Definitions

  • the invention relates to a steam generator suspended or set up on a supporting structure according to the natural circulation or forced circulation system, in particular waste heat boilers according to heat engines with evaporator heating surfaces which run essentially horizontally in a housing and a steam drum which is arranged spatially higher on connecting pipes, in particular downpipes.
  • Standing steam generators are also known (AT-B 310.776), in which the steam drum is supported on the downpipes on a common foundation with the combustion chamber. This construction is limited by the kink length of the downpipes and leads to standing downpipe systems (AT-B 378.250) whose downpipes are connected by a spatial truss.
  • the invention has set itself the task of countering the different thermal expansions of the preferably uncooled housing and the cooled pipe system and taking advantage of the physically given effect that the downpipes and overflow pipes between the drum and the evaporator and the connecting line drum to superheater in about the same temperature (Boiling temperature) and thus have the same thermal expansion.
  • the steam drum is supported on the housing by connecting lines, such as downpipes, at about the height of the collecting chambers of the horizontal evaporation heating surface, so that a large part of the differential expansion of the connecting lines of the drum to the collecting chambers is absorbed by a change in the height of the steam drum regardless of the boiler support.
  • An essential application is the combustion chamberless waste heat boiler.
  • the invention is characterized in that the unheated downpipes and / or connecting pipes through which saturated steam flows are supported, and optionally, approximately at the level of the collecting chambers, in particular inlet collecting chambers of the evaporator heating surface, on brackets of the hanging or standing housing of the steam generator formed by a fin tube wall or an insulated sheet metal wall together with the steam drum via guides, in particular pendulum brackets on the housing, are held elastically. Further features of the invention are specified in subclaims 2-5.
  • the invention is shown, for example and schematically, in the attached figure.
  • the invention shows a heat recovery steam generator after a gas turbine 10, in which the turbine exhaust gas is cooled to generate superheated steam.
  • the steam generated is used, for example, in a condensation steam turbine 11 to generate electricity.
  • the waste heat steam generator is designed according to the natural circulation system with a horizontal evaporator heating surface 3 and has a steam drum 6.
  • the steam drum 6 is supported with its down pipe 1 on a bracket 4, which is arranged on the housing 5 of the hanging steam generator, so that the weight of the steam drum 6 is introduced via the hanging device 12 into the steel structure 13 or via the support into the foundation.
  • the downpipes 1 are guided in a sliding guide 7 on the housing 5, and the steam drum 6 is also guided on the housing by a pivoting lever 7 ', so that no differential vibration can occur between the housing and the steam drum in the event of an earthquake.
  • the downpipes 1 are connected at their support via pipe bends 8 to the inlet plenum 2 of the evaporator heating surface 3, wherein the pipe bend 8 can be made very short.
  • the wet steam generated is passed through the risers 9 into the steam drum, separated from entrained water there and is finally fed to the superheater as saturated steam.
  • the evaporator heating surface 3 is preferably formed by finned tubes or finned tubes.
  • the inlet plenums can also be stored on the console 4 to avoid differential expansion.
  • the steam generator can also be arranged standing on a foundation, the downpipes which carry the drum being supported on the wall of the steam generator via brackets in the region of the inlet collecting chamber of the horizontally lying evaporator heating surfaces. It is also advantageous in waste heat steam generators to arrange the superheater surfaces 14 below the evaporator heating surfaces 3, so that the hot exhaust gases first coat the superheater heating surfaces 14 and then the evaporator heating surfaces 3. Connecting tubes through which saturated steam flows can also be used to support the steam drum, which generally allow a larger diameter and thus a longer (larger) overall height.
