Tyer carburetion process

Abstract

A means for improving prior art combined cycle combustor and/or gasifiers and/or plural thermodynamic cycle gasification systems by introducing and utilizing an auger for the continuous feeding, agitation, tumbling, advancement and discharge of heterogenous carbonaceous fuel. In addition to the aforementioned improvement, I have included provisions for Fontana's water gas shift reaction utilizing refectory embedded down-tubes that convey steam and oxygen into and through the chambers fluidized bed.

1 . A gasifier system, comprising:
 a primary gasifier having an inlet for receiving gasifiable materials into its interior and outlets for discharging a flue gas discharge stream and char remaining after initial gasification of said gasifiable materials; and   a secondary gasifier receiving char from said primary gasifier, said secondary gasifier comprising
 an elongated horizontally disposed stationary secondary gasifier chamber, said chamber having a first end with an inlet for receiving said char into its interior and a second end with outlets for discharging an enriched water gas stream produced by steam treatment of said char within the secondary gasifier chamber and ash remaining after said treatment, the horizontal position of said elongated stationary chamber defining an upper and a lower side, and 
 a rotatable screw conveyor extending through said secondary gasifier chamber's interior from proximate said first end to proximate said second end for moving said char therethrough, said screw conveyor comprising an axial member having two ends with a plurality of spiral flights forming a continuous helix around said axial member. 
   
     
     
         2 . The gasifier system of  claim 1 , wherein said primary gasifier is comprised of
 an elongated horizontally disposed stationary primary gasifier chamber, said chamber having a first end with an inlet for receiving said gasifiable materials into its interior and a second end with outlets for a flue gas discharge stream and char remaining after initial gasification of said gasifiable materials, the horizontal position of said elongated stationary chamber defining an upper and a lower side, and   a rotatable screw conveyor extending through said primary gasifier chamber's interior from proximate said first end to proximate said second end for moving said gasifiable materials therethrough, said screw conveyor comprising an axial member having two ends with a plurality of spiral flights forming a continuous helix around said axial member.   
     
     
         3 . The gasifier system of  claim 1 , further comprising a boiler whereby said flue gas discharge stream is used to produce steam, which steam is used for the steam treatment of said char in the secondary gasifier chamber. 
     
     
         4 . The gasifier system of  claim 2 , further comprising a boiler whereby said flue gas discharge stream is used to produce steam, which steam is used for the steam treatment of said char in the secondary gasifier chamber. 
     
     
         5 . The gasifier system of  claim 1 , further comprising a boiler whereby said flue gas discharge stream is used to produce steam, which steam is used to power a compressor producing oxidizing gas for use in the secondary gasifier chamber. 
     
     
         6 . The gasifier system of  claim 2 , further comprising a boiler whereby said flue gas discharge stream is used to produce steam, which steam is used to power a compressor producing oxidizing gas for use in the secondary gasifier chamber. 
     
     
         7 . The gasifier system of  claim 3 , further comprising a boiler whereby said flue gas discharge stream is used to produce steam, which steam is used to power a compressor producing oxidizing gas for use in the secondary gasifier chamber. 
     
     
         8 . The gasifier system of  claim 1 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         9 . The gasifier system of  claim 2 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         10 . The gasifier system of  claim 3 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         11 . The gasifier system of  claim 4 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         12 . The gasifier system of  claim 5 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         13 . The gasifier system of  claim 6 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         14 . The gasifier system of  claim 7 , wherein said char is conveyed from the primary gasifier to the secondary gasifier via a sealed char conveyor. 
     
     
         15 . The gasifier system of  claim 7 , further comprising a steam control system controlling the distribution of steam for treatment purposes and to power said compressor. 
     
     
         16 . The gasifier system of  claim 14 , further comprising a steam control system controlling the distribution of steam for treatment purposes and to power said compressor.
