Energy power stations

  1. 1. Electric power plants Paola Caro Domínguez Javier Borrallo Fernández 3ºA Curso 2011-2012
  2. 2. Index 9-18Non-conventional electric power plans3-8Conventional electric powerplants 10.Types of non-conventional electric power plants.4.nuclear power plant 11.Wind power plants5.Fossil fuel thermal power plant 12.Solar power plants6.Combined cycle power plant 13.Geotheral power plants7.Combined cycle power plantwork. 14.Biomass thermal power plant8.Hydroelecctric power plant 16 -17.Enviromental impact 18.From air to water.
  3. 3. Conventional electricpower plantsThey produce most of the energy that we use.Types:● Nuclear power plants.● Fossil fuel thermal power plants.● Hydroelectric power plants.
  4. 4. Nuclear power plants●They break down the fuel and it produces largeamounts of heat this heat is used to produce ahigh pressure stream that moves theturbines, this turbines are connected to agenerator that produces electricity.● Main fuel: Uranium.● Advantages:high return on their energy production.
  5. 5. Fossil fuel thermal powerplants● In this type of power ● They usually burn plants the water is coal but now is heated to its boiling increasingly burning point. It generates natural gasd steam and this because it produces steam is used to the least pollution. move the turbine that is connected to the generator.
  6. 6. Combined cycle power plants● This type of power ● First the gas is plants generates mixed with the air electrycity as a result and its burnt. It of combinining two generates electricity. Hot gases are cycles, a cycle that transported to the uses air and gas and recovery boiler a conventional where they transfer thermal cycle their energy to the water in the second cycle.
  7. 7. Hydroelectric power plants● It uses the force of water that is stored ● There are two types in a dam. The water of hydraulic energy moves a turbine and depending on the produces kinetic destination of the energy and then this water: gravity or energy is pump. transformed into electricity
  8. 8. Non-conventional electricpower plants● Advantages:They contaminate less than conventional power plants,they use renewable sources and reduce the energy dependence.● Disadvantages:they generate much less energy
  9. 9. Types of non-conventionalelectric power plants ● Wind power plants and wind farms ● Solar power pants ● Geothermal power plants ● Biomass Thermal power plants ● Ocean power plants
  10. 10. Wind power plants and windfarms● They use the movement of the wind,to move blades which generate electricity thanks to a transformation center at the bottom of the tower where the blades are.● Wind farms can only be installed in places with good wind conditions● A wind power plant produces between 1MW and 10MW
  11. 11. Solar power plants ● They use the energy from the sun to produce electricity ● Photovoltaic power● Photo-thermal power plants plants ● The solar radiations● The heat generated are transform directly by the solar into electricity by radiations produces photovoltaic panels. stream which moves ● The isolated power p a rotor conected to a ● lants are smaller. generator.
  12. 12. Geothermal power plants.● They use the heats found at the deep of the Earth to produce energy.● These energy cn be used:● Directly:hot water,heating and industrial uses.● Indirectly:the heat generates stream which produce electricity
  13. 13. Biomass thermal powerplants.● Energy is produced by burning organic wastes,the steam from the burning moves a turbine conected to a generator.
  14. 14. Ocean power plants.● These power plants use the force of waves and tides to produce energy.● They are in a experimental fase so they dont produce too much energy.
  15. 15. From wind to water Eole water,the French research companyhas created a new air rotor which can convert the whater steam in the air into drinking water. The air enters into the turbine and goes into an electric cooling compressor which condense the water in the air. One turbine can produce up to1,000 liters of water every day
