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].
