ABSTRACT:
An aluminum remelting furnace for recycling scrap. In order to prevent atmospheric dispersion of toxic substances from the combustion of aluminum scrap contaminants, the furnace includes a loading chamber positioned on the upper wall of the furnace which is provided with a lower door and an upper door. During loading, the lower door is opened while the upper door remains closed to prevent the escape of the contaminant substances which remained enclosed within the loading chamber. After closing the lower door, the contaminant substances are fed to a post-combustion chamber and then to a gas treatment and purification system.
