Definitions

  • the invention relates to a combustion chamber arrangement for a gas turbine with a variety of in one, in one Individual combustion chambers leading to the annular space leading to the turbine space, with burners upstream of the individual combustion chambers are that with the individual combustion chambers through an outer casing are connected through.
  • the invention further relates to a Gas turbine with such a combustion chamber arrangement.
  • Such combustion chamber arrangements for gas turbines are in the state of the art.
  • a mixture ignited in the burners from an oxygen-containing fuel gas and a fuel is burned in the combustion chambers and the expanding ones Hot gases are released through the transition sections of the individual combustion chambers in the direction of the turbine chamber and the ones inside Arrangement of guide vanes and rotor blades deflected.
  • The are in the usually circular cylindrical built entrance sections of the individual combustion chambers generated hot gas flows with a circular cross section the transition sections into a hot gas stream with a circular segment Cross section transferred and finally to merged into a circular hot gas stream. This enters the turbine space through the annular gap and drives the blades of the gas turbine.
  • Cooling fluid flows open on the individual combustion chambers over and creates a cooling effect.
  • the cooling fluid flow is not directed and defined, which results in an overall lower cooling efficiency.
  • such a design of the individual combustion chambers structurally simpler and requires less effort.
  • the invention has for its object to further develop a combustion chamber arrangement of the type mentioned in such a way that the cooling efficiency can be increased considerably in the case of individual combustion chambers of simple design.
  • At least one connecting piece which is arranged on a side of the turbine outer casing facing the turbine space and extends radially in the direction of the turbine space and at least partially surrounds a section of at least one individual combustion chamber while leaving a gap space.
  • the arranged on the turbine outer casing according to the invention radially extending in the direction of the turbine space at least a nozzle surrounds one inside the turbine outer casing located section of at least one single combustion chamber and leaves between the wall of the single combustion chamber and the Trim a gap.
  • a cooling fluid can enter this gap flow in and due to the defined flow channel cause more effective convective cooling in this area.
  • the single combustion chamber itself remains unchanged simple in structure, a complication of the construction the single combustion chamber itself is not required. On in this way the quasi closed cooling area of the Single combustion chamber in the interior of the turbine outer casing extended towards the turbine chamber, the cooling efficiency is noticeably improved.
  • the nozzle can of the invention in the circumferential direction of the individual combustion chamber be closed so that it extends over the entire Circumferential area of the single combustion chamber in the section in which the nozzle according to the invention in the interior of the outer housing the gas turbine protrudes, is cooled virtually closed.
  • the invention settles the single combustion chamber from a substantially cylindrical shaped input section downstream of the burner and a transition section fading into a circular ring sector together, the nozzle at least the input section partially surrounds.
  • the entrance section is due its proximity to the burner is particularly thermally stressed Element of the single combustion chamber, so that the possibility of a quasi closed cooling, which is due to the invention provided neck in this area is a significant Improve the cooling of the individual combustion chamber with represents comparatively less expenditure on cooling fluid.
  • a low expenditure of cooling fluid increases the economy of the gas turbine as a whole, and in those cases where the cooling fluid is simultaneously used as fuel gas, the efficiency of the gas turbine is increased at the same time.
  • the nozzle has a circular cross-sectional area has and concentric around the circular cylindrical Input section is arranged. So there is an in The circumferential direction of the input section is more uniform Gap space, which is an even distribution of the cooling fluid flow and therefore even cooling in this area allows.
  • a gas turbine with a combustor arrangement according to the previous Embodiments are also the subject of the invention.
  • Figure 1 is a section of a section a gas turbine with a combustion chamber arrangement according to the invention 1 shown.
  • the combustion chamber arrangement 1 settles together from a large number of individual combustion chambers 3, which are arranged like a wreath and in a common annular gap 13 flow out.
  • the annular gap 13 in turn opens into a turbine chamber 2, in which there are schematically indicated guide vanes and blades of the turbine.
  • Burners 6 are connected upstream of the individual combustion chambers 3. These serve to ignite a mixture of an oxygen-containing Fuel gas and a fuel, which in the Single combustion chambers 3 continue to burn.
  • the single combustion chambers 3 consist of one adjoining the burner 6 Input section 4 and an input section 4 in the direction of the annular gap 13 transition section 5 together.
  • the burners 6 are with the individual combustion chambers 3 connected through an outer turbine housing 7. Starting from the turbine outer casing 7 in the direction of Turbine space 2, a nozzle 8 can be recognized, which concentrically around the circular cylindrical input section 4 of the single combustion chamber 3 extends. Between the nozzle 8 and the input section 4 of the single combustion chamber 3, a gap 9 is left, which by one Cooling fluid can be flowed through.
  • the individual combustion chamber 3 are distributed along the circumference Ribs 10 are formed, with which the individual combustion chamber 3 is supported on the nozzle 8.
  • the ribs 10 are shown in FIG Embodiment molded onto the individual combustion chamber 3, however, they can also be molded onto the connector 8 and extend in the direction of the single combustion chamber 3.
  • a recess 11 can be seen on the side of the nozzle 8, at which an adjacent nozzle of an adjacent Single combustion chamber connects.
  • the individual combustion chambers 3 are to be transferred into a common annular gap 13 the individual combustion chambers at an angle to each other arranged.
  • the distance between the individual combustion chambers starting from the burner 6 in the direction of Annular gap 13 reduced, so that the cylindrical neck 8 from a certain extent in the direction of the annular gap 13 collide.
  • the recesses 11 arranged to further in the nozzle 8 To be able to extend the direction of the annular gap 13 inwards. Adjacent ones lie along the edge of the recesses 11 Stub 8 to each other and can be used to seal each other connected, for example welded.
  • the nozzles 8 arranged according to the invention form with their Gap space 9 a flow channel for a cooling fluid.
  • This in the cooling channel carries cooling fluid guided in a quasi closed manner due to the defined flow channel effectively one convective cooling of the individual combustion chambers 3 in the Nozzle 8 covered area.
  • FIGs 2 and 3 are perspective from different Viewing directions excerpts from trained according to the invention Combustion chamber arrangements shown.
  • the individual combustion chamber 3 at least in the input section 4 surrounding nozzle 8 with the tongue-like extension 12a and 12b shown.
  • Figure 2 is also with help arrows the course of the flow 14 of a coolant fluid from the openly cooled area towards the gap spaces below the tongue-like extensions 12a and shown below the nozzle 8.
  • the tongue-like extensions 12a and 12b towards the exit leading into the gap space from the transition section 5 of the individual combustion chambers 3 rejuvenate. This creates a sufficiently large entrance area guaranteed for the cooling fluid flow.
