1. A cooling wall comprising:
a wall surface defined by arrangement of central axes of a plurality of cooling tubes in which a cooling medium flows; and
an opening formed in a part of the wall surface in which a burner is inserted and installable,
wherein each of the plurality of cooling tubes forming the opening has a straight portion and a curved portion,
wherein the plurality of cooling tubes include
a first cooling tube whose first virtual axis extending in an axial direction of the straight portion overlaps the opening, and
a second cooling tube whose second virtual axis extending in an axial direction of the straight portion is located outside an outer circumference of the opening in a radial direction,
wherein the curved portion of the first cooling tube is arranged so as to form a curve along the outer circumference surface of the opening and on a surface along the wall surface, or arranged so as to be spaced apart by a predetermined distance or less from the wall surface in a direction orthogonal to the wall surface and form a curve,
wherein the curved portion of the second cooling tube is arranged so as to be spaced apart from the first cooling tube in a direction orthogonal to the wall surface and form a curve, and
wherein the curved portion of the first cooling tube is arranged so as to be spaced apart from the wall surface in a direction orthogonal to the wall surface with the predetermined distance being less than or equal to a pitch of the same length as a diameter of the first cooling tube.
