ABSTRACT:
The furnace for baking carbonaceous blocks comprises, along the longitudinal X direction of the furnace, a series of sections, each section comprising, in the transverse Y direction, hollow walls (3) through which a heating gas flow comprising combustion gas or a cooling air flow circulates, alternating with pits containing carbonaceous blocks to be baked, each of the said hollow walls (3) in a section being in communication with a wall in an upstream section and/or a wall in a downstream section, so as to form a conduit through which the said gas flow circulates, each of the said walls of a section comprising two vertical lateral partitions (38) in the X-Z plane, and elements in the transverse Y direction for deflecting the said gas flow passing through the said wall and maintaining a constant spacing between the said lateral partitions (38), and characterized in that each wall (3) comprises a means of maintaining, over at least one third of the length L of said wall, a gas flow of rate D uniformly distributed over the entire normal cross-section S, with a decree of uniformity of the distribution of said flow of rete D defined by the expression "2yD-0.5yD/yS", where "2yD-0.5yD" denotes the extent of the range of the flow D corresponding to a fraction y of the said normal cross-section S, and in which y is not more than 0.25.
