    摘要: 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 cross-section (13) defined by two concentric tubes (11, 12). The coking chamber (13), which includes a large diameter tube (11) and a concentric smaller diameter tube (12), is force fed with a coal such as metallurgical coal. The coal is bi-directionally heated along a controlled temperature gradient between the inner wall of the small diameter tube (12) and the outer wall of the large diameter tube (11). The coal is transformed to coke as it travels longitudinally along the axis of both tubes. 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.
