A system and method for providing an integrated indirectly fired reactor and steam generator are disclosed. According to one embodiment, the reactor comprises an indirect heating zone heating water and generating steam, a mixing zone mixing feedstock and the steam and providing a mixture of the feedstock and the steam, and a reaction zone comprising a first reactor and a second reactor. The first reactor converts the mixture to a first syngas at a first temperature. The second reactor converts the first syngas to a second syngas at a second temperature, the second temperature being higher than the first temperature.

1. A reactor comprising: an indirect heating zone for combusting syngas with air to generate hot combustion gases, the hot combustion gases for heating a reaction zone, the indirect heating zone having a heat exchanger for generating steam by using the hot combustion gases;a mixing zone for mixing feedstock and the steam and for providing a mixture of the feedstock and the steam; andthe reaction zone for providing oxygen-free gasification, the reaction zone comprising a first reactor for converting the mixture to a first syngas at a first temperature; anda second reactor for converting the first syngas to a second syngas at a second temperature, the second temperature being higher than the first temperature,wherein the of combustion gases remain separated from the steam, the feedstock, the mixture, the first syngas, and the second syngas. 2. The reactor of claim 1, wherein the reaction zone is surrounded by the heating zone. 3. The reactor of claim 1, wherein the reactor is one of a cylindrical shape or a rectangular shape. 4. The reactor of claim 1, wherein the first reactor and the second reactor are vertically disposed next to each other and are separated by a dividing wall. 5. The reactor of claim 1, further comprising a plurality of thermal conductors extending from the heating zone to the first reactor and the second reactor. 6. The reactor of claim 1, wherein the heating zone comprises a first heating zone disposed adjacent to the first reactor and a second heating zone disposed adjacent to the second reactor. 7. The reactor of claim 1, wherein the mixing zone comprises a feed injection zone and the feedstock is gravity-fed via the feed injection zone. 8. The reactor of claim 1, the feedstock is mixed with CO2. 9. The reactor of claim 1, wherein the feedstock is mixed with the steam in the mixing zone in a cross-flow pattern. 10. The reactor of claim 1, wherein the steam is provided in the form of jets and creates turbulence in mixing zone. 11. The reactor of claim 1 further comprising a recovery zone, wherein the recovery zone is compartmentalized to collect residual solid, liquid, or gas generated in the reaction zone. 12. The reactor of claim 11, wherein the recovery zone comprises an inner compartment and an outer compartment, and wherein air in the outer compartment is evacuated prior to opening the inner compartment to prevent the air from entering the reaction zone. 13. The reactor of claim 1 further comprising a refractory brick lining surrounding the reactor. 14. The reactor of claim 13, further comprising a thermal radiation shield disposed between the refractory brick lining and the heating zone. 15. The reactor of claim 1, wherein the second syngas comprises CO2. 16. The reactor of claim 15, wherein the CO2 is fed for capture and sequestration. 17. The reactor of claim 15, wherein the second syngas further comprises hydrogen sulfide, and wherein the hydrogen sulfide is extracted from the second syngas. 18. The reactor of claim 17, wherein the second syngas drives a turbine for power generation. 19. The reactor of claim 1, wherein the feedstock is biomass. 20. The reactor of claim 18, further comprising a compressor and an alcohol synthesis reactor. 21. The reactor of claim 18, further comprising a distiller for producing ethanol from the syngas. 22. The reactor of claim 1, wherein the second syngas is fed to a synthesis reactor to generate synthetic fuels.
