FIELD: heating.SUBSTANCE: invention refers to reheating burner including flow channel for hot gas flow with tube running along the flow channel and protruding into the flow channel for fuel injection into injection plane perpendicular to longitudinal axis of the channel, while the channel and the tube form a swirling area upstream of the injection plane and mixing area downstream of the injection plane long hot gas flow. Mixing area features at least one axial zone with different cross-sections along its longitudinal axis, or with non-round cross-sections taking different positions along its longitudinal axis by continuous rotation around longitudinal axis.EFFECT: burner operating at higher temperatures with reduced NOx and CO emission.13 cl, 12 dwg |
