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.

Process description of a coal-fired power plant In a coal-fired power coal is burnt to produce electricity. In a coal-fired plant, pulverisers are used to mill the coal
Today, coal is the principal fuel for electricity generation worldwide. Coal-fired power generation provides over 40% of world electricity (Fig. 11.1).In China, coal's share is about 70% while in the USA, it is more than 43%. Coal is the dominant fuel source for power generation because, unlike oil, it is distributed widely and in large quantities …
Before feeding, the coal is given to a pulverize mill for crushing raw coal into small particles. This is because direct raw coal cannot be given inside for burning. It requires coal in powdered form. ... Coal-Based Thermal Power Plants; Gas Turbine Power Plants; Oil Fired Thermal Power Plants; Combined Cycle Power Plants;
