Abstract (en)

[origin: ES271050U] In order to preserve the quality of treated coking coal, the drying and preheating operation is performed in consecutive stages. For this purpose, a set of superimposed containers is provided with vertically oriented pipes for a heating medium, the pipes in each container having separate inlets and outlets. The bottom region of each container is further provided with horizontally directed pipes having separate inlet and outlet for receiving a pressure medium which is discharged into the bottom region of each container to produce a whirling bed of the coal. In this manner, the coal is preliminarily dried in the uppermost container, then additionally dried and preheated in the intermediate container, and heated to the desired final temperature in the lowermost container.
