Jun 07, 2018· It is important to remember that a mill fire, whether it be flaming, smoking or smoldering coal inside the mill means a mill explosion could be occur at any time. Any burning or smoldering material inside the mill can evolve into an explosion because they provide an ignition source if the air to fuel (coal) ratio is elevated or higher than desired.
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.
