Abstract
Apparatuses, systems, tar crackers, and methods for breaking down vaporized tars in a syngas stream are described. An example system may include a gasifier comprising a combustion chamber configured to, during a startup operation, receive heated air at a first port near a bottom of the combustion chamber and to support combustion of a column of biomass feedstock in an upward direction within the combustion chamber. The combustion chamber may be further configured to receive, during normal operation, air at a second port near a top of the combustion chamber to support gasification of the column of biomass feedstock in a downward direction within the combustion chamber to provide syngas from the first port near the bottom of the combustion chamber.
