- Air-Assist Flares

From

0

Air assisted flares are comprised of two 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 air flow causes turbulence in the waste gas stream, improving mixing, and ultimately combustion efficiency. These flares generally dispose of heavier waste gases which have a greater tendency to smoke.

Air assist flares smokeless dispose of heavier waste gases which have greater tendency to smoke. Air assist flares can be employed at sites where steam may not be available.

Air flare systems are composed of two concentric risers and one or more blowers providing supplemental combustion air. A blower forces air into an outer air annulus where the process gas passes through an inner riser and upon reaching the flare tip, these two streams intermix. This air assist has three principle effects:

  • High-pressure airflow causes turbulence in the waste stream which improves mixing and therefore enhances combustion efficiency.
  • Additional air is induced into the waste gas providing the oxygen necessary for augmented smokeless capacity.
  • Constant airflow creates a cooling effect for extended flare tip service life.

  • High smokeless rates due to superior mixing
  • Capable of burning heavier hydrocarbons smokeless
  • Extended service life
  • Lower operating costs at a given smokeless rate
  • Lower radiant heat at a given capacity
  • Stable, reliable combustion
  • Wide range of flow capacities
