A method is developed to estimate asymmetrical flame structure (profiles of temperature, soot density and CO_2 partial pressure) in flame containing soot from transmission and emission data. This method considers self-absorption of radiation by CO_2 and soot. It needs radiation measurements at two wavelengths. One is the wavelength at which monochromatic absorptivity of CO_2 is almost 0 and only soot absorbs radiation. The other is the wavelength in which both CO_2 and soot absorb radiation. Using these radiation data, flame structure can be reconstructed. In this paper, using the radiation data simulated from assumed flame structure, flame structure was reconstructed. When the distribution of temperature was assumed to be uniform and random error within ±0.5% is added to the simulated radiation data, standard deviation of the estimated flame temperature is 6.3 K.
