  • Coal Dust Explosions in the Cement Industry

     · Select laboratory testing is routinely carried out to investigate cement plant explosions involving pulverized coal dust. Samples of dust taken from the pulverizer are screened and a particle size distribution profile is obtained. A proximate analysis test provides information on volatile matter and fixed carbon content of the particular coal sample.

    Explosions in coal mines were common during this period but again it was assumed that flammable gas was the cause no thought being given to the possible effects of airborne coal dust. It was not until the latter part of the nineteenth century that it was realised that coal dust could ignite and explode in the absense of gas or that flour dust alone was responsible for the increasing number of explosions in mills.
