Coal is a fossil fuel and has been generating electricity in Great Britain since the industrial revolution. But the decarbonisation of the grid will see it phased out by the end of 2024. In 1882, Thomas Edison's Holborn Viaduct coal plant started generating electricity for public use. It was the first power station of its kind, burning enough coal to provide energy to light 1,000 lamps in ...
The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal. Transporting coal Coal can be transported from mines and processing plants to consumers in several different ways:
Most and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.

Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climatedamaging carbon dioxide. This book explores how efficiency is measured and reported at coalfired power plants.
However, existing subcritical coal thermal power plants operate on efficiencies of about 33%. It is appropriate to install highefficiency thermal plants with resultant benefits of low emissions. ...
