Air-Assisted Flares

FlareTech Inc. offers two main types of Air-Assisted Flares.

Designed to dispose of heavy hydrocarbons that would otherwise create smoke during the combustion process, Air-Assisted Flares use blowers to introduce ambient air directly into the waste gas stream as it exits the flare tip.

We use this introduction of ambient air, along with turbulence and stabilizing, to ensure a thorough air/fuel mixture while also stabilizing the flame.  The waste gas and air, once ignited, must be together for enough time and at sufficient temperature, and be thoroughly mixed via turbulence to ensure no smoke is produced and a high destruction efficiency is maintained.

All of FlareTech’s Air-Assisted Flare Stacks are designed to be the most efficient and dependable flare systems on the market. FlareTech designs and manufactures two models of Air-Assisted Flare Systems; the A.I.R. Flare Stack Tip and the S.L. Flare Stack Tip for a wide variety of low-pressure or high-pressure flaring applications.

The S.L. Air-Assisted Flare Tip flows the waste gas through a series of slotted diffusers at the tip where it is mixed with the air stream being provided from the blower(s). The blower pulls in ambient air and forces the air up the air duct between the waste gas diffusers, to mix with the waste gas and air at the exit of the flare tip.

Each diffuser is provided with multiple flame stabilizers to ensure there is no chance of a helicopter affect occurring (low frequency rumble).

The S.L. Air-Assisted Flare Tip is available in a wide variety of stainless steel with 316L and 310 being the most common.

The A.I.R Air-Assisted Flare Tip has an internal pipe (waste gas riser) which delivers the waste gas to the tip; the outer pipe transports the air from the blower where it is forced into the waste gas stream. The ring at the tip of the flare stack directs the air into the waste gas stream creating efficient mixture of the waste gas and air for stable smoke free combustion.

The A.I.R. Air-Assisted Flare Tip design is utilized for low flow rates of waste gas that have a low exit velocity waste gas that will smoke. With this design, existing Utility Flare Tips on low pressure flares can be modified without affecting the pressure drop of the existing flare system. This tip design can also be utilized on high pressure flares that have a secondary source of low pressure waste gas that requires air to stop smoke from forming.

Our technologists have many years of experience and will assist you in ensuring the proper design is chosen to suit your site specific conditions. Each flare is custom designed to meet your requirements.
