ABSTRACT:
The invention relates to a main-burner arrangement of a combustion chamber (5), in particular for a gas turbine, at least two main-burner groups (13.1, 13.2), each comprising at least one burner (13) of the same size and geometry being provided for the purpose of equipping the combustion chamber (5), and at least one main-burner group representing the normal main burner(s) (13.1), the normal main burner(s) (13.1) producing a homogeneous flame front in the combustion chamber (5), and the other main-burner group interfering as an interference burner or burners (13.2) with the homogeneity of the flame front in the combustion chamber (5). In this burner arrangement, the interference burner(s) (13.2) is/are arranged in the combustion chamber (5) so as to be inclined or axially displaced in relation to the normal main burner(s) (13.1). This interferes with the symmetry and homogeneity of the flame front. The power of the combustion chamber is increased and pressure pulsations can be avoided.
