Patent ID: 7003960

Claim:
A method for supplying fuel to a premixing burner for operating a gas turbine, the premixing burner having at least one burner shell which at least partially bounds an axially extending premixing space, and a premixing gas supply directed into the premixing space via the burner shell, the premixing gas being mixed with combustion inlet air in the premixing space and being ignited downstream, external to the premixing burner, and the premixing gas supply being carried out separately by at least two spatially axially separated regions along the burner shell, including a first region which is arranged upstream, and at least a second region which is arranged downstream, the method comprising: supplying more than 60% of the total premixing gas via the first region to start the gas turbine; and supplying a stepwise or continuous redistribution of the premixing gas to the second region for the run-up of the load on the gas turbine to full load.
