See full text

A carbonization apparatus for coal with wide particle size distribution, a carbonization apparatus unit, and a carbonization method using the apparatus. The apparatus includes a char discharge outlet, a combustion heating chamber, a coal feeding inlet, a pyrolysis gas exhausting pipe, and two partition plates between which a pyrolysis gas channel is formed. Orifices are provided on the partition plates to form a gas flow path from the fuel bed to the pyrolysis gas channel. The pyrolysis gas channel in the carbonization apparatus permits the gaseous products generated from coal pyrolysis to flow out in a timely manner.
