Fire safety engineering

How much power a fire puts out

In fire safety engineering, the heat release rate is the rate at which a burning item or compartment liberates energy, effectively the power output of the fire, usually expressed in kilowatts or megawatts. Babrauskas and Peacock's 1992 Heat release rate: The single most important variable in fire hazard argued that this quantity, more than ignitability or flame spread alone, governs how fast a fire grows, how much smoke and toxic gas it produces, and when a room reaches flashover, and that it can be measured directly by oxygen-consumption calorimetry. The referent is the time-resolved power of a fire, the master variable from which much of fire hazard and the design of fire models and tests follows.[1]

Unit
The energy released by a fire per unit time (kW or MW)
Recovery means
Not applicable
Measured by
Measured by oxygen-consumption calorimetry in cone calorimeters and room/furniture calorimeters, reported as a heat-release-rate curve and its peak
