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 .
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.
Cases also exist where the ignition factor is not the activation energy. For example, a smoke explosion is a very violent combustion of unburned gases contained in the smoke created by a sudden fresh air input (oxidizer input). The interval in which an air/gas mix can burn is limited by the explosive limits of the air.
The massive explosion at the Sandman Signature Hotel in downtown Fort Worth, suspected as a gas leak, may be part of a worsening trend across the US. Gas leak explosions are happening more often ...
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 ...
Lighting a fart. 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".
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.
The Food and Drug Administration (FDA) regulates nitrous oxide under its Food Drug and Cosmetics Act. Although buying nitrous oxide for its intended purpose is legal, some states have outlawed the ...
