A method for producing fuel gas from carbonaceous solid feedstocks, comprising the steps of: - charging the feedstocks into at least one entrained flow degasification reactor, and at least partially degassing the feedstocks while producing a reaction gas and solid residue, in particular conversion coke; - discharging the solid residue, charging at least a partial amount thereof into a coal gasification reactor, and gasifying the solid residue while producing a reaction gas and ashes or slag, wherein oxygen and/or steam is nozzled into the coal gasification reactor for adjusting the combustion stoichiometry; - injecting the reaction gases from the coal gasification reactor into the at least one entrained flow degasification reactor, wherein the reaction gases are used as heat transfer media for heating the at least one entrained flow degasification reactor; - injecting at least a portion of the reaction gases from the at least one entrained flow degasification reactor into a reforming reactor, and cracking the tar fraction of the reaction gas in the reforming reactor to obtain fuel gas, said cracking in the reforming reactor being performed at temperatures of 750-1000°C, preferably by using an induction heater, in particular a graphite induction heater, and by using catalysts such as zeolite or activated minerals as calcites, dolomites and/or calcium aluminates, characterized in that the feedstocks are charged into a first entrained flow degasification reactor and subjected to a first degasification, and the solid residue from the first degasification is at least partially fed to a second entrained flow degasification reactor and subjected to a second degasification, wherein the solid residue of the second degasification is at least partially charged into the coal gasification reactor and the reaction gas of the second degasification is at least partially conducted into the reforming reactor. - charging the feedstocks into at least one entrained flow degasification reactor, and at least partially degassing the feedstocks while producing a reaction gas and solid residue, in particular conversion coke; - discharging the solid residue, charging at least a partial amount thereof into a coal gasification reactor, and gasifying the solid residue while producing a reaction gas and ashes or slag, wherein oxygen and/or steam is nozzled into the coal gasification reactor for adjusting the combustion stoichiometry; - injecting the reaction gases from the coal gasification reactor into the at least one entrained flow degasification reactor, wherein the reaction gases are used as heat transfer media for heating the at least one entrained flow degasification reactor; - injecting at least a portion of the reaction gases from the at least one entrained flow degasification reactor into a reforming reactor, and cracking the tar fraction of the reaction gas in the reforming reactor to obtain fuel gas, said cracking in the reforming reactor being performed at temperatures of 750-1000°C, preferably by using an induction heater, in particular a graphite induction heater, and by using catalysts such as zeolite or activated minerals as calcites, dolomites and/or calcium aluminates,
