PURPOSE: A method and an apparatus depriving heat from high-temperature slag are provided to efficiently deprive heat from high-temperature slag by forming high temperature gradient between the high-temperature slag and a tubular reactor. CONSTITUTION: An apparatus depriving heat from high-temperature slag comprises a molten slag atomizer, a slag particle retaining vessel(4), and a catalyst reactor(7). The molten slag atomizer atomizes molten slag discharged from a transfer container. The slag particle retaining vessel retains the atomized slag with free fall. The catalyst reactor is installed within the slag particle retaining vessel and deprives heat from the slag particles.
