Abstract
Systems and methods are disclosed for pyrolysis of waste feed material. Some systems include a main retort and a secondary retort. Syngas is produced by pyrolysis in the main retort, and is then mixed with combustion air and ignited, in some cases to produce energy. Carbon char travels to the secondary retort and is exhausted from the system through an airlock.
Claims14
A pyrolysis device comprising:
- a combustion chamber containing one or more burners configured to generate hot flue gases;
- a main retort, disposed within the combustion chamber, configured to at least partially pyrolyze a feedstock delivered to the retort, thereby generating syngas;
- a syngas relief conduit, into which syngas flows from the main retort;
- a flue gas relief duct, into which flue gas is exhausted from the combustion chamber, the flue gas relief duct being separate from the combustion chamber and having a first end in sealing fluid communication with the combustion chamber
- wherein the syngas relief duct is disposed within the flue gas relief duct and a long axis of the syngas relief duct is generally perpendicular to a horizontal plane taken through a long axis of the main retort;
- and
- a mixing chamber, into which the syngas flows from the syngas relief duct and the flue gas flows from the flue gas relief duct.
