Fus Series

External steam nozzle, smokeless low noise FUS Series.

The FUS/ Series flare tip is the most efficient flare tip utilising external steam nozzles and is suitable for sites where a general low noise flare tip is required.

The FUS series tip is based on extremely mixing steam and air with the gas at the point of exit, utilising steam injection nozzles. A ring of FUS nozzles is located at the top leading edge of the flare tip, inside the wind shield.

This steam is discharged from the FUS nozzles entraining large quantities of air into the heart of the gas stream. The gas/ air/ steam mixture is swirled to entrain large volumes of secondary air resulting in stable combusion conditions. This prevents smoke formation from thermal cracking.

The "FUS" nozzles produce very low noise compared with conventional external steam nozzles design. The swirling non-converging action of the steam from the "FUS" gives maximum air entrainment and shapes the flame to avoid overheating of the tip. This also helps in preventing flame-click under low gas flow and high wind conditions. "FUS" nozzles are self cleaning by virture of the steam flow carrying foreign matter through the centre orifice.
