Provided is a dual fluidized bed gasifier. The dual fluidized bed gasifier comprises: a combustion unit for performing a combustion reaction after receiving air from a lower part; a cyclone for separating products of the combustion reaction of the combustion unit, and collecting a fluidization medium; a gasification unit for performing a gasification reaction by receiving heat by the fluidization medium from a fuel, an oxidizer, and the combustion unit; and a pipe of which an upper part and a lower part are open inside the gasification unit. The dual fluidized bed gasifier has excellent gasification efficiency by improving contact efficiency between an oxidizer and a fluidization medium, and has effects in using various fuels as a fuel for gasification of the dual fluidized bed gasifier. |
