- Gas turbines such as those offered by the applicant under, for example, the type designation GT13E2 are operated with an annular combustion chamber.
- the combustion itself is preferably, but not exclusively, via premix burners (hereinafter referred to as burners for short), as they emerge, for example, from EP-A1-321 809 or EP-A1-704 657, these publications and the publications derived therefrom
- the gas turbine 10 illustrated in FIG. 1 has a turbine housing 11, which encloses a plenum 14 filled with compressed combustion air in the region of the combustion chamber 15. Concentrically around the central rotor 12 around the plenum 14, the annular combustion chamber 15 is arranged, which merges into a hot gas duct 22. The space is bounded inwardly by an inner shell 21 'and outwardly by an outer shell 21. Inner shell 21 'and outer shell 21 are each in one
- Dividing plane divided into upper part and a lower part.
- Upper part and lower part of inner and outer shell 21 ', 21 are connected in the parting plane so that an annular space is formed, which directs the hot gas generated by the burners 16 on the blades 13 of the turbine.
- the parting line is required for assembly and disassembly of the machine.
- the combustion chamber 15 itself is lined with special wall segments 17.
- Inner and outer shell 21 ', 21 are convectively cooled in the embodiment described.
- cooling air which enters the plenum 14 coming from the compressor as a compressor air flow 23, flows primarily in the opposite direction of flow of the hot gas in the hot gas duct 22 From the plenum 14 from this cooling air then flows through an outer and inner cooling channel 20 and 20 ', which cooling channels through the shells 21, 21 'are formed at a distance surrounding cooling shirts 19, 19'.
- the cooling air flows in the cooling channels 20, 20 'along the shells 21, 21' in the direction of the combustion chamber hood surrounding the combustion chamber 15. There, the air is then available to the burners 16 as combustion air.
- the hot gas flows to the turbine (blades 13) and thereby along the hot gas side surfaces of the inner and outer shell 21 ', 21.
- the flow along these surfaces is not homogeneous, but is influenced by the arrangement of the burner 16th
- Inner and outer shell 21 ', 21 are loaded both thermally and mechanically. These loads, also in connection with the mode of operation, determine the service life of the inner and outer shell 21 ', 21 and the resulting inspection intervals.
- the above-mentioned non-uniformities of the flow occur both on the hot gas side and on the cooling air side.
- the hot gas side nonuniformities result primarily from the burner assembly.
- the cooling air side irregularities are primarily caused by internals in the cooling channels 20, 20 '. Presentation of the invention
- the object is solved by the entirety of the features of claim 1. It is essential for the invention that this uniformity is achieved by an intervention in the cooling, in order to compensate for local irregularities in the thermal load of the shell or in the flow of the cooling medium in the cooling channeldehemd respectively corresponding local deviations in the leadership of the cooling medium flow having. As a result, the cooling can be locally enhanced in a simple manner in order to reduce corresponding local thermal overloads.
- An embodiment of the invention is characterized in that on the outside of the shell in the cooling channel protruding internals are present, and that caused by the internals local constriction of the cooling channel is compensated by a corresponding local Kontuherung thedehemds.
- the local contouring of the cooling skirt may include a dome extending in the cooling jacket over the region of the internals and projecting outwards.
- Another embodiment of the invention provides that to compensate for a occurring at a certain place, increased thermal stress on the shell or to compensate for a caused by internals local constriction of the cooling channel at this location means for introducing additional cooling air in the Cooling channel are provided, wherein, when the cooling jacket is acted upon on the outside of under elevated pressure cooling medium, the means for introducing additional cooling air into the cooling channel preferably comprise cooling openings in the cooling jacket.
- the thermal engine in question may be a gas turbine having a combustion chamber and the hot gas passage from the combustion chamber leading to a first series of blades.
- the combustion chamber may be annular and separable in a parting plane, wherein the hot gas channel is delimited by an outer shell and an inner shell, and by an appropriate inner and outerdehemd an inner and outer cooling channel is formed.
