Definitions

  • the invention relates to a flow guide body for separate management of a cooling fluid flow and one Cooling fluid outflow for closed cooled combustion chambers from Turbines.
  • Closed cooled combustion chambers of turbines can be used in its wall, for example, a hollow tile construction exhibit.
  • Such known constructions have a central attachment, a circular feeder and a circular drain for a cooling fluid.
  • the circular feed and the circular discharge for the Cooling fluid are made rotationally symmetrical trained flow guide body separately.
  • This known construction due to the intersecting and discharges a very complex construction of the Outer shell of the combustion chamber.
  • the flow guide body has a cross section with non-rotationally symmetrical cross-sectional shape in a flow guide portion.
  • a flow guide body with non-rotationally symmetrical Cross section can be the cross section like this be formed in four segments, for example Forms flow paths that run side by side through the Kick the outer shell.
  • the cross section is designed so that one around this the circumference defined by the contour of the cross section in at least two separate parts are divided. The inflow or outflow can then take place in these separate parts for a cooling fluid to take place.
  • the flow guide body can be an 8-shaped one Have cross-section. There are separate flow paths each inside the two loops of the 8th educated. Other flow channels can be combined with a circular element surrounding the 8 between the Waists of 8 and the circular element formed become. A total of four can be separated from each other Realize flow paths. For example, two of the a total of four flow paths for the supply of cooling fluid be used, for example the two inside the Loops of 8 flow paths, two more can be used to guide cooling fluid that escapes be, for example, that between the surrounding circular wall and the two waist areas of the 8th trained areas. However, others are, too symmetrical cross-sectional shapes such as one Double eight, a ring with a star inside or something similar possible.
  • the Flow guide body in the flow guide section Through openings for the passage of flowing cooling fluid on.
  • the fluid flow can be in one direction, for example the inflow, through the flow guide body, the other stream, for example the outflow at which Flow guide body are passed. this leads to a very good separation of the two flow paths.
  • the invention further specifies a Flow guidance structure for cooling fluid guidance in one closed cooled combustion chamber of a turbine, the one contains flow guide body according to the invention.
  • a flow control structure can be in one a turbine's cooled combustion chamber closed the top achieve the advantages described.
  • the flow guide structure can be one fluidically with a through the flow guide body directed cooling fluid supply associated with a variety shower insert with fine openings have the cooling fluid entering for impingement cooling a flapper steers.
  • the Flow guide structure according to the invention for impingement cooling be used.
  • the shower insert becomes a corresponding geometric shape and have a distribution of the passage openings.
  • the flow guide structure of the shower insert according to the invention be plate-shaped, the Flow guide body on its the shower insert facing side has a bent edge on which the plate-shaped shower insert rests, and the shower insert with the flow guide body connected is. That way, by Through openings in the flow guide body conducted cooling fluid over an enclosed space, the through the bent edge of the flow guide body is defined for the shower insert and through it get on the baffle. back Transferred Flow guide fluid flows around the edge of the Flow guide body and comes back to that Flow guide cross-section, there to the for the management of the Downstream areas provided.
  • connection between the Flow guide body and the shower insert can have a arranged in the central region of the flow guide body Take place in which to attach the shower insert a through this Screw bolt can be screwed in.
  • the recording points preferably a circumferential collar on which in assembled state of the bolts the shower insert suppressed. This way, it is easy and detachable Attaching the shower insert securely and essentially sealingly attached to the flow guide body.
  • the flow guide body and the this connected shower insert in a connector in a receiving space formed in the connector is used, the flow guide body structures, for example, knob-like elevations, which for Transmission of a power flow at the connector attack.
  • the connector is used to connect the Flow guide structure on a combustion chamber wall, in one Area in which in the combustion chamber wall Through openings for the supply and discharge of cooling fluid are provided.
  • the baffle plate an edge of the connector surrounding the receiving space put on and welded to it.
  • Flow guidance structure of the flow guidance body with a 8-shaped cross section in a circular opening of the Connector used the circular opening surrounds the 8-shaped cross-section in the manner of a perimeter, and the circular opening is together with the 8-shaped one Cross section of the flow guide body in a circular Recess in a combustion chamber wall inserted sealingly, wherein the flow guide body the circular recess divided into four segments, two to one Cooling fluid supply and two to a cooling fluid discharge are connected.
  • FIG. 1 is an exploded view of an inventive Flow guide structure 1 shown.
  • the Flow guide structure consists of one Baffle plate 2, one with through openings 4 Shower insert 3, a flow guide body 6 and one Connector 10.Shower insert 3, flow guide body 6 and connector 10 are by means of a bolt 5th held together.
  • the connector 10 has a circular connection opening 22 for connection to a Combustion chamber wall, the connection opening 22 a encircling collar 23.
  • To connect to the A seal 11 is used in the combustion chamber wall.
  • the Flow guide body 6 has a in the central area Recording with a circumferential collar 19 (see Fig. 2), through which the bolt 5 is passed Flow guide structure presses the bolt 5 to shower insert 3 firmly against the surrounding collar.
  • the plate-shaped shower insert 3 is then with its edge on a bent edge 21 of the Flow guide body 6.
  • the baffle plate 2 in turn lies on a one formed in the connector 10 Recording space limiting edge 24 of the connector 10 on and is welded to it.
  • the baffle plate 2 in Area above the bolt on an access opening 25, the can be closed with a stopper 20.
  • the flow guide body 6 has one Flow guide cross section 7, the one rotationally symmetrical shape deviates.
  • the Flow guide cross section 7 is 8-shaped and forms together with the circular connection opening in the Connector 10 a total of four flow guide areas out.
  • Inlets 9 are in the two loops of FIG. 8 trained in the areas between the waist of FIGS the circular connection opening of the connector 10 are Outlets 8 formed.
  • the center of the 8-shaped Flow guide cross-section is from the connecting bolt 5 penetrated. In the area of the loops of FIG Flow guide body 6 through openings through which therethrough cooling fluid into a between the bent edge 21st and the shower insert 3 formed thereon Flow guide space arrives.
  • FIG. 2 is a perspective, cut open Representation of the flow structure 1 according to the invention in a Combustion chamber wall 12 is shown integrated. With arrows the flow path of a cooling fluid through the Flow guidance structure indicated.
  • Through feeders 13 passes cooling fluid through the inlets 9 of the Flow guide body 6 to the shower insert 3 and over the openings 4 on the baffle plate 2. From there that Cooling fluid in the between the baffle plate 2 and the shower insert 3 formed gap around the front of the Flow guide body 6 directed around to the outlets 8. From there, the cooling fluid passes through an outlet 14 again through the combustion chamber wall 12 and will dissipated.
  • Burner openings 16 through which through which the ignited gas enters the combustion chamber 15.
  • discharge channels 17 are applied in that through the flow guide structures coolant flowing through passes through the outlets 14 and discharged in the axial direction along the combustion chamber becomes.
