Method and device for charging coke ovens with compacted coal by use of a charging plate separator layer

Abstract

Disclosed is a method and device for charging the chambers of a coke oven with compacted coal. The method includes placing a plurality of adhesion reduction particles onto a coke oven charging plate, the particles being configured to reduce at least one of adhesion forces and friction forces present between the charging plate and compacted coal to be loaded thereon, loading compacted coal onto the charging plate, moving the charging plate loaded with compacted coal to the coke oven chamber, and slidably removing the compacted coal from the charging plate such that the compacted coal is disposed in the coke oven chamber. The device comprises a metal plate configured to load compacted coal into the coke oven, a plurality of adhesion reduction particles affixed to the metal plate by an adhesive layer, and a device used to move the metal plate to a front of the firing chamber of the coke oven.

         10 . A method for charging the chambers of a coke oven with compacted coal, comprising:
 placing a plurality of adhesion reduction particles onto a coke oven charging plate configured to charge the coke oven with compacted coal, the adhesion reduction particles being configured to form a separating layer between the charging plate and the compacted coal to be disposed thereon so as to reduce at least one of adhesion forces and friction forces present between the charging plate and compacted coal, so as to reduce the force required to slidably remove the compacted coal from the charging plate;   loading compacted coal onto the charging plate, the compacted coal having the form of at least one of (1) a plurality of stacked compressed blocks of coal or (2) a compressed coal cake;   moving the charging plate loaded with compacted coal to the coke oven chamber; and   slidably removing the compacted coal from the charging plate such that the compacted coal is disposed in the coke oven chamber.   
     
     
         11 . The method of  claim 10 , further comprising:
 compression molding coal directly on the charging plate to form compacted coal;   
     
     
         12 . The method of  claim 10 , wherein said slidably removing the compacted coal from the charging plate is accomplished by at least one of pushing the compacted coal off of the charging plate and into the coke oven chamber, or pulling the charging plate laterally out from under the compacted coal disposed within the coke oven chamber. 
     
     
         13 . The method of  claim 10 , wherein the plurality of adhesion reduction particles are sand. 
     
     
         14 . The method of  claim 10 , wherein the plurality of adhesion reduction particles are fine coke. 
     
     
         15 . The method of  claim 10 , wherein the plurality of adhesion reduction particles are ash. 
     
     
         16 . The method of  claim 10 , wherein the plurality of adhesion reduction particles include at least one of sand, fine coke, and ash. 
     
     
         17 . The method of  claim 10 , wherein the plurality of adhesion reduction particles are scattered across an upper surface of the charging plate. 
     
     
         18 . The method of  claim 10 , wherein the plurality of adhesion reduction particles are affixed to the charging plate by means of an adhesive layer. 
     
     
         19 . A charging plate for loading a firing chamber of a coke oven with compacted coal, comprising:
 a metal plate configured to load compacted coal into the firing chamber of the coke oven;   a plurality of adhesion reduction particles affixed to said metal plate by an adhesive layer, said particles being configured to reduce adhesion forces between said metal plate and compacted coal to be disposed thereon; and   a device used to move the metal plate along a front of the firing chamber of the coke oven.   
     
     
         20 . The charging plate of  claim 19 , wherein said plurality of adhesion reduction particles are fine coke, and the adhesive layer is tar.
