- Car: Uses fossil fuel
- Heating boiler: Burns fossil fuels
- Air conditioner: No burning fossil fuel
- Locomotive: Uses fossil fuel
4 – Function of a steam turbine and power types used:
Steam turbine drives the alternator, producing movement. Used in thermal, nuclear, and solar thermal power plants.
5 – Enriched uranium in nuclear plants: Is it burned?
Yes, it’s the fuel that powers the process.
6 – Purpose of a hydroelectric turbine and fuel in a power plant?
The turbine moves the alternator, converting mechanical energy into electrical energy. The same process occurs in hydroelectric power plants.
7 – Differences between major, conventional, and nuclear power stations?
Combustion and water heating in nuclear plants occur due to nuclear fuel in the reactor core.
8 – Device transforming mechanical energy into electrical energy?
Alternator or generator.
9 – Effects of fossil fuels and electrical energy:
Fossil fuels cause soil and sea pollution, transport accidents, and contribute to the greenhouse effect and acid rain. Electrical energy risks include storage problems and radioactive contaminants.
Self-Assessment
2 – Group of devices producing electricity?
Turbine and alternator.
3 – Operation of a conventional combustion power plant:
Fuel is burned in a boiler, heating water into steam. The steam drives a turbine and alternator, generating electricity, which is then distributed by transformers.
4 – Operation of a hydraulic turbine:
Water at high speed turns the turbine shaft, which is connected to the alternator, converting movement into electricity.
5 – Relations:
- Boiler – Combustion thermal
- Nuclear reactor – Nuclear thermal
- Hydraulic turbine – Hydroelectric
- Steam turbine – Thermal combustion
- Alternator – Hydroelectric
6 – Role of transformer stations in electricity distribution?
They increase and decrease voltage.
7 – Renewable vs. Non-renewable sources:
- Coal: Non-renewable
- Uranium: Non-renewable
- Wind: Renewable
- Streams: Renewable
- Biomass: Renewable
8 – Alternative energy applications:
- Heating: Biomass energy
- Electrical: Biomass energy
- Transportation: Hydrogen energy
- Lights: Solar
- Hot water: Solar energy
9 – Composting process:
Fertilizer is obtained by separating inappropriate waste. The biomass of organic matter in the air causes certain gases. The decomposition process occurs under cover with ventilation and air treatment. Composting allows reuse of raw materials, creating a compost product for use as fertilizer.
10 – Solar panel calculation: 300:150 = 20. 20 plates should be installed.
11 – Role of photovoltaic solar panels:
Transform sunlight into electricity.
12 – Wind energy use:
Wind energy.
13 – Main uses of biomass:
Heat production, electricity production, and biofuel production.
14 – Energy produced inside the earth:
Geothermal energy.
15 – Hydrogen energy:
Hydrogen energy does not pollute because it is generated from a chemical reaction between hydrogen and oxygen, producing only water vapor as waste.
16 – Renewable energy items:
- Photovoltaic plate: Solar
- Turbine: Wind energy
- Organic matter: Biomass energy
- Tidal platforms: Tidal energy
