Abstract: A gasifier for producing synthesis gas from a widely varying feedstock of waste and natural fuels, the gasifier including an induction furnace, a molten bed and slag reaction chamber mounted on top of the induction furnace, an opening fluidly connecting the molten metal and slag with the interior of the induction furnace and the inside bottom of the reaction chamber, the reaction chamber further containing a froth and off-take reaction zones above the molten metal and slag, and a lid at the top of the reaction chamber for enclosing the reaction chamber and collecting the heat and fuel gas produced therein.

Abstract: A method for producing a synthesis gas from a widely varying feedstock of waste and natural fuels including providing a reaction chamber having a bottom coupled to an induction furnace, introducing a carbonaceous fuel into a molten metal contained within the reaction chamber, continuously or intermittently supplying heat and molten metal to the reaction chamber from the induction furnace and collecting a fuel gas generated within the reaction chamber.
