Definitions

  • the present invention relates to a method of installation of a steam generator.
  • the height h n is equal to the total height H of the boiler, that is to say that during the assembly of the ceiling. on the ground, the entire supporting structure is erected, the ceiling is then disassembled into two parts, the central part of which is gradually raised to full height, the parts of the boiler being suspended from this part successively in a position a few meters from the ground .
  • the assembly of the entire structure carrier takes a significant delay, before which it is impossible to lift the ceiling and suspend games of boiler.
  • the invention provides a faster mounting method.
  • said height h n is less than the total height H of the support structure and steps for lifting the ceiling and mounting the boiler parts are performed step by step simultaneously with stages of erection of the supporting structure up to its total height H.
  • the ceiling can be temporarily placed at heights h i on temporary laying beams supported by horizontal master beams of the supporting structure.
  • the ceiling can be temporarily placed at heights h i on mounting pads supported by the pylons of the support structure.
  • the lifting of the ceiling can be carried out by hydraulic jacks fixed on temporary support beams supported by horizontal master beams of the support structure or on temporary extensions supported at heights h i by horizontal beams of the support structure.
  • Figures 1 to 5 show in perspective the different stages of mounting a boiler depending on the process according to the invention.
  • Figure 6 is a partial perspective view of a variant.
  • a steam generator is created of a supporting structure 1 in the form of a tall tower total H, of a ceiling 2 fixed at the top of this structure and parts of the boiler 3 suspended from this ceiling 2 and total height h.
  • the supporting structure 1 consists of pylons 1A connected by horizontal beams 1B and 1C braces. Such a boiler, once assembled, is shown in Figure 6.
  • the supporting structure 1 is erected at its total height H, simultaneously with the previous step, as shown in Figures 3 and 4 and then raise the ceiling 2 to the height H, thanks to the jacks 5 installed at the top of the supporting structure 1, as shown in FIGS. 4 and 5. Possibly parts of the boiler 3 may still be mounted a few meters from the ground, during this last ceiling lifting operation 2.
  • the jacks 5 are attached to gantry-shaped risers 8 for allow the lifting of the ceiling 2 to the level of last horizontal beams 1B.
  • this type of installation of the jacks 5 can also be used for intermediate installations of jacks 5, in place of the temporary support beams 6.
  • This variant makes it possible to arrange the jacks 5 at the height h i for installing the ceiling 2.
  • the ceiling 2 is supported by horizontal beams 1B which must be masters and dimensioned accordingly.
  • the installation and fixing of the ceiling 2 can be carried out on the pylons 1A of the supporting structure 1. This can be obtained for example by installing on the pylons 1A, at heights h i , lateral mounting pads 9 connecting with the ceiling 2.
  • This variant, shown in FIG. 6, makes it possible to lighten the horizontal beams 1B of the supporting structure 1 and therefore requires a less powerful crane 7.
  • the height h 1 is substantially equal to the height h of the boiler parts 3.
  • Steps (a) and (b) described can be broken down into several successive stages of lifting the ceiling 2 and suspension of boiler parts 3.
