Abstract: A method and apparatus for preheating scrap metal within pure gases discharged from a metallurgical vessel. The method comprises the steps of burning the gases in a combustion chamber to remove impurities therefrom, conducting a first portion of the combustion products to a container of scrap metal, contacting the scrap metal with the combustion products for preheating the scrap metal whereby additional impurities are generated, washing in a wet scrubber the mixture of combustion products and additional impurities, mixing the scrubbed combustion products and additional impurities with a second portion of the combustion products from the combustion chamber, and removing particulates from the mixture.
