Power Plant Engineering and Sources of Energy Basic

Prime mover is a primary source of power. All the machinery that provides power for performing various kinds of mechanical work is prime movers. It is a group of machines that transform various forms of energy such as thermal, electrical or pressure into mechanical energy. Engines, turbines, pumps and actuators are the examples of prime movers. On the basis of direction of movement, prime movers may be classiﬁed as reciprocating prime movers and rotating prime movers.

Power plant engineering is a branch of engineering which deals with conversion of various forms of energy into electrical energy. In thermal power plant, coal, diesel, petrol, natural gas, and kerosene oil are used as fuel and chemical energy of these fuels is converted into mechanical energy and then mechanical energy into electrical energy. In hydroelectric power plant, the potential energy of water is converted into mechanical energy as shaft power and then mechanical energy into electrical energy. In the case of nuclear energy, nuclear power is used to generate the heat required to produce superheated steam and then the heat energy is converted into mechanical energy and the mechanical energy is converted into electrical energy.
