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.

Fire and Explosion Prevention in Coal ... - Babcock Power
There is experimental evidence that coal dust/air mixtures do have a lower explosive limit (i.e., that concen- tration of coal in air below which an explosion does not occur), but do not have an upper explosive limit as long as the coal/ air mixture can be considered a cloud. In practice, a fire occurring during normal pulverizer
