Diffusion flame studies of the chemical and physical mechanisms of soot formation from aromatic and substituted aromatic fuels. Progress report, July 15, 1980-February 15, 1981
The opposed co-axial diffusion flame burners have been constructed and preliminary experiments have been conducted, using CO, CH/sub 4/ and hydrogen as fuels. The opposed burners are mounted vertically and can be moved independently or in tandem in the vertical direction and can be moved horizontally to facilitate spatial probing, both optical and chemical. Preliminary flame temperature measurements indicate the temperature can be varied by at least 500/sup 0/K by varying the fuel flowrate and the fuel oxidizer/diluent ratio. A flow regulation system employing critical orifices has been constructed to provide accurate monitoring of the fuel, oxidizer and diluent gases. The critical orifices have been calibrated using helium. The sample probe is being constructed and a number of analytical procedures are being calibrated. The major components of the photon correlation light scattering system have been obtained, tested, and linked together in the experimental configuration. We have scattered light from a simple wicked flame and have obtained good correlation spectra. Preliminary analyses indicated soot particles in 5 to 10 nm range.
