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: a primary chamber for conversion of carbonaceous feedstock to a processed feedstock/char and a primary chamber gas, wherein the 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;a secondary chamber for conversion of processed feedstock/char to a residue and a secondary chamber gas, wherein the secondary chamber comprises a processed feedstock/char inlet for receiving processed feedstock/char from said primary chamber, a second air input means, an optional process additive input, a secondary chamber gas outlet, a residue outlet and an impedance mechanism comprising a brick grate configured to limit or regulate the flow of material out of the secondary chamber;a gas reformulating chamber comprising gas reformulating zone, in fluid communication with at least one of said primary chamber gas outlet and secondary chamber gas outlet 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 a source of reformulating heat;a melting chamber for converting the residue from said secondary chamber to slag, wherein 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 at least one of said sources of reformulating heat is a plasma system. 3. The system of claim 1, wherein at least one of said sources of reformulating heat is a hydrogen burner. 4. 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. 5. The system of claim 1, wherein at least one of said first air input means and second air input means receive heated air from a syngas-to-air heat exchanger. 6. The system of claim 1, wherein the first air input means and the second air input means are heated air inlets. 7. The system of claim 1, wherein said primary chamber 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. 8. 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. 9. 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. 10. 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. 11. The system according to claim 1, wherein the brick grate is mounted at the bottom of the secondary chamber.
