Scrap dryer and/or scrap preheater

A device (1) for drying and/or preheating scrap, comprising:

• a receiving container (3);
• a scrap basket (7) arranged in the receiving container (3), the scrap basket (7) having a gas-permeable bottom area (9),
• a process gas inlet line (6) that extends through a wall (4) of the receiving container (3) and via which a process gas can be introduced into the receiving container (3);
• an injector nozzle (19) arranged coaxially within the process gas inlet line (6);
• a cover element (25) or a hood (23) fluidically connected to a process gas outlet line (24);
• and
• an outlet line blower (31) arranged in the process gas outlet line (24),
• wherein a cooling gas can be introduced into the process gas via the injector nozzle (19), and
• wherein a temperature of the process gas upstream of the injector nozzle (19) is in a range from 200 to 1600° C., and
• wherein a temperature of the process gas downstream of the injector nozzle (19) is lower than 600° C., and
• wherein the process gas flowing through the scrap basket (7) and ambient air are sucked off via the cover element (25) or the hood (23) through the process gas outlet line (24) by the outlet line blower (31).
