Abstract

In this study, a 20-L spherical explosion vessel, hot plate apparatus, Godbert-Greenwald furnace apparatus, and TG-FTIR were used to investigate the explosion and combustion characteristics of three biomass dusts: dalbergia cochinchinensis (DC), pine sawdust (PS), and cupressus funebris (CF). DC with lower minimum explosible concentration (70-80 g/m³), larger maximum explosion pressure (0.742 MPa) and larger maximum explosion pressure rise rate (80.14 MPa/s) had the greatest explosion hazard in three biomass dusts. The apparent activation energy of DC and CF were lower than that of PS, and the main gas products of three samples included CO₂, CO, CH₃COOH, and H₂O. The volatile matter content of DC characterized by the weight loss and the number of gas products of combustion process was higher than those of PS and CF, showing that the volatile matter content of biomass dust was one of the main factors affecting combustion and explosion hazard.
