Patent ID: 7509928

Claim:
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.
