· Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.

Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.
Explosibility of coal dust has been studied in laboratories, in explosion galleries and in an experimental coal mine. The data and results obtained from the tests showed that finely pulverized coal dust has a lower explosive limit of to ounces per cubic foot.
The explosion characteristics are shown in Table 1. The ignition energy of the coal powder is 50mJ, so electrostatic and mechanic sparks should be considered as ignition sources. The explosion index K max is less than 10 /s, so venting and suppression are effective for the coal powder. Table 1: Explosion characteristics of the coal powder
