Question

how coal generate elctricity​

Answer 1

Explanation:

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Answer 2

• Coal-fired power stations generate energy by steaming coal.
• The steam is forced into a turbine, which turns a generator to produce energy.
• After cooling, the steam is condensed back into water and returned to the boiler to repeat the process.

As an example, consider the following scenario:

• The Kingston Fossil Plant near Knoxville, Tennessee, utilizes coal to heat its boilers to roughly 1,000 degrees Fahrenheit in order to produce high-pressure steam.
• More than 1,800 pounds per square inch of steam is supplied to the turbines.
• The turbines are linked to the generators, which spin at 3,600 RPM to produce 20,000 volts of alternating current (AC).
• To cool and condense the steam generated by the turbines, river water is routed via tubes in a condenser.
