Description

ABSTRACT:
A method and an appliance are described for supplying fuel to a premixing burner for operating a gas turbine, which premixing burner has at least one burner shell (1, 2) at least partially bounding an axially extending premixing burner space, having a premixing gas supply directed into the premixing burner space via the burner shell (1, 2), the premixing gas (6) being mixed with combustion inlet air and being ignited downstream external to the premixing burner,The invention is characterized by the fact that the premixing gas supply is carried out separately by means of at least two spatially axially separated regions (S1,S2) along the burner shell (1, 2), having a region (S1), which is arranged upstream, and at least a second region (S2), which is arranged downstream, by the fact that more than 60% of the total premixing gas supply takes place via the first region (S1) in order to start the gas turbine, and by the fact that a stepwise or continuous redistribution of the premixing gas supply to the second region (S2) takes place for the further run-up of the load on the gas turbine to full load.
