Step by step on how electricity is generated using coal?

Answer 1

Here are the steps involved in generating electricity using coal:

Mining: Coal is extracted from underground or open-pit mines. The mining process involves drilling, blasting, and removing layers of soil or rock to access the coal seams.

Transport: Once mined, the coal is transported to a power plant via trucks, trains, barges, or conveyors. This transportation is necessary to move the coal from the mine to the power plant where it will be used to generate electricity.

Preparation: At the power plant, the coal is crushed into a fine powder and then pulverized to increase its surface area. This process helps improve the efficiency of combustion.

Combustion: The pulverized coal is mixed with air and burned in a boiler to release heat energy. This combustion process generates high-pressure steam.

Steam turbine: The high-pressure steam produced from the combustion of coal is directed towards a steam turbine. As the steam flows over the turbine's blades, it causes them to rotate.

Generator: The rotating turbine is connected to a generator, which consists of a magnetic field and copper coils, through a shaft. As the turbine spins, the magnetic field induces an electric current in the copper coils, generating electricity.

Cooling: After passing through the turbine, the spent steam is cooled and condensed back into water in a condenser. This condensed water is then returned to the boiler for reuse.

Transmission: The electricity generated is stepped up to a high voltage using Transformers. This high-voltage electricity is more efficient for long-distance transmission and is sent through power lines to homes, businesses, and other electrical loads.

Distribution: At the local level, transformers step down the voltage to a safe level for distribution. The electricity is then distributed through a network of power lines and substations, reaching individual customers.

Consumption: Finally, electricity reaches the end-users who utilize it for various purposes, such as powering appliances, lighting, or running machinery.

It's worth noting that coal-fired power plants are being phased out in many countries due to environmental concerns associated with greenhouse gas emissions and air pollution. However, this step-by-step process remains applicable to traditional coal-fired power generation.

Answer 2

# Burn the coal to # Heat water to steam. # Use the steam to

# Turn a dynamo which # Produces electricity. All fossil fuels (wood, coal, oil and natural gas) use this system.
