Development of revabratory furnace in Egyptian Copper Works (ECW) by using reformed natural gas

摘要

In ECW, revabratory furnace which used for smelting of scrape of copper and residual anodes and cathodes from the next stages which carried out in copper after casting from this furnace. In this time, deoxidation process carrying out by wood as a resource of reduction gases such carbon monoxide, hydrogen and methane. That is the problem, using of wood causes the following: (1) Pollution of medium of copper melting (forming soot of smock above furnace) (2) low efficiency in removal of oxygen from copper and more contamination in copper matte causes in rising of heat to remove of it and increasing in cost and time of casing of copper (3) high expencincive this problem was solved by using of reformed natural gas as a source of reduction gases (CO+ H_2).
