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.
