This invention discloses a new method for the production of coke from coals. In the present invention, coke is continuously produced by heating a moving charge of coal inside the annular space between two tubes. The coking chamber, which includes a large tube and a smaller tube, is force-fed with a coal such as a metallurgical coal. The coal is bi-directionally heated along a controlled temperature gradient between the outer wall of the small tube and the inner wall of the large tube. The coal is transformed to coke as it travels through the annulus of the coking chamber. Coke is discharged from the chamber at the end opposite to which it was charged and is cooled before being exposed to the atmosphere. Gases generated during the coking process are collected and treated. All of these operations are accomplished in a closed system to prevent pollution. |
