3. INTRODUCTION:
A Thermal Power Plant converts the heat energy of coal into electrical
energy. Coal is burnt in a boiler which converts water into steam above
its critical for water of 705 °F(374 °C). The expansion of steam in turbine
produces mechanical power which drives the alternator coupled to the
turbine. Thermal power plant contribute maximum to the generation
of power for the country. Thermal power plants constitute 75.43% of
the totally installed captive and non-captive power generation in India.
In thermal generating stations coal,oil,natural gas etc.., are taken as
primary sources of energy.

7. 1.COAL HANDLING PLANT:

8. 2.PULVERIZING PLANT:
 In modern thermal power plant, coal is pulverized i.e. ground to dust like size carried to the
furnace in a stream of hot air. Pulverising is means of exposing a large surface area to the
action of oxygen and consequently helping combustion.

9. 3.DRAFT SYSTEM

10. 4.BOILER:
 A Boiler is a closed vessel in which
water under pressure, is converted
into steam.
 It is one of the major components of
a thermal power plant.
 Always designed to absorb maximum
amount of heat released in the
process of combustion.

11. 5.Ash handling plant:

12. 6.Turbines:
 A steam turbine is a device which extracts thermal energy from
pressurized steam and uses it to do mechanical work on a rotating output
shaft. Its modern manifestation was invented by Sir Charles Parsons in
1884.[1][2]

13. 7.Condensor:

14. 8.Cooling Towers:

15. 9.Feed Water Heater:
 By feeding water before boiler improves overall
efficiency of plant.
 Quantity of steam produced by boiler is increased.

16. 10.Economiser:

17. 11.Super heater and Reheater:

18. 12.Air Preheater:
 An Air preheater increases the
temperature of air supplied
for coal burning.
 And it drawn from the flue
gases.
 Air is drawn from the
atmosphere by the force of
draft fan.

19. THERMAL POWER PLANTS IN A.P
