A device for gasification of feedstock

Abstract

A gasification device ( 100 ) comprises an exothermic chamber ( 130 ) provided with a combustion zone ( 131 ) that is configured to perform combustion to produce process heat, a first endothermic chamber ( 110 ) adapted to perform gasification of feedstock; and a second endothermic chamber ( 120 ) adapted to subject feedstock to an endothermic break-down reaction. The gasification device ( 100 ) is configured such that the first endothermic chamber ( 110 ) uses combustion process heat to perform the gasification process. The gasification device ( 100 ) is configured such that the second endothermic chamber ( 120 ) uses combustion process heat to subject feedstock to the endothermic break-down reaction. The gasification device further comprises at least one heat-transfer rod ( 140 ) adapted to transfer combustion process heat from the combustion zone ( 131 ) of the exothermic chamber ( 130 ) to the first endothermic chamber ( 110 ) and to the second endothermic chamber ( 120 ).
