A burner with one swirler generally keeps a round cross-section. A burner containing a plurality of swirlers may have any cross-section it is generally circular or rectangular. Usually a plurality of burners was organized coaxially across axis of a gas turbine.
Relating to one embodiment a plurality of gasoline nozzles is actually distributed in said upstream third associated with period of the swirl vane calculated over the swirl axis, most preferably just during the upstream one-fourth of mentioned duration
In a preferred embodiment the burner under full-load injects gas from the sucking part or even the stress part of at least one, better of swirl vanes.
