Abstract (en)
In a gas turbine combustion chamber in which cooling is performed by combinations of convective heat transfer mechanisms, the basic principle of which is heat dissipation by flow, the transition from the convective cooling duct (4) to the plenum ahead of the burners (5) is designed as a small diffusor (6). The total pressure loss in the overall system is thereby reduced and this leads to improved efficiency. <IMAGE>

Bei einer Gasturbinenbrennkammer, bei welcher zur Kühlung Kombinationen von konvektiven Wärmeübertragungsmechanismen verwendet werden, deren Grundprinzip die Wärmeabfuhr durch Strömung ist, ist der Übergang vom Konvektivkühlkanal (4) zum Plenum vor den Brennern (5) als Kleindiffusor (6) ausgebildet. Dadurch wird der Totaldruckverlust im Gesamtsystem vermindert, was zu einem verbesserten Wirkungsgrad führt. <IMAGE>
