Electricity from coal is the electric power made from the energy stored in coal. Carbon, made from ancient plant material, gives coal most of its energy. This energy is released when coal is burned.

We use coal-generated electricity for
heating,
cooling,
cooking,
lighting,
transportation,
communication,
farming,
industry,
healthcare,
and much more!

Releasing Coal's Energy
The process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity:

A machine called a pulverizer grinds the coal into a fine powder.

The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace.
The burning coal heats water in a boiler, creating steam.
Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine.
The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy. This happens when magnets inside a copper coil in the generator spin.
A condenser cools the steam moving through the turbine. As the steam is condensed, it turns back into water.
The water returns to the boiler, and the cycle begins again
Other new processes of using coal to make electricity include the following:
Fluidized bed combustion (FBC), in which coal is inserted into a bed of particles suspended in air that react with the coal to heat the boiler and make steam
Combined-cycle systems, in which (1) gas produced by heating coal operates a combustion turbine connected to a generator and (2) the exhaust gases from this turbine heat water, which in turn operates a steam-powered generator.

Hello

The best process for extract electricity from coal is a NUCLEAR reaction gived for the following steps

When you discharge a big condenser in a coal rod you get the following nuclear reaction

C + e = B

C is carbon , e the electron from your condenser and B a borum inestable isotope


Borum then in its inestability retransform to carbon

B = C + e

returning that electron but at too more energy in the way of beta radiation, that radiation is able to get in a toroid and then high power and electricity

You have for this method direct electricity from the coal without an intermediate process like water heaters, turbines, etc, is the best method

Coal is burned to produce warmth, which in turn turns water into steam, which drives a trubine, which generates the electrical energy by ability of shifting magnets interior a coil of cord. ...So, the coal is used to warmth water.

Its called a power plant, and we have them all over the USA. So do a search on coal fired power plant.
