Definitions

  • the invention relates to a combustion chamber arrangement for gas turbines with one connected to at least one burner, in a turbine chamber opening annular combustion chamber, one of which Ring combustion chamber bounding ring combustion chamber wall, double-skin built up and an inner shell of the annular combustion chamber wall detachable from an outer shell of the annular combustion chamber wall arranged lining elements assembled and is between the inner shell and the outer Shell of the annular combustion chamber wall from a cooling medium flowable gap is formed.
  • the invention relates also a gas turbine with such a combustion chamber arrangement.
  • the rail-like rods of those known from the prior art Annular combustion chambers have a length of approximately half Meters so that one is in the axial direction of the combustion chamber in the flow direction in front of or behind the end of the rail-like Assembly room of at least half a bar Meter length must be present. Seen in the direction of flow however, the turbine blades are directly behind the combustion chamber arranged in front of the combustion chamber of the burners, so that neither in front nor behind the rail-like bars is sufficient Space to assemble or disassemble the lining elements remains.
  • the assembly and disassembly of the lining elements an expensive disassembly of the gas turbine.
  • the outer housing must be covered or it must be additionally the runner will be removed, which is an additional high workload for the exchange of the lining elements means.
  • the invention is therefore based on the object of developing a combustion chamber arrangement of the type mentioned at the outset such that an exchange of individual lining elements of the inner shell of the annular combustion chamber wall is possible with comparatively little effort.
  • the invention proposes that the lining elements are trapezoidal, each with an outwardly directed fastening structure formed in each of the longitudinal sides for releasably fastening to a corresponding counter structure of an adjacent lining element and / or a supporting structure connected to the outer shell.
  • the lining elements Due to the trapezoidal design of the lining elements, d. H. which at an angle other than 90 ° to the End edges of the lining elements, as well as those formed laterally on each of the long sides, fastening structures facing outwards are sufficient a slight shift around the trapezoidal liner element of the corresponding counter structures to solve and disassemble.
  • the lining element can do the other way round introduced and by means of a slight shift to be attached to the counter structures.
  • assembling or disassembling of the lining element required axial displacement only 0.1 to 0.05 meters, which is a clear one Shortening the space required compared to that from the State of the art known 0.5 meters. So needs for an assembly or disassembly of the lining elements at a Combustion chamber arrangement according to the invention the gas turbine not to be further disassembled. Neither is it necessary to remove the outer casing and the runner refer to.
  • the grooves can be used as a fastening structure on the long sides of the trapezoidal ones Lining elements can be arranged, the springs as a counter structure on an adjacent lining element or the supporting structure connected to the outer shell.
  • the trapezoidal lining element has a spring on its long side, which in a on an adjacent lining element or on one with longitudinal structure connected to the outer shell attacks.
  • a further relief for the assembly or disassembly of the Lining elements result if these do not overlap extend the entire axial length of the annular combustion chamber, but cover only part of this length, being complete Lining of the ring combustion chamber in the axial direction at least two lining elements arranged one behind the other are. With such a measure, the individual Lining elements are kept small and are easier to do handle.
  • the annular combustion chamber is opposite in its axial extent one due to the axial extension of the turbine space or the turbine shaft angled machine axis arranged.
  • Such an angle results in an In the direction of the turbine chamber, the diameter of the Annular combustion chamber, creating an axial division of the inner Shell of the annular combustion chamber wall inevitably leads trapezoidal segments. So can trapezoidal lining elements are used, all with their narrower end edge in the direction of the turbine space, with your wider front edge oriented towards the burner are arranged.
  • the lining elements each have additional fastening structures exhibit.
  • a fastening opening for the passage of a fixing element, such as a bolt there it is preferred that the mounting opening on a narrower Base side of the trapezoidal lining element arranged is.
  • the lining element can be one of the narrower Long groove arranged on the front opposite side be provided. This can also be done with a Screw bolts are attached. These bolts represent the only fixed points of the construction, the first in two Directions, the second in one direction.
  • a gas turbine is proposed with the invention, which a combustion chamber arrangement with or has several of the features described above.
  • the gas turbine has this an axially displaceable burner insert.
  • a axial displacement of the burner insert can be sufficient Space for moving the trapezoidal lining elements be created.
  • the axially displaceable burner insert is simply in the direction axially displaced away from the combustion chamber assembly, the the resulting space between the burner and the combustion chamber arrangement can be used to make the trapezoidal lining elements axially during assembly or disassembly move.
  • Fig. 1 is a section of a section of a Gas turbine shown, which has a combustion chamber arrangement according to the invention 1 contains.
  • the combustion chamber arrangement according to the invention 1 has an annular combustion chamber 2, which of a surrounded by a double-walled ring combustion chamber wall is.
  • the annular combustion chamber wall is composed of one inner shell 3 and an outer shell 4, being between the inner shell 3 and the outer shell 4 a gap 5 is trained.
  • the gap space 5 is during operation the gas turbine flows through a cooling fluid, which the Inner shell 3 of the annular combustion chamber cools convectively.
  • the inner shell 3 of the annular combustion chamber wall is made up of individual Lining elements 6a to 6d constructed. These are over Support structures releasably with the outer shell 4 of the annular combustion chamber wall connected.
  • At least one burner 18 is connected upstream of the annular combustion chamber, the annular combustion chamber opens into a turbine chamber 19. Die axial extension of the turbine chamber 19 or a turbine shaft defines a machine axis M. About this machine axis M the ring combustion chamber is positioned at an angle arranged.
  • the annular combustion chamber 2 is in the present case Embodiment shown double angled formed, whereby a in the circumferential direction of the annular combustion chamber 2 running dividing line 7 in the inner shell results. Along the dividing line 7 meet in the axial Towards the front, d. H. closer towards Brenner 18 and behind, d. H. closer to the turbine room 19 Lining elements 6a, 6c and 6b, 6d together.
  • the lining elements 6a to 6d are trapezoidal, as can be seen better in the following figures.
  • Fig. 2 shows a perspective view of a section seen from a combustion chamber arrangement 1 according to the invention from the direction of the turbine room.
  • the inner shell 3 of the wall of the annular combustion chamber 2 constructed from trapezoidal lining elements 6a, 6b is.
