Claim:
1. A reheat burner between a high pressure turbine and a low pressure turbine comprising: a flow channel for a hot gas flow with a lance arranged along said flow channel, protruding into the flow channel for injecting a fuel over an injection plane perpendicular to a channel longitudinal axis, wherein the flow 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 flow direction, the mixing zone including changing cross sectional areas by continuous rotation of a non-circular cross section area shape along the longitudinal axis of the mixing zone starting at a first non-circular cross section area shape and ending at an inlet of the low pressure turbine with a non-circular last cross section area shape rotated by an angle between 0 and 180 degrees around the channel longitudinal axis.
