Abstract
A burner for burning a hydrogen-containing fuel is equipped with a burner unit which comprises a fuel feed and a feed for a primary oxidant (oxygen) and which is accommodated in a feed for a secondary oxidant (air). A swirl device whose relative position with respect to the burner unit can be altered is provided in the feed for the secondary oxidant. The relative position of the burner unit and the swirl device may be controlled according to a composition of the fuel, in particular according to the water content thereof and the ratio of primary and secondary oxidant. The burner allows flexible adaptation of the burning to fuels of different composition, even during ongoing operation.
Claims15
A burner for combustion of a hydrogen-containing fuel, the burner comprising:
- a burner unit which is accommodated within a feed for a secondary oxidant and comprises a fuel feed connected to an inlet for a hydrogen-containing fuel and a feed for a primary oxidant;
- and
- a swirl device disposed in the feed for the secondary oxidant;
- wherein upstream of the fuel feed of the burner unit is a mixing zone into which opens the inlet for hydrogen-containing fuel and at least one inlet for a second gaseous fuel;
- and
- wherein the swirl device is accommodated within the feed for the secondary oxidant so as to be movable axially with respect to the feed for the secondary oxidant and with respect to the burner unit.
