What does a high volatile coal mean?
The higher the volatile content, the lower the minimum ignition temperature of the coal dust, the easier it is to burn, and the faster the spreading of the explosion flame. 23,24. The lower the volatile content of coal, the lower the oxygen consumption rate and heat release intensity, and the less likely it is to burn.
