A modified Hartmann tube apparatus was used to study the explosivity properties of dusts from torrefied biomass pellets. The sensitivity of the dusts to explode was assessed by determining the minimum ignition energies (MIE) and the minimum explosible concentrations (MEC). The severity of the explosion was evaluated by flame front velocity (FFV) measurements via a method developed by ... https://www.mamapaisa.com/product-category/firm-hold-hairspray/
