Abstract
A high organic concurrent decoating kiln includes a low-oxygen zone and a high-oxygen zone. The disclosed kiln allows a gas low in free oxygen to be used in the initial stages of decoating, while a gas higher in free oxygen can be used in the final stages. The total amount of free oxygen used throughout the kiln, in particular at the upstream portion of the kiln, is kept low. Exhaust gas can be recirculated for use in a burner-fired chamber that provides the initial low-oxygen gas to the kiln.
