Abstract (en)
[origin: EP0592717A1] In a gas-operated premix burner for the combustion chamber of a gas turbine, the fuel which is injected via a large number of nozzles (17) is mixed intimately together with the combustion air prior to ignition inside a premix space (21). The nozzles are arranged around a burner axis (10). For the selective influencing of the fuel profile at the outlet of the burner, the fuel concentration in the region of the burner axis is kept greater than the average fuel concentration in the outlet plane (22) of the burner. To this end, additional fuel nozzles (23) are provided in the region of the burner axis (10). The additional fuel nozzles (23) can be fed via a separate fuel line (24). <IMAGE>
