PROBLEM TO BE SOLVED: To provide a control device for eliminating a bridge generated inside a gasification furnace.SOLUTION: A gasification furnace 20 having an inner cylinder 23, supplying a solid raw material 5, in the upper part of an outer cylinder 21 comprises: an agitating member 31 which is inserted into the inner cylinder 23 and whose longitudinal direction is a same direction as the vertical direction of the gasification furnace 20; a raising/lowering drive part 35 which raises and lowers the agitating member 31 between a standby position X separated from the solid raw material 5 deposited in the inner cylinder 23 and prescribed positions Y, Z in the solid raw material 5 inside the gasification furnace 20 located lower than the standby position X; a rotational drive part 36 which rotates the agitating member 31 around an agitating member shaft during bridge elimination movement of lowering the agitating member 31; detection means 25, 26, 27 for detecting a bridge of the solid raw material 5 in the gasification furnace 20; and a control device 28 which controls the raising/lowering drive part 35 and the rotational drive part 36 on the basis of signals from the detection means 25, 26, 27. |
