A METHOD FOR CONNECTING TWO ROWS OF SECTIONS IN A RING FURNACE AND A DEVICE IN CONNECTION WITH SUCH A METHOD

摘要

The present invention concerns a method and a device for connecting firing gas passages in an outermost section in one row in a ring furnace for calcining of carbon bodies to firing gas passages in the matching outermost section in the parallel row via a connecting duct (1). The active flow cross-section in the connecting duct (1) is gradually reduced in the direction of flow of the firing gas by installing a flow director (2) inside the connecting duct (1). This results in the firing gases being distributed as evenly as possible between the firing gas passages (6, 6') in the head wall (7) and problems associated with uneven gas distribution in the first sections in the furnace rows being minimised.
