The invention provides a system designed for the complete conversion of carbonaceous feedstock into syngas and slag. The system comprises a primary chamber for the volatilization of feedstock generating a primary chamber gas (an offgas); a secondary chamber for the further conversion of processed feedstock to a secondary chamber gas (a syngas) and a residue; a gas-reformulating zone for processing gas generated within one or more of the chambers; and a melting chamber for vitrifying residue. The primary chamber comprises direct or indirect feedstock additive capabilities in order to adjust the carbon content of the feedstock. The system also comprises a control system for use with the gasification system to monitor and regulate the different stages of the process to ensure the efficient and complete conversion of the carbonaceous feedstock into a syngas product.

1. A multi-chamber system for converting carbonaceous feedstock to syngas and slag, comprising: one or more primary chambers for conversion of carbonaceous feedstock to a processed feedstock/char and a primary chamber gas, wherein each primary chamber comprises a feedstock inlet, a first air input means, an optional process additive input, a primary chamber gas outlet, and a processed feedstock/char outlet;one or more secondary chambers for conversion of processed feedstock/char to a residue and a secondary chamber gas, wherein each secondary chamber comprises a processed feedstock/char inlet for receiving processed feedstock/char from at least one of said primary chambers, a second air input means, an optional process additive input, a secondary chamber gas outlet, a residue outlet and an impedance mechanism configured to partially or intermittently occlude the residue outlet, thereby limiting or regulating the flow of material out of the secondary chamber;one or more gas reformulating chambers each comprising a gas reformulating zone, in fluid communication with at least one of said primary chamber and secondary chamber gas outlets for conversion of said primary chamber gas and/or said secondary chamber gas received therefrom to a processed syngas, comprising an optional process additive input, a syngas outlet, and one or more sources of reformulating heat;one or more melting chambers for converting the residue from said secondary chambers to slag, wherein each said melting chamber comprises a residue inlet in communication with the residue outlet of said secondary chambers, one or more sources of melting heat, and a slag outlet; anda control system to regulate the operation of the system. 2. The system of claim 1, wherein the impedance mechanism is a dome shaped barrier. 3. The system of claim 1, wherein at least one of said sources of reformulating heat is a plasma system. 4. The system of claim 1, wherein at least one of said sources of reformulating heat is a hydrogen burner. 5. The system of claim 1, wherein said feedstock inlet comprises a primary and secondary feedstock inlet, wherein the secondary feedstock inlet is used for input of feedstock additives. 6. The system of claim 1, wherein at least one of said first input means and second air input means receive heated air from a syngas-to-air heat exchanger. 7. The system of claim 1, wherein the first air input means and the second air input means are heated air inlets. 8. The system of claim 1, wherein at least one of said primary and secondary chambers further comprises means for controlling the residence time thereof, wherein the means for controlling the residence time comprises a controllable solids removal means selected from the group consisting of a rotating arm, a pusher ram, and a set of screws. 9. The system of claim 1, wherein at least one of said sources of melting heat is a plasma system, a gas burner or a Joule heating element. 10. The system according to claim 1, wherein at least one of said primary chambers comprise one or more lateral transfer units for use as a controllable solids removal means. 11. The system according to claim 1, wherein the control system comprises: one or more sensing elements for monitoring of and obtaining data regarding operating parameters within the system; andone or more response elements for adjusting operating conditions within the system; wherein the sensing elements and the response elements are integrated within the system, and wherein the response elements adjust the operating conditions within the system according to the data obtained from the sensing elements. 12. A process for converting a carbonaceous feedstock to a processed syngas using the system of claim 1, comprising the steps of: inputting carbonaceous feedstock into one or more primary chambers;inputting heated air and optionally a process additive into the one or more primary chambers to convert the carbonaceous feedstock to processed feedstock and a primary chamber gas;transferring the processed feedstock to one or more secondary chambers;inputting heated air and optionally a process additive into the one or more secondary chambers to convert the processed feedstock to a secondary chamber gas;transferring the primary chamber gas from the one or more primary chambers and the secondary chamber gas from the one or more secondary chambers into the gas reformulating zone;applying heat from one or more sources of reformulating heat to convert the primary and/or secondary chamber(s) gas to the processed syngas.
