Spontaneous combustion of coal stockpiles can occur when the environment temperature exceeds the critical self-ignition temperature (CSIT), which strongly depends on the pile volume. As the name implies (autogenous), at this temperature, ignition source is not required to ignite; it is an auto process. ignition temperature translation in English - French Reverso dictionary, see also 'ignition key',ignition key',ignite',imagination', examples, definition, conjugation Definition of MIT What is the MIT of a dust ? 3.

However, it does not clarify whether it is on its own or due to an external source. Point d'inflammation: température où la quantité de vapeurs émises par le solvant est suffisante pour que la combustion continue même si l'on retire la source de chaleur à l'origine de l'inflammation. The key difference between flash point and auto ignition temperature is that flash point determines the lowest temperature at which vapour of a material starts ignition in the presence of an ignition source whereas auto ignition temperature is the lowest temperature at which a material can start ignition spontaneously.. Ignition Temperature Petrol 247–280 °C (477–536 °F) Diesel 210 °C (410 °F) Phosphorus,white 34 °C (93 °F) Ethanol 365 °C (689 °F) Iron 1,315 °C (2,399 °F) Paper 218–246 °C (424–475 °F) Lead 850 °C (1,560 °F) Leather 200–212 °C (392–414 °F) Hydrogen Abbreviation: T See more. They even say that ignition is a subjective term, so they are careful to define it clearly. The weight loss curve is used to define the ignition temperature. autoignition temperature \ Prononciation ? It is also used to characterize the fire hazards of fuels. La valeur proposée dans la définition de la température d'auto-inflammation; et. It is a comparative measure of how hot or cold a material is. Definition from Wiktionary, the free dictionary. Some also mentioned a flash point. The autoignition temperature of a substance is the temperature at or above which a material will spontaneously ignite (catch fire) without an external spark or flame.. Additional Info. Table 16.7 lists the auto-ignition temperatures for several energetic compounds (Huang and Wu 1994). To understand the difference between ignition temperature and fire point, we must first understand the definition of the two (2) parameters. autoignition temperature: The minimum temperature needed for self-sustained combustion in absence of a spark or flame, at which the vapours from a volatile liquid will ignite spontaneously. When a powder deposit covers a source of heat, it can lead to self ignition of the dust layer which starts to smoulder. The coldest theoretical temperature is called absolute zero.It is the temperature where the thermal motion of particles is at its minimum (not the same as motionless). As a result, the ignition temperature is of course higher than the flash point. 3rd Meeting WG on safety aspects of the use of R1234yf on MAC systems - Ispra, 24 January 2014.
