NOVELTY - Two-stage plasma conversion of waste having organic and inorganic components into fuel gas comprises vitrifying or melting the inorganic components of the waste and partially gasifying the organic components in the first state, and completing the gasification of the organic components to convert them into fuel gas in the second stage.    USE - For two-stage plasma converting of waste having organic and inorganic components into fuel gas. The fuel gas is used in gas engine or turbine for the production of electricity, gas burner for the production of steam, or in chemical synthesis reactions.    ADVANTAGE - The invention recovers energy from waste in a clean and efficient way.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a conversion apparatus for converting waste having organic and inorganic components into fuel gas comprising primary gasifier having refractory lined and enclosed plasma arc furnace provided with graphite electrode(s), inlet(s) for feeding waste into the furnace, mechanism for feeding air, oxygen, and/or steam in metered amounts into the furnace, and gas take off port for primary synthesis produced in the primary gasifier; and secondary gasifier where primary synthesis gas is fed. The primary gasifier is adapted to maintain layers of molten metal and molten slag at the bottom of the furnace and on top of the molten slag a layer of partially treated waste on top where fresh waste is fed. The graphite electrode(s) is positioned to generate a plasma arc t the molten slag present in the furnace during the operation. The secondary gasifier is equipped with a plasma-torch fired eductor that ensures that the primary synthesis gas entering from the primary gasifier is exposed to a high temperature, mechanism for supplying metered amounts of air, oxygen, and/or steam into the eductor, and outlet provided on the chamber for the fuel gas resulting from the operation.    DESCRIPTION OF DRAWING(S) - The figure is a diagrammatic representation of the two-stage plasma process for converting waste into fuel gas.
