7. COAL HANDLING PLANT By wagon Tripler By means of two Coal is supplied
The coal is drawn
Into underground hopper
By means of two
Belts coal is transferred
To the Conveyer
Coal is supplied
Through rail
Track by own trains
From nozzle
coal Is
discharged to
furnace
Coal is taken
to Coal nozzle
In wind box assembly
Now coal is fed to Mills
Where coal is
Crushed in pulverized
form
Now coal is transferred to
Crushing house and
stored
to bunkers

8. BOILER
A boiler is a closed vessel in which water under pressure is converted into steam.
A boiler is always designed to absorb maximum amount of heat released in process of combustion.
This is transferred to the boiler by all the three modes of heat transfer i.e. conduction, convection and radiation.

10. STEAM TURBINE Steam Turbine used is mainly of three types-:
Turbine is a machine which converts the potential or kinetic energy of the steam into mechanical power by virtue of dynamic action of steam.
Steam Turbine used is mainly of three types-:
FIRST STAGE\HIGH PRESSURE TURBINE
SECOND STAGE\INTERMEDIATE TURBINE
THIRD STAGE\LOW PRESSURE TURBINE

11. PROCESS OF STEAM GENERATION

12. TURBO GENERATOR SPECIFICATIONS Manufactured by-:BHEL
Rated Speed : RPM
Power Output -:110 MW
Power factor :0.8
Rated voltage -:1000V
Rated current :7200A
Cooling Element -:6

13. DEaRATOR Dearator is a device which is widely
used for the removal of air and
other gases from the feed water
to steam generating boilers. in
particular dissolved oxygen in
Boiler feed waters will cause
serious corrosion damage in
steam system by attaching to the
walls of metal piping and other
metallic equipment and forming
oxides.

15. Electro Static Precipitator
To remove fly ash from flue gases electro static precipitator is used.
They have collection efficiency of over 99.5%. The efficiency depends on various Factors such as velocity of flow, quantity of gas, resistivity of ash, voltage of fields, precipitators etc.

16. MAIN PARTS OF ESP :
Electrostatic precipitator consists of following parts:-
Casing
Supply system
Emitting electrodes
Collecting electrodes
Wrapping system
Collecting basket

17. PRINCIPLE OF OPERATION
Electrodes at high voltage create a corona effect
(ionized atmosphere) surrounding them. This charges the passing
particles. Once charged, particles are subject to a transverse
electrostatic force that pulls them toward the collecting plates.
Plates are periodically rapped (vibrated) to make the collected
particles fall down into a receiver basket
