What is the difference between deflagration and conflagration?
is that conflagration is a large fire extending to many objects, or over a large space; a general burning while deflagration is the act of deflagrating; an intense fire; a conflagration or explosion specifically, combustion that spreads subsonically via thermal conduction.
What is the difference between deflagration and combustion?
Deflagrations and detonations A deflagration occurs when a flame front propagates by transferring heat and mass to the unburned air–vapor mixture ahead of the front. The combustion wave travels at subsonic speeds to unburned gas immediately ahead of the flame front.
What is the key difference between a detonation and a deflagration?
Detonation will produce a true shock wave as the result of the explosion, while deflagration will not. The important difference between these two is that some chemicals that deflagrate burn slow enough that they need confinement in order to be explosive.
What is a deflagration explosive?
Definition. A rapid chemical reaction in which the output of heat is sufficient to enable the reaction to proceed and accelerate without input of heat from another source.
What is a deflagration panel?
Deflagration protection systems vent the combustion gases and pressures from withing a building or structure so that structural or mechanical damage is minimised after a deflagration event.
What is chemical deflagration?
deflagration in Chemical Engineering Deflagration is an explosion in which the speed of burning is lower than the speed of sound in the surroundings. A detonation generates greater pressures and is more destructive than a deflagration.
What is the correct meaning of detonated?
to explode with sudden violence
Definition of detonate intransitive verb. : to explode with sudden violence. transitive verb. 1 : to cause to detonate detonate a bomb — compare deflagrate. 2 : to set off in a burst of activity : spark programs that detonated controversies.
How does deflagration detonation work?
Deflagration-to-detonation transition is the general process by which a subsonic combustion wave (deflagration or flame) becomes a supersonic combustion wave (detonation).
What is the difference between deflagration and detonation quizlet?
What is the difference between deflagration and detonation? Deflagration is characterized by very rapid oxidation that produces heat, light, and a subsonic pressure wave. Detonation is characterized by extremely rapid oxidation that produces a supersonic shockwave.
What is detonated bomb?
: to explode with sudden violence. transitive verb. 1 : to cause to detonate detonate a bomb — compare deflagrate. 2 : to set off in a burst of activity : spark programs that detonated controversies.

Is deflagration a type of combustion?
There are two types of “combustion explosions,” i.e. deflagrations and detonations. Deflagration propagates with velocity below the speed of sound in the mixture.
What is the difference between conflagration and deflagration?
is that conflagration is a large fire extending to many objects, or over a large space; a general burning while deflagration is the act of deflagrating; an intense fire; a conflagration or explosion specifically, combustion that spreads subsonically via thermal conduction.
What is deflagration venting?
The reduction of pressure generated in a vessel by a deflagration by allowing the emergency flow of the vessel contents from the vessel by means of an opening in the vessel, thus avoiding the failure of the vessel by overpressure.

What is meant by ventilation?
The reduction of pressure generated in a vessel by a deflagration by allowing the emergency flow of the vessel contents from the vessel by means of an opening in the vessel, thus avoiding the failure of the vessel by overpressure. The vent opening is usually closed by a pressure-relieving cover (e.g., rupture disk, explosion disk or hatch).
What does NFPA 68-2018 say about deflagration vents?
In general, NFPA 68-2018 details a heap of considerations in relation to deflagration vents, including their design, location, installation, maintenance, and use, so that they can vent combustion gases and pressures resulting from a deflagration within an enclosure to minimize damage. It also details performance calculations.
