Chapter 1 Steam Power Plant Cycles. Pages 1 37. Thermodynamics deals with the conversion of one form of energy to another. In a thermodynamic cycle a fluid is returned to its initial state after transfer of heat/work across the system boundary. Laws of thermodynamics form the basis on which the whole foundation of thermodynamics is developed.

A coalfired 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. After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to ...

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Brown and black coal are mostly used as a source of fuel for power stations. Burning the coal produces heat which is used to make steam, so the the coal is sometimes called thermal or steam coal. The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements.
