Coal Type: The subbituminous coals have explosion frequencies of about twice those of bituminous coals. The explosion values of lignite coals were ignored due to the extremely small population. Coal Volatility: Explosion frequency increases with an increase in volatility content, but this trend is as weak statistically as the others.

Dust Explosion Prevention A dust cloud of flammable concentration can be produced in industry either by design or by chance. For example, lean-phase pneumatic transfer systems handling flammable dust have an almost continual dust cloud present. In processes such as the filling and emptying of dust containers a dust cloud of flammable concentration is produced transiently.

Dust Explosion - an overview | ScienceDirect Topics
Torrefaction makes biomass brittle and could result in more dust during handling. Additionally, due to its high reactivity and low moisture content, torrefied biomass could more easily ignite than coal, which in turn increases the explosion potential of the torrefied biomass within mills or conveying pipes. Chapter 11 discusses this aspect further.
