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. Table 23.7 shows some relevant data [5].

Acetone, propanone. Anthracite - glow point. Bituminous coal - glow point. Butyl methyl ketone. Carbon disulfide, CS 2. Carbon monoxide. Dichloromethane. Diesel, Jet A-1.

2015-7-29 · ignition temperature of a coal dust cloud approaches a limiting temperature as low as 440 EC (824 EF). The ignition temperature of a Pittsburgh Seam coal dust cloud is fairly constant as the particle size increases to about 180 microns. Further increases in size result in rapid rise in the ignition temperature requirements.
