Zusammenfassung:	The purpose of the present invention is to reduce a portion which is arranged inside a furnace wall and exposed to a high-temperature inside gas and to simplify an opening structure. This cooling wall (111) is provided with: a wall surface (111S) on which shaft centers of a plurality of cooling pipes are formed; and an opening part (11) which is formed on one portion of the wall surface (111S) and in which a burner can be installed. The plurality of cooling pipes (9) that form the opening part (11) each have a straight-line portion and a curved shape portion, the plurality of cooling pipes (9) including: a first cooling pipe (9A) in which a first virtual shaft extending in the axial direction of the straight-line portion is superposed on the opening part (11); and a second cooling pipe (9B) in which a second virtual shaft extending in the axial direction of the straight-line portion is located radially outside the outer periphery of the opening part (11). The curved shape portion of the first cooling pipe (9A) is arranged so as to form a curve in a surface along the wall surface (111S) along the outer peripheral surface of the opening part (11), and the curved shape portion of the second cooling pipe (9B) is arranged so as to be spaced apart from the first cooling pipe (9A) in a direction perpendicular to the wall surface (111S) and form a curve. Le but de la présente invention est de réduire une partie qui est disposée à l'intérieur d'une paroi de four et exposée à un gaz intérieur à haute température et de simplifier une structure d'ouverture. La paroi de refroidissement (111) selon l'invention comporte : une surface de paroi (111S) sur laquelle des centres d'arbre d'une pluralité de tuyaux de refroidissement sont formés; et une partie d'ouverture (11) qui est formée sur une partie de la surface de paroi (111S) et dans laquelle un brûleur peut être installé. La pluralité de tuyaux de refroidissement (9) qui forment la partie d'ouverture (11) ont chacun une partie de ligne droite et une partie de forme incurvée, la pluralité de tuyaux de refroidissement (9) comprenant : un premier tuyau de refroidissement (9A) dans lequel un premier arbre virtuel s'étendant dans la direction axiale de la partie de ligne droite est superposé sur la partie d'ouverture (11); et un second tuyau de refroidissement (9B) dans lequel un second arbre virtuel s'étendant dans la direction axiale de la partie de ligne droite est situé radialement à l'extérieur de la périphérie extern
