Abstract
A flare tip structure has a tubular component usually mounted at the top of a flare sack which emits waste gas into the atmosphere for disposal by combustion with the aid of one or more pilot burners. Several fluid injectors are mounted inside the component and emit cones of injection fluid, such as natural around the axis of the tubular component. A deflector assists the injectors in creating a cushion of fluid just above the opening of the tubular component to space the combustion flame away from the opening. This allows surrounding air to flow into the gap between the opening and the combustion flame and to mix with waste gas prior to combustion to suppress smoke.
