Abstract: Gas turbine burner The present invention refers to a gas turbine burner (GTB) comprising: - a main combustion room (MCR) containing a main combustion zone (MCZ) for burning a mixture of air and fuel (AFM), - at least one gas channel for supplying a stream of oxygen containing gas to the main combustion zone (MCZ) through a gas channel exit, which gas channel is confined by channel walls. To enhance especially stability it is proposed to provide said gas channel with at least one radial protrusion (RP), extending at least along a part of the circumference and continuously reducing the diameter of the axial exit throat segment (AETS) in downstream direction down to a minimum throat diameter (MTD) at a downstream axial position with regard to the axial plane of said radial inner channel wall (ICW) end, wherein downstream said minimum throat diameter (MTD) the radial outer channel wall (OCW) defines an increasing channel diameter.

Abstract: The present invention refers to a gas turbine burner (GTB) comprising : a main combustion room (MCR) containing a main combustion zone (MCZ) for burning a mixture of air and fuel (AFM), at least one gas channel for supplying a stream of oxygen containing gas to the main combustion zone (MCZ) through a gas channel exit, which gas channel is confined by channel walls, at least one fuel injection element (FIE) protruding from the channel wall, comprising an inner cavity (IC) being supplied with fuel (F), which inner cavity (IC) joins into at least one nozzle opening (N01, N02) of at least one nozzle (NO) of said at least one fuel injection element (FIE) to inject fuel (F) into the gas channel. To enhance especially stability and efficiency and to lower emissions it is proposed to provide said gas channel with at least one swirler wing (SW) to imprint a certain velocity distribution on the gas flow through said gas channel and wherein said at least one fuel injection element (FIE) itself is made as said at least one swirler wing (SW).
