Plants that require smokeless flares where steam is not preferred use our state-of-the-art, air-assisted flare systems for cost-effective, smokeless flaring.
Our long-lasting flares use a range of innovative techniques to optimize air-to-gas mixing and eliminate steam-energy costs. These innovative designs are used to optimize flaring performance from small, simple applications to large, complex designs and everything in between. Air-assisted flares can be used as a first-stage flare in multi-flare arrays designed to meet high capacity needs.
The AZDAIR™ air-assisted flare delivers safe, smokeless operation in virtually all conditions—from maximum to minimum purge flow—without steam or support fuels. An effcient mixing design maximizes the system’s gas-to-air interface. providing maximum smokeless capacity with minimal air blower requirements.
A signifcant difference between the AZDAIR and conventional air-assisted flares is the design of the gas riser. Conventional flare designs utilize an internal gas riser that runs concentric to the outer air riser in the flare stack. This can have several unintended consequences including:
+ Diffcult lifting/welding procedures for installation
+ Flare gas condensation in the air-cooled internal gas riser can lead to burning rain and smoke
+ In cold or hot service, the gas riser can contract or expand, leading to ineffective ignition of the flare gas with the pilots
The AZDAIR flare utilizes an external gas riser to eliminate these problems. This simplifes installation of the flare stack and provides for more reliable ignition and smoke control.
