Abstract: A downdraft gasifier is disclosed. The gasifier includes a biomass section that accepts and stirs raw biomass materials, a pyrolysis and tar cracking section having an inner cylinder for receiving biomass and an outer surrounding cylinder for gases from the biomass, and a char gasification section for receiving biomass and gases from the pyrolysis and tar cracking section. The char gasification section provides a grating and scraper for passing gases and ash and retaining biomass for char gasification on the grate.

Abstract: A downdraft gasifier is disclosed. The gasifier has a biomass feeding unit, a combustion chamber, and a separator unit. The biomass feeding unit accepts raw biomass materials and selectively feeds the materials into the combustion chamber. The combustion chamber provides means to induce pyrolysis, tar cracking, and char gasification of the raw biomass materials to produce gases and ash. The separator unit accepts the gases and ash from the combustion chamber and separates the gases from the ash.
