Abstract
The combustion chamber wall consists of tubes which are inclined to the horizontal and which are welded to one another in a gas-tight relationship via webs. Pairs of vertical tension strips bear against the outside of the combustion chamber wall. Each pair is connected to the wall tubes via a plurality of sheet-metal strips distributed over the height of the combustion chamber wall. The sheet-metal strips are disposed perpendicularly to the combustion chamber wall plane and are cut out in the form of a comb at the edge connected to the wall tubes.
Claims7
A combustion chamber wall comprising
- a plurality of wall tubes each having a horizontal vector;
- a plurality of webs interconnecting said wall in gas-tight relation;
- a plurality of vertical tubes;
- vertical webs connecting said vertical tubes together in gas-tight relation to define at least one wall of a gas flue extending upwardly from said wall tubes;
- pairs of vertically disposed tension strips in contact with said wall tubes and having fork-like prongs extending upwardly and laterally alongside said vertical tubes in secured relation thereto;
- and
- a plurality of comb-shaped sheet-metal strips, at least two of said sheet-metal strips being vertically disposed between and secured to a respective pair of said tension strips in vertically spaced apart relation, each said sheet-metal strip being secured to a plurality of said webs in perpendicular relation thereto.
A combustion chamber wall comprising
- a plurality of wall tubes each having an axis with a horizontal vector;
- a plurality of webs interconnecting said wall tubes in gas-tight relation;
- a gas tight wall of a gas flue extending upwardly from said wall tubes;
- pairs of vertically disposed tension strips in contact with said wall tubes for supporting said wall tubes from said gas tight wall and to effect a heat transfer between said strips and said tubes;
- and
- a plurality of comb-shaped sheet-metal strips, at least two of said sheet-metal strips being vertically disposed between and secured to a respective pair of said tension strips in vertically spaced apart relation, each said sheet-metal strip being secured to a plurality of said webs in perpendicular relation thereto whereby said tension strips are held in contact with said wall tubes to follow variations of temperature in said wall tubes while reducing transient tensile stresses in said wall tubes.
In a steam generator having a combustion chamber wall comprising a plurality of inclined wall tubes;
- a plurality of vertical webs interconnecting said wall tubes in gas-tight relation;
- and a gas tight wall of vertical tubes extending upwardly from said wall tubes for supporting said wall tubes therefrom;
- the combination comprising
- pairs of vertically disposed tension strips alongside and in contact with said wall tubes to effect a heat transfer therebetween;
- and
- a plurality of comb-shaped sheet-metal strips, at least two of said strips being vertically disposed between each respective pair of said strips in vertically spaced relation, each said sheet-metal strip being secured to a respective pair of tension strips and to a plurality of said webs in perpendicular relation thereto whereby said tension strips are held in contact with said wall tubes to follow variations of temperature in said wall tubes while reducing transient tensile stresses in said wall tubes.
