Soot particles in flames are remarkably important as a means of increasing the radiant emissivity to enable the combustion energy of the hydrocarbon fuel to be transferred more rapidly from the flame to the surface to be heated in the combustors. From the point of view of smoke emission from stack however small soot particles are easily injected deep into the respiratory system, they are greatly hazardous to human health. The understanding of the soot particle size and concentration in flames are necessary to predict the problem both to flame radiation and to air pollution. In support of this work, we believe that light scattering technique is one of advantageous methode. The main subject of this paper are to basic investigate the calculated scattered light intensities at various angles from the incident beam with the predictions from light scattering theory for spheres due to G. Mie and to try a preliminary experiments by water suspensoids of polystyrene latex particles having diameter of 0.091 and 0.176μ. The results obtained are as follows: (1) Good agreement between experiment and Mies theory is found, when concentration of water suspensoids of polystyrene latex particles and diameter of the particle size are changed under the condition of the fixed incident beam (He-Ne Laser) . (2) For determining the soot particle size and concentration in flames, it is advisable to use the measured scattered light intensities [S2 (γ) /S1 (90°) ] at various angles which corresponds to the computed values of [I2 (γ) /I1 (90°) ] .
