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.

Turbomix Air-assist Flares (TMA)

Turbo-Mix Air Assisted flares are comprised of two tandem risers (waste gas and air) and a blower system that provides supplemental combustion air. In contrast to the Slot Flow Air Assist Flare Design, the TMA employs tandem air and gas risers to provide a more economical flare package when a large quantity of smokeless air is required. Mixing of waste gas and combustion air at the flare tip exit optimizes mixing and ultimately improves combustion efficiency. Turbo-Mix Air Assisted flares generally dispose of heavier waste gases which have a greater tendency to smoke.

Steam Assisted Flares

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.
