The FUS Series flare tips are the most efficient flare tips utilizing external steam nozzles in addition to central steam nozzles and are suitable for sites where a general low noise flare tip is required.
The FUS Series tips are based on externally mixing steam and air with the gas at the point of exit, utilizing steam injection nozzles. A ring of FUS nozzles is located at the top leading edge of the flare tip, inside the wind shield.
The steam is discharged from the FUS nozzles entraining large quantities of air into the heart of the gas steam. The gas/air/steam mixture is swirled to entrain large volumes of secondary air resulting in stable combustion condition. This prevents smoke formation from thermal cracking.
The "FUS" nozzles produce very low noise compared with conventional external steam nozzle 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-lick under low gas flow and high wind condition. "FUS" nozzles are self cleaning by virtue of the steam flow carrying foreign matter through the centre orifice.

- Burn-back minimized.
- Energy efficient & reliable pilots
- Continuous Pilot monitoring by means of thermocouple mounted inside the pilot as standard. Optional UV/IR detection available.
- Wind shield supplied as standard.
The FUS series is supplied as standard with a slatted windshield to prevent flamelick and to help cool the top of the flare tip closest to the flame envelop. In order to prevent flame lift off from the tip, the FUS series has unique flame retention lugs positioned at the tip exit of the flare tip.
The unique refractory lining system is secured to tip by heat resistant steel bull horn sprags. Many thousands of fine stainless steel needles are mixed thoroughly with the refractory to reinforce the material evenly over its full depth without producing expansion/contraction shear planes. This refractory installation procedure has been developed and proven over many years to give the longest possible operating life, even in the most arduous conditions.
