Coal fired power plant Energy Education

The turbine shaft is connected to the shaft of the generator, where magnets spin within wire coils to produce electricity. 4. Steam turns back into water After doing its work in the turbine, the steam is drawn into a large chamber in the basement of the power plant.

TVA How a Coal Plant Works

Coalfired 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.

Mapped: The world’s coal power plants in 2019

The map shows coal capacity, whereas electricity generation and CO2 emissions depend on a range of other factors. Most important is how often coal plants run – their load factor. Global average loads started falling in 2007 and coal power CO2 has levelled off since 2014. More on this below.
