Coal is burned to create steam, which is then used to generate electricity at coal-fired power stations. At extreme pressure, the steam generated enters a turbine, which turns a generator to provide power. In order to restart the process, the steam is then cooled, condensed back into water, and fed back into the boiler.
Why do we need coal to generate Electricity:
In the US, coal is largely utilized as a fuel to produce electricity. Bituminous coal, subbituminous coal, or lignite are all burnt in coal-fired power plants. Heat from the coal’s burning is utilized to turn water into high-pressure steam, which powers a turbine and generates electricity.
How a coal plant works for generation of Electricity:
Fundamentally, the process by which coal produces electricity today is the same as it was in Edison’s time and is comparable to that of other thermal power plants that use gas: the coal is burned, heating water to make steam, which spins a turbine to generate electricity. This was the primary method through which Britain generated most of its power in the late nineteenth and early twentieth century. Before the “rush for petrol” signalled its decline, coal generation reached its peak in the early 1990s, accounting for more than 60% of the mix.
How is the production of coal used for generating electricity:
In a combustion chamber, coal is burned to create heat, which then causes water to boil. Steam begins to emerge from the water, spinning the propellers. To generate energy, a generator is connected to the turbines.
