Process and apparatus for the treatment of contaminated fumes from a furnace for melting contaminated scrap metal, in particular remelting and recycling of waste aluminium metal, the furnace including at least one melting chamber (1) with burners for heating the chamber (1) and melting the metal. The fumes from the melting chamber are led to a secondary chamber (2), including a mixing se ction (4) and incineration section (5), where the fumes are respectively mixed and treated under controlled temperature, oxygen content and moisture before being passed to a regenerator (6), further to a filter system (8) and finally to a stack (10). In a preferred embodyment ambient air is preheated by the regenerator (6) before being passed partly to burners (9) for the melting chamber (1) and an air heater (7) for the heating and supply of air to the secondary chamber (2) |
