Minimum Ignition Temperature test Testing for MIT
Minimum ignition temperature (MIT) Minimum ignition temperature of a dust cloud The minimum ignition temperature (MIT) is the lowest temperature of a hot surface that will cause a dust cloud, rather than a dust layer, to ignite and propagate flame. The test follows BS EN 5028121:1999 (Methods of determining minimum ignition temperatures).

HOT SURFACE IGNITION TEMPERATURE OF DUST LAYERS
seam coal, 360oC for paper dust, 270℃ for Arabic gum powder, and > 400oC for brass powder. The addition of 510 weight percent stearic acid powder resulted in significantly lower ignition temperature of brass powder. When combustible liquids were added to the dust layer, the ignition temperatures did not decrease regardless

Ignition Temperature an overview ScienceDirect Topics
Ignition temperature of coal and other dust is not affected by particle size. A big difference is made by the way coal dust comes in contact with a heat source. Thus, layered powder of coal can ignite at a much lower temperature (160°C approx.), whereas a cloud of coal dust will need 450–650°C to ignite.

Dust explosion Wikipedia
In the coal mining industry, a methane explosion can initiate a coal dust explosion, which can then engulf an entire mine pit. As a precaution, incombustible stone dust may be spread along mine roadways, or stored in trays hanging from the roof, to dilute the coal dust stirred up by a shockwave to the point where it cannot burn. Mines may also
