The analysis of individual mill design and operation is complex so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Figure 13.2 illustrates the typical key components of a VSM.
Thermal Power Plant Explanation. Thermal Power Plants also called Thermal Power Generation Plant or Thermal Power Station. A thermal power Plant Station is used to convert heat energy to electric power Energy for household and commercial applications.In the process of electric power generation, steam-operated turbines convert heat in to mechanical power and then finally electric power.
