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 .
This can happen in rooms where the fire subsided because of lack of oxygen. The ignition source can be a smouldering object, or the stirring up of embers by the air track. Such an event is known as backdraft. A delayed flashover occurs when the colder gray smoke cloud ignites after congregating outside of its room of origin.
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb.. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases.
The main mechanism of detonation propagation is of a powerful pressure wave that compresses the unburnt gas ahead of the wave to a temperature above the autoignition temperature. In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction ...
Fart lighting, also known as pyroflatulence or flatus ignition, is the practice of igniting the gases produced by flatulence. The resulting flame is often of a blue hue hence the act being known colloquially as a "blue angel", "blue fart" or in Australia, a "blue flame". The fact that flatus is flammable and the actual combustion of it through ...
One year on from explosions that damaged the Nord Stream gas pipelines under the Baltic sea between Russia and Germany, the question of who was behind them is unresolved. On Sept. 26, 2022 ...
The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
When the fire involves burning metals like lithium, magnesium, titanium, [6] etc. (known as a class-D fire), it becomes even more important to consider the energy release. Because the metals react faster with water than with oxygen and thereby more energy is released, putting water on such a fire results in the fire getting hotter or even ...
