1. PREFACE

A very important element in curriculum of an Engineering student is the Practical Training.

I under went practical training at SURATGARH THERMAL POWER STATION from

25-05-205 to 2!-0"-205. This is a part of total #0 days training program incorporated in

the curriculum of swami $eshvanand institute of techonology%management and gramothan

for &.Tech. courses.

As I am a student of mechanical engineering% so the training at '.T.P.'. has (een particularly

(eneficial for me. I saw the various procedures% processes and e)uipment used in production

of electricity (y thermal power which were studied in (oo$s and this has helped me in (etter

understanding of power generation and various thermal concepts.

'.T.P.'. is a very large plant and it is very difficult to ac)uire complete $nowledge a(out it in

a short span. I have tried to get ac)uainted with overall plant functioning and main concepts

involved therein.

I have summari*ed all the things% which I saw + learned at '.T.P.'. in this training report.

5. ELECTRICITY GENERATION

IndiaDs >F power amounting to "!57 in a total of ;">7 comes from Thermal

Power 'tation. In general it (urn fuels and use the resultant heat to raise steam which drive

the tur(o generator.

'TP' is a coal fired power station. The other raw materials are air and water. The coal%

(rought to the station (y trains %travels from the coal handling plant (y conveyor (elt to

the coal (un$ers% from where it is fed to the pulversing mills 2 which grind it as fine as face

powder. The finely powdered coal mi,ed with pre-heated% air is then (lown into the (oiler !

(y a fan called Primary Air 4an # where it (urns% with additional amount of air called

secondary air supplied (y a 4orced draft 4an #A. As the coal has (een ground so finely the

resultant ash is also a fine powder. 'ome of it (inds together to form lumps which fall intothe ash pots at the (ottom of the furnace. The water )uenched ash from the (ottom of the

furnace is conveyed to pits > for su(se)uent disposal or sale. ost of ash% still in fine

particle form is carried out of the (oiler to the Precipitators # as dust% where it is trapped

(y electrodes charged with high voltage electricity. The dust is then conveyed (y water to

disposal areas ! or to (un$ers for sale5 while the cleaned fuel gases pass on through

I./.4an to (e discharged up the 9himney ".

eanwhile the heat released from the coal has (een a(sor(ed (y many $ilometers of

tu(ing which line the (oiler walls. Inside the tu(es is the &oiler feed water which is

transformed (y the heat into steam at high pressure and temperature. The steam% super heated

in further tu(es passes to the tur(ine " where it is discharged through no**les on the tur(ine(lades. Cust as the energy of the wind turns the sails of the wind-mills% so the energy of

steam% stri$ing the (lades% ma$es the tur(ine rotate.

(I TURBINE !"

'team tur(ine is a rotating machine which 9?=E6T' EAT EE68@ ?4 'TEA T?

E9AI9A3 EE68@.

In India% steam tur(ines of different capacities% varying from 5 7 to 500 7% are

employed in the field of thermal power generation. The design% materials% au,iliary systems

etc. vary widely from each other depending on the capacity and manufacturer of the sets.

B+,*) -%*#)*-/,!The Thermal Power Plants with steam tur(ine uses 6an$ine cycle. 6an$ine cycle is a vapour

power cycle having two (asic characteristicsG

. the wor$ing fluid is a condensa(le vapour which is in li)uid phase during part of the

cycle and

2. The cycle consists of a succession of steady flow processes% with each processes

carried out in a separate component specially designed for the purpose. Each

constitute an open system% and all the components are connected in series so that as

the fluid circulates through the power plant each fluid element passes through a cycle

of mechanical and thermodynamic stages.

The tur(ine is of tandem compound design with separate P% IP and 3P cylinder. The P +

IP tur(ines are of single flow type while 3P tur(ine is of dou(le flow typeH the tur(ine iscondensing type with single reheat. It is (asically engineered on reaction principle with

throttle governing. The stages are arranged in P% IP and 3P tur(ines% driving alternating

current full capacity Tur(o generators.

TURBINE COMPONENTS

C+,*#0 &% C*#'/%,!

A casing is essentially a pressure vessel which must (e capa(le of

withstanding the ma,imum wor$ing pressure and temperature that can (e produced within it.

The wor$ing pressure aspects demand thic$er and thic$er casing and the temperature aspectsdemand thinner and thinner casings.

. .P Tur(ine 9asingG The principal parts of the P tur(ine casing are and a,ially

split inner shell% enclosing the rotor and outer shell of a (arrel-type construction. The

(arrel type of cylinder construction ensures symmetry of the wall thic$ness around

the a,is of rotation and hence the wall thic$ness itself is relatively less than that used

in other type of construction.

2. I.P. Tur(ine 9asingG The IP tur(ine is split a,ially and is of single shell design. The

outer casing accommodates a dou(le flow inner casing. The steam coming from the

reheater is passed into the inner casing via admission

(ranches which are symmetrically arranged in the top and (ottom halves of the outer

casing.

#. 3.P Tur(ine 9asingG The 3P tur(ine is of dou(le flow type. The casing is of triple

shell% fa(ricated construction. The outer casing consists of the front and rear end

walls% two longitudinal girders and a top cover. The inner shell of the inner casingacts as the guide (lade carriers for the initial stages of the tur(ine. The guide (lade

carriers of the 3P stage groups are so designed that% together with the inner casing%

they form annular ducts which are used for e,tractions.

:. CONCLUSION

It was really worth spending #0 days at 'TP'% 'uratgarh as I went through Electricity

8eneration. The practicality of the training was really fruitful as I was a(le to understand the

real time applications of various electronic instruments. oreover while wor$ing over there I

also gained a very rich e,perience of wor$ing in a government station as well as people. It

also gave me the $nowledge of professional fields.

It was a memora(le e,perience for me to wor$ in the station as I have (een listening to it

from my childhood.

I have learned all a(out the wagon% wagon-tippler% side-arm-charger% conveyor% rootery-vecor

% &oiler% Tur(ine% Transformer and 8enerator.

'.T.P.'. is a very large plant and it is very difficult to ac)uire complete $nowledge a(out it in

a short span. I have tried to get ac)uainted with overall plant functioning and main conceptsinvolved therein.
