Definitions

  • a tube lining for prismatic combustion chambers having funnels in the lower end.
  • the tube lining portions on vertical walls of the funnel are bent under the tube lining portions on inclined walls of the funnel to overlap the tube lining portions with each other.
  • the overlap covers any space between the reversals of the tube lining portions with respect to the plate jacket surrounding the combustion chamber to prevent heat radiation from within the chamber to pass to the plate jacket.
  • This invention relates to a tube lining for prismatic combustion chambers. More particularly, this invention relates to a tube lining for prismatic combustion chambers having funnels in the lower end zones.
  • prismatic combustion chambers with funnels disposed at the lower zones have been lined with tube linings of tube strip groups.
  • These tube strip groups have been connected in parallel relation and have extended to and fro vertically or horizontally so as to extend in vertical planes.
  • the external boundary for such combustion chambers has been formed by a plate jacket disposed directly behind these tubes while bearing directly thereon.
  • this invention provides a combustion chamber having a funnel disposed in a lower zone and a plate jacket with a tube lining formed of tube strip groups wherein the tube strip groups serving to line the combustion chamber walls which converge with the inclined funnel walls are bent at their joints with the inclined funnel walls with the reversals of such tube strip groups disposed behind the tube strip groups lining the inclined walls of the funnel while extending within the plane of the com bustion chamber walls.
  • the spaces between the reversal bends of the individual tubes and the tube strip groups are consequently always covered by the tubes of the adjacent walls.
  • FIG. 1 illustrates a vertical section taken on line II of FIG. 2 through the funnel of a forced circulation boiler
  • FIG. 2 illustrates a plane view of the funnel of FIG. 1.
  • combustion chamber 1 is terminated at the bottom by a cuniform funnel 2 and is provided with a tube lining.
  • a plate jacket is disposed immediately behind the tube lining while being in hearing contact therewith to bound the combustion chamber 1 towards the exterior.
  • the tube strips 6 which continue above the funnel 2 in the combustion chamber walls have lower reversals 5 in the plane of the inclined funnel walls 4.
  • the tube strips 9 serving to line the vertical funnel walls which constrict in accordance with the inclination of the funnel are bent at their joints with the inclined funnel walls 4 and have reversals 8 disposed below the tube strips 6 between the tube strips 6 and plate jacket 3.
  • the tube strips 6 and 9 are dimensioned so that the spaces between the reversal bends of the individual tubes and the tube strips of one wall are covered by the tubes of the tube strips running along the adjacent wall. Thus, any excessive heat radiation from within the combustion chamber 1 is prevented from acting on the plate jacket 3.
  • a tube lining for lining said combustion chamber having a plurality of tube strip groups connected in parallel to extend to and fro horizontally or vertically, said tube strip groups lining said converging walls being bent at the joint of said converging walls with said inclined walls and being formed with reversals disposed behind the tube strip groups lining said inclined walls within the plane of said walls, and a plate jacket disposed directly behind said tube lining in bearing contact therewith to bound said combustion chamber to the exterior thereof.
