A system for producing a syngas from a biomass material. The system compacts a loose biomass material to form a compacted biomass material at an entrance of a reactor tube, and then heats the compacted biomass material within the tube to form ash and a fuel gas mixture. The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof. Ingress of air into the tube is inhibited by forming a plug of the biomass material at the entrance of the tube and a plug of ash at the exit of the tube. A neutral atmospheric pressure is maintained in the reactor tube relative to pressure outside the reactor tube by monitoring and adjusting a volumetric rate of the fuel gas mixture withdrawn from the reactor tube based on pressures at the entrance and the exit of the reactor tube.

An optimized gasification/vitrification processing system having a gasification unit which converts organic materials to a hydrogen rich gas and ash in communication with a joule heated vitrification unit which converts the ash formed in the gasification unit into glass, and a plasma which converts elemental carbon and products of incomplete combustion formed in the gasification unit into a hydrogen rich gas.

The present invention discloses a gasifier and/or a gasification process that provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and/or gasification process has a char that is more energy-dense and almost devoid of moisture that affords for an additional (or char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to a evaporation and devolatilization zone. As such, the additional (or char) oxidation zone contributes to augmenting the reduction zone temperature, thereby providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

An entrained-flow gasifier reactor includes a vessel and a first liner within the vessel. The first liner extends around a reaction zone in the vessel and has an inlet end and an exit end with respect to the reaction zone. The first liner includes a drip lip at the exit end. An isolator is arranged near the drip lip. The isolator is operable to thermally isolate the drip lip from a quench zone downstream from the reaction zone such that molten slag at the drip lip remains molten.
