Definitions
- the invention relates to a gas turbine combustor with combustion chamber shingles, with the combustion chamber shingles on a support structure of the gas turbine combustion chamber are attached and each have at least one mixed air hole, which arranged in alignment with a mixed air hole in the supporting structure is.
- the constructions known from the prior art are formed so that the diameter of the mixed air hole Support structure (shingle support) at most slightly larger is than the diameter of the mixed air hole of the combustion chamber shingle.
- the difference in size is used in the prior art just to make sure that the worst possible combination of all manufacturing and assembly tolerances the edge of the Mixing air hole of the combustion chamber shingle not from the edge of the Mixed air hole of the support structure is towered over.
- the object of the invention is a gas turbine combustion chamber with combustion chamber shingles of the type mentioned To create kind, which with simple construction, simpler, less expensive Manufacturability and easy assembly a high Has lifespan and overheating of the entire construction avoids.
- the diameter of the Mixed air hole of the support structure is significantly larger than that Diameter of the mixed air hole in the combustion chamber shingle.
- the configuration according to the invention is characterized by a A number of significant advantages.
- Diameter of the mixed air hole of the support structure and the Mixing air hole of the combustion chamber shingle can be achieved that due to the strong back pressure on the thickened edge of the Combustion chamber shingle when there is a gap between the Combustion chamber shingle and the supporting structure, which by a Overheating of the clapboard is caused, additional Cooling air from the mixed air hole into the interior of the shingle flows and thus intensifies the cooling of the combustion chamber shingle.
- Adaptive cooling is thus implemented according to the invention, in which the amount of cooling air automatically depends on the temperature load the combustion chamber shingle is adjusted.
- the effusion holes can be on the back the surface of the combustion chamber shingle or in the edge of the shingle begin, being on the inside of the shingle or the Support structure facing side can enter.
- the effusion holes end on the surface of the combustion chamber shingle or on the inside of the mixed air hole in the combustion chamber shingle.
- the effusion holes can be without or with a peripheral component around the axis of the mixed air hole. Hot gas side the combustion chamber shingle.
- the amount of cooling air in the initial state the gas turbine combustion chamber can be selected that it is just sufficient for normal operation.
- the maximum amount of air thus stands for the reduction of harmful gas to disposal.
- the Combustion chamber shingle is subjected to greater thermal stress automatically increases the cooling, so that a long-lasting and safe operation is possible.
- Fig. 1 shows a schematic side sectional view of a gas turbine combustor known from the prior art.
- a cover 1 of a combustion chamber head is shown.
- Reference number 2 denotes a base plate
- Combustion chamber shingles are identified by reference number 3.
- the combustion chamber shingles 3 have mixed air holes 4 and are attached to a support structure 6.
- With the reference symbol 5 is a heat shield with a hole for a burner Designated 8.
- a turbine guide vane is located at the outlet of the combustion chamber 9 is shown schematically.
- the reference number 10 denotes a guide vane in the compressor outlet.
- On Combustion chamber outer casing 11 and a combustion chamber inner casing 12 limits the combustion chamber.
- Fig. 2a and 2b show the design of a mixed air hole 4 of the combustion chamber shingle 3 and a corresponding one Mixed air hole of the support structure 6 according to the prior art. It can be seen that the diameter 13 of the Mixed air hole of the support structure 6 is slightly larger, than the diameter 14 of the mixed air hole 4 of the combustion chamber shingle 3. From Fig. 2b it can be seen that the air flow 15 in the mixed air hole 4, additional air from the interior of the shingle draws.
- Figures 3a and 3b show the configuration according to the invention in an analogous representation to Figs. 2a and 2b. It can be seen that the diameter 13 of the mixed air hole of the Support structure 6 is clearer or significantly larger than that Diameter 14 of the mixed air hole 4 of the combustion chamber shingle 3. From Fig. 3b it can be seen that a dynamic pressure of the Air flow 15 for an additional inflow of cooling air leads into the interior of the shingle as soon as there is a gap forms between the support structure 6 and the shingle edge 7.
- Fig. 4a shows a partial area in an enlarged view a combustion chamber shingle according to the invention 3 it can be seen that by the shingle edge 7 in the area of the mixed air hole 4 additional effusion holes 16 are provided are to cool air from the shingle interior to feed the combustion chamber shingle 3.
- the effusion holes 16 in different orientations be arranged to the level of the combustion chamber shingle 3.
- the Effusion hole 16a is arranged at a very shallow angle, while the effusion holes 16b and 16d extend through the Shingle edge 7 extend and at a larger angle to Main plane of the combustion chamber shingle 3 are aligned.
- the Effusion hole 16e extends almost perpendicular to the main plane the combustion chamber shingle 3 and flows through the edge of the shingle 7th
- Fig. 4b shows two different versions of the effusion holes 16 in the top view of the mixed air hole 4 of the combustion chamber shingle 3.
- the effusion holes are each arranged radially (regardless of the respective angle of inclination according to Fig. 4a), while in the right figure of Fig. 4b an additional Tangential components around the axis of the mixed air hole or a tangential arrangement of the effusion holes 16 is realized is. This enables particularly efficient cooling respectively.
