Definitions

  • the invention relates to a method for construction of steam generators, as used in particular for thermal purposes Use of fossil fuels. About that In addition, the invention relates to an easy to install trained steam generator.
  • Boiler wall designed as a tube wall.
  • the boiler wall is on the outside provided with bandages and stems, to which on Trusses arranged collectors belong.
  • To the boiler wall is followed by a boiler funnel at its lower end.
  • the entire boiler, to which the elements mentioned belong, is suspended in a boiler frame. That on has a corresponding foundation standing boiler frame several with cross bars and scaffold diagonals braced boiler supports on a boiler frame ceiling wear.
  • the boiler scaffold ceiling supports the boiler.
  • the steam generator is at least partially on his Installation site, which is because of the size of the system and the extent of the work involved a relatively long construction period Takes up.
  • the boiler frame is included To erect the boiler scaffold roof, after which the bandages and in the upper part of the boiler the boiler walls from below brought to their installation location and installed there. Usually the internals (secondary heating surfaces) also from below to their installation location between the boiler walls in the upper area of the boiler spent and installed there. The further boiler wall assembly then takes place from top to bottom, with parallel mounting and assemblies on different levels largely are impossible. The assembly of the upper boiler walls, the Installations and the lower boiler walls are therefore seen in time, serial. This determines the assembly time.
  • EP 0777080 B1 addresses this problem corresponding assembly method for steam generators known, in which about the same time as the assembly of the outer Boiler frame and part of the boiler is started. If the boiler frame has reached a certain minimum height, lifting devices are inserted into the boiler frame, one of the boiler scaffolding ceilings lying on the floor (scaffold base) first raise to a first height. In At this height, the boiler components are installed hanging under the boiler frame ceiling. With further construction progress of the outer boiler frame are the lifting devices shifted upwards and the boiler scaffold roof is also further raised to the heat exchanger surfaces to be able to assemble further. After completion of the boiler frame is thus the same time mounted on the Boiler frame ceiling hanging boiler part lifted up and the boiler frame ceiling is attached to the boiler frame.
  • a preferred mode of operation is based on the Boiler frame initially only an outer part of the boiler frame ceiling built. This outer part leaves in the middle an access opening that is preferably smaller than a horizontal section through the boiler. Through this access opening can to the upper part of the boiler wall associated elements such as bandages, stems and pipe registers delivered to the respective installation location by crane become. The lower part of the boiler frame and the boiler sole are not required for this and are kept free.
  • the boiler surrounding walls are thus, for example erected that pre-assembled by means of a crane or individual bandages and stems in the boiler frame lifted and temporarily there on the boiler scaffold ceiling hung up or provisionally on appropriate clipboards be filed.
  • the bandages can be used at the same time with the construction of the upper part of the boiler frame being constructed.
  • stems and pipe registers will be mounted in the upper boiler frame an inner ceiling section of the Boiler frame ceiling built up and / or kept ready.
  • a lifting device for example a strand lifting system erected, the traction means (strands) with corresponding Suspensions of the inner ceiling section are connected.
  • the internals are with support tubes anchored under the boiler scaffold ceiling.
  • the upper part of the boiler is thus built up Unit consisting of a boiler frame ceiling, boiler ceiling and internals.
  • the inner Section of the boiler frame ceiling then step by step are raised so far that from top to bottom the next unit can be installed.
  • To This assembly is then only partial assembly can still be raised using the strand lifting system until the Internals reach their installation position and the interior Ceiling section at the ceiling height of the boiler frame ceiling is raised.
  • the two construction site areas for the upper boiler wall and for the internals are thus vertically one above the other, separated and spaced apart.
  • the boiler scaffold ceiling is in an outer ceiling section and divided an inner ceiling section.
  • the outer The ceiling section of the boiler scaffold ceiling supports the boiler walls with their bandages and stems as well as the inner ones Ceiling section of the boiler frame ceiling. This in turn bears the fittings of the Boiler.
  • the outer ceiling section is the boiler frame and assigned to the boiler walls.
  • the inner section of the ceiling is assigned to the internals.
  • This assembly process is both for once-through steam generators as well as for circulation steam generators. It is also suitable for both vertically piped Boiler walls as well as for steam generators with angled pipes or for steam generators with vertical and inclined pipes Boiler walls.
  • the inner ceiling section is used for pre-assembly of the internals the boiler scaffold ceiling preferably gradually raised to the different from top to bottom one after the other Internals and accordingly their support tubes to be able to assemble. It can be done gradually several economizer coils on top of each other, Reheater coils and superheater coils be erected.
  • the spatial separation of the Construction sites of the upper boiler walls and internals not just a time saver, but also one significant improvement in assembly logistics. Through the Feeding the parts of the upper boiler wall from above remains the scaffold base for the installation of the internals free.
  • the steam generator according to the invention has a split Boiler frame ceiling.
  • Your inner ceiling section has such a dimension that it with internals attached to it through the interior delimited by the boiler walls can be moved.
  • the outer dimensions of the inner The ceiling sections of the boiler scaffold ceiling are therefore smaller than the cross-section of that bounded by the boiler walls Space.
  • internals such as economizers, Reheater and superheater.
  • this preferably mounting connections on the inside of Boiler walls are bounded room.
  • the assembly takes place preferably by welding to pipe bushings or Connecting pipes.
  • the inner section of the boiler scaffold roof also forms the fittings installed on it and possibly a boiler ceiling a pre-assembled assembly. This can then be in the Whole in their place of installation between the already assembled Pipe walls are spent and connected there.
  • This Construction creates considerable assembly advantages because it enables simultaneous assembly or pre-assembly of the Boiler enclosing walls and internals at each other separate places.
  • Ceiling section connected to the outer ceiling section.
  • the connection can be via screw connections or also using non-detachable fasteners such as rivets and welded connections respectively.
  • the boiler scaffold roof can, if necessary, and lifting devices may be provided temporarily. This then form a lifting system around the inner ceiling section the boiler scaffold roof step by step during pre-assembly lift until all internals on the inner ceiling section the boiler scaffold ceiling are suspended. After that you can the lifting system can be used for this, the pre-assembled To lift and hold the assembly to its place of installation, until other holding means hold the assembly in place and for example the inner ceiling section with the outer Ceiling section is connected.
  • the lifting system can be used if necessary be removed.
  • the lifting system can be used by both pulling at the top and pushing from below. Moreover can interact with several lifting systems.
