Deflagration is a rapid combustion process that propagates through a material at subsonic speeds. This is in contrast to detonation, which is a combustion process that propagates at supersonic speeds. Deflagration typically occurs in gases, liquids, and solids, and is characterized by the release of heat and light. The propagation of deflagration is driven by the transfer of heat from the burning region to the unburned material, which preheats and ignites it.

The speed of deflagration depends on several factors, including the chemical properties of the combustible material, the pressure and temperature of the environment, and the geometry of the confinement. In open spaces, deflagration speeds are generally low, but they can increase significantly in confined spaces due to pressure buildup. This can lead to deflagration waves that can cause substantial damage.

Common examples of deflagration include the burning of natural gas in a stove, the explosion of gunpowder, and the rapid combustion of dusts in industrial settings. In many industrial processes, measures are taken to prevent or mitigate the effects of deflagration. This can include using inert atmospheres, explosion venting, or suppression systems. Understanding the principles of deflagration is crucial for safety in various fields, from aerospace to mining.
