PURPOSE: An apparatus for supporting a shroud nozzle is provided to prevent the thermal deformation of the nozzle and to prevent air from flowing inside the nozzle. CONSTITUTION: An apparatus for supporting a shroud nozzle includes a mouth ring (100) and a gas feeding unit. The nozzle is held on the mouth ring having a jetting nozzle part jetting a gas upwards. The gas feeding unit selectively feeds air for cooling and inert gas for forming a gas curtain to the jetting nozzle part. The jetting nozzle part includes multiple jetting holes (111), a main flow path (112), and multiple branch flow paths (113). The jetting hole is opened toward the upper side of the mouth ring. The diameter of the jetting hole becomes wider upwards so that the jetting hole has an inclined surface. The main flow path is connected to the gas feeding unit. The branch flow paths inside the body of the mouth ring are branched off from the main flow path, and are respectively extended from the bottoms of the jetting holes. |
