ABSTRACT:
In the case of a combustion chamber which is respectively arranged upstream of and downstream of a fluid-flow machine and which essentially comprises an inflow duct (5) and a downstream premixing and combustion zone (5a), a fuel (11) is injected into the combustion air (4) coming from the fluid-flow machine acting upstream after the combustion air (4) flows through vortex generators (200). The injection (7a, 7b) of the fuel (11) into the premixing and combustion zone (5a) is effected in varying direction and quantity. The hot gases from the combustion of the aforesaid mixture form a temperature-graduated front (8), the minimum temperature of which corresponds fluidically with the base of the blades to be acted upon of the fluid-flow machine (2) . arranged downstream. The fuel (11) can be assisted with assisting air (12).
