Abstract

See full text

A burner of a gas turbine extending along an axis is provided having in axial order: a swirler section, mixing section, outlet section, and main combustion zone. The swirler section has swirler vanes to swirl a stream of fuel and oxygen containing gas entering therein in a circumferential direction. The mixing section conducts the premix of fuel and oxygen containing gas to the outlet section. The outlet section discharges the premix into the combustion zone expanding the flow of premix from a smaller axial cross section of the mixing section to a larger cross section of the combustion zone which streamlines the flow to diverge radially. A surface of the outlet section facing the flow of the premix is provided with first fuel nozzles injecting fuel into the premix into a radial inwardly inclined direction before the flow of the premix enters the outlet section into the combustion zone.