- the gas turbine comprises a compressor for compressing sucked combustion air, wherein the output of the compressor communicates with a plenum, and the combustion chamber is arranged with the adjoining hot gas channel and the adjacent cooling channels in plenum and surrounded by the plenum that compressed air from the Plenum against the hot gas flow in the hot gas channel through the cooling channels flows to the combustion chamber arranged burners.
- the burners may advantageously be designed as premix burners, in particular as double-cone burners.
- FIG. 1 shows the longitudinal section through a cooled annular combustion chamber of a gas turbine according to the prior art.
- FIG. 2 shows in several subfigures 2A to 2D a cooling channel without internal obstacles with a local (dome-like) adaptation ineredhemd (Figure 2A) according to an embodiment of the invention, and without adaptation (Figure 2B), as well as one with ribs equipped cooling channel with a local (Dom-like) adaptation ineredhemd according to another embodiment of the invention ( Figure 2C), and without adaptation (Figure 2D).
- FIG. 3 shows in several subfigures 3A to 3D a cooling channel with internal internals with a local (dome-like) adaptation ineredhemd according to another embodiment of the invention, as seen in the flow direction (Fig. 3A) and transverse to the flow direction (Fig. 3B ), as well as the arrangement according to FIG. 3A, B with additional cooling air supply according to another exemplary embodiment of the invention, seen in the flow direction (FIG. 3C) and transversely to the flow direction (FIG. 3D);
- FIG. 4 shows a perspective side view of a cooling shirt divisible in a parting plane for a gas turbine annular combustion chamber with local adaptations according to another exemplary embodiment of the invention
- FIG. 5 shows an enlarged detail of the cooling jacket from FIG. 4 with a ring segment having the local adaptations
- the cooling channel cross section is defined by the existing contour of the inner or outer shell and a modified, i. adapted in shape of cooling air sheets (cooling shirts), which are mounted on the inner and outer shell.
- a cooling channel formed between the shell 21 and the cooling jacket 19 is shown in cross-section transverse to the flow direction of the cooling air 24 and the hot gas flowing in the opposite direction 25, which has a constant in the illustrated section flow cross-section.
- a local change of the flow cross section can now be brought about by providing the cooling jacket (locally) with a bulge in the form of a dome 26. Due to the dome 26, which can extend over a greater length in the flow direction (perpendicular to the plane of the drawing) (see FIGS. 3B and 3D), there results a local enlargement of the cooling channel cross section, which leads to a locally improved cooling and thus to the reduction of one can contribute to this increased thermal stress occurring.
- Such a step is particularly suitable when ribs 27, which project inwards in the cooling channel 20, are present on the outside of the shell 21 as obstacles.
- Such a local dome 26 lends itself to the local improvement of the cooling in particular if - as shown in FIGS. 3A and 3B - special, the cooling flow obstructing internals 28 in the cooling channel 20 are present.
- the dome 26 is then conveniently adapted in width and length to the disabling internals 28.
- cooling air 29 can be guided through corresponding openings in the cooling jacket 19 to the critical location. For this purpose, it is necessary that on the outside of thedehemdes cooling air under higher pressure, in particular from the surrounding plenum 14, is available.
- FIGS. 4 to 6 show, in a perspective side view, a cooling jacket 19 (divisible in a parting plane 31, outer) for a gas turbine annular combustion chamber with local adaptations according to another exemplary embodiment of the invention.
- the cooling jacket 19 is composed of a plurality of similar segments 30.
- a selected segment 32 is provided, which has local modifications to optimize the cooling.
- this selected segment 32 which adjoins the dividing plane 31 and comprises a corresponding connection strip 33, is equipped on the one hand with an elongated dome 26.
- cooling openings 35 and 34 are arranged in the segment sheet through which - analogous to Fig. 3C and 3D - additional cooling air can enter from outside into the cooling channel.
