Fluidized bed carbonization

摘要: A continuous process is described whereby particulate woody materials are carbonized in a fluidized bed to form solid and gaseous fuel. The includes injecting materials, on basis, into of previously material. Off-gas from carbonization with entrained charcoal fines continuously removed above the bed, coarse surface bed. If desired, high ash, fraction may also be immediately grid. off-gas fine separated cyclone system, collected for use as separator scrubbed, if or utilized directly an enriched Alternate embodiments apparatus this invention include oval-shaped toroidal plurality feeders disposed at preselected positions extending maximize efficiency
