  • Fire and Explosion Hazards in Cement Manufacturing

    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.

  • Preventing Coal Dust Explosions in Underground Coal Mines

    • Heat transfer to the coal dust particles results in an exothermic reaction and expansion of the air in the entry. • As the explosion progresses the pressure wave continues to disperse entry dust adding fuel to the explosion. • Finer coal dust is more explosible and requires more rock dust to inert.
