Claims5
A suspended steam boiler including a steam boiler upper portion (1), having a vertical tube wall (2) composed of vertical tubes (3) with vertical webs (4) formed there between and a steam boiler lower portion (5) suspended from the vertical tube wall including an inclined tube wall (6) composed of inclined tubes (7) and inclined webs (8) formed there between, the inclined tubes having upper terminal regions (9), terminating in horizontally mutually staggered relationship at the upper edge of the inclined tube wall and a coupling strip (10) being formed along the upper edge of the inclined tube wall, having a plurality of vertical tube bends (11) including connecting limbs (12) projecting from the coupling strip and vertical limbs (13) formed into the coupling strip, and being welded to the vertical tubes (3), and having a plurality of inclined tube bends (14) having connecting limbs (12) projecting from the coupling strip and inclined limbs (15) formed into the coupling strip, welded to the terminal regions (9) of the inclined tubes, the coupling strip (10) being welded to the inclined tube wall (6) below the inclined limbs of the inclined tube bends along the inclined limbs (15) and above the terminal regions of the inclined tubes along the terminal regions (9) and the suspension of the steam boiler lower portion (5) from the vertical tube wall (2) is brought about by welding of the coupling strip (10) to the inclined tube wall and by the welding of the vertical limbs (13) of the vertical tube bends of the coupling strip to the vertical tubes (3) of the vertical tube wall, without the steam boiler lower portion being supported on or from additional external tensile or support elements.
