2. 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 = 95151.74MW
Nuclear = 4,120MW
Hydro = 36877.76MW
RES = 13242.41MW
Annual power production – 680 billion KWH

3. 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

5. Main Circuit
Fuel And Ash Circuit
Air And Gas Circuit
Feed Water And Steam Circuit
Cooling Water Circuit

6. 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

7. 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.

8. 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

9. 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
