- a primary injection device is also arranged upstream of the catalytic converter, which is used to inject a fuel into the outer ring channel.
- the known burner with radially arranged catalysts and radial arranged injection devices equipped via a radial inflow is realizable in the combustion chamber.
- the present invention addresses the problem for a burner type mentioned above to provide an improved embodiment, in particular increases the stability of the combustion in the combustion chamber.
- the invention is based on the general idea of designing the burner in such a way that the flow flowing through the catalyst at least when it enters has a swirl in the combustion chamber.
- the catalyst exiting flow with a swirl can be in the combustion chamber support the formation of a central recirculation zone. This Recirculation zone leads to anchoring of the flame front in the combustion chamber and thus to stabilize the combustion process.
- a further development is particularly advantageous in the ring channel and combustion chamber are coordinated in terms of their dimensions so that the Transition from the annular channel to the combustion chamber has a cross-sectional expansion is. This measure allows the swirl flow when entering the Combustion chamber practically burst, which creates additional stabilization for the central recirculation zone results.
- a swirl generating device arranged in the ring channel can expediently be used positioned directly at the transition between the ring channel and the combustion chamber his. With this measure, the swirl flow occurs immediately after its generation the combustion chamber, which reduces friction losses.

- the secondary injector 3 can be designed so that - as here - the fuel centrally and essentially parallel to the longitudinal axis 30 into the combustion chamber 2 brings. Additionally or alternatively, the secondary injection device 3 also be designed so that the fuel is transverse or inclined to the longitudinal axis 30 and / or laterally into the combustion chamber 2.
- the catalytic converter 5 can be designed, for example, as a ceramic monolith, which is coated with a catalytically active substance. It is also possible the catalyst 5 by suitable layering or stacking one or more to build folded or corrugated sheets, with a corresponding Orientation of the folds and corrugations channels arise that the catalyst 5 penetrate. By a suitable coating of the sheets with a catalytic active material can be catalytically active channels and catalytic inactive Channels are formed. Catalysts that are constructed in this way are known for example from US 5 202 303. In the embodiments of the 1 and 2, the catalyst 5 by a spiral winding or several corresponding sheets are formed, which are appropriate to the Secondary injector 3 are wound. In the embodiment according to 3, the sheets for forming the catalyst 5 on a tube 8 be wound, which delimits the annular channel 4 radially inwards.
- the swirl generating device 6 acts on the one flowing through the catalytic converter 5 Flow with a swirl.
- the swirl generating device 6 can as here have a swirl generator 9, which forms a separate component.
