Description

  

      Gasturbinenanlage.       Die Erfindung betrifft eine Gasturbinen  anlage und besteht darin, dass die Kühlluft  in einem zum Brennraum konzentrisch lie  genden     Mantel    an dem Brennraum entlang  geführt wird und zum Teil durch mehrere,  am Umfang des     Brennraumes    verteilte Öff  nungen in den Brennraum eintritt, während  ein zweiter Teil der Kühlluft am Ende des  Brennraumes durch     Verwirbelungsvorrichtun-          gen        den;

      Brenngasen beigemischt und ein  dritter Teil, der die Treibgasleitung mantel  artig umgibt, bis zum Eintritt in die Tur  bine weitergeführt     wird.    Auf diese Weise       wird    die Kühlluft intensiv ausgenutzt.  



  In der Zeichnung ist eine beispielsweise  Ausführungsform des Erfindungsgegenstan  des schematisch dargestellt.  



  Der Verdichter 1 drückt die verdichtete  Luft in die Brennkammer 2, wo sie sich teilt.  Während ein Teil     unmittelbar    als Verbren  nungsluft vorn in den Brennraum 3 der       Brennkammer    strömt, wird die Kühlluft  aussen als Mantel an diesem Raum 3 entlang  geführt und tritt zum Teil durch am Umfang    des Brennraumes 3 verteilte     Öffnungen    4 in  den     Brennraum        ein,    zum Teil strömt sie am  Ende des     Brennraumes    durch besondere     Ver-          wirbelungsvorrichtungen    5 - und wird den       Brenngasen    beigemischt, die zur Turbine 6  strömen,

       um    dort     unter    Energieabgabe ent  spannt zu werden, während ein dritter Teil  der Kühlluft als Aussenmantel 7 der     Brenn-          gasleitung    bis zum Eintritt in die Turbine  weitergeführt     und    sowohl den Füssen der  Laufschaufeln bei 8 als auch denen der     Leit-          schaufeln    bei 9 zugeführt wird, so dass Füsse  und Spitzen von Lauf-     und    Leitschaufeln ge  kühlt werden.



      Gas turbine plant. The invention relates to a gas turbine system and consists in the fact that the cooling air is guided along the combustion chamber in a jacket that is concentric to the combustion chamber and enters the combustion chamber in part through several openings distributed around the circumference of the combustion chamber, while a second part of the Cooling air at the end of the combustion chamber through turbulence devices;

      Combustion gases are mixed in and a third part, which surrounds the propellant gas line like a jacket, is continued until it enters the turbine. In this way, the cooling air is used intensively.



  In the drawing, an example embodiment of the subject invention is shown schematically.



  The compressor 1 pushes the compressed air into the combustion chamber 2, where it divides. While a part flows directly as combustion air into the combustion chamber 3 of the combustion chamber at the front, the cooling air is guided outside as a jacket along this chamber 3 and partly enters the combustion chamber through openings 4 distributed around the circumference of the combustion chamber 3, and partly it flows at the end of the combustion chamber by special swirling devices 5 - and is mixed with the combustion gases that flow to the turbine 6,

       in order to be released there while releasing energy, while a third part of the cooling air is carried on as the outer jacket 7 of the fuel gas line to the inlet into the turbine and is fed to both the feet of the rotor blades at 8 and those of the guide vanes at 9, see above that the feet and tips of blades and guide vanes are cooled.
