<p>In a method for gas treatment of coal wherein coal (1, 2) is loaded on a moving mesh conveyor (111, 112) having a quadrilateral mesh and heated gas (11, 12) is circulated from above and below so as to bring the heated gas (11, 12) into contact with the coal (1, 2) via the mesh of the mesh conveyor (111, 112), two layers of coal for lower level stacking (1A, 2A) having a diameter (Dl) that is greater than twice the length (Lss) of the short side of the mesh of the mesh conveyor (111, 112) are loaded on the mesh of the mesh conveyor (111, 112) and coal for upper level stacking (1B, 2B) having a diameter (Du) that is twice said length (Lss) or less is loaded on the coal for lower level stacking (1A, 2A).</p> |
