Gas power

  1. 1. GAS POWER <br />GENERATION<br />Chanakya Daparthy-16<br />T.V.Krishna Murthy-51<br />P.Sudhakar Yadav-58<br />
  2. 2. 1.AVAILABILITY OF NATURAL GAS<br />2.TECHNOLOGY FOR CONVERSION<br />
  3. 3. INDIA IS ONE OF TOP PRODUCERS OF GAS …..!<br />
  4. 4. GAS RESERVES IN THE WORLD<br />
  5. 5. <ul><li>Natural gas, because of its clean burning nature, </li></ul>has become a very popular fuel for the generation of electricity. <br /><ul><li>In the 1970's and 80's, the choices for most electric utility generators were </li></ul>large coal or nuclear powered plants; but, due to economic, environmental, <br />and technological changes, natural gas has become the fuel of choice for new power plants. <br /><ul><li>In fact, in 2009, 23,475 MW (megawatts) of new generation </li></ul>capacity are planned in the U.S. Of this, over 50%, <br />or 12,334 MW will be natural gas fired additions.<br />
  6. 6. What is the need ???????<br />Plant setup is very easy<br />No complications in operation<br />Eco-friendly ,ash disposal is minimum & greenhouse gas emission is 50% less than that of coal n oil<br />Many a variety of fuels like natural gas, liquified fuels and solidified fuels can be used<br />
  7. 7. Basic gas turbineworking<br />
  8. 8. <ul><li>The basic principle of the Combined Cycle is simple: burning gas in a gas turbine (GT)</li></ul>produces not only power - which can be converted to electric power by a coupled generator but also fairly hot exhaust gases. Routing these gases through a water-cooled heat exchanger produces steam, which can be turned into electric power with a coupled steam turbine and generator.<br /><ul><li>This set-up of Gas Turbine, waste-heat boiler, steam turbine and generators is called a</li></ul>combined cycle<br />

  10. 10. Power plant setup<br />
  11. 11. The unitary operations in the process is based are:<br />· 1 Compressor<br />· 1 Gas turbine<br />· 1 Steam turbine<br />· HRSG (Heat Recovery Steam Generator)<br />· 1 Condensation stage (exchanger and a tank)<br />· Energy generator.<br />
  12. 12. Two big parts can differ; a first one, referred to the gas cycle, where energy will be<br />liberated that will serve to be able to carry out the second part, the steam cycle. The air<br />enters in the plant coming from the atmosphere goes by a compressor, which the pressure increases from the atmospheric one up to 23 bars. The compressed air passes to a combustion camera that blended with natural gas, the combustion takes place.<br />
  13. 13. <ul><li>The generated hot gases of combustion go by the gas turbine, where they expand, arriving</li></ul> another time to the atmospheric pressure. <br /><ul><li>These go toward to the HRSG, which recovers the great quantity of thermal energy that subtracts in them to produce steam.
  14. 14. This is distributed among the circuit of high pressure to 160 bars.
  15. 15. The steam flow of high pressure will be good to feed the steam turbine.
  16. 16. The steam expands from 160 up to 1 bar of exit.
  17. 17. The final stage of this process concerns to the condensation and recirculation of the steam</li></ul> water. <br />
