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.

INTRODUCTIONIndia is one of the world’s largest consumer of energyConventional sources: Thermal, Hydro and Nuclear.Non- conventional: Wind, solar, Geothermal, tidal.Installed capacity – 1,61,352MW Thermal = 95151.74MW Nuclear = 4,120MW Hydro = 36877.76MW RES = 13242.41MWAnnual power production – 680 billion KWH
Break up of PowerThermal Power Plants – 75%Hydro Electric Power Plants - 21%Nuclear Power Plants - 4%Installed wind power Generation – 9655MW30% to 40% of electrical power is lost in transmission and distribution
Main CircuitFuel And Ash CircuitAir And Gas CircuitFeed Water And Steam CircuitCooling Water Circuit
Fuel And Ash CircuitFuel 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 CircuitAir is required for combustion of fuel and is supplied through fansAir is passed through air preheater to extract energy from flue gases for proper burning of the fuelFlue gases have ash and several gases which are passed through the precipitator(dust collector) and go to atmosphere through chimney.
Feed Water And Steam CircuitSteam 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 turbineSteam is expanded in the turbine to run it. After which again it goes to boiler for reheating
Cooling Water CircuitTo condensate the steam, large quantity of cooling water is required which is taken from river or pondageAfter passing through the condenser, it is fed back to the river or Pondage
