Biomass gasification apparatus

Abstract

A compact biomass gasification apparatus is capable of gasifying a wide variety of biomass materials, without regard to their size and/or the water content of those materials, and also capable of substantially removing the tar component generated in a gasification process. A biomass gasification apparatus primarily includes an externally heated rotary kiln-type thermal cracking unit (2) indirectly heating and thermally cracking a biomass material to generate a tar-containing pyrolysis gas and char from the biomass material, and a gasification unit (3) receiving the tar-containing pyrolysis gas and char from the thermal cracking unit (2) and thermally cracking the tar component in the pyrolysis gas and gasifying the char by an oxidation gas being introduced therein.
