Abstract The radiative characteristics of char and ash in the pulverized coal furnace at the wavelength of 560 nm are analyzed here. The particles’ radiative coefficients are calculated in the exit of the burner and in the upper part of the furnace separately according to the Mie theory. It can be inferred that in the exit of the burner, char has a great effect on the particles’ radiative coefficient, which accounts for a percentage of 90%. While in the upper of the furnace, ash dominates the particles’ radiative coefficient. The scattering ratio of the ash is calculated to be 91.6 and the scattering ratio of the char is only 50%.
