Abstract
PURPOSE: To make current density between graphite plate uniform and to prevent useless heat loss in a direct resistance furnace, by providing one or more pairs of graphite plates facing each other in parallel with the axis of the direct resistance furnace, followed by packing the space between the graphite plates and the wall of the furnace with a granular refractory material.
CONSTITUTION: In a direct resistance furnace wherein a passage for powder coke 4 exists in its central part and the plural graphite electrodes 2 and 2' facing each other are inserted from the side wall 1, the graphite plate 3 and 3' are furnished in parallel with the axis of the furnace a little apart from the side and part in the furnace of the graphite electrodes 2 and 2'. The space formed by the graphite plates 3 and 3', the electrode 2 and 2', and the furnace wall 1 is packed with the granular refractory material. Especially in a fixed layer, the temperature decrease of powder coke near the graphite plate can be prevented, the temperature distribution in a direction perpendicular to the graphite plate between the graphite plates is made almost constant, and the quality of product can be kept uniform.
