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. U.S. coals, having a volatile ratio (also

Fire and Explosion Hazards in Cement ... - Dust Safety

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. This risk is present inside the pulverizing equipment and during transport ...

Prevention and mitigation of dust explosions in Paper

26/02/2014  A relatively thick accumulation of paper or pulp dust must be present to present a dust explosion risk in a room or building when compared to other combustible dusts such as coal, agricultural and food dust, metal dust and even wood2. For example, an accumulation of up to 1/3 in. for pulp and paper dusts compares to accumulations of 1/32 – 1/8 in. for most other combustible dusts.

Coal dust - Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
