Abstract

According to one aspect of the present invention there is provided a gasifier for generating synthesis gas. The gasifier comprises a gasification chamber comprising a biomass inlet and an oxidation zone wherein the biomass inlet is arranged axially above the oxidation zone so that the biomass is moved towards the oxidation zone by means of gravity when in use. The gasifier further comprises a rotating shaft which extends within the gasification chamber.The rotating shaft comprises first biomass engaging means configured to transport engaged biomass upwards in the pyrolysis zone, away from the oxidation zone, upon rotation of the rotating shaft so as to mix the biomass.
