Abstract

PURPOSE: To provide the title equipment by which steam of high utility is recovered by connecting an airtight tank internally installed with a rotatable molten slag receiver to an aritight granulator through molten slag connecting pipes having a high press. water jet orifice, and setting a steam generator using the resulting high press. steam as a heat source.
CONSTITUTION: Molten slag 2 is allowed to flow into receiver 4 set in tank 3 through manhole 6 at the top of tank 3 to fill the tank. After closing manhole 6 and valve V-3, and opening equalizing valve V-2 and on-off valve V-1 of supply pipes 9, 9' connecting tank 3 to granulator 10, receiver 4 is slowly rotated to supply the slag to granulator 10 at a constant flow rate together with high press. water 8 introduced from the outside of tank 3. High press. steam generated in granulator 10 is fed to separator 15 to remove granulated slag and droplets carried, and the steam is supplied to steam generator 16 to convert a heat source formed by generator 16 into high press. steam 19. On the other hand, granulated slag formed in granulator 10 is stirred with stirrer 11 using water jet, taken out by slurry pump 16, and fed to dehydration vessel 31.
