Sonic flares (Variable Slot Orifice)

Also known as a Coanda flare, this state-of-the-art flare tip automatically adjusts the flare tip opening as the flow increases and decreases. At low flow, the variable orifice is almost completely closed. As the flow and backpressure increase, the flare tip orifice opens. This variable orifice technology allows the tip to maintain a high exit velocity at low flow rates as well as high flow rates to achieve maximum air mixing to achieve 100% smokeless performance.

The variable orifice sonic tip is a economical solution to other smokeless technologies such as air-assisted flares when a minimum of 30 psig waste gas pressure is available.
