The increase in the fluctuation intensity of gas temperature will further enhance the instantaneous particle mass loss during the coaldevolatilization processes.
随着气相温度脉动强度的增加，这种加快颗粒瞬时质量下降即挥发分释放的趋势更为明显。

During the devolatilization, the hollow structure of coal particles is formed due to the rapid release of volatile, which can result in more rapid combustion of char particles.
热解时挥发份的迅速释放及煤的热塑性导致了颗粒内部的空心结构，这种结构有效地提高炭粒的燃烧速率。

The effects of gas temperature fluctuation on the devolatilization of pulverized coal particles with different diameters are explored under different time-averaged gas temperature.
