Power Stations in South Africa Presentation.pptx

Presentation of different power stations in South Africa, both non-renewable and renewable power sources.

1. Power Stations in South Africa COAL POWER STATIONS & Alternatives By: Nicholas Mabila © Student energy, Coal.

2. Power Stations Electricity is produced in Power stations located in different parts of South Africa. In South Africa we have Coal, Solar, nuclear and hydropower stations. (Mofokeng, 2018)

3. What is a Power Station? Power station is a system used to generate electricity from a non-renewable and renewable fuel source . © Eskom, Coal power station ( Mofokeng, 2018)

4. Coal Power Station A coal-fired power station, also known as a coal power plant , is a facility that generates electricity by burning coal. These plants are a significant source of energy worldwide including South Africa, contributing to almost one-third of global electricity production. More than ninety million of tones of coal are burnt every year to produce electricity. (Mofokeng, 2018) © Eskom, Coal power station

5. Operation and Technology Coal-fired power stations operate by converting the chemical energy in coal into electricity through a multi-step process: Coal Preparation: Coal is crushed and pulverized to a fine powder to ensure efficient combustion. Combustion : The pulverized coal is burned in a boiler, producing heat that converts water into steam. Steam Generation : The high-pressure steam generated spins turbines connected to generators, producing electricity. Energy Conversion : The process transforms chemical energy into thermal energy, then mechanical energy, and finally electrical energy (Hinrichs and Kleinbach , 2006) © Wiki images, Coal plant operation

6. TURBINE WHEEL • The turbine is a round structure like a windmill. • The kinetic energy from the steam is changed into mechanical energy as the wheel turns . • The light ray of the turbine is connected to a rotating magnet in a generator that produces the electricity.

7. Environmental Impacts of Coal Power Station. Coal power station has a negative impact on air, water, and soil. Power plant combustion of coal releases dangerous gases into the air like Carbon monoxide. Mining coal requires a huge land and this results to deforestation. When site is being cleared, soil erosion, loss of biodiversity, and change in soil quality takes place. Dust pollution and noise pollution affects people’s health. ( Nimichandrappa & Polisegowdar , 2017)

9. Solar Energy Solar energy is the energy received by the Earth from the sun hence is called solar. Solar energy is in the form of solar radiation, which makes the production of solar electricity. This energy is eco-friendly and a renewable resource unlike coal. It can be used in remote area as it only requires sun. Reduces electricity bill.

10. Hydropower Flowing water creates energy which rotates turbines that can be captured and turned into electricity. Common Hydroelectric power plants use dam on a river to store water in a reservoir. Another type of hydroelectric power plant is a pumped storage plant which can even store power .
