<p>PROBLEM TO BE SOLVED: To provide a carbonization apparatus which is easy to adjust temperature in accordance with the dry distillation state of each zone (region) in an axial direction of the rotary carbonization furnace and can retain a uniform and desired dry distillation state over the entire region within each region and simultaneously has a simple structure, and a rotary carbonization apparatus capable of quickly, easily and arbitrarily controlling an air amount since it is possible to directly measure the temperature in any zone in the axial direction of the rotary carbonization furnace by inserting an air blowing tube having an air nozzle from the an inlet direction of the rotary carbonization furnace into the innermost and, at the same time, easy to control the dry distillation rate and the temperature and, in addition, capable of surely avoiding generation of harmful substances by burning the generated dry distillation gas under control in a secondary combustion tower, and then cooling. SOLUTION: The rotary carbonization apparatus has a material supply device, a rotary carbonization furnace body arranged in the cross direction, a tower-type secondary combustion chamber arranged at the rear end of the carbonization body, and a plurality of air blowing pipes being arranged inside the furnace of the carbonization body and the plurality of air blowing pipes having air blowing openings capable of blowing a controlled amount of air into the spaces separated from each furnace bottom of a plurality of regions within the above furnace.</p> |
