Abstract:
A method for gasifying solid organic materials to produce a gaseous effluent and solid residue, said method comprising the steps of:providing a source of supply of solid organic materials;providing a primary oxidation chamber having a converging upper portion and a bottom portion;introducing solid organic materials from said source of supply into said primary oxidation chamber upwardly from said bottom portion of said primary oxidation chamber to provide a mass of said solid organic materials in said primary oxidation chamber;heating said mass of solid organic materials in said primary oxidation chamber;adding an oxidant to said primary oxidation chamber to gasify said heated mass of solid organic materials in said primary oxidation chamber and to initiate a flow of gaseous effluent within said primary oxidation chamber;establishing a gaseous effluent flow path within said primary oxidation chamber whereby a portion of said gaseous effluent repeatedly flows in a recirculating upward and downward direction through said heated solid organic materials to enhance continuous oxidation of said solid organic materials, and a further portion of said gaseous effluent flow is advanced in a direction outward from said primary oxidation chamber; andtransferring said solid residue out of said primary oxidation chamber.
