Abstract (en)
A nozzle or nozzles for spraying cooling water are disposed at the lower end of a slag suction path. A cooling water down-flow passage 15 is provided on the outer periphery of an inner tube 14 which constitutes a slag suction path. A water sump 21 is provided below the cooling water down-flow passage 15, the water sump 21 being located lower than the each nozzle. A lower end opening 24 of the cooling water down-flow passage 15 is disposed lower than the each nozzle 17A, 17B and is submerged in water in the water sump 21. The cooling water down-flow passage, except the lower end opening, is adapted to be closed up. When the cooling water down-flow passage 15 is closed up, water in the passage is stopped by atmospheric pressure acting upon the surface of the water in the water sump, so that it is prevented from flowing down.
