PROBLEM TO BE SOLVED: To provide a gasfication furnace integrated with a dust collector which has a lower equipment cost, hardly causes tar troubles and shorten the start-up time of the equipment. SOLUTION: A small-sized cyclone 5 is connected with an introducing pipe 5a extendingly disposed in a radius direction, and a discharge pipe 5b for char and ash penetrating through an insulating fire material wall is extendingly disposed from the lower center part of the cyclone 5 to the outside of the gasfication furnace 1, on the upper end of the side peripheral wall of a free board part 2d. A gas-exhausting cylinder 5c is extendingly disposed upward from the upper center part of the cyclone 5. A plurality of cylindrical filters 8 are radially arranged with intervals in the radius direction of the upper part of a furnace main body 2. The upper surface 3a of the insulating fire material wall 3 is inclined downward from one end to the other end in a space part 4a in an outside-furnace casing 4 and a discharge pipe 6 for char and ash is arranged penetrating the outside-furnace casing 4 at the lowest position of the upper surface 3a of the insulating fire material wall 3. A gas-exhausting cylinder 7 is extendingly disposed upward through the top surface of the outside-furnace casing 4. COPYRIGHT: (C)2006,JPO&NCIPI
