A reheat burner () includes a channel () with a lance () protruding thereinto to inject a fuel over an injection plane () perpendicular to a channel longitudinal axis (). The channel () and lance () define a vortex generation zone () upstream of the injection plane () and a mixing zone () downstream of the injection plane () in the hot gas (G) direction. The mixing zone () includes a high speed area () with a constant cross section, and a diffusion area () with a flared cross section downstream of the high speed area () in the hot gas (G) direction.

Reheat burner

A reheat burner includes a channel with a lance projecting thereinto to inject a fuel over an injection plane perpendicular to a channel longitudinal axis. The channel and lance define a vortex generation zone upstream of the injection plane and a mixing zone downstream of the injection plane in the hot gas direction. The mixing zone has a cross section with diverging side walls in the hot gas direction. The diverging side walls define curved surfaces in the hot gas direction having a constant radius.
