Abstract:
A gas-turbine lean combustor includes a combustion chamber (2) and a fuel nozzle (1) which includes a pilot fuel injection (17) and a main fuel injection (18). The main fuel injection (18) includes central recesses (23) for a controlled inhomogeneous fuel injection, the number of said recesses on the circumference ranging from 8 to 40 and said recesses having an angle of inclination δ2 in circumferential direction of 10°≦δ2≦60° and an axial angle of inclination δ1 relative to the combustor axis (4) between −10°≦δ1≦90°.
