Abstract (en)
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 (GC) for supplying a stream of oxygen containing gas (OCG) to the main combustion zone (MCZ) through a gas channel exit (GCE), which gas channel (GC) is confined by channel walls (CW). To enhance especially stability it is proposed to provide said gas channel (GC) 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 (APE), wherein downstream said minimum throat diameter (MTD) the radial outer channel wall (OCW) defines an increasing channel diameter.
