Abstract (en)
[origin: EP2037172A2] Main-fuel injection (18) has central recesses (23) for controlled inhomogeneous fuel injection, especially in a peripheral direction. Their number on the periphery amounts to between 8 and 40 and, in a peripheral direction, they have a delta 2 setting angle of 10[deg] = delta 2 = 60[deg] and a delta 1 axial setting angle opposite a burner's axis between -10[deg] = delta 1 = 90[deg] . The central recesses are arranged in a single row, in multiple rows or in a zigzag layout.
