GENERAL DESCRIPTION

Utility flares are one of the most common and basic flare designs. Utility flares are employed in applications that do not require smokeless burning or in applications where smokeless flaring can be achieved without the use of an additional assist medium.  Utility flares therefore, do not require auxiliary gas streams such as steam or air; two fluids normally used to improve smokeless capacity.  These flares are typically accompanied by a Dynamic Seal in the base of the tip to reduce purge gas costs and prevent flashback.  Additionally, the Flare Industries’ Utility Tip incorporates a flame retention ring to eliminate flame lift-off and provide stable, reliable combustion.

Flame Ring Flares (Low Heating Value)

Carbon dioxide is often used in fire extinguishers and snuffing systems with the intention of effectively extinguishing flames. When CO2 gas is a large percentage of a waste gas stream, at times it proves difficult to maintain a lit flare, without the use of assist gas or a flame ring. Flare Industries’ industry-proven Flame Ring Flare Technology is recommended in low-BTU applications such as those involving large quantities of CO2 gas. A circumferential ring of fire at the flare tip provides stable, reliable ignition and prevents potential auto-suppression of the flame in these low-BTU applications.

Slot-Fow Ais-Assist Flares (SFVP)

Slot Flow Air Assisted flares are comprised of two concentric risers (waste gas and air) and a blower system that provides supplemental combustion air. Air is fed by the blower into the air riser, to combine with the process gas, which passes through its own secondary riser. Upon mixing, the high-pressure airflow causes turbulence in the waste gas stream, improving mixing, and ultimately combustion efficiency. SFVP flares generally dispose of heavier waste gases which have a greater tendency to smoke.

Sonic Flares – AirMach

The AirMach flaring system was developed to specifically address the problems associated with sonic velocity flares operating at sub-sonic flow rates.  Sonic flares operating at sub-sonic exit velocities will smoke when heavier waste gas flows are present.  The AirMach provides smokeless flaring performance at lower flow conditions utilizing a blower for combustion air. In this application,  the AirMach operates as a traditional air-assist flare.
