Transcript

  • 1. Geo – earth, Therme - Heat MUIC ICPY211 - Sirirat, Napat, Rishab Trimester 1 2009-2010
  • 2. Reykjavik, Iceland, one of the cleanest city of the world
  • 3. Intense heat flow from inside the Earth (core temperature 4000° C to 7000 °C) Underlying Mantle, partially molten rock A lava fountain is an example of the amount of heat stored in the Earth
  • 4. Water sweep through cracks and fissure and comes in contact with hot rocks, may reach a temperature of 350 ° C The Pohutu Geyser in New Zealand erupts with a natural blast of the Earth's interior heat.
  • 5. Geothermal heat pumps make use of the constant temperature that exists just under the Earth's surface.
  • 6. 1. Dry Steam Power Plant – produce the energy directly from underground stream.
  • 7. 2. Flash Steam Power Plant – the hot water, over 350 F, is released from the pressure and is kept in the tank. The water is heated in the tank and turns to stream.
  • 8. 3. Binary Steam Power Plant – the hot water with 100 F is come to a heat exchanger and mix with a secondary liquid.
  • 9. •Renewable energy • No serious pollution • Lower maintenance cost. • Require less area of land • More reliable, can run 24 hours a day, 365 days a year •High cost of set up •Antifreeze solutions are slightly toxic
