Torrefaction. Prabir Basu, in Biomass Gasification, Pyrolysis and Torrefaction (Third Edition), 2018. Explosion Potential of Torrefied Dust. Dust explosion is a major problem in handling and conveying fine dusts especially of easily ignitable materials. Torrefaction makes biomass brittle and could result in more dust during handling. Additionally, due to its high reactivity and low ...
