Pulverised Coal - an overview ScienceDirect Topics

A coal-fired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
