Explosion is a very rapid contained fire
WebExplosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion. The speed at which explosives decompose permits their classification as high or low explosives. WebApr 8, 2024 · When the fire is burning in a ventilation controlled regime, the increase in heat release rate may result from increased ventilation. Backdraft A backdraft involves deflagration (explosion) or rapid combustion of hot pyrolysis products and flammable products of combustion upon mixing with air.

WebApr 1, 2011 · Generally, an explosion is defined as a very rapid release of high-pressure gas into the environment. The energy from this very rapid release of the high-pressure gas is dissipated in the form of a shock wave. WebNov 1, 2010 · An explosion is a violent release of energy caused by a physical or chemical reaction. It is accompanied by a rapid increase in pressure and usually temperature. The high speed of reaction distinguishes the explosive reaction from an ordinary combustion. An explosion creates a shock wave.
WebThe fire soon raged out of control. At 9:12 a.m., the ammonium nitrate exploded, sending the 7200-ton ship 20 feet in the air—the first of a series of catastrophic events. Burning debris reached surrounding oil refineries and chemical plants. A 15-foot tidal wave caused two other ships anchored in the harbor to collide. Both were soon ablaze.
WebAn explosion is an expansion of material that travels faster than the speed of sound, resulting in a shockwave. Anything expansion that's slower than the speed of sound is … WebExplosive properties are associated with the presence of certain chemical groups in a molecule which can react to produce very rapid increases in temperature or pressure. The screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release.
