Coal and Ash Handling Arrangement: The coal and ash handling plant generally consists of: (i) Coal storage, (ii) Coal handling plant, (iii) Ash handling plant, and (iv) Ash storage. The coal is stored in a coal storage plant from where it is delivered to the coal handling plant. In coal handling it is crushed into small pieces for proper burning.

A coal-fired power plant (Fig. 2) operates by burning coal to generate heat, which is then used to produce steam in a boiler.The high-pressure steam drives turbines connected to generators, converting the kinetic energy into electricity. Coal-fired power plants have long been prominent in electricity generation due to the abundant availability of coal reserves.

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
