Abstract:
1. A char making apparatus comprising: a. a longitudinal pyrolyzer furnace housing wherein coal-bearing material containing volatile materials may be heated to a temperature to fluidize volatile materials therein and plasticize coal in the coal-bearing material; b. at least two rotatable drive screws laterally positioned and interleaved within the longitudinal furnace housing and capable of conveying coal-bearing materials containing volatile material through the pyrolyzer furnace housing, each drive screw having a hollow drive shaft and a diverter longitudinally positioned within the drive shaft, the diverter forming with an inner surface of each drive shaft an inner passageway to provide heat flux from the combustion fluid moving through the shaft to adjacent coal-bearing materials moving through the pyrolyzer furnace housing to enable fluidizing the volatile material therein and plasticizing coal in the coal bearing material; c. a heating jacket about the longitudinal furnace housing along at least a portion thereof in fluid communication with combustion fluid from multiple combustion chambers to provide heat flux from the combustion fluid moving through the heating jacket to heat adjacent coal-bearing materials moving through the pyrolyzer furnace housing to fluidize the volatile material in the coal bearing material and plasticize the coal in the coal bearing material; d. multiple combustion chambers adjacent the inner passageways and adjacent the heating jacket capable of burning fluidized combustion material and exhausting combustion fluids through the inner passageways and through the heating jacket to fluidize volatile material in the coal-bearing material and plasticize coal in the coal-bearing material; and e. a conduit capable of collecting and transferring fluidized volatile material exhausted from the pyrolyzer furnace housing to the combustion chambers to be burned.
