The utility model relates to a stove for carrying out heat absorption method, the stove contains the pipe of the catalyst of gaseous state feed that is used for changeing, and wherein each tub in bankis positioned in the stove, wherein the combustor is installed between the pipe with manage and be on a parallel with between the oven of the bank of tubes to wherein the combustor row and the bank of tubes finish with the end wall, to be managed from the wall end in every bank of tubes and divide the stepping section the distance of end wall is T2W, and the distance between two adjacent inner tubes in district's section is T2T to distance between two symmetry end pipes of two adjacent region sections is T2S, and wherein, the pipe in each row is arranged by this way: ratio T2TT2W and T2TT2S are greater than 0.5 and just are less than 2 to the restriction is to the heat transfer of outer tube (wall end pipe and symmetry end pipe) the difference for the inner tube, and reduce the temperature difference between outer tube and the inner tube.
