Statistical Analysis of Flame Oscillation Characterization of Oxy-Fuel in Heavy Oil Boiler Using OH Planar Laser-Induced Fluorescence

Figure 2

Selected sequences of OH-PLIF images. (a) In the O₂/N₂ atmosphere, the oxygen concentration is 33% corresponding to the condition A1; (b) in the O₂/CO₂ atmosphere, the oxygen concentration is 33% corresponding to the condition A2; (c) in the O₂/CO₂ atmosphere, the oxygen concentration is 37% corresponding to the condition A3. The unit scale bar reflects the intensity of the OH signal, which has been normalized.
