Abstract (en)
[origin: EP0370144A1] A coal-moisture control process, characterized in that a mono species or a mixture of several species of coal containing the volatile matter of 45 wt% or less on the dry ash free basis, including the portion of the particles size of 3 mm or less by 75 wt% or more, and containing the water content of 20 wt% or less on the wet ash free basis is introduced into a plurality of tubes (1) are disposed in and along the axial direction of an inclined rotational cylinder (10) of a coal-in-tube type tube dryer, and a heating medium such as steam is passed along the outer surface of the tubes (1) for the purpose of indirectly heating the coal so as to dry it so that the water content on the wet ash free basis is made 4 to 7 wt%, has enabled efficient and economical moisture control of the coal having relatively high coal rank such as coaking coal.
