ABSTRACT:
In a combustion chamber consisting essentially of an inflow zone (5) and a combustion zone (11) and having self-ignition, the inflow zone (5) has vortex generators (100), of which a plurality are arranged next to one another over the periphery of the duct through which flow occurs. A premixing zone (7) follows downstream of the inflow zone (5), into which premixing zone (7) a gaseous and/or liquid fuel (9) is injected as secondary flow into a gaseous main flow (4). Between premixing zone (5) and the downstream combustion zone (11), the transition is characterized by a jump (12) in cross-section which induces the initial cross-section of flow of the combustion zone (11). The fuel (9) is injected via a number of fuel lances (8) distributed over the periphery, the fuel (9) being enriched here with a portion of assisting air
