Abstract

PURPOSE: To provide an effective recovery of heat of the molten slag by a method wherein the molten slag is casted and solidifed with a casting mold having thermal medium circulated therein, the solidified slag is broken into particles, the remaining holding heat recovered by the gaseous thermal medium is applied to the thermal medium.
CONSTITUTION: Molten slag 2 is fed into the casting mold 7 to receive heat from the slag through the partition wall having a thermal conductive characteristic in the thermal medium (such as water) circulation devices 8aW8f and then transmitted to the thermal medium. After the molten slag is solidifed, it is dropped into the slag hopper 11, broken down to a desired size with a slag crusher 12 and fed to the solid-gas heat exchanger 14. Gaseous thermal medium such as air etc. is fed into the solid-gas heat exchanger 14 with a gaseous thermal medium circulation pump 15 and at the same time the heated thermal medium due to its recovered heat is fed to the heating boiler 19. The thermal medium is fed to the heating boiler 19 through the pipe 21 with the thermal medium circulation pump 20 to perform a preheating, the heat is recovered through the circulation devices 8aW8f and then supplied to the turbine 23.
