Flame Ring Flares 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 properly designed 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.
