In this type of crushing first coal is break due to impact and further scrub between two hard surfaces to get desired coal size. Some crushers are work only on principle of impact crushing. Generally these crushers are used before final crushers.
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.
Principles of Heat Transfer. Heat is transferred to and from objects -- such as you and your home -- via three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows.
