  • Per capita means how much a person receives. India’s population is 1.17 billion as of July’09. Total Production = 1,49,390MW
  • Flue gas – gas which comes out after burning a fuel and it contains a lot of sulphur.

  • (Steam power Plant)
  • INTRODUCTION
    • India is one of the world’s largest consumer of energy
    • Conventional sources: Thermal, Hydro and Nuclear.
    • Non- conventional: Wind, solar, Geothermal, tidal.
    • Installed capacity – 1,61,352MW
      • Thermal = 95151.74 MW
      • Nuclear = 4,120MW
      • Hydro = 36877.76 MW
      • RES = 13242.41 MW
    • Annual power production – 680 billion KWH
  • Break up of Power
    • Thermal Power Plants – 75%
    • Hydro Electric Power Plants - 21%
    • Nuclear Power Plants - 4%
    • Installed wind power Generation – 9655MW
    • 30% to 40% of electrical power is lost in transmission and distribution
  •  
  • STRUCTURE OF POWER SYSTEM
    • Power system owned by state electricity boards.
    • Private sector utilities operate in Mumbai, Kolkata, Ahmedabad
    • Regional electricity boards – Northern, Southern, Eastern, Western, North-eastern.
    • Power Grid corporation- Central.
  • Thermal Power Plants
    • Installed Capacity – 93,392.64MW
    • Coal based – 77,458.88MW
    • Gas Based – 14,734.01MW
    • Oil Based – 1199.75MW
  • General Layout of Thermal Power Station
  • Main Components
    • Fuel Handling Unit
    • Ash Handling Unit
    • Boiler Unit
    • Feed Water Unit
    • Cooling Water Unit
    • Generator Unit
    • Turbine Unit
  • Main Circuit
    • Fuel And Ash Circuit
    • Air And Gas Circuit
    • Feed Water And Steam Circuit
    • Cooling Water Circuit
  • Fuel And Ash Circuit
    • Fuel stored and fed to the boiler through conveyor belts. Broken down into proper shape for complete burning.
    • Ash thus generated after burning is removed from the boiler through ash handling equipment
  • Air And Gas Circuit
    • Air is required for combustion of fuel and is supplied through fans
    • Air is passed through air preheater to extract energy from flue gases for proper burning of the fuel
    • Flue gases have ash and several gases which are passed through the precipitator(dust collector) and go to atmosphere through chimney.
  • Feed Water And Steam Circuit
    • Steam Converted to water by condenser.
    • Water is demineralized & hence not wasted to have better economic operation of the plant.
    • Some part of steam and water is lost while passing through different parts.
    • Boiler feed pump feeds water into the boiler drum where it is heated to form steam.
    • Wet steam is again heated in super heater before passing through the turbine
    • Steam is expanded in the turbine to run it. After which again it goes to boiler for reheating
  • Cooling Water Circuit
    • To condensate the steam, large quantity of cooling water is required which is taken from river or pondage
    • After passing through the condenser, it is fed back to the river or Pondage
  • Boiler
  • Turbine
  • Turbine – Full View
  • Economizer
  • Selection Of site
    • Availability of cheap land.
    • Availability of water.
    • Availability of fuel.
    • Possibility of future expansion of the plant.
    • Away from the urban areas due to pollution.
    • The initial cost of plant.
    • Magnitude and nature of load to be handled.
