2. 
Thermal power plants are also known
as Thermal power stations.
A thermal power station is a power plant in
which heat energy is converted to electric
power in which the prime mover is steam
drive.
Therefore, many thermal power plants are set
up near coal or oil fields.
What are thermal power plants?

3. 
 Fossil fuels like coal, oil, natural gases are burnt in
the boiler, a hot flue gases thus generated are used to
heat the feed water.
 A superheated steam is generated , this steam under
high pressure then expanded in stem turbine to
rotate the turbine.
 Turbine is coupled with the generator. When turbine
rotates, generator also rotates and produces
electricity. This arrangement of coupling turbine and
generator is called turbo-alternator.
Construction And Working Of
Thermal Power Plant

4. 
 Land requirement: The land for the thermal power
plant should be large enough so that the present
installation and future expansion of the plant can be
easily done. Cost and bearing capacity of the land
also plays important role while selecting a site for
thermal power plant.
 Water supply: Site should be near to the river so that
water required for the ash disposal, boiler feed
water, cooling and circulating water for condensers
should be available easily.
Site Selection For
Thermal Power Plant:

5. 
 Fuel supply: Plant should be near to the coal mines,
because cost of transmission of electricity is less than
cost of transportation of fuel.
 Ash disposal: Making ash ponds is a part of
installation of the plant. Enough space should be
there for ash ponds and water supply should
available for it.
 Transport facilities: For fuel supply – road and
railway links. Located near coal mines because if
quality of coal is poor transportation of coal is costly.

6. 
 Environment requirement: Thermal power plant
produces lot of pollution. Ash ponds may produce
water and air pollution, smoke from chimneys
produces air pollution. To avoid affects of pollution
site should be far from populated area.

7. 
 Advantages:
 1. Fuel cost of thermal power plant is relatively low.
 2. We can produce thermal energy almost every where in the
world.
 3. Heat production System is simple compared to other system.
 4. Overall system cost effective.
 5. Easy mechanism.
 6. Same heat could be reused.
 7. Easier Maintenance of power station.
 8. Use of water is prominent here, therefore, any places with
ample supply of water is a perfect location for installing a
thermal power station.
 9. Thermal power plant requires comparatively small space to
be installed.
Pros & Cons

8.  Disadvantages:
 1. Huge production of Carbon-di-oxide (CO2) in the atmosphere.
 2. Exhausted gases harms outside environment badly.
 3. Low overall efficiency.
 4. Thermal engines requires huge amount of lubricating oil that is
very expensive.
 5. Nuclear thermal power plant demands excessive amount of
water for cooling purpose.
 6. Coal type thermal power plant requires comparatively larger
duration before it supply generated power to the grid.
 7. This type of power station ultimately responsible for raise in sea
water level.
