Ø Coal handling system
The coal handling system is
the most important functionary part thermal power plant. The
Steps involved in the coal
handling system are as follows:
·
Coal delivery
·
Unloading
·
Preliminary coal
preparation
·
Outdoor storage
·
Covered storage
·
In plant handling
·
Dust control system
·
Palavering
·
Feeding the coal into
furnace
Ø Steam generation system
Coal handling plant sends
the prepared coal to steam generation system. In this system, coal is burnt and
heat thus produced is transferred to water. The unit in which water is
converted into superheated steam. This section is comprised of various units
like furnace, boiler drum and tubes, super heater coils, reheater coils and
heat reclaiming device. Different types of boilers are available which can be
used. But now day’s high pressure boilers are being used in the thermal power
section. The maximum pressure in these boilers is about 126 kg/cm2.
Ø Power generation system
The steam produced in the
boiler is sent to the steam turbine where thermal energy is converted into
mechanical energy. The steam turbine consists of a rotor having a series of blades
on its circumference. The blades are made to withstand the action of steam and
the centrifugal force. The rotor is rotated by the steam striking against the
blades. As the steam expands in nozzle, it gains the high velocity. This energy
is converted into mechanical energy. As the steam turbine is directly coupled
to the dynamo and convert the mechanical energy into electrical energy.
Ø Feed water system
Raw water for power station
is taken from western Yamuna Canal (WYC) by a channel. This water is lifted by
water pumps and fed to clarifiers to remove the turbidity in water. The clear water
is stored in clear wells from where it is to be sending to water treatment
plant, cooling water system and service water system the water on treatment
plant is filter and demineralised.
The condensate from the
condenser is used as feed water to the boiler. Some water is lost throughout
the cycle from blow down leaks etc. The loss varies from 1 to 3 % during normal
operation and 5 % during start up period.
A separate water softening
plant is required to supply this from a river as well as a lake. The water
supplied by water softening plant is of very high quality (10-50) PPB silica and
less than 500 ppb total solid content).The impurities cause corrosion and
erosion of boiler tubes, turbine blade and blockage in the boiler tubes
resulting tube failure due to overheating.
Ø Ash handling system
In thermal power plant a
large quantity of ash is produced. The quantity of ash produced is about 10-20%
of total coal burnt. The as his first quenched and then disposed with help of
ash handling system.
Ø Draught system
The purpose of the drought
system is to supply require quantity of air for combustion and removed the
burnt products from the system for flowing of gases through different units, pressure
difference is essential. The difference of Pressure required to maintain
constant flow of air and to discharge the gases through the chimney to
atmosphere is known as drought.
Drought can be produced
naturally by chimney but it is not sufficient and mechanical drought systems of
induced and forced types are generally used. The ID (induced drought) fans and FD
(forced draught) are used for this purpose.
Ø Steam condenser system
The steam condenser system
basically improves the efficiency of the thermal power plant by decreasing the
exhausts the pressure of the stream below atmospheric pressure .The water obtained
from condensers is used in boilers again. The condenser system place vital role
in thermal power plant. Therfore, the reliability analysis of steam condenser
system is of great use. The results of this analysis can be used while
designing new plants.

-This innovative concept consists of hull and core where are held all 8 bteps of the work-flow which make the concept functional. The core has several gears and turbines which are responsible for these 8 steps (5 of them are dedicated to the turbo stages). The first step is fuel compression, followed by 2 cold turbo levels. The fourth step is where the fuel starts burning – combustion stage, which creates thrust for the next, 5th step – thrust step, which provides power to the planetary gears and turbines and moves the system. This step is followed by two hot turbo steps and the circle is enclosed by the final 8th step – bigger turbine. All this motion in a retrodynamic circumstance effect, wich is plus higher RPM speed by self motion. The Reaction at front of the action.
