Definitions
- the invention relates to a flow guide body on a gas turbine combustion chamber for swirling an impinging air flow, consisting of at least one tapered molded shell of essentially conical shape, the base surface projection of which is formed by at least one straight line and any curve connecting the end points of the straight line, wherein the tip of the molded shell essentially faces the air flow hitting the outside.
- a comparable flow guide body is known from EP-A-0 063 729 as a device for inverting and mixing flowing substances.
- Air atomizers known which have two or more coaxial ring channels, through which the air mass flows conveyed by the compressor with different Stream swirl. It became known in this context already a mixture with fuel; there are two air channels separated by a tapered circular ring on which a fuel film is applied. This is from the air masses to the end edge of the Driven circular ring and atomized there. In the vicinity of the atomizing edge has the fuel drop spray trailing character, what a poor homogeneity of the resulting air-fuel mixture results.
- delta wings To improve the mixing processes of gases in or on gas turbine combustion chambers so-called delta wings have also become known. For this purpose, reference is made, for example, to EP 0 623 786 A1 or to US 3,974,646. Delta wings of this type are sharp-edged Bodies that have an impinging flow field in two each a vortex axis divides possessing partial flows in such a way that the vortex axes run convergent. The mixing processes that can be achieved hereby can be convergent Do not fully satisfy vortex formation.
- the object of the invention is therefore to demonstrate measures by means of which mixing processes of gases in gas turbine combustion chambers can be improved.
- non-convergent and preferably divergent vortex axes or vortex braids are to be generated downstream of the flow guide body.
- the so-called flow guide is in all the figures designated with the reference number 1. It is always a Shaped shell 1 of substantially conical shape.
- the projected Base 2 of this molded shell 1, the interior of which is hollow, is made from a straight line 3a as well as any one, the end points of the straight line connecting curve 3b.
- the molded shell 1 is formed by the Shell surface, which connects the curve 3b with the tip 4 of the molded shell 1. However, those running from tip 4 to curve 3b must Rays not necessarily Be straight, but can even curves represent.
- the shape of this molded shell is the respective one Freely selectable requirements accordingly, d. H.
- the circulation of the pegs 8 is from Angle of attack depends on ⁇ . With a sufficiently high swirl the pegs 8 burst open downstream of the molded shell 1, as shown in Fig. 4. It forms a recirculation zone which has an inner interface 9a to the central main flow of fluid. Further the fluid in rotation has one outer interface 9b to the surrounding main flow fluid, which only displaces under the curvature of its streamlines becomes.
- FIG. 5 A preferred application for an inventive Flow guide body shows Fig. 5.
- each other adjacent, but spaced apart, two molded shells 1 arranged by a broken open Housing 10 are surrounded.
- Each of the two molded shells 1 is the angle of attack ⁇ relative to the horizontal, which is equal to the direction of flow of the fluid stream be employed in such a way that levels 5 of these Shells 1, which were defined in Fig. 3, between enclose the angle 2 ⁇ .
- So-called double-shell atomizer which is essentially from two flow guide bodies 1 according to the invention is an air atomizer with a flame holder, where liquid fuel makes sense on the convex Side of the two molded shells 1 is applied.
- gaseous or solid fuels can also be used also on the convex sides or outer sides of the Shells 1 are applied, then the one shown acts Arrangement as a mixer with flame holder. Always there a stabilization of the flame through the connection 4 illustrated recirculation zone within the split vertebrae (see reference number 8) reached.
- the eddy current field of the molded shell 1 or molded shells 1 perpendicular to a second main stream is quick, for example Air admixture can be achieved in gas turbine combustion chambers.
- This second main stream represents the fuel gas and is sucked into the recirculation zone of the vortex braids 8.
- the fuel gas mixes at the interfaces 9a, 9b (see FIG. 4) with the fresh gas.
- a gas turbine can be arranged to the admixing air optimal with the fuel gas inside the combustion chamber 6, 7 show how to mix.
- the molded shell is again with the reference number 1 denotes while the combustion chamber wall Reference number 11 carries.
- the fuel gas flows according to Arrow direction 13.
- This fuel gas stream 13 should be like known admixture air can be added.
- the admixed air flow 6 as the one hitting a molded shell 1 Fluid flow outside of the combustion chamber 12 along the Combustion chamber wall 11 brought up and can Opening 14 in the combustion chamber wall 11 in the combustion chamber 12 occur.
- the molded shell 1 surrounded by a scoop 15, which is part of the incoming Mixing air flow 6 intercepts and in the direction of Breakthrough 14 redirects. This is the domed scoop 15 arranged on the outside of the combustion chamber wall 11 in such a way that the opening 14 is included.
- the cold admixing air 17 forms with the Fuel gas stream 13 again has an outer interface 9b.
- the admixing air 17 is strongly swirled and compared to that Fuel gas 13 has a high density, it comes from centrifugal and buoyancy forces in the area of this interface 9b to a rapid and intensive rearrangement of both Air masses that lead to fine-grained turbulence and rapid mixing to lead.
- the surface of the interface 9b is around many times larger than that at the previous status technology-forming surface between hot gas and admixing air. The hot gas slip through the admixing level thereby greatly reduced.
- FIGS. 8-10 Another application for an inventive Shaped shell 1 or a flow guide body according to the invention is shown in Figs. 8-10.
- the molded shell 1 in the flow path of two fluid flows namely an air flow 6 and a fuel flow 20 arranged and acts as a so-called shell air atomizer for a fuel film layer.
- the molded shell 1 is again from one surrounded in the form of a hood 15 in which the fuel film layer 21 is arranged.
- the fuel film layer 21 has a fuel channel 22 which in one Flat funnel 23 ends.
- FIG. 10 shows the view Z from FIG. 8 of the fuel film layer 21.
- the fuel channel 22 can be seen as well as the flat funnel 23.
- the outer contour makes sense of the film layer 21 as can be seen aerodynamically shaped.
- 11 shows a double-sided load Double-shell atomizer with two molded shells, similar Fig. 5.
- the Fuel on two channels 22 here without flat funnel 23
- the flow guide body 1 according to the invention or the one according to the invention Shaped shell 1 act in the last explained Exemplary embodiments in connection with a Fuel film layer 21 as a shell air atomizer, wherein the fuel through one or more fuel channels 22 can be supplied, the fuel channels 22 and possibly in one or more Flat funnels 23 open and the atomizer or Shaped shell 1 at a short distance from the flat funnel 23 or is arranged from the mouth of the channels 22, and the film layer 21 in the plane of symmetry of the molded shell (s) 1 lies.
- an inventive Flow guide body or a molded shell 1 also as a vortex generator are used, which then in particular one or more arbitrarily shaped molded shells 1 as well as one or more matching scoops 15 consists.
