Definitions
- the present invention provides a hot gas-carrying housing of the type mentioned, which is characterized in that the fastening web is provided along its circumference with a plurality of the fastening web in the axial direction severing slots, each having at least a first slot portion, starting from extends outwardly from the free end of the fastening web.
- Such slots which are produced according to the invention preferably by means of water jet cutting, act as discharge sections and compensate for thermally induced tightening ⁇ voltages in the transition region between the housing inner wall and the fastening web. Investigations have shown that the slot load change number can be improved many times thanks to the arrangement of such slots.
- Housing inner wall and the shaft is a hollow cylindrical shaft protection jacket is arranged, which has an outwardly projecting and provided with a fastening web of the hot gas Ge ⁇ housing receiving circumferential groove annular shoulder on has, by a predetermined amount in the radial direction of the housing inner wall of the hot gas-carrying housing
- FIG. 3 shows a perspective partial view of that in FIG. 2
- Figure 6 is a front view of a fastening web according to a second embodiment of the present invention
- Figure 7 is a front view of a fastening web according to a third embodiment of the present invention
- Figure 8 is a front view of a fastening web according to a fourth embodiment of the present invention.
- the figures show a gas turbine plant 1 according to an embodiment of the present invention or components thereof.
- the gas turbine plant 1 comprises a gas turbine housing 2, which accommodates a compressor 3 and a turbine 4, which are connected to one another via a shaft 5. Further includes the gas turbine plant 1 two in Figure 1 unspecified Darge ⁇ presented combustion chambers, which are arranged as Silobrennhuntn side of the gas turbine housing 2 and connected via a corresponding piping 6 with a recorded in the gas turbine housing 2 hot gas bearing housing 7 fluidly connected.
- the hot gas-carrying housing 7 comprises a hot gas channel 8 with a substantially annular cross-section.
- the hot gas channel 8 is bounded on the inside by a housing inner wall 9 and the outside by a housing outer wall 10, wherein at the
- the fastening strip 14 is held in a circumferential groove 20 which is formed ⁇ at one by a predetermined amount in the radial direction of the housing inner wall 9 spaced arranged Ringab ⁇ set 21 of a hollow cylindrical shaft protective jacket 22 surrounding the shaft 5 in the area of the hot gas-carrying housing 7 and between the shaft 5 and the
- the cooling air channel 27 is continued byde Kunststoffbohrun ⁇ gen 28, which extend axially through the annular shoulder 21 and radially inwardly of the circumferential groove 15 are formed.
- Another annular cooling air channel 29 is defined between the wave protection jacket 22 and the blast protective jacket 24 and fluidly connected via the cooling air openings 23 to the first cooling air channel 27.
- first slot section 35 which extends radially outwards starting from the free end of the fastening web 14
- second slot section 36 connected to the first slot section 35 and crossing it
- two hook-like transition slot sections 37 which extend connect to the free ends of the second slot portion 36 and facing each other
- third slot portions 38 which adjoin the transition slot sections 37 and extend in wesent ⁇ union parallel to the first slot portion 35.
- the slots 39 according to FIG. 8 comprise a first slot section 40 which extends radially outwards starting from the free end of the fastening web 14, a second slot section 41 connected to the first slot section 40 and crossing it and to the free ends of the second slot section 41 subsequent and hook-like curved formed Schlitzendabchae 42, whose free ends are facing each other substantially, wherein the rounding or the radius of the Schlitzendabête 42 is substantially larger than that of the Schlitzendabchae 33 shown in Figure 6 is selected.
- Figures 9 and 10 show an alternative design of the invention From ⁇ the range shown in FIG. 4 Shown is the housing inner wall 9, which is provided adjacent to the hot gas outlet opening with a radially inwardly projecting annular attachment web 43. Its mountings ⁇ supply ridge 43 is provided along its circumference with a plurality of these by separating slots in the axial direction 44, which starting from the free end of the fastening web 43 extending radially outwardly and are arranged at equal intervals with a predetermined pitch. Furthermore, the fastening web 43 is provided with a plurality of elongate passage openings. gene 45, the number of which corresponds to the number of slots 44, wherein the through holes 45, the slots 44 intersect and together with these form a substantially T-shape.
