METHOD OF MANUFACTURING CYLINDRICAL MEMBRANE WALL

摘要

Disclosed is a method for manufacturing a cylindrical membrane wall comprising multiple tubes in which a coolant flows. The method comprises the steps of: manufacturing a plurality of sub-bundles by welding a plurality of tubes to each other after disposing the tubes in a longitudinal direction to be neighbored side by side; manufacturing 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 given curvature by pressing the panel-type bundles; and welding the curved bundles to each other using a jig.
