Abstract
Bei einer Brennkammer (13,14,18,22) für eine Gasturbine, in welcher Brennkammer (13,14,18,22) Brennstoff mit einem in die Brennkammer (13,14,18,22) eintretenden Luftstrom (10) vermischt und anschliessend verbrannt wird, und der entstehende Verbrennungsluftstrom (33) stromab der Brennkammer (13,14,18,22) einer Turbine zugeführt wird, wird ein schnelles und effizientes Vermischen von Luftstrom und Brennstoff dadurch bewirkt, dass die Brennkammer (13,14,18,22) einen ringförmigen Diffusor (13) aufweist, in welchen der Luftstrom (10) eintritt, dass stromab des Diffusors (13) und mit diesem in Verbindung stehend mindestens eine im wesentlichen ringförmige toroidale Kammer (14) angeordnet ist, dass stromab der ringförmigen toroidalen Kammer (14) und über deren Umfang verteilt Mischröhren (22) abzweigen, und dass stromab der Mischröhren (22) ein ringförmiger Brennraum (18) angeordnet ist, in welchen die Mischröhren (22) einmünden. In a combustion chamber (13, 14, 18, 22) for a gas turbine, in which combustion chamber (13, 14, 18, 22) fuel is mixed with an air stream (10) entering the combustion chamber (13, 14, 18, 22) and is then burned and the resulting combustion air flow (33) is fed to a turbine downstream of the combustion chamber (13, 14, 18, 22), the air and fuel are mixed quickly and efficiently by the combustion chamber (13, 14, 18 , 22) has an annular diffuser (13), into which the air flow (10) enters, that at least one essentially annular toroidal chamber (14) is arranged downstream of the diffuser (13) and in connection therewith, that downstream of the annular branch off the toroidal chamber (14) and mixing tubes (22) distributed over its circumference, and that an annular combustion chamber (18) is arranged downstream of the mixing tubes (22), into which the mixing tubes (22) open.
