  2. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  3. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    GPSA currently uses 60 °F), minus the enthalpy of the stoichiometric oxygen (O 2) at the reference temperature, minus the heat of vaporization of the vapor content of the combustion products. The definition in which the combustion products are all returned to the reference temperature is more easily calculated from the higher heating value ...

  4. Spontaneous combustion - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_combustion

    A large compost pile can spontaneously combust if improperly managed. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. [1]

  5. Fire - Wikipedia

    en.wikipedia.org/wiki/Fire

    Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point. Flames consist primarily of carbon dioxide, water vapor, oxygen, and ...

  6. Smouldering - Wikipedia

    en.wikipedia.org/wiki/Smouldering

    Smouldering combustion in glowing embers of barbecue coal briquettes. Smouldering (British English) or smoldering (American English; see spelling differences) is the slow, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel. [1]

  7. Flash point - Wikipedia

    en.wikipedia.org/wiki/Flash_point

    A certain concentration of a flammable or combustible vapor is necessary to sustain combustion in air, the lower flammable limit, and that concentration is specific to each flammable or combustible liquid. The flash point is the lowest temperature at which there will be enough flammable vapor to support combustion when an ignition source is ...

  8. Flame speed - Wikipedia

    en.wikipedia.org/wiki/Flame_speed

    The flame speed is the measured rate of expansion of the flame front in a combustion reaction. Whereas flame velocity is generally used for a fuel, a related term is explosive velocity, which is the same relationship measured for an explosive. Combustion engineers differentiate between the laminar flame speed and turbulent flame speed.

  9. Burn rate (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Burn_rate_(chemistry)

    Burn rate (typically expressed in mm/s or in/s) is the sample length over time at a given pressure and temperature. For solid fuel propellant, the most common method of measuring burn rate is the Crawford Type Strand Burning Rate Bomb System [ 3 ] (also known as the Crawford Burner or Strand Burner), as described in MIL-STD-286C.
