FIXED-BED BIOMASS GASIFIER FORMED WITH SWIRLING GAS-INJECTION PORT

摘要

The present invention relates to a fixed-bed biomass gasifier formed with a swirling gas-injection port. More particularly, a gasification agent is supplied in a swirling manner by forming the swirling gas injection port on the lower side of a gasification reactor in which a gasification reaction is carried out by supplying lignocellulosic biomass, and thus accelerates gasification by increasing the duration of contact between the swirling gasification agent and a pyrolysis layer. Also, a catalyst chamber is disposed in the upper portion thereof, at which an outlet is formed, so as to convert the tar contained in discharged synthetic gas into additional synthetic gas.
