Abstract
The structural form, inner pore distribution, and burning behavior of pulverized coal with different particle size have been tested. Results show that the smaller the particle size of pulverized coal, the greater the porous volume, the lower the burning temperature, and the higher the burnaway rate. The results of study have certain reference significance for determining optimal coal fineness required for reburning.
