Thermal power plant
is a place which the Electricity is generated by heating energy is converted into
In this technology of power generation heat energy is used
to rotate the shaft of the Generator. The truth we all know the generator a
device which converts mechanical energy into electrical energy. In this technology
of power generation heat energy is used to rotate the shaft of the Generator.
We all know the generator a device or which converts mechanical energy into
electrical energy. A Steam turbine is a device that extracts thermal energy
from pressurized steam and do
mechanical work on a rotating output shaft. The turbine takes the input from high energy fluid. The turbine blades
are in airfoil shape. High
capacity power plants use different stages of steam Turbines such as
High pressure Turbines
Intermediate Pressure Turbines
Low Pressure Turbines
We are operating the generator by taking back the low
pressure and low temperature steam to
high Pressure, high temperature we repeat the process of operating generating with high pressure and high
temperature to raise the pressure we can use a compressor.
Compressing pressure is a highly complex process so we convert steam to liquid and increase
or boost the pressure, so focus on this
we use condensed heat exchangers in low pressure Turbines stream is going to
the condenser tubes and steam reject heat of the liquid stream and condense. Now
we can use a pump to increase the pressure of the steam so the high pressure
high temperature remains original state.
The next process is to increase the heat of the steam to the original value so
we use a boiler. The output of the compressor goes to the boiler.
Water tube boiler is used to polarize coal as fuel in the boiler.Incoming water initially passes
through Economizer .
Economizers in steam power plants is to capture the waste
heat from boiler stack gases (flue gas) and transfer it to the boiler
feedwater. This raises the temperature of the boiler feed water, lowering the
needed energy input, in turn reducing the firing rates needed for the rated
boiler output. Water will gets energy from the flue gas.
Then water flows through down comer and water valve transforms into steam. Pure
steam is separated at steam draw. So at
this point steam has high pressure and high temperature. The working fluid is
at original state. This steam is input to work steam turbine and the
process is done over for complete the Power
Generation Technology. The efficiency of Technology is about 20% to 25%.To
increase the efficiency of the system Super Heating technic is used. In this
process the Super heated steam is an extremely high temperature vapor generated
by heating the saturated steam obtained from the boiling water.
Cooling Systems are used to cool the generator and other
systems that increase the efficiency of the thermal power plant. By using all
these systems efficiency is improved up to 33% to 48%.
