Definitions
- the invention relates to a closed-cooled combustion chamber for a turbine.
- Such combustion chambers are of an inner wall and surround an outer wall having a double wall, wherein one with one between the inner wall and the outer wall Cooling fluid, usually cooling air, more flowable Space is left.
- a cooling fluid usually cooling air
- the outer wall is often double-shelled Hollow tile formed, the hollow tile by urgent, in the space between the outer wall and the Cooling fluid supply pipes opening into the inner wall Hollow tile are formed. The one through the feed pipes interrupted cavity formed in the hollow tile is used to discharge the heated cooling fluid.
- a closed-cooled combustor for a turbine with a combustion chamber defining inner wall and an outer wall, wherein a through-flow with a cooling fluid space is left between the inner wall and the outer wall, with an opening into the space the cooling fluid supply and a cooling fluid discharge for discharging the cooling fluid from the intermediate space, wherein the cooling fluid discharge has channel-like discharge structures running essentially along the axial alignment of the combustion chamber, which are interrupted by inlet structures of the cooling fluid supply arranged between the discharge structures.
- the combustion chamber is the outer wall as a double-shell Hollow tile formed and the discharge structures inside the hollow tile are intermediate walls in the axial direction lined up in the combustion chamber, the hollow tile outstanding guide tubes for the supply of cooling fluid formed, the guide tubes at least in the Outer shell of the hollow tile one in the axial direction Combustion chamber have elongated opening cross-section.
- the guide tubes in the axial direction the rows arranged at least in the combustion chamber Outer shell of the hollow tile with its narrow sides have a smaller distance from one another than the distance from Openings in adjacent rows.
- This configuration will a further improved channeling of the outflow Cooling fluids in the channels formed between the rows achieved.
- the guide tubes in the outer shell of the Hollow tile an opening cross-section with an elongated shape and a circular one in the inner shell of the hollow tile Have opening cross-section.
- the advantage of the channel-like discharge structure achieved for the cooling fluid on the other hand, that for the Supply of cooling fluid favorable circular shape in the Maintain gap opening opening of the guide tube.
- the guide tube is along its axial extent shaped so that it is avoiding an elevated Flow resistance from the elongated "slot shape" the opening in the outer shell of the hollow tile to the circular opening in the inner shell of the hollow tile superimposed.
- the outer shell of the Hollow tile a detachably fastened, preferably screwed, sealing plate, which has an opening closes, through which a detachably fastened, preferably screwed, section of the inner shell is accessible.
- a detachably fastened, preferably screwed, section of the inner shell is accessible.
- This construction can be a simple one for example for maintenance and repair purposes required access to the one surrounding the combustion chamber Inner wall can be created. Is also on in this wall the location of the access openings in the hollow tile closable opening attached, is also the inside of the Combustion chamber accessible.
- the solution of the sealing plate brings furthermore the advantage that the provision of an opening in the double-shell hollow tile without increased structural Effort can be made.
- This construction is characterized by a small number of components that go beyond that can be designed in exactly the same way as the one surrounding the opening Rest of the hollow tile.
- the derivation structures by the outer wall, formed in the axial direction of the Combustion chamber-extending discharge channels are formed between which are each arranged the inlet structures.
- the outer wall of the Combustion chamber instead of a double-walled hollow tile generally single-walled wall used on the outside individual, extending in the axial direction of the combustion chamber Discharge channels are attached.
- the making of one, is basically single-shell outer wall, since it is these parts are usually cast parts, clearly easier than in the case of the hollow tile.
- this second embodiment provided that circular formed in the outer wall Discharge openings open into the discharge channels. To derive the the gap between the outer wall and the inner wall leaving cooling fluids are distributed over the outer wall circular discharge openings arranged.
- the circular shape of the Discharge openings is of fluidic reasons from Advantage. Several circular discharge openings open into one the discharge channels in which the derived cooling fluid is collected and directed away.
- the discharge channels on the Outer wall by on the outside of the outer wall trained, extending in the axial direction of the combustion chamber Ribs covers are formed.
- a two-part design of the discharge channels still allows further simplified manufacturing process of the outer wall. This can be made as a simple, single-shell cast part become.
- the ribs need to be formed the formation of cavities in the form of Discharge channels are not required. These are only later formed by putting on the covers.
- the ribs can be on their base structures for blending circular Have openings on a linear channel.
- the Outer wall 1 shows a first embodiment of an outer wall 1 a combustion chamber according to the invention in a detail, three-dimensional representation.
- the Outer wall 1 is designed as a double-shell hollow tile. It has an outer shell 2 and one in the direction of Combustion chamber facing inner shell 3.
- Guide tubes 4 connect the outer shell 2 and the inner shell 3 together for supplying a cooling fluid.
- the guide tubes 4 point in the outer shell 2 elongated oval openings 5 and in the Inner shell 3 circular openings 6.
- the Guide tubes 4 in the axial direction of the combustion chamber lined up in a row that the narrow end faces of the elongated oval openings 5 almost meet and that between the oval openings 5 of guide tubes 4th adjacent rows a greater distance than between the Openings 5 remain in the rows.
- Cooling fluid exits a space (not shown) between the outer wall 1 and a (not shown) Inner wall of the double-walled combustion chamber through openings 7 into the cavity 9. There it gets into the channel-like Diverter structures 8 and is targeted in the axial direction of the Brenner inside the hollow tile Outer wall 1 removed.
- FIG. 1 shown outer wall.
- a so-called manhole is in the outer shell 2 formed as a hollow tile outer wall 1 a circumferential Recess formed through which bolts 14 are accessible.
- the bolts 14 With the bolts 14 is a removable segment 15 on the rest of the as a hollow tile trained outer wall 1 fixed.
- the recess 10 through a screwed sealing plate 11 closed.
- the sealing plate 11 has openings 13 on, passed through the bolts 12 and with the Outer shell 2 are screwed.
- the removable segment 15 is structurally the same as the rest of the Outer shell 1.
- the outer wall 1 shown here is not designed as a hollow tile, but consists of one single-shell wall 20, which in the axial direction of the Combustion chamber extending ribs 21.
- covers 22 are placed to form discharge channels and welded to the ribs.
- the so educated Discharge channels open into discharge openings 23 through which derived cooling fluid emerges.
- openings 7 for draining cooling fluid.
- the area between the ribs 21, not of covers 22 to form Discharge channels are covered, contains circular openings 6 for supplying cooling fluid.
- the ribs 21 are at their base for transferring the circular openings 6 are wave-shaped. To this In this way, cooling fluid entering between the discharge channels can in a wide area, not shower-like in the shown space between the outer wall 1 and one Penetrate inner wall.
- This embodiment shown also enables an in radial dimension of the combustion chamber reduced dimensioning the outer wall, it also offers the advantage of a easy manufacture of the outer wall, as this single-shell cast part with ribs is made and on the Ribs the covers are welded on.
