Steam assisted flares are flares designed to dispose of heavier molecular weight gases which have a tendency to smoke. In order to prevent smoke formation, steam is injected into the waste stream using peripheral steam rings, center stream spargers and/or inner induction tubes. Steam flares are used in applications where high pressure steam is available on site. Steam flares are typically found in downstream applications where high efficiency combustion of heavily hydrocarbons is required.
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.
