چکیده انگلیسی
This work uses the ISO 1Â m3 dust explosion equipment to study the explosion properties and combustion characteristics of pulverized biomass dust clouds. An unreported feature of this apparatus is that in rich concentrations only about half the dust injected is burned in the explosion, while the overpressures remain high. This work was undertaken to try to understand the mechanisms of these phenomena, through the accounting of the debris at the end of the explosion, some of which was found in the form of impacted “cake” against the vessel wall. One possible explanation is that the residue material was biomass dust blown ahead of the flame by the explosion induced wind, impacted on the walls where then the flame side underwent flame impingement pyrolysis and the metal (wall) side material was compacted but largely chemically unchanged. The results also show that the heat transfer insulation provided by the powder wall layer contributes to the higher observed pressures. The risk of explosion with significant overpressures remains at 100% in very rich environments (equivalence ratios of up to 6) although these environments are leaner than thought due to material sequestration within the “cake”. There was little indication that a rich combustion limit was approached, this was determined in standard testing equipment that has been modified and calibrated to handle larger quantities of powder than normal.
