Abstract
Disclosed is a method for producing a cylindrical membrane wall including a plurality of tubes having a coolant passing through an inner part thereof. The method includes producing a plurality of sub-bundles by welding a plurality of tubes to each other after longitudinally arranging the tubes to be adjacent to each other in parallel, producing a plurality of panel-type bundles by welding the sub-bundles to each other, forming a plurality of curved bundles having a curved surface of a predetermined curvature by pressing the panel-type bundles, and welding the curved bundles to each other using a jig.
