BRIDGE ELIMINATION DEVICE FOR GASIFICATION FURNACE

摘要

A gasification furnace has, on an upper portion of an outer cylinder, an inner cylinder for supplying a solid raw material. A bridge elimination apparatus for the gasification furnace includes: a stirring member that is inserted into the inner cylinder and that has a longitudinal direction in a vertical direction of the gasification furnace; and a drive portion that raises and lowers the stirring member between a standby position where the stirring member is separated apart from the solid raw material that accumulates in the inner cylinder, and a predetermined position located in the solid raw material in the gasification furnace under the standby position. The drive portion includes a rotational drive portion that rotates the stirring member about a shaft of the stirring member when an operation to eliminate a bridge is performed by lowering the stirring member.
