摘　　要：对不同粒度煤粉的结构形态、内孔分布和燃烧特性进行了试验。结果表明,煤粉粒度越小,孔容积越大,燃烧温度越低,燃尽率越高。研究结果对确定再燃所需要的最佳煤粉细度具有一定参考意义。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.
