FIELD: metallurgy, in particular, methods of cooling of incandescent fluid blast-furnace slag. SUBSTANCE: for recuperation of considerable part of heat of incandescent fluid blast blast-furnace slag, this slag together with fuel (coal) is introduced in reactor where with the help of supplied water steam and use of heat of fluid slag, loaded fuel is gasified to obtain fuel gas containing, in particular, CO and H2 which is withdrawn from cooled material to use for different purposes. EFFECT: higher efficiency. 19 cl, 2 dwg
