摘要： The reheat burner (1) comprises a channel (2) with a lance (3) projecting thereinto to inject a fuel over an injection plane (4) perpendicular to a channel longitudinal axis (15). The channel (2) and lance (3) define a vortex generation zone (6) upstream of the injection plane (4) and a mixing zone (9) downstream of the injection plane (4) in the hot gas (G) direction. The mixing zone (9) has a cross section with diverging side walls (20) in the hot gas (G) direction. The diverging side walls (20) define curved surfaces in the hot gas (G) direction having a constant radius (R).
