Abstract (en)

[origin: EP0777084A2] The mixing device has a burner tube, a coaxial centring hub (22) to receive the burner jet shaft (26). It has an air input tube round the jet shaft with fuel jet (30), ending downstream in a conical air jet, vortex-forming wings (40) in the air input tube, and an annular disc (20) to close the air input tube. The centring hub is fitted upstream of the annular disc, and is aligned with the central jet aperture of the disc. The air input tube is downstream of the annular disc, which has air passage apertures between the hub and the tube. The vortex forming wings are downstream of the air passage apertures, projecting into the tube.
