Abstract (en)

[origin: WO0044942A1] The invention relates to a method for granulating and fragmenting liquid slags, whereby the slag jet is expelled into a cooling reactor and is cooled in the cooling reactor by adding hydrocarbons. The slag jet is expelled into the cooling reactor with hot combustion gases, especially the gases resulting from a complete combustion, wherein conversion to CO and H2 is effected. Burners (4) are disposed above the slag bath in the device for implementing the method, which device comprises a slag tundish (1) and a slag outlet (5), to which a cooling reactor (6) is connected. The slag tundish (1) can be closed pressure-proof. Lines (14) for the hydrocarbons are connected to the cooling reactor. Alternatively, the hot combustion gases of a combustion engine are blown to the liquid slags using a lance (7).
