Abstract

A char making apparatus comprises a longitudinal pyrolyzer furnace housing wherein coal-bearing material may be heated to a temperature to fluidize volatile materials therein and plasticize coal in the coal-bearing material. At least two rotatable drive screws are laterally positioned and interleaved within the longitudinal furnace housing and capable of conveying coal-bearing materials through the pyrolyzer furnace housing, each drive screw having a hollow drive shaft and a diverter positioned within the drive shaft to provide heating to the coal-bearing material. A heating jacket about the longitudinal furnace housing provides additional heating to the coal-bearing material. Multiple combustion chambers adjacent the heating jacket and hollow drive shaft burn fluidized volatile materials and exhaust combustion fluids through the jacket and shaft.
