This invention provides a carbonizing apparatus for easily carbonizing a material to a desired state of carbonization, which apparatus requires a reduced installation space, and lowers concentration of harmful gases contained in an exhaust gas. The interior of a cylindrical furnace body 82 having a vertical axis is divided by a partition wall 83 into an upper furnace body acting as a combustion section 80 and a lower furnace body acting as a carbonization section 6 . The partition wall 83 defines a through hole for supplying distillation gas to the combustion section 80 . The carbonization section 6 has a vertical structure, with a supply part 33 disposed in an upper portion for supplying a material under treatment 1 , and a carbide take-out part 35 and a first blowoff part 36 of spontaneous combustion air disposed in a lower portion, so that the material under treatment 1 is movable by gravity toward the take-out part 35 . An agitating device 39 includes agitating members 43 revolvable about a vertical axis. A premix combustion section 81 is provided on the combustion part 80 side of the partition wall 83 for mixing a distillation gas having passed through the through-hole with an exhaust gas discharged from a discharge part 34 and burning the mixture. Gas having passed through the premix combustion section 81 is supplied to the combustion section 80.
