2. INTRODUCTION
 SSTPS is situated near village Thukrana about 27Km south east of Suratgarh
town in Shri Ganaganager Distt.
 This Plant has six units each having capacity to produce 250 MW.
 Whole capacity of plant is 1500 MW.
 This plant is operated by coal which is provided from MP and JHARKHAND
Coal mines.
 The coal requirement for each unit is 150 tonne per day
 Water supply is provided to it from INDRA GHANDI CANNEL.
 It Supplies electricity to areas of northen Rajasthan like Bikaner, Ratangarh,
Ganganagar and Hanumangarh.

5. MAIN COMPONENTS
 Main components of power plant is:
1. Coal handling plant
2. Boiler
3. Turbine
4. Condenser
The other components of the steam power plant is:
1. super heater
2. Economizer
3. Air preheater
4. Feed water pump

6. PRINCIPLE OF WORKING
There are four processes in the Rankine cycle.
Process 1-2: The working fluid is pumped from low to high
pressure. As the fluid is a liquid at this stage, the pump requires
little input energy.
Process 2-3: The high pressure liquid enters a boiler where it is
heated at constant pressure by an external heat source to become
a dry saturated vapour.
Process 3-4: The dry saturated vapour expands through a turbine
generating power. This decreases the temperature and pressure of
the vapour.
Process 4-1: The wet vapour then enters a condenser where it is
condensed at a constant pressure to become a saturated liquid.

8. COAL HANDLING PLANT
 The coal used in plant is between grade Bituminous and Anthracite.
 It is a plant where the coal is store from the coal bunkers.
 In this plant the coal is then process through the pulverizing process where by
the help of crushers the coal is change in fine powder form. Above whole
process is processed in milling plant.
 Pulverizing process allows coal to burn more quickly.
 After pulverizing process the coal is then process to the boiler by the help of
conveyer belts.
 The requirement of coal in plant is 18000 tonne/day.

9. BOILER
 It is a close vassal which converts the fuel energy into steam energy. The
fuel may be furnace oil, diesel oil, natural gas or coal.
 IT is generally made of alloy steel.
 In it the pulverized coal is burn and converts the water into superheated
steam by the help of water tube heat exchanger.
 The steam output of 375 tons/hour at 138 Kg/cm2 pressure and 540℃
temperature.
 The ash from boiler is collected in the ash handling plant.
 Specification of boiler is:
Total Water Flow 780.5 T/Hr.
Steam Temperature 540ºC
Coal Requirement for 250MW 160 T/Hr.

10. SUPERHEATER
 A Super-heater is a device which removes the last traces of moisture from the saturated steam
leaving the boiler tubes and also increases its temperature above the saturation temperature. For
this purpose, the heat of combustion gases from the furnace is utilized. Super-heaters consists of
groups of tubes made of steel.
 Superheater provides dry steam for impact on turbine.
 This is necessary for protect the turbine blades from the corrosion.
 It is a device which can be mounted in the boiler.
 The outside diameter of superheater tubes ranging b/w 25mm to 64mm.

11. ECONOMIZER AND AIR-PREHEATER
 Economizer and Air-preheater are the devices which use to
initially heat the water and air before feed to boiler.
 Economizer is placed before the air-preheater which can be
use to preheat the water to a suitable temp, which can
increase the efficiency of boiler.
 Air-preheater is a device which can preheat the air before it
feed to combustion chamber for burning.
 The coal has burn with the chemical reaction of carbon and
oxygen from air.
 This process requires a min. temp. for burning which can
be provided by preheating of air.

12. TURBINE
 A steam turbine is a device that extracts thermal energy
from pressurized steam and uses it to do mechanical work
on a rotating output shaft.
 The work produced by a turbine can be used for generating
electrical power when combined with a generator.
 A turbine is a turbo machine with at least one moving part
called a rotor assembly, which is a shaft or drum with blades
attached. Moving fluid acts on the blades so that they move
and impart rotational energy to the rotor.
 There are generally three types of turbines:
1. High pressure turbine
2. Low pressure turbine
3. Intermediate pressure turbine

13.  High pressure turbine: The HP turbine consists of 25 reaction stages. The
moving and stationary blades are inserted into appropriately shapes into inner
and the shaft.
 Intermediate pressure turbine: The steam from HP turbine after reheating
enter the inner casing from above and below through two inlet nozzles.
 The IP turbine consists of 20 reaction stage per flow. The moving and stationary
blades are inserted in appropriately shaped grooves in shaft and inner casing.
 Low pressure turbine: Steam admitted to LP from IP turbine flow into the inner
casing from both sides through steam inlet nozzles.

14. Turbine

15. CONDENSOR
 IT is a device which is use to cool the steam and
change it into water after leaving the turbine.
 In the SSTPS surface condenser is use.
 Condensation of exhaust steam takes place on the
outer surface of the tubes, which are cooled by
water flowing inside them.
 The condenser essentially consist of a shell, which
enclose the steam space. Tubes carrying cooling
water pass through the steam space.

16. FEED WATER PUMP
 IT is a pump which increases the pressure of
the water and feed it to the boiler.
 It can be operated with the turbine.
 The water supplies buy feed water pump is
either fresh water or the condensate water.
