PROBLEM TO BE SOLVED: To provide a carbonizing device capable of producing a stable carbonized product by preventing the ashing of a material to be carbonized. SOLUTION: This carbonizing device is constituted of a carbonizing furnace 1, a driving device of a screw conveyer 31, air supply valves 32a-32d, air discharging valves 33a-33c, a pellet forming device 34, a pyroligneous acid producing device 35, a cooling device 36, a waste gas treating device 37 and a high temp. gas generating device 38. The high temp. generating device 38 generates the high temp. gas containing a large volume of steam and having a prescribed temp. in a low oxygen state by spraying a cooling water in a heating furnace while completely combusting kerosine in the heating furnace. The material to be carbonized in a carbonizing furnace 1 is carbonized and dry distilled by supplying the high temp. gas in the carbonizing furnace 1. |
