Transcript of Fossil Fuel
and Djasper Lamsen Fossil-fuels HI! In this lesson about fossil-fuel generating systems you will learn:
How the energy system works
The pros and cons of this energy system
Where the energy resources will be going in the future
And we will be showing you a video of how fossil-fuel it uses energy
DJ How it Works: Fossil Fuel Power Fossil-Fuels are strong enough to potentially power the whole world Fossil-fuels such as coal are available in great amounts Fossil-fuels have a high calorific value. If you burn 1mg of fossil-fuel, a lot of energy is produced. Calorific Value
The number of calories or thermal units inside one unit of a substance, and the number of calories or thermal units that are emitted when the substance is burned. Fossil-fuels are non-renewable resources and can’t
be replaced once
they are finished Fossil fuels take millions of years to form Fossil fuels are the cause of Global warming, and can cause natural disasters such as earthquakes Fossil-fuels also give off gases that are harmful to pople and the environment. These gases are carbon monoxide and sulfur dioxide and they can produce acid rain
If we continue to abuse this energy resource, more harmful gas will be emitted into our atmosphere. This will increase the chance of acid rain.
Also, if we continue to use up this non-renewable resource, it will be completely used up very soon. We can also use this energy resource correctly to limit the amount of pollution being emitted into our atmosphere.
Future fossil-fuel energy technologies are being invented to reduce pollution and ultimately the chances of acid rain. Future of fossil-fuels Future of fossil-fuels HOW THIS ENERGY SYSTEM WORKS This is a fossil-fuel generating station. The fossil-
fuels undergo four
K In fossil-fuel generating stations, fossil-fuels burn to create heat. The heat that is created turns water in a boiler into steam. As the water turns into steam, pressure increases. The turbines in fossil-fuel generating stations are powered by steam. This pressurized steam that is created pushes the turbine causing it to spin rapidly. The turbine then begins to turn the generator because it is attached to the turbine. The turbine causes the generator to spin very fast. Electricity is generated by magnets that spin very fast. These magnets are inside copper coils, and the movement of the magnets in the coils causes them to release electrons.
These electrons then flow in the form of electricity. Also, the waste gases produced by the burning fossil-fuels rise and exit through the cooling towers Pros and Cons The most common uses of fossil-fuels are:
Heating This is because when coal is pulled out of the ground and sometimes out from underneath mountains, a new ecological imbalance is created, therefore causing earthquakes. New technologies are coming together to try to bridge the large difference between fossil fuel consumption and responsible use. Fossil-fuels are made from fossilized plants that undergo high pressure over millions of years. Common fossil fuels include petroleum-based fuels also known as oil, natural gas and coal. All these types of fuels burn. This means they are combustible. When fossil-fuels burn, they release heat and waste gasses. Fossil-fuel generating stations use that heat to generate electricity.
M O k K K U U O U O U Hydrogen is a very clean form of energy. Hydrogen is efficient and renewable. During the fossil-fuel generating station’s process of burning coal to heat water in the boiler, Gasified coal syngas (synthesis gas) is produced. Syngas is a combination of hydrogen, carbon monoxide and carbon dioxide. A procedure is used to boost the hydrogen content of this gas while removing all other contents. The result is a stream of only hydrogen contents. K U U O U O O U In conclusion, fossil-fuels are a non-renewable resource that must be consumed wisely. In fossil-fuel generating stations coal is burned to turn water into steam, which turns the turbine and generator. The generator consists of magnets in coils that turn and release electrons, resulting in a flow of electrons and therefore producing electricity.
M Finally, the future of fossil-fuels relies on us. In order for this resource to remain plentiful and for less pollution, we have to use new technology to eliminate harmful gas and come up with new ways to conserve this resource.
