The FUS Series flare tip is an efficient flare tip for smokeless combustion which utilizes steam nozzles for smoke suppression. It is suitable for sites where a low noise flare tip is required.
The FUS Series tip externally mixes the 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.
The 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 combustion conditions. 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 conditions. "FUS" nozzles are self cleaning by virtue of the steam flow carrying foreign matter through the centre orifice.
