The coal fired power plant boiler is the most important component of most coal-fired power plants. Virtually every power plant now operating or proposed incorporates a steam turbine in the electricity generating process. The boiler heats water until it becomes steam.

For sixty years coal fired boilers have been our main source of energy. More than half of world's electricity generation today is from coal fired power plants. From the small low pressure boilers in our houses to the high pressure large ultra supercritical thermal power plants, there are many types of boilers. Technology has changed from stoker fired to circulating fluidized bed boilers.

How Coal Power Plants Produce Electricity

The conversion from coal to electricity takes place in three stages.
Stage 1
The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat.
Stage 2
The second stage is the thermodynamic process.
1.The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and temperature.

2.The steam is then piped to a turbine.

3.The high pressure steam impinges and expands across a number of sets of blades in the turbine.

4.The impulse and the thrust created rotates the turbine.

5.The steam is then condensed and pumped back into the boiler to repeat the cycle.
Stage 3
In the third stage, rotation of the turbine rotates the generator rotor to produce electricity based of Faraday’s Principle of electromagnetic induction.
