Acknowledgement

First I would like to thank Dr Zeeshan, for giving us the

opportunity to do an internship within the organization. For us it

was a unique experience to be in thermal power station Jamshoro

and to study an interestingworking of plant. It also helped to get

back interest in research and to have new plans for our future

career.

wewould like to thank all the people that worked at tps Jamshoro

with their patience and openness they created an enjoyable

working environment.

Furthermore we want to thank all the Engineers and workers,

with whom we did the fieldwork. We experienced great things

together At last but not least we would like to thank Sir Abdul

wajid for his kind guidance and help .He really made our work nice

and great.

Summary

Within our study,we were interested in power plant engineering

specially steam power plant.It was great opportunity for us to do

an internship at tps Jamshoro. The internship was concentrated

on mechanical parts.At the beginning we all set our goals.During

several times visit to different units of plant and being involved in

different activities we tried to achieve our learning goals.The

objective was to study all mechanical parts thoroughly and to

know the reasons of failure of unit no 4.We also participated in

mechanical workshop there. Our supervisor helped us a lot in

making good relation with workers over there.

At last this internship has given us new insights and motivation to

prepare ourselves for our future career.So as we can work on our

own skills.After this we are feeling some motivation in our selves.

Introduction

Jpcl i-e Jamshoro Power Company

Jamshoro is one of the major ele

country.It is located in district J

on the right bank of Indus river on mo

center of Hyderabad.It is called thermal power plant because

steam is used as working fluid in the prime mover.

another plant is connected with tps

plant that uses gas as working fluid.

Tps Jamshoro has maximu

power.It consist of four generating units having the specifications

given below

Unit no Installed capacity

Unit no 1 250

Power Company limited also known as tps

amshoro is one of the major electricity generating plants of our

located in district Jamshoro 5 km north west of village

on the right bank of Indus river on mohrajabal about 18 km from

of Hyderabad.It is called thermal power plant because

steam is used as working fluid in the prime mover. Near

connected with tps,the kotri gas turbine power

nt that uses gas as working fluid.

Tps Jamshoro has maximum capacity of producing 850 MW

Now a days unit number 4 is not working because the hydrogen

used for cooling of rotor of generator leaked inside and that

caused the serious damage to the generator. This unit is under

repair and soon it will be repaired. The tpsjamshoro produces

hydrogen gas for uses through its own plant situated nearby.

Description of internship

Mechanical Components :

(1) Boiler :

Boiler is major component of steam turbine power plant.It is

also called steam generator.It is the component which

generates the steam from water by transfereing heat of

combustion (of fuel) to water.This plant contains four boilers as

it has only four units.The type of boiler is water tube

boiler.(water circulates inside the tubes and furnace is below

these tubes.)

Specifications of boiler unit no 1:

Max evaporation=795,600kg/h

Steam max temp=540 C

Heating surface of SH and econmiser=17533

Furnace type=natural circulation pressurized furnace.

(2)Turbine

The turbine is prime mover ,it converts the kinetic energy of

steam into mechanical energy by rotating a shaft.There are

three types of turbine

(i)impulse (II) reaction (III) impulse reaction

The plant contains four impulse-reaction turbines with three

stages in each of them.First stage is HP turbine ,2nd stage is IP

turbine and 3rd stage is LP turbine.The stages are used to utilize

maximum amount of energy and convert it into useful work.

(2) Condenser

This component is heat exchanger and it converts steam

coming from turbine again into water and sends again into

boiler as feed water to again to be converted into steam.This

plant contains four condensers with their auxiliaries like CP.

(4)Feed water pump:

It is a device used to provide feed water coming from

condenser into boiler drum at a certain height and required

flow rate.The plant contains four feed water pump.FDP of unit

1 is centrifugal type and with power of 3800 kw,capacityof

485ton/hr and 1485rpm speed.Cooling system for pump such

as lubrication or water is also available to cool bearings and

rotating parts.

(5)Cooling tower:

The cooling tower is also called heat exchangers.These are

used to cool the hot water coming from condenser with help of

air and pump. This water also helps in cooling the pumps

bearings and other heated parts of plant.Hence this water is

circulated around the condenser and cooling tower.Cooling

towers contain number of fans that are used to suck air and

that air is passed around the tubes that contain the hot water.

(6)FD and ID fans:

These are electrically operated fans,used to force gaseous.FD

fan is used to force incoming air into furnace, travelling from

air pre heater while ID fan is used to obtain required draught.In

this power plant unit 1 contains only ID fan and all other units

contain both ID and FD fans (balanced draught).

Cause of failure of 4th unit generator.

We know hydrogen gas is used as lubricant to cool down the

rotor of generator.And tps jamshoro has its own plant to

produce hydrogen.That hydrogen leaked in the generator and

it caused a blast inside generator.And it was completely

damaged due to leakge of hydrogen as we know that hudrogen

can burnt as it is fuel of high calorific value.

Reflection On Internship:

It was such a nice experience dealing with professionals and

learning from their experience at thermal power station. We

have felt immense pleasure at our internship and were very

excited to know about different interesting procedures and the

all new equipments for us that we have seen here. We again

thanks a lot to our supervisor who has really committed

himself to us for our betterment. It was an experience which

we will never forget and it will help us in future achievements.

Conclusion:

From our internship it is concluded that thermal power station

is a place of committed personals and staff, they are working

hard to keep plants in order and are always ready for any

incidence at any point in a plant. We tried our level best to

make our time useful to every possible limit and we will be

looking forward to make an impact on our future due to this

internship.
