Abstract:
A furnace for performing an endothermic process, comprising tubes containing a catalyst for converting a gaseous feed, wherein tubes are positioned in rows inside the furnace, wherein burners are mounted between the tubes and between the tubes and the furnace walls parallel to the tubes rows, and wherein the burners rows and the tubes rows are ended by end walls and are divided into sections with, on each row of tubes, the distance from a wall end tube to the end wall being T2W, the distance between two adjacent inner tubes in a section being T2T, and the distance between two symmetry end tubes of two adjacent sections being T2S, wherein the tubes in the rows are arranged in such a way that the ratios T2T/T2W and T2T/T2S are greater than 0.5 and smaller than 2 thus limiting the differences in the heat transfer to the outer tubes (wall end tubes and symmetry end tubes) with respect to the inner tubes and reducing the temperature difference between outer tubes and inner tubes.

Claim (Index 13):
A furnace for performing an endothermic process, the furnace comprising:\n tubes containing a catalyst for converting a gaseous feed, wherein the tubes are positioned in rows inside the furnace; burners mounted between the tubes and between the tubes and furnace walls parallel to the rows of tubes, wherein the rows of burners and rows of tubes are ended by end walls and are divided into sections with, on each row of tubes, the distance from a wall end tube to the end wall being T2W, the distance between two adjacent inner tubes in a section being T2T, and the distance between two symmetry end tubes of two adjacent sections being T2S, wherein the tubes are configured in such a way that a ratio of T2T/T2W and a ratio of T2T/T2S are greater than 0.5 and less than 2 thereby limiting the differences in the heat transfer to a plurality of outer tubes with respect to a plurality of inner tubes and reducing the temperature difference between the plurality of outer tubes and the plurality of inner tubes, wherein the plurality of outer tubes are the wall end tubes and the symmetry end tubes, wherein the plurality of inner tubes comprise the tubes that are not outer tubes.
