Abstract
A burner configuration with primary and secondary pilot burners is described. The burner configuration is used in a firing installation, in particular a gas turbine combustion chamber, and has a main burner and, disposed centrally within it, a primary pilot burner used for igniting and/or for stabilizing the combustion of the main burner. For additional stabilization, for reducing rumble noises in the firing installation and for avoiding the possible flashback of the flame in a partial region of the burner, which can then sometimes occur, a plurality of outlet openings, which together form a secondary pilot burner, are disposed in the outlet region of the main burner. The flames of the secondary pilot burner surround the main flame like a ring and additionally stabilize the operation under different load conditions.
