摘要： The invention relates to an apparatus and a method for utilizing hydrocarbon-containing and iron-oxide-containing waste products, in particular rolling scale sludges, and fine coals, in a metallurgical plant, in which the waste product is mixed with the fine coal, and if appropriate with bituminous substances, and is then agglomerated, in particular cold-briquetted, and is then used to build up the fixed bed in a melter gasifier and is converted in the latter in a melting-gasification zone.

摘要： The present invention provides a method of purifying polluted soil and/or burned ash containing heavy metals and/or organic compounds with a higher throughput than a conventional method. In this method, polluted soil and/or burned ash is dried by, for example, a rotary dryer so that the moisture content is 5% by mass or less, preferably 3% by mass or less, and then large lumps having a particle diameter of 10 mm or more are removed by a vibrating screen. Only an undersize portion is formed into a briquette having a volume of about 6 cm3 by a press molding machine. The briquette is charged in a rotary hearth furnace together with the large lumps, and heated in the furnace to remove or detoxify the heavy metals and organic compounds by evaporation with high efficiency.
