Overall characterization of cork dust explosion

Experimental investigation and modelling of aluminum dusts explosions in the 20 L sphere

“…It induces less heat losses by convection or radiation towards the 20 L apparatus and an augmentation of the maximum explosion pressure (Pilão et al, 2006). This assessment is confirmed by the experimental data presented in Fig.…”

“…Results demonstrating that the activation energy of aluminum oxidation augments with the particle size were reported by Rai et al (2006). Moreover, as pointed out by Pilão, Ramalho, & Pinho (2006), P m increases as a function of the ignition energy. It follows that, in the case of small particles, only a limited amount of the energy delivered by the ignitors is probably devoted to the ignition phase and a significant one to heat propagation.…”

Experiment-based investigations of magnesium dust explosion characteristics

“…The stabilization of (dp/dt) max at concentrations higher than the worstcase was also identified for aluminum dust (Dufaud, Traore, Perrin, Chazelet, & Thomas, 2010). Nevertheless, no reappearance about the mentioned stabilization was identified for cork dust (Pilao, Ramalho, & Pinho, 2006), silicon dust (Matsuda, Yashima, Nifuku, & Enomoto, 2001) and graphite dust (Denkevits & Dorofeev, 2006). Consequently, the stabilization of (dp/dt) max as well as burning velocity within highly loaded dust clouds means that the evidence for Mg/N 2 reaction in the oxygen deficient atmosphere is somewhat found again.…”

Explosion characteristics of pulverised torrefied and raw Norway spruce (Picea abies) and Southern pine (Pinus palustris) in comparison to bituminous coal

“…Explosion characteristics of non fibrous biomass powders have been investigated by other researchers and by the Leeds group, where the residues found after explosion have been analysed (17)(18)(19)(20). Other studies on the explosibility of fibrous biomass are available (21), but these used the Hartmann tube method which was criticised due to poor dispersion of the dust and abandoned in favour of the current standard methods using the 1 m 3 and 20 L sphere vessels.…”
