Effects of the Dimensionless Light Extinction Coefficient on Soot Particles Concentration for Different Coal Combustion Conditions

This study investigated the effect of dimensionless light extinction coefficient on soot particles concentration for different combustion conditions bituminous coal. The pressures and burning temperatures were set between 0.1 MPa 0.3 MPa, 550 ℃ to 650 ℃, respectively. was experimentally measured calculated using full-field method Abel deconvolution technique. results this showed that increased with increasing temperature under constant pressure. Further, when constant, also increased. In addition, as flame height increased, changed by about 15% a function at same height.
