Gas turbine annular combustion chamber having radially displaced groups of oppositely swirling burners.

An annular combustion chamber of a gas turbine, comprising:

• an inlet front wall;
• a plurality of premixing burners arranged on the front wall so that outlets of the burners are on a single plane, all of the burners being positioned in circumferentially adjacent groups of at least two burners, the burners in each group being radially aligned on the front wall, each group including at least an inner burner and an outer burner, wherein the burners are configured to produce a swirl having a direction of rotation, the inner burners having one swirl direction, the outer burners having a swirl of one direction opposite to that of the inner burners, wherein adjacent groups of burners are alternately positioned radially outward and radially inward relative to each other;
• and
• means for operating the burners as one of piloting burners and piloted burners.
