CONTROL PROCESS FOR AN ANODE BAKING FURNACE AND ADAPTED FURNACE USING SUCH PROCESS

摘要

THE INVENTION RELATES TO A METHOD FOR ADJUSTING AN OVEN FOR BAKING CARBON ANODES, INCLUDING: LONGITUDINAL HOLLOW WALLS IN EACH OF WHICH A BAKING HOT GAS STREAM CAN FLOW, THE HOLLOW WALLS DEFINING CELLS THEREBETWEEN FOR RECEIVING THE ANODES TO BE BAKED, AND A HEATING SYSTEM ROTATING RELATIVE TO THE HOLLOW WALLS AND INCLUDING AN UPSTREAM MANIFOLD FOR BLOWING AIR INTO THE VARIOUS WALLS, A DOWNSTREAM MANIFOLD FOR DRAWING THE GAS FROM THE VARIOUS WALLS, AND AT LEAST ONE HEATING MANIFOLD. THE METHOD INCLUDES A PHASE OF NATURAL PREHEATING THE WALLS AND THE ANODES WHICH RELEASE VOLATILE COMBUSTIBLE MATERIALS THAT BURN IN THE HOLLOW CELLS AS A DEGASSING FRONT IN A NATURAL PREHEATING AREA OF THE OVEN DOWNSTREAM FROM THE HEATING MANIFOLD. ACCORDING TO THE INVENTION, THE METHOD COMPRISES MODIFYING THE GAS STREAM FLOWING IN THE HOLLOW WALLS SO AS TO CONTROL THE GAS STREAMS (30, 31) PASSING THROUGH A FIRST NATURAL PREHEATING AREA USING THE GAS STREAMS (31) EXITING A SECOND NATURAL PREHEATING AREA (Z2) IN ORDER TO CONTROL THE POSITIONING OF THE DEGASSING FRONT.
