Influence of air supply velocity on temperature field in the self heating process of coal [PDF]

open access: yes, 2017
The air supply velocity is an important factor affecting the spontaneous combustion of coal. The appropriate air velocity can not only provide the oxygen required for the oxidation reaction, but maintains the good heat storage environment.
