ABSTRACT:
An improved method and apparatus for making coke wherein the coal is heated by the walls of a multi-cell chamber means and wherein said walls are heated by electric induction in the absence of air; the raw gases from the coal are directed to a by-product plant. The coal is introduced into said chamber means and the coke is discharged from said chamber means in such a way as to provide positive displacement of both the coal and the coke to overcome the sticking and bridging properties of the coal and the coke within said chamber means. Also improved provisions are included for insuring the sealing of said chamber means while operating said chamber means under a positive pressure in order to increase the efficiency of the conversion of coal to coke without causing pollution. The coal, after being coked, is quenched to a temperature below its ignition point before being exposed to the atmosphere to prevent it from burning in order not to cause pollution nor lose yield.
