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.

In the experiment for sintering oxygen-enriched ignition, increased oxygen enrichment will increase the theoretical sintering ignition temperature. In addition, the ignition fuel used in the laboratory sinter pot experiment is liquefied petroleum gas with a quite different calorific value and composition from those of blast furnace gas used by the sintering trolley.
According to the TG-DTA curves, the first strong exothermic peak of the DTA curves generally corresponds to a significant loss of weight in TG curve, which can be extrapolated by ignition temperature (Te).
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.
From Figure 2, the initial ignition temperature (180[degrees]C) was similar in case of RCG and it blends (RCG+S and RCG+P).
Higher values of the ignition temperature of volatile products and self-ignition and time for ignition or self-ignition confirm the above conclusion, since polyester materials containing flame retardants Mo[O.sub.3] and [Sb.sub.2][O.sub.3] inhibit the initiation of the combustion reaction, and thus inhibit fire development at its initial phase.
The thermal ignition temperature (T be0 or T TIT ) are obtained by substituting E eo and T e0 into Zhang et al.
If the compression of the air fuel mixture causes the gases to get hot enough to reach the ignition temperature of the fuel, it detonates.
Unlike gases and vapours, the ignition mechanism may be important for the prevention and mitigation of dust explosions: Minimum Ignition Energy (MIE), Minimum Ignition Temperature (MIT), and Auto Ignition Temperature (AIT) are essential.
Without a spark to occur, the auto ignition temperature of petrol is about 400 degrees Celsius."
The combustion of some oil shales is problematic due to higher ignition temperature, high ash content, and high emission rates of greenhouse gases.
An obvious and very important consideration when installing equipment in a hazardous location is the ignition temperature of the flammable material, i.e.
The lower ignition temperature also helps reduce the dreaded crud ring that forms where powder and sabot/bullet meet.
