Abstract

A plant for the processing of exhaust gases of an electric melting furnace for steel is disclosed, which allows to improve the cleaning of heavy-metal-containing exhaust gases from electric arc furnaces for steel production from scrap, which allows to decrease the energy use for capturing waste from the exhaust gases, which avoids the odor molestation by the waste gases generated in connection with an electric melt furnace operation during the preheating and for making useful the exhaust gases for the smelting under incorporation of the drying of oil-containing roll sinter muds, where simultaneously the oil-content of these roll sinter muds is used for saving of electric arc melting energy.
