3. Introduction 1. Suratgarh thermal power station is the first super
thermal power Station of Rajasthan with total
installed capacity of 1500 MW.
2. Suratgarh super thermal power station is located
27 km away from Suratgarh town in
Ganganagar Dist. on the left bank of IGNP at Up
Stream of Suratgarh Barrage.
3.This station is operated and maintained by Rajasthan
Vidhyt Utpadan Nigam Limited.

7. Ash Handling Plant
Ash in the coal varies from 5% in good quality coals to
About 40% in poor quality coals. *
Ash handling plant having the following operation
Removal of ash from the furnace ash hoppers.
ii. Transfer of this ash to a fill or storage and
iii. disposal of stored ash

8. Turbine
In a Thermal Power Plant generally 3 turbines are used to increase the efficiency.
High Pressure Turbine(HPT): The superheated steam is directly fed to this turbine to rotate it.
Intermediate Pressure Turbine(IPT): The out put from the HPT is reheated in a reheated(RH) and used to rotate IPT .
Low Pressure Turbine(LPT): The Exhausted steam from the IPT is directly fed to rotate the shaft of LPT.

9. Boiler
In boiler heat energy is released from the combustion of fossils fuel and heat is transferred to different fluids in the system.
Boilers are of two types-
*Fire tube boiler.
*Water tube boiler.
Mode Of Heat Mediam
Conduction
Convection
Radiation

10. Condenser
The purpose is to condense the outlet (or exhaust) steam from steam turbine to obtain maximum efficiency and also to get the condensed steam in the form of pure water, otherwise known as condensate, back to steam generator or (boiler) as boiler feed water.

11. Cooling towers and ponds
A condenser needs huge quantity of water to condense the steam . Typically a 2000MW plant needs about 1500MGallon of water.
Cooling tower is a steel or concrete hyperbolic structure having a reservoir at the base for storage of cooled water
Height of the cooling tower may be 150 m or so and diameter at the base is 150 m

12. Economiser
Flue gases coming out of the boiler carry lot of heat. An economiser extracts a part of this heat from flue gases and uses it for heating feed water. This use of economiser results in saving coal consumption and higher boiler efficiency

13. Super-heater
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

14. Air Pre Heaters
Air pre-heater pre-heats (increases the temperature) the air supply to the furnace with the help of hot the gases.
It is installed between the economiser and the chimney.

15. Generator
The Synchronous Generator is used to Generate power by connecting the shaft of the Turbine to the shaft of the generator which cuts the magnetic flux producing Emf.
The Generated Voltage will generally 11KV to 20 KV max.
The Generated Voltage is stepped up by connecting Step up transformer and is transmitted and is also used for Auxiliary purposes

16. Transformers
It is a device that transfers electric energy from one alternating-current circuit to one or more other circuits,
either increasing or reducing the voltage. Uses for transformers.
Step up transformer.
Step down transformer.
Transformers act through electromagnetic
 induction; current in the primary coil induces
current in the secondary coil.

17. Control Room
The various controls performed from here are voltages adjustment, load control, emergency tripping of turbines etc. *
