A simplified design schematic of a so-called roll mill is presented in Fig. 2. Raw coal is transported on a conveyor belt and dropped into the mill, where it falls onto a grinding table and is crushed by rollers. Primary air, blown from the bottom of the mill, picks up fine coal particles and transports them into the classifier section.

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 fluid …
