WebVery high tip velocities cause a phenomenon known as blow-off, in which the flame front is lifted and could eventually turn into a blowout. Very low velocities could damage the flare tip owing to high heat intensities and smoking. In this case, ingress of air in the system and creation of a flammable mixture are possible.
