AEE 334 EXPERIMENT #3: FLAME STABILITY AND FLAME SPEED Objective: The aim of this experiment is to observe yellow tipping, lift off and light back of the flame, and to measure the flame speed and observe the change of flame speed at different air to fuel ratios. Theory of Flame Stability: There are several well-defined areas of operation for a burner that operates on gaseous fuels. The three regimes may be distinguished as follows: a) Yellow Tipping: When the airflow to burner is prevented, the flame will have a yellow tip and may produce smoke. When the airflow is increased, yellow tip disappears and is replaced by a blue non-luminous flame. b) Lift Off: When the airflow to burner is gradually increased with a constant gas flow, if sufficient gas flow exists, the yellow tipping will disappear and blue flame will be established. Further increase in airflow will result in the lifting of the flame around the surface of the burner. At this moment, the velocity of mixture leaving the burner
