METHOD FOR REGENERATING INSIDE OF DRY DISTILLATION GAS CHANNEL

PROBLEM TO BE SOLVED: To provide a method for regenerating the inside of a dry distillation gas channel by which the tar and soot adhered and deposited inside the dry distillation gas channel of a carbonization apparatus are treated to maintain the inside of the dry distillation gas channel clean all the time. SOLUTION: The method comprises a step of supplying an air flow from air supply nozzles 15 and 15' which are provided inside the dry distillation gas channel 14 after the completion of a dry distillation step in the carbonization apparatus 10 to burn the tar and soot adhered and deposited inside the dry distillation gas channel 14. The air flow may be supplied from the dry distillation gas channel 14 at a combustion burner 12 side, or a steam flow may be supplied into the dry distillation gas channel 14 at a dry distillation box 13 side.
