GASIFICATION REACTING APPARATUS USING BIOMASS

The present invention relates to a gasification reaction apparatus using biomass capable of enhancing energy efficiency, wherein a reactor is provided with first and second air supply assemblies and a heat-exchange unit, the first and second air supply assemblies allow an amount of air supplied to an oxidation area to be selectively adjusted according to a state and a kind of biomass introduced into the reactor, and the heat-exchange unit allows high sensible heat of synthetic gas discharged from the reactor to be reused for heating air required for a gasification process, thereby not only allowing a selective operation according to a state and a kind of the introduced biomass and an increase in production of the synthetic gas, but also recovering sensible heat of discharged synthetic gas to raise a temperature of air supplied as an oxidizing agent and re-introduce the air into the gasification process.
