A Seminar on “THERMAL POWER PLANTS”Guided By:- Presented by:-Sir Rohit Mathews Divyansh Soni Batch:-E.E.1
Contents• Introduction• Main Equipments• Function held in Plant• Advantages• Disadvantages
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
Basic Plant Layout
Main Equipments• Boiler• Turbine• Super Heater & Re- Heater• Condenser• Alternator with exciter
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 boiler2:-Water tube boiler
Types of BoilersFire tube boiler Water tube Boiler
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
Super Heater and Reheater

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.
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 %.
