Abstract

The coupling strips are made to accept welding of vertical limbs of vertical tube extending from vertical tube wall (2) to inclined tube wall (6). The coupling strip is formed along the upper edge of the inclined tube wall. The coupling strips supports the suspension of steam boiler lower portion (5) to the steam boiler upper portion (1). The steam boiler lower portion is suspended from the vertical tube wall by welding the vertical limbs of the coupling strip to the vertical tubes of the vertical tube wall, without needing additional external tensile or support elements.
