Explanation
This is a close up picture of premixed methane-air Bunsen flame with addition of carbon particles. The soot generator device is used to produce agglomerated particles from high-purity graphite. The size of particles is from 20 nm to 150 nm. The diameter of the burner is 7 mm. The flow velocity is 1.5 m/s, and the equivalence ratio is 0.9. It is observed that carbon particles are heated and burned when they pass though the flame front.
The word “GOZINKA” means the volcanic eruption, which is the holy flame in Japan. In this picture, the flame is reflected on the surface of the burner, which just looks like reflecting of eruption volcano on the surface of the lake in the fantastic atmosphere.
