Method and installation for utilizing hydrocarbon-containing and iron-oxide-containing waste materials, in particular rolling scale sludges, and fine coals

Abstract

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.

1 . Apparatus for using waste products containing hydrocarbon and iron oxide, the apparatus comprising: 
 a metallurgical plant, comprising an agglomerating installation for producing agglomerates from a mixture of hydrocarbon containing and iron oxide containing waste material with a fine coal; and comprises    a melter gasifier for receiving and utilizing the agglomerates.    
   
   
       2 . The apparatus of  claim 1 , wherein the waste material is a rolling scale sludge.  
   
   
       3 . The apparatus of  claim 2 , wherein a bituminous material is mixed with the waste material.  
   
   
       4 . The apparatus of  claim 1 , further comprising a homogenization apparatus upstream in a path of the waste material toward the agglomeration installation for receiving and homogenizing the waste material and the fine coal for delivering them mixed to the agglomeration installation.  
   
   
       5 . The apparatus according to  claim 4 , further comprising a metering device for introducing the waste material and the fine coal into the homogenization apparatus.  
   
   
       6 . The apparatus of  claim 5 , wherein the metering device is operative for metering addition of at least one of fine coal and waste material and other charge materials.  
   
   
       7 . The apparatus of  claim 6 , wherein the other charge materials include at least one of metallurgical dusts and a binder.  
   
   
       8 . The apparatus of  claim 5 , further comprising a vessel for storage of at least one of fine coal and waste material and other charge materials.  
   
   
       9 . The apparatus of  claim 8 , further comprising a vessel for storage of at least one of fine coal and waste material and other charge materials.
