Abstract

1409971 Melting mineral ROCKWOOL AB 2 Jan 1973 [11 Jan 1972] 193/73 Heading C5G In a method of melting mineral in a cokefired shaft furnace, batch coke lumps, fed into the furnace and passed vertically down through the furnace in countercurrent to hot stack gases, are coated with a solid surface layer of melting point sufficiently high to prevent reduction of the CO 2 in the stack gases by the coke up to the edge of the combustion zone. The surface layer may be applied by spraying a slurry on to the lumps or dipping them in a slurry or paste. The slurry may be of lime in water. Binding agents such as glue or plaster, or soluble or hydraulic binding agents may be present. The surface layer may also contain material soluble in the bloom of the mineral, e.g. metal oxide.
