Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. upon loss of feed to a pulverizer, the coal air.
Fire and explosion hazards in bag filters can arise due to any of the following factors spontaneous combustion, dust explosion, static electricity, and high temperature materials passing through the filters. bag filters used for the coal mill rank as one of the highest fire and explosion hazards in cement plants, due to the small particle size.
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.
If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the inrushing combustion air. even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill puffs. explosions in a pulverized coal system are normally called puffs. a mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
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. also, grinding causes impact and friction.

Pulverized coal injection (pci) is a wellestablished technology for hot metal (hm) production in a blast furnace (bf). it is practiced in most of the bfs and all the new bfs are normally built with pci capability. the composition and properties of the coal used for injection can influence the operation, stability and productivity of the bf.
Power generation typically involves direct firing systems. there is an air swept mill with direct pneumatic conveying through to the burners. the risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shockresistant. nfpa requires coal mills to be good for 50 psi.
Production normally takes place in a coke battery located near an integrated steel mill. in the battery, coke ovens are stacked in rows. coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1,100 degrees celsius (2,000 degrees fahrenheit). without oxygen, the coal does not burn it begins to melt.
