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 · Gas explosions are undoubtedly the most serious type of accidents [ 1, 2, 3 ]. Once a gas explosion occurs, it can cause a large number of casualties, huge economic losses, and severe negative societal effects.
1 de sept. de 2022 · In summary, when the concentration was 8% and Ct 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 · Based on the numerical analysis results, the explosion of 4.0–4.1 m 3 combustible gas is sufficient to destroy a large number of walls with a maximum indoor overpressure of 1.130 bar and create a high-pressure injury area of 10 m and a high-temperature injury area of 14 m outdoors.
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
13 de jul. de 2022 · To determine the law of indoor natural gas leakage and explosion hazards, based on experiment and simulation, the nature of natural gas explosion, the distribution law of natural gas volume fraction, flame propagation, temperature, and shock wave overpressure were studied.
14 de mar. de 2022 · (7) Therefore, in the processes of chemical production, storage, transportation, and utilization, when a gas leak occurs, it is extremely easy to cause gas explosions, and even induce more severe secondary explosions and multiple explosion accidents, which would result in huge economic and property losses, and personal casualties. (8−11 ...
