PROBLEM TO BE SOLVED: To provide partial-combustion-type carbonization equipment for woody waste which uses woody waste such as building waste, separated bulky refuse and thinned wood as a raw material and stably yields a high-quality carbide which does not contain foreign matters by burning a part of the raw material while carbonizing the rest. SOLUTION: The woody waste has disadvantages of poor flow property and foreign matter contamination. A rotary kiln 20 that can be applied to materials with poor flow property is installed in the upstream part, and a fluidized bed furnace 30 which easily removes foreign matter is installed in the downstream part. The woody waste is carbonized in two steps, i.e. in the upstream rotary kiln 20 and in the downstream fluidized bed furnace 30. COPYRIGHT: (C)2004,JPO&NCIPI
