Most explosions in coal mill plants have their initial ignition location within the mill chamber. This is because the mill chamber is the section of the plant in which the conditions for the ignition of air dispersed fuel are most favourable, as well as the risk that tramp metal gets trapped in the grinding media.

The grinding area is considered as the most critical one at cement plants with regards to dust explosion hazards. The following cursory analysis explains how the five conditions for dust explosions are given in coal grinding plants 1 Combustible dust Coal 2 Dispersion Coal dust is dispersed into the pulveriser, classifier, bag filter, fine ...
A conventional vertical roller pulveriser is used for the grinding process. After the coal is ground in the pulveriser, the coal fines are blown upwards via a bag filter to be stored in the fine coal bins. The grinding area is considered as the most critical one at cement plants with regards to dust explosion
Feb 17, 2008 Coal Dust Explosion in Coal fired Cement plant Its prevention is necessary for safety and enhancement of environment standards. The numbers of coal fired industrial systems, particularly cement plants, is rapidly increasing, because of high cost and uncertainty in availability of fuel oil and natural gas.
Metal entering the coal mill with the coal can cause sparks or become hot enough to start a fire or explosion. EMERGENCY CONSIDERATIONS. On a coal grinding and firing system, maintenance work or inspections that require opening equipment should only be performed when given specific instructions and under the direct supervision of authorized ...
