This diagram illustrates the main steps involved in generating electricity from coal:
1. Coal Mining:
* Coal is extracted from the earth through mining operations.
* It is then transported to the power plant.
2. Coal Handling:
* Coal is delivered to the power plant and stored in a designated area.
* It is then conveyed to the boiler.
3. Combustion:
* Coal is burned in a boiler, releasing heat energy.
* This heat turns water into steam.
4. Steam Generation:
* The heat from burning coal boils water in a boiler, creating high-pressure steam.
5. Turbine Rotation:
* The high-pressure steam drives a turbine, causing it to rotate.
6. Generator Operation:
* The rotating turbine turns a generator, which produces electricity.
7. Electricity Transmission:
* The generated electricity is then transmitted through power lines to homes and businesses.
8. Waste Products:
* Burning coal produces waste products such as ash, sulfur dioxide, and nitrogen oxides.
* These pollutants need to be captured and treated before being released into the atmosphere.
