    Abstract: A high pressure gas flare using the Coanda effect has a noise attenuator surrounding the high pressure gas outlet slot. The noise attenuator is in the form of one or more upwardly diverging frusto-conical shields which may be spaced apart or closed with the body of the flare. The attenuator is particularly useful for steam driven flares.

  • Flare
    Patent number: 4486168

The annular gap has an inlet for a fuel gas supply and the upper part of the inner tube has a plurality of channels. The channels are shaped to encourage upward and inward flow of fuel gas so as to mix with air issuing from the outlet of the inner tube.

  • Flare using a Coanda director surface
    Patent number: 4464110
    Abstract: A high pressure gas flare using the Coanda effect and having an internal passageway for low pressure fuel gas has a high pressure gas flow modifier on the outer surface of the Coanda body. The flow modifier may be in the form of one or more projections downstream from the high pressure gas outlet, the projections tending to stabilize the flame.
