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.

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
