ignition temperature

[ig′nish·ən ‚tem·prə·chər]
(chemistry)
The lowest temperature at which combustion begins and continues in a substance when it is heated in air. Also known as autogenous ignition temperature; ignition point.
(plasma physics)
The lowest temperature at which the fusion energy generated in a plasma exceeds the energy lost through bremsstrahlung radiation.

ignition temperature

Of a material, the minimum temperature required to initiate combustion.

The minimum auto ignition temperature of the diluted oil is determined by the most volatile species in the diluted oil--the heavy species of gasoline in the oil, the auto ignition temperatures of which are close to those of diesel fuel.
High ignition temperature indicates higher heat capacity of a biomass [13].
The obtained results of ignition temperature and self-ignition indicate that the impact of both additives on the flammability of the volatile phase, formed as a result of the thermal decomposition of PES, is insignificant taking into account the initiation of combustion that uses the Mo[O.
By decreasing the radius of particles, the ratio of the surface to the volume of heat transfer increases, which is led to enhancement of heat transfer rate to particles; therefore, the particles vaporize and reach to the ignition temperature sooner; finally, burning velocity and flame temperature increase with decreasing the particles radius.
The thermal ignition temperature (T be0 or T TIT ) are obtained by substituting E eo and T e0 into Zhang et al.
The higher octane is required solely to increase the ignition temperature of the fuel to avoid knocking.

Whereas machinery incorporating a flameproof enclosure may exhibit interior temperatures above the ignition temperature for the particular gas, the principle behind the "increased safety" concept aims at avoiding unacceptably high temperatures at all points inside and on the motor.
Gases and vapours are sub-divided into temperature classes depending on their ignition temperature, with increasing specifications from T1 to T6:
Therefore, determination and comparison of the substantial initiation parameters (ignition and flash ignition temperature, ignition and flash ignition induction period and critical heat flux) enables us to make a relative comparison of materials or products from the point of fire dynamics.
Flammable materials are grouped according to the ignition energy (gas groups) and classified for their minimum ignition temperature (temperature class).
