Comparison and Analysis of Dust Explosion Characteristics Between Bungalow Granary and Silo Granary
In order to investigate the impact of different types of grain storage silos on grain dust explosions during transportation and storage. FLACS software was utilized to construct building models of flat and cylindrical grain silos. The study systematically compared the flame propagation range, maximum explosion overpressure, and temperature variations of different silo types by altering the dust concentration, ignition position, and silo shape. The simulation results indicate that dust concentration, ignition position, and silo shape all influence the explosion process. Flame release in flat grain silos occurs horizontally, whereas in cylindrical grain silos, it occurs from the top. Within the mass concentration range of 200–700 g/m3, an increase in dust concentration leads to higher maximum explosion overpressure and elevated temperatures at observation points. As the ignition source moves closer to the center of the dust cloud, the flame shape becomes more ellipsoidal, leading to higher maximum explosion overpressure and a shorter time to reach it.
