Coal fired power plant boilers are a type of power plant that make use of the combustion of coal in order to generate electricity. Their use provides around 40% of the world's electricity and they are primarily used in developing countries. Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 70-75% of their electricity needs. More than half of the electricity generated in the world is by using coal as the primary fuel.

Why Choose Coal As Fuel For Power Plant

A. Coal Resource

Coal, the second source of primary energy (roughly 30%), is mostly used for power generation. Coal dominates the global energy arena due to its abundance, affordability and wide distribution across the world. Coal, when properly handled and combusted, is one of the cleanest fossil fuels available today.

B. Advantages

Security of supply

Competitiveness

Lower cost

Coal power plants provide stable and large-scale electricity generation. Of the Earth's fossil fuels, coal is the most abundant and widely dispersed, meaning that supplies are readily available.

Coal power has a competitive production cost. Fuel costs are low and coal markets are well-functioning.

compared to other sources of fuel, coal is stable, abundant, affordable, and easy to transport, store. Coal produces high energy when burned, hence cost is lower.

How Coal Power Plants Produce Electricity

The conversion from coal to electricity takes place in three stages.

stage1

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.

stage2

The heat from combustion of the coal boils water in the boiler to produce steam.

The steam is then piped to a turbine, the impulse and thrust created rotates the turbine.

The steam is then condensed and pumped back into the boiler to repeat the cycle.

stage3

In the third stage, rotation of the turbine rotates the generator rotor to produce electricity based of Faraday’s Principle of electromagnetic induction.
