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.
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.
The Peacock Burner was developed to flare liquid hydrocarbons without liquid fallout or soot formation (smoke). These burners provide excellent service for well testing operations and have been used in applications in the Gulf of Mexico and Arabian Gulf. When only oil is flared, a high pressure air or gas source is required to provide mechanical atomization which ensures the mixture is a fine mist as it exits the burner nozzle. This particular burner nozzle is designed to accept separate high pressure oil and air/gas streams. for maximum efficiency.
Mach-1 Sonic Flares are used in both onshore and offshore applications to dispose of high pressure waste gas streams with high smokeless capacities. By efficiently inducing high volumes of ambient air for more complete, smokeless combustion at sonic velocities, this advanced flaring technology allows for reduced levels of radiation, and can be placed at lower, less visible elevations, allowing for a more cost-effective flaring solution. Mach-1 sonic flare technology can be applied in multi-point orientations which accomodate flame length restrictions.
The VariMach sonic flare tip features spring-actuated variable sonic nozzles that allow the exit area to vary with pressure, ensuring constant sonic velocity of waste gas. This industry-proven technology guarantees sufficient inspiration of air to ensure 100% smokeless combustion and infinite turndown. Radiation levels are also minimized throughout the entire range of flow, yielding shorter stack heights and reducing material costs. Additionally, the VariMach has the lowest purge rate of any flare technology on the market, minimizing utility costs while maintaining flashback protection.
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.
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.
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.
