Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.

A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy of …

The analysis of individual mill design 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. Fig. 16.2 illustrates the typical key components of a VSM.
