1 de dic. de 2020 · The ignition of flammable gas mixtures in underground spaces may cause sudden gas explosions, owing to the confined and congested conditions. These may result in disastrous consequences, including large numbers of casualties, huge economic losses, and negative impacts on society.
16 de ago. de 2022 · Once a gas explosion occurs, it can cause a large number of casualties, huge economic losses, and severe negative societal effects. According to yearly statistics from the Chinese National Coal Regulatory Administration, the vast majority of major accidents in Chinese coal mines are gas explosions.
1 de sept. de 2022 · In summary, when the concentration was 8% and C t 130, the consequences of natural gas explosion overpressure were most consistent with the actual damage at the accident site, with the natural gas explosion overpressure reaching more than 90 kPa, which was enough to cause serious injury to building structures and personnel.
1 de feb. de 2024 · Abstract. For gas leakage explosion accidents that occur in high blockage environments, the failure of building structures often leads to the evolution of explosion waves becoming unpredictable, resulting in the amplification of accident consequences.
9 de sept. de 2021 · In recent years, the explosion accidents of liquefied petroleum gas (LPG) have induced tremendous losses. To analyze the deflagration danger of LPG, the explosion pressure and flame propagation features of the premixed LPG–air mixture in a closed pipeline at increased initial pressures and temperatures were examined by the numerical method.
The explosion overpressure for stoichiometric propane-air mixts. in a room without obstacles is too low to cause serious injury. The explosion temp. for stoichiometric propane-air mixts. in a room without obstacles can reach up to 2200 K, which is one of major hazards in a gas explosion in a room.
14 de mar. de 2022 · Abstract. In the processes of chemical production, storage, transportation, and utilization, when a gas explosion occurs, the postexplosion environmental parameters (environmental pressure, environmental temperature, and environmental humidity) are significant prerequisites for inducing secondary explosions and other derivative disasters.
