Generator uses the mechanical energy so generated by the turbines to generate electricity at considerably high voltage. 6. Condenser. Steam leaving the turbines is condensed in a condenser, to be pumped back to the boiler. Cold water from a water source (river) or expansion process is used to cool down the steam into water.

A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

A coalfired power station burns coal to generate electricity. There are many such power plants around the world, including in Israel. Their operating principle is simple: Burning coal heats water in a closed system. The water evaporates and becomes steam. The steam is used to drive a turbine, driving the magnet array that creates an electric field. In fact, this is the transformation of the ...
