In addition, the fineness of the coal directly reduces losses by decreasing the amount of unburned carbon in fly and bottom ash [3], [4]. Because coal pulverizing and separation are important for PCF PPs, to increase coal fineness with adequate classification, numerous studies have been conducted on pulverizing and separation systems.

The coal falls into a conveyor system which carries it out of the mine. The roof is supported by large steel supports, attached to the longwall machine. As the machine moves forward, the roof supports are advanced. The roof behind the supports is allowed to fall. Nearly 80 percent of the coal can be removed using this method.

Higher the VM, the coal will burn better and burn nearer to the burner. VM varies from about 12% to 24% in the coals used at our stations. • Low VM coal requires a better PF fineness compared to high VM coal. This aspect is to be kept in mind while loading the mill and fineness readings are to be taken and monitored more frequently.
