<p>The present invention is equipped with: a pool (1) in which water is stored; a cylindrical container (2) which is erected in the pool and an upper-end opening of which is covered, while a lower-end aperture (3) is submerged in the open state in the water; a molten slag (S1) inflow port (12) provided in the ceiling wall (8) of the cylindrical container; a slag heat recovery chamber (2A), which is defined within the cylindrical container and the upper part of which forms a steam chamber (4) that accumulates steam while the lower part forms a water seal chamber (5) that holds water, thereby preventing the escape of the steam in the steam chamber, and which brings the water into contact with the molten slag flowing in from the inflow port, thereby producing solidified slag through cooling and causing the solidified slag to settle in the water in the water seal chamber, and generating steam; a steam extraction port (7) that extracts the steam in the steam chamber to the outside; a slag transfer conveyor (30) that receives and transfers the slag that has settled in the water in the water seal chamber; and a spray nozzle (6) that sprays water (W) onto the molten slag flowing in from the inflow port, thereby water-granulating the slag.</p> |
