Transcript

  • 1. Combined Cycle Power Plant David Grenier Master GI 2
  • 2. Table of content Introduction / Context How it works Why do they use this technology Disadvantages to use natural gas The situation in France Conclusion
  • 3. 1. Combined Cycle Power Plant (CCPP) Intro Context Consumes 2. one-third less Working Allows natural gas & to… CO2 / 3. generated Why used kW.h CCPP Last 4. Natural gas technologiesDisadvantages 5. Protect French’s environnement situation 6. 3 mainConclusion leaders 1
  • 4. 1. Combined Cycle Power Plant (CCPP) Intro Context 2 Engineering Departments 2. Working 3. Why used CCPP Concurrent Product Power Plan Engineering Engineering (PE): Engineering (PPE): 4. Natural gasDisadvantages Shaft line Shaft line’s environment Piping More than 100 items Ex : - Gas turbine 5. French’s - Generator Air Filter situation - Steam turbine - … Fire Fighting Protection 6.Conclusion
  • 5. 1. Combined Cycle Power Plant (CCPP) Intro Context Natural Gas - More versatile than coal & oil - Can be used in 90% of energy applications 2. Working 3. Why used CCPP 4. Natural gasDisadvantages Electricity 5. French’s situation 6.Conclusion
  • 6. 1. Continual Improvement of technology Intro Context 2. Working Higher increase 3. Why used Customer’s demand CCPP 4. Natural gasDisadvantages CCPP’s Advantages : - Industry-Leading Start Capability : start capability of 28 minutes for hot starts 5. and start reliability of greater than 98% French’s - Fast Ramp Rates : 51 MW per minute ramping capability and improved load situation adjustment capability - Improved Turndown : turndown of less than 40% of base load within emissions compliance 6. - Fuel Flexibility : to have both a distillate fuel back-up option and a modifiedConclusion wobbe index variation of +/- 10%. - To reduce CO2 emissions : above 50 %
  • 7. 1. Disadvantages Intro Context 2. Limited quantity of Higher operating Working natural gas cost 3. Transport is Why used costly CCPP To be fully 4. consumed by Highly Natural gas 2070Disadvantages inflammable substance 5. French’s situation - a colorless and an odorless substance, detection of gas leaks can be difficult - The process of extraction of natural gas involves making large cavities in the ground. The cavities result in an increase in soil pressure and can cause the 6. ground to sinkConclusion - Natural gas occupies four times the space of a gasoline-equivalent energy
  • 8. 1. The situation in France Intro Context 2. Electrical production by natural gas Working 3. England, Spai Why used FFrance : n, Austria : CCPP only 1% 35% FItaly : 40% 4. Natural gasDisadvantages French objective : 5. French’s - To modernize production’s park of electricity situation - Since 2009 : Project to built every CCPP - In order to reduce waste and CO2 emissions - There will be 10 CCPP by 2012 6.Conclusion - Three of them are currently being built
  • 9. 1. Political Intro Context France becomes first country to ban extraction of natural gas by fracking : The French parliament 2. voted on June 30 (2011) to ban the controversial Working technique for extracting natural gas from shale rock deposits known as hydraulic fracturing, or 3. fracking Why used CCPP Sourcing of natural gas by France Norway Holland 4. Natural gasDisadvantages Russia 5. French’s Others situation French 6. productionConclusion Algeria
  • 10. Natural Gas Gasoline-equivalent 1. energy Intro Context 4x 1x 2. Working 3. Costs of treatment, storage and Why used CCPP transport are expensives 4. Natural gasDisadvantages 5. French’s situation 6.Conclusion Natural gas is advantageous for its clean combustion process and its availability. There are some disadvantages of natural gas but many companies choose netherless this energy for use as a fuel.
