ABSTRACT
Everybody must be having a thought that a thermal power plant is a place where electricity
is produced. But do you know how it is produced? The answer as it seems is not so easy.Here we use different fuels i.e. coal, natural gas, uranium (radioactive element. The
chemical energy stored is converted to heat energy which forms the input of power plant
and electrical energy produced by the generator is the output. !n a convectional power plant
the energy is first converted to a mechanical work and then is converted to electrical
energy.
The first energy conversion takes in what is called a Boiler or "team #enerator, the second
in what is called a Turbine and the last conversion takes place in the #enerator.
$ow one may imagine how ! know so much. !t%s simple& ! had an opportunity to view all

t5 mechanical power produced by turbine
This facility first produces steam in a boiler (steam generator. This steam is used to rotate
turbine which is connected to a shaft of generator. Hence electricity is produced here. The
used steam is then condensed in a condenser, and the condensed liuid is used again in the
steam generator.

an isolator. Three phase system is used for the power transmission. Each generator has its
own switchyard and transmission arrangement.
'.1. PROCEDURE:'.1. PROCEDURE:
The basic understanding of the modern thermal power station in terms of ma4or systems
involved can be done under three basic heads vi>. generating steam from coal, conversion
of thermal energy to mechanical power and generation C load dispatch of electric power.
1. Co! "o S"e!2:
The coal is burnt at the rate up to -11 tonnes per hour. ing mill, where it is powdered
as fine as flour. 6ir is drawn in to the boiler house by drought fan and passed through *re=
heaters. "ome air is passed directly to bunker and rest, through primary air fan, to
pulveri>ing mill where it is miFed with powdered coal. The miFture is then carried to
bunker of furnace where it miFes with rest of the air and burns to great heat. This heats
circulating water and produces steam, which passes to steam drum at very high pressure.
The steam is then heated further in the "uperheater and fed to high pressure cylinder of
steam turbine. The steam is then passed to other cylinders of turbine through re=heater. The
spent steam is sent to condenser, where it turns back to water called condensate.
+ondensate is sent to lower part of steam drum through feed heater and economi>er. The
flue gases leaving boiler are used for heating purpose in feed heater, economi>er, and air
*re=heater. The flue gases are then passed to electro=static precipitator and then, through
draught fan, to chimney.
+oal from the coal wagons is unloaded in the coal handling plant. This coal is transported
upto the raw coal bunkers with the help of belt conveyors. +oal is transported to bowl mills
by coal feeders. The coal is pulveri>ed in the bowl mill, where it is ground to a powder
form. The mill consists of a round metallic table on which coal particles fall. This table is
rotated with the help of a motor. There are three large steel rollers, which are spaced '-1
apart. hen there is no coal, these rollers do not rotate but when the coal is fed to the table
it packs up between the roller and the table and these forces the roller to rotate. +oal is
crushed by the crushing action between the rollers and the rotating table. This crushed coal

is taken away to the furnace through coal pipes with the help of hot and cold air miFture
from the primary air (*.6. fan. The *.6. fan takes atmospheric air, a part of which is sent
to the air pre=heaters for heating while a part goes directly to the mill for temperature
control. 6tmospheric air from forced draft (er and reaches the boiler drum.
ater from the drum passes through down comers and goes to bottom ring header. ater
from the bottom ring header is divided to all the four sides of the furnace. Gue to heat and
the density difference water rises up in the water wall tubes. ater is partly converted into
steam as it rises up in the furnace. This steam and water miFture is again taken to the boiler
drum where the steam is separated from water. ater follows the same path while steam is
sent to the super heaters for superheating. The super heaters are located inside the furnace
and the steam is superheated (9)1+ and finally goes to the turbine.

turbine shaft, operates the control valves to regulate the amount of steam used (this depends
upon the speed of the turbine and the amount of electricity reuired from the generator.
"team from the control valves enters the high pressure cylinder of the turbine, where it
passes through a ring of stationary blades fiFed to the cylindrical wall. These act as no>>les
and direct the steam into a second ring of moving blades mounted on a disc secured to the
turbine shaft. This second ring turns the shafts as a result of the force of the steam. The
stationary and moving blades together constitute a stage% of the turbine and in practice
many stages are necessary, so that the cylinder contains a number of rings of stationary
blades with rings of moving blades arranged between them. The steam passes through each
stage in turn until it reaches the end of the high pressure cylinder and in its passage some of
its heat energy is changed into mechanical energy. The steam leaving the high pressure
cylinder goes back to the boiler for reheating and returns by a further pipe to the
intermediate pressure cylinder. Here it passes through another series of stationary and
moving blades. ed. er and the boiler for reconversion into steam. The cooling
water drawn from the reservoir is returned directly to the source after use.

The shaft is connected to an alternator%s armature. Thus the armature is rotated and electric
current is produced in the stator%s windings. The generated electricity is of order -9,111
volts. The turbine shaft is mechanically coupled to the generator rotor shaft through thrust
bearings. The steam rotates the turbine at 2111 rpm thus the rotor of the generator also
rotates at 2111 rpm. This speed is necessary to generate electricity at a freuency of 91 H>
with a two pole turbo= generator. The rotor carries the field winding over it. This field

winding is eFcited by a G+ eFcitation system. The supply to the eFcitation system is tapped
from the unit auFiliary transformer. The fluF generated by this field current cuts the
armature coil. The armature coil is star= star connected and is induced with three phase emf.
The emf is tapped with the help of slip rings and brushes. This emf is carried over to the
generator transformer through a bus duct. The bus duct is voltage transformer grounded.
