Air Assist technology is a proven method to achieve smokeless combustion of gas steams. The flare gas and air flow to the flare tip where they mix. The air assist blower provides a portion of the stoichiometric air required for combustion at high velocity which generates sufficient turbulence for mixing thus eliminating smoke formation.
The combustion air comes from a centrifugal or axial blower mounted near the bottom of the flare. Small production flares can use a 3-5 HP blower, while large custom air flares may require multiple blowers up to 150 HP each.
A properly operated air flare will achieve a destruction efficiency of greater than 98% and will meet the design requirements of 40 CRF 60.18.
