Apparatus for manufacturing mineral fiber

Abstract

Provided is a coal briquette manufacturing apparatus including a material storage configured to store a plurality of materials for manufacturing coal briquette; a material mixer configured to mix the plurality of materials discharged from the material storage; a coal briquette manufacturer configured to manufacture the coal briquette by press-forming the materials mixed in the material mixer; and a conveyor provided to the material storage, the material mixer or the coal briquette manufacturer, and configured to transport the plurality of materials or the coal briquette, wherein the plurality of materials includes coal ashes, dolomite, and limestone, and a weight of the coal ashes is 70 to 80% of an entire weight of the plurality of materials.

What is claimed is: 
     
         1 . A re-combustion apparatus comprising:
 a re-combustion chamber comprising an inflow opening through which exhaust gas flows in and an exhaust opening through which the in-flowed exhaust gas is discharged;   a heat source provided on one side of the re-combustion chamber, and configured to supply a heat toward an inside of the re-combustion chamber; and   a heat accumulator provided on the inflow opening within the re-combustion chamber, and configured to accumulate the heat from the heat source,   wherein the exhaust gas flowed in through the inflow opening is re-combustible while passing through the heat accumulator.   
     
     
         2 . The re-combustion apparatus of  claim 1 , which is configured to form an air gap on the heat accumulator to enable the exhaust gas to flow in or be discharged, and the air gap is in communication with the inflow opening. 
     
     
         3 . The re-combustion apparatus of  claim 1 , further comprising:
 a preventer configured to remove combustion residues of impurities within the exhaust gas from the exhaust gas.   
     
     
         4 . The re-combustion apparatus of  claim 3 , wherein:
 the preventer comprises a first dam, and   an inner space of the re-combustion chamber is partitioned by the first dam.   
     
     
         5 . The re-combustion apparatus of  claim 4 , wherein:
 the preventer comprises a second dam, and   the second dam is separated from the first dam toward the exhaust opening.   
     
     
         6 . The re-combustion apparatus of  claim 5 , wherein:
 a first via-hole is formed on a top of the first dam,   a second via-hole is formed on a bottom of the second dam, and   the combustion residues are configured to fall down while passing through the first via-hole or the second via-hole.   
     
     
         7 . The re-combustion apparatus of  claim 5 , wherein:
 a hopper is provided between the first dam and the second dam, and   the combustion residues of impurities within the exhaust gas are externally dischargeable through the hopper.
