NOVELTY - The method of making a fuel gas in a gasifier including a molten metal, a molten metal froth and an off-take section to produce electrical power, comprises injecting a first solid carbonaceous fuel from a center main injection lance into molten metal and a first material consisting of a hydrocarbon, carbon dioxide, oxygen and/or steam into molten metal, molten metal froth and off-take zone, and injecting a second material consisting of a hydrocarbon, carbon dioxide, oxygen and/or steam from a top perimeter lance injection system into molten metal, molten metal froth and off-take zone.    USE - The method is useful for making a fuel gas in a gasifier including a molten metal, a molten metal froth and an off-take section to produce electrical power.    ADVANTAGE - The method is capable of efficiently, economically and environmental-friendly making the high quality fuel gas from low heat value with a low particulate level and without damaging the walls of slagging gasifiers in less consumption of energy.    DETAILED DESCRIPTION - The method of making a fuel gas in a gasifier including a molten metal, a molten metal froth and an off-take section to produce electrical power, comprises injecting a first solid carbonaceous fuel from a center main injection lance into the molten metal and a first material consisting of a first hydrocarbon, carbon dioxide, oxygen and/or steam into the molten metal, the molten metal froth and the off-take zone, injecting a second material consisting of a second hydrocarbon, carbon dioxide, oxygen and/or steam from a top perimeter lance injection system into the molten metal, the molten metal froth and the off-take zone, injecting a second solid carbonaceous fuel from a side lance injection system into the molten metal and a third material consisting of a third hydrocarbon, carbon dioxide, oxygen and/or steam into the molten metal and molten metal froth, injecting a fourth hydrocarbon from a bottom lance injection system into the molten metal, the molten metal froth and the off-take zone, creating a desired flow consisting of a counter turbulent flow and/or a cyclonic flow within the gasifier, horizontal rotational stirring the molten metal by injecting a material consisting of second, third and/or fourth materials, adjusting a stand off distance between the molten metal and the center main injection lance, between the molten metal and a top perimeter lance of the top perimeter lance injection system and between the molten metal and a side injection lance of the side lance injection system in response to a feedback, varying an injection velocity of the first solid carbonaceous fuel and the first, second and third materials, controlling a size of the molten metal froth zone by injecting a material consisting of first, second and/or third materials into the off-take zone, injecting a fifth material stream into the molten metal froth, injecting a sixth material stream into the off-take zone, injecting a seventh material stream from side injection lances into the molten metal bath and molten metal froth, injecting an eighth material stream from the bottom injection lances into the molten metal, decreasing a volume of the molten metal froth by injecting the third and sixth material streams, creating and maintaining an exothermic reaction by introducing material feed streams into the molten metal gasifier in response to the feedback, injecting carbon into the gasifier at a first rate and oxidizing the molten metal and molten metal froth and the carbon in the gasifier to carbon monoxide at a second rate, where the first and second rates are substantially the same, and oxidizing the molten metal and the molten metal froth to metal oxide at a first rate and reducing the metal oxide with carbon at a second rate. The desired flow is created from the injection of first, second, third and fourth materials into the gasifier. The first solid carbonaceous fuel consists of municipal solid waste, waxes, medical waste, glycerins, household hazardous waste, contaminated carbon, spent tires, contaminated filters, biomass, petroleum coke, bio-solids, construction materials, coal, tars, asphalt, agricultural waste and/or industrial waste. Each of the first, second, third, fourth, fifth and sixth material streams consist of a solid carbonaceous fuel, a liquid carbonaceous fuel, a gaseous carbonaceous fuel, oxygen, carbon dioxide and/or steam. A flow pattern consisting of a counter turbulent flow and/or a cyclonic flow is created by injecting second, third, fifth and sixth material streams. A desired flow direction and a desired flow velocity is created within the molten metal gasifier based upon feedback.
