrap metal in the furnace. Said insertion device of the comburent substance comprises one or more adjustable openings placed in the loading tunnel, and said apparatus comprises a device or a series of devices, also not equipped with autonomous movement, of mechanical seal nature placed in the insertion or inlet section of the scrap metal in the loading tunnel or preheating chamber.
