<p><P>PROBLEM TO BE SOLVED: To provide a device for injecting a solid particle-shaped material into a vessel. <P>SOLUTION: A refining device includes the vessel, and a solid injection lance 27a extending into the vessel via an opening on a vessel shell wall. The lance includes a center core pipe 31 for passing the solid particle-shaped material, and a ring cooling jacket 32 enclosing the center core pipe over a substantial part of the length. The lance has a fitting structure 61 including a tubular part extending to the periphery of the cooling jacket and having an approximately double diameter of the cooling jacket. The tubular part is interfitted into a tubular lance fitting bracket 62 welded on the outer plate of the vessel shell, and extending to the outside from the vessel. The lance is held on the fitting bracket by a clamping bolt 66 between the tubular part and a flange of the tubular bracket. The tubular part has a double wall, and the space between the walls is divided into a stream current wherein cooling water flows from a water inlet to a drain port. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
