Abstract
A tar removal device removes tar contained in a gasification gas () generated in a gasification furnace of a two-towered gasifier having a combustion furnace () heating a heating medium (A) and the gasification furnace () introducing the heating medium (A) heated in the combustion furnace to perform gasification of a starting material (). The tar removal device includes a tar separation unit () that introduces the gasification gas from the gasification furnace to fluidize the circulating particles (B) so as to adhere the tar in the gasification gas to the circulating particles, and a tar combustion unit () that introduces the circulating particles to which the tar is adhered at the tar separation unit, fluidizes the circulating particles using air () so as to burn the tar adhered to the circulating particles, supplies the combustion gas () in which the tar is burnt to the combustion furnace as a gas for combustion, and returns the circulating particles from which the tar is burnt and removed to the combustion furnace.
