The results clearly show that Main air tremendously has an effect on the burner flame sample and steadiness. Without having a ring, the flame is brighter and shorter, with a rise in primary air (PA) approximately seventeen%, and blows out at 20% PA or better. During the presence of a hoop, the flame turns into unstable and blows out if the ring is positioned close to the burner, however it is much more stable in the event the ring is put from the burner.
