10.09.2015· Coal Mill Operation. Fires or explosions most likely occur during startup and shutdown of a coal mill system. If a small amount of coal remains in the mill after it is shut down, it slowly increases in temperature. If the pulverized coal undergoes spontaneous heating and the coal mill is restarted with hot embers present, an explosion or fire is possible. Although this does not happen often

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed.
The Milling System 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. Here the risk exists that tramp metal can get trapped in the grinding media. Grinding causes impact and friction. Many fuel mills in
