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

STEAM TURBINE

o
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

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.

BLOCK DIAGRAM OF ASH HANLING PLANT
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.
Electrostatic precipitator consists
of following parts:Casing
Supply system
Emitting electrodes
Collecting electrodes
Wrapping system
Collecting basket
Principle:
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
