The research objective was to design instrumentation and evaluate its feasibility for characterizing flame turbulence and temperature gradient for several burner configurations. In this way, it may be possible to relate basic flame characteristics to the generation of emissions, particularly NO which is formed and fixed in the primary combustion zone. The feasibility of recording fog-free holographic interferagrams of residential fuel fired oil burner flames was demonstrated with two holocameras designed to observe the near and far field of the burner. The most important feature observed interferometrically was that the flame structure is extremely turbulent. This turbulence made it impossible to resolve the fringe pattern on the centerline of the burner. Barewire thermocouple measurements made of the flame were corrected for radiation. Excellent quality holographic interferograms were recorded of a small burner (Bernzomatic burner). Recording a holographic interferogram of a hot air gun showed the feasibility of controlling the turbulence level of a flame-like hot gas. Preliminary data were also reduced in this case. (Author)
