Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

The occurrence and size distribution of pyrite are determined by the depositional environment of coal. The particle size of pyrite in different occurrence modes varies greatly, ranging from centimeters to submicrons. Coarse-particle pyrite is mainly enriched in agglomerated, nodular, and fracture-filling forms, and fine-grained pyrite has …

2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.
