When smokeless flaring is desired and neither steam nor assist gas is available, blowers can be
used to inject combustion air directly into the waste gas stream as it exits the flare tip. The
ZEECO AF air assisted flare tip incorporates a proprietary design that splits the waste gas
stream into several smaller streams at the top of the flare to increase the gas / air contact
surface area and promote better mixing. This key design feature maximizes the waste gas / assist
air mixing while minimizing the amount of forced air required and resultant blower horsepower.
Forced air from the blowers and gas from the flare header are routed separately from the base of
the flare stack to the top of the flare. At no point do the air and gas mix prior to leaving the
flare tip, ensuring the safety of the system. In addition, with this design concept, any ZEECO
AF air assisted flare can operate without the blowers being on and provide for safe disposal of
the waste gases in the event of a power outage. The Series AF flare tip produces a superior
quality flame, which stays erect during all atmospheric and flow conditions. Flame lick on the
exterior of the flare and burnback inside the flare tip, are virtually eliminated by the forced
air from the blowers, which create a strong upward velocity, making the impact from the wind
minimal in shaping or moving the flame. The forced air also shortens the flame length and
reduces radiation at grade by ensuring a very aerated mixture at the exit of the flare tip.
