Abstract

Apparatus and methods for debinding articles. The apparatus and methods may transform binder from furnace exhaust before the exhaust is discharged to the atmosphere. The apparatus may include a furnace retort and a reactor. The furnace retort may be configured to: exclude ambient air; and receive a carrier gas. The reactor may be configured to: receive from the retort (a) the carrier gas and (b) material removed in the retort from the article; and combust, at a temperature no greater than 750° C., the material. The material may be decomposed binder. The material may be hydrocarbon from binder that is pyrolyzed in the retort. The carrier gas may include gas that is nonflammable gas.
