1. A Seminar on
“THERMAL POWER PLANTS”
Guided By:- Presented by:-
Sir Rohit Mathews Divyansh Soni
Batch:-E.E.1

2. Contents
• Introduction
• Main Equipments
• Function held in Plant
• Advantages
• Disadvantages

3. Introduction
• In India 65% of total power is generated by the Thermal
Power Stations
• Kota Super Thermal Power Station i.e. K.S.T.P.S is situated
at Kota city at the bank of Chambal river. Its total
capacity is 1241 MW as at present with seven units
working with capacity.
• Having two unit of 2 x 110 MW = 220 MW
• Having three unit of 3 x 210 MW = 630 MW
• Having two unit of 2 x 195 MW = 390 MW

4. Basic Plant Layout

5. Main Equipments
• Boiler
• Turbine
• Super Heater & Re- Heater
• Condenser
• Alternator with exciter

6. Boiler
• These are designed for absorb maximum
amount of heat released.
• Boilers are further divided into two types-
• An Enclosed vessel in which water is heated.
1:-Fire tube boiler
2:-Water tube boiler

7. Types of Boilers
Fire tube boiler Water tube Boiler

8. Steam Turbine
• It’s a device which converts heat in steam to mechanical
power.
• It uses the principle that the steam when issuing from small
opening contains high velocity.
• This mechanical power is transferred to the Alternator by
shaft , Which converts this power to electrical power.
• It is of two types-
1:Impluse turbine
2:Reaction turbine

16. Advantages
• The fuel used is quite cheap.
• Less initial cost as compared to other generating
plants.
• It can be installed at any place irrespective of the
existence of coal. The coal can be transported to the
site of the plant by rail or road.
• It require less space as compared to Hydro power
plants.
• Cost of generation is less than that of diesel power
plants.

17. Disadvantages
• It pollutes the atmosphere due to production
of large amount of smoke and fumes.
• It is costlier in running cost as compared to
Hydro electric plants.
• The overall efficiency of thermal power plant
is less then 40 %.
