Definitions

  • the invention relates to a steam generator suspended or erected on a supporting structure, according to the natural circulation or forced circulation system, in particular waste heat boilers according to heat engines, with a steam drum arranged above and essentially horizontally running pipes of the evaporator heating surface which are connected by connecting pipes, e.g. Downpipes and risers are connected to the evaporator heating surface.
  • DE-B 1929 286 discloses variable-length pendulum supports for compensating for expansion between the combustion chamber wall and the surrounding support structure.
  • Standing steam generators are also known (AT-PS 310.776), in which the steam drum is supported by 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-PS 378.250) whose downpipes are connected by a spatial framework.
  • the invention has set itself the task of countering the different thermal expansions and exploiting the physically given effect that the downpipes and overflow pipes between the drum and evaporator and the connecting line between the steam drum and superheater have about the same temperature (boiling temperature) and thus the same thermal expansion, and to support the steam drum on the housing approximately at the height of the collecting chambers of the evaporator heating surface, preferably via downpipes, 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 height of the steam drum independently of the boiler support.
  • the invention is characterized in that the connecting pipes, in particular downpipes, approximately at the level of the collecting chambers, in particular the inlet collecting chamber, of the evaporator heating surface are supported on brackets of the housing of the hanging or standing steam generator and the steam drum is supported. Further features of the invention are specified in subclaims 2-8.
  • 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 or the forced circulation system with a horizontal evaporator heating surface 3.
  • 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 to prevent a relative vibration between the downpipe and the housing wall.
  • the steam drum 6 is guided by a pivot lever 7 'on the housing, so that no differential oscillation between the housing 5 and the steam drum 6 can occur even in the event of an earthquake.
  • the housing 5 is usually formed by an insulated sheet metal wall, but can also be designed as a fin tube wall.
  • 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 finally fed as saturated steam to the superheater heating surfaces 14, which are surrounded by the hot exhaust gases in front of the evaporator heating surfaces 3 and are arranged below the evaporator heating surfaces 3 for this purpose.
  • the evaporator heating surface 3 is preferably formed by finned tubes or finned tubes.
  • the inlet plenum chambers can also be stored on the console 4 in order to avoid differential expansion.
  • the steam generator can also be arranged standing on a foundation, the downpipes carrying the drum being supported on the wall of the steam generator via brackets in the region of the inlet collecting chamber of the evaporator heating surfaces lying horizontally.
  • connecting pipes through which saturated steam flows can also be used, which generally have a larger diameter and a greater kink length and thus allow a longer (larger) height of the steam generator.
