The composition of smoke depends on the nature of the burning fuel and the conditions of combustion. Fires with high availability of oxygen burn at a high temperature and with a small amount of smoke produced; the particles are mostly composed of ash, or with large temperature differences, of condensed aerosol of water.

A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] At a certain point in the combustion reaction, called the ignition point, flames are produced.
Smoke with a suitable composition can be used as a fire suppression agent.A pyrotechnic composition similar to black powder, composed of 15% charcoal and 85% potassium nitrate, generates thick smoke composed of particles of mainly potassium carbonate, which has fire extinguishing properties.
For instance, at the climax of their song "Careful with That Axe, Eugene", a blast of smoke was set off at the back of the stage. Bands such as the Who, KISS and Queen soon followed with use of pyrotechnics in their shows. Michael Jackson attempted using pyrotechnics in a 1984 Pepsi advertisement, [2] where a stray spark caused a small fire in ...
But earlier in 2024, multiple states issued air quality warnings as smoke from “out of control” wildfires in Canada blew across the border for the second year in a row. The smoke makes people ...
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
If a fire occurs on the track, there is no flame or smoke to obstruct the view of fast-approaching drivers, but this can also delay visual detection of the fire and the initiation of fire suppression. A seven-car crash on the second lap of the 1964 Indianapolis 500 resulted in USAC's decision to encourage, and later mandate, the use of methanol.
