At present 54.09% or 93918.38 MW (Data Source CEA, as on 31/03/2011) of total

electricity production in India is from Coal Based Thermal Power Station. A coal

based thermal power plant converts the chemical energy of the coal into electrical

energy. This is achieved by raising the steam in the boilers, expanding it through

the turbine and coupling the turbines to the generators which converts mechanical

energy into electrical energy.

Introductory overview

In a coal based power plant coal is transported from coal mines to the power plant

by railway in wagons or in a merry-go-round system. Coal is unloaded from the

wagons to a moving underground conveyor belt. This coal from the mines is of no

uniform size. So it is taken to the Crusher house and crushed to a size of 20mm.

From the crusher house the coal is either stored in dead storage( generally 40

days coal supply) which serves as coal supply in case of coal supply bottleneck

or to the live storage(8 hours coal supply) in the raw coal bunker in the boiler

house. Raw coal from the raw coal bunker is supplied to the Coal Mills by a Raw

Coal Feeder. The Coal Mills or pulverizer pulverizes the coal to 200 mesh size.

The powdered coal from the coal mills is carried to the boiler in coal pipes by high

pressure hot air. The pulverized coal air mixture is burnt in the boiler in the

combustion zone.

Generally in modern boilers tangential firing system is used i.e. the coal nozzles/

guns form tangent to a circle. The temperature in fire ball is of the order of 1300

deg.C. The boiler is a water tube boiler hanging from the top. Water is converted to

steam in the boiler and steam is separated from water in the boiler Drum. The

saturated steam from the boiler drum is taken to the Low Temperature

Superheater, Platen Superheater and Final Superheater respectively for

superheating. The superheated steam from the final superheater is taken to the

High Pressure Steam Turbine (HPT). In the HPT the steam pressure is utilized to

rotate the turbine and the resultant is rotational energy. From the HPT the out

coming steam is taken to the Reheater in the boiler to increase its temperature as

the steam becomes wet at the HPT outlet. After reheating this steam is taken to

the Intermediate Pressure Turbine (IPT) and then to the Low Pressure Turbine

Sector. Click Here

Components of Coal Fired Thermal Power Station:

Coal Preparation

i)Fuel preparation system: In coal-fired power stations, the raw

feed coal from the coal storage area is first crushed into small

pieces and then conveyed to the coal feed hoppers at the boilers. The coal is next

pulverized into a very fine powder, so that coal will undergo

complete combustion during combustion process.

** pulverizer is a mechanical device for the grinding of

many different types of materials. For example, they

are used to pulverize coal for combustion in the

steam-generating furnaces of fossil fuel power plants.

Types of Pulverisers: Ball and Tube mills; Ring and

Ball mills; MPS; Ball mill; Demolition.

ii)Dryers: they are used in order to remove the excess moisture

from coal mainly wetted during transport. As the

presence of moisture will result in fall in efficiency due to incomplete

combustion and also result in CO emission.

iii)Magnetic separators: coal which is brought may contain iron

particles. These iron particles may result in wear and tear. The iron particles may

include bolts, nuts wire fish plates etc. so these are unwanted and so are

removed with the help of magnetic separators.

The coal we finally get after these above process are transferred to the storage

site.

Purpose of fuel storage is two –

Fuel storage is insurance from failure of normal operating supplies to arrive.



Storage permits some choice of the date of purchase, allowing the purchaser

to take advantage of seasonal market conditions. Storage of coal is primarily

a matter of protection against the coal strikes, failure of the transportation

system & general coal shortages.

There are two types of storage:

1. Live Storage(boiler room storage): storage from which coal may be

withdrawn to supply combustion equipment with little or no remanding is live

storage. This storage consists of about 24 to 30 hrs. of coal requirements of

the plant and is usually a covered storage in the plant near the boiler furnace.

The live storage can be provided with bunkers & coal bins. Bunkers are

enough capacity to store the requisite of coal. From bunkers coal is

transferred to the boiler grates.

2. Dead storage- stored for future use. Mainly it is for longer period of time,

and it is also mandatory to keep a backup of fuel for specified amount of

days depending on the reputation of the company and its connectivity.There

are many forms of storage some of which are –

1. Stacking the coal in heaps over available open ground areas.

2. As in (I). But placed under cover or alternatively in bunkers.

3. Allocating special areas & surrounding these with high reinforced

concerted retaking walls.

Boiler and auxiliaries

A Boiler or steam generator essentially is a container into which water can be fed

and steam can be taken out at desired pressure, temperature and flow. This calls

for application of heat on the container. For that the boiler should have a facility

to burn a fuel and release the heat. The functions of a boiler thus can be stated

as:-

1. To convert chemical energy of the fuel into heat energy

2. To transfer this heat energy to water for evaporation as well to steam for

superheating.

The basic components of Boiler are: -

1. Furnace and Burners

2. Steam and Superheating

a. Low temperature superheater

b. Platen superheater

c. Final superheater

Economiser

It is located below the LPSH in the boiler and above pre heater. It is there to

improve the efficiency of boiler by extracting heat from flue gases to heat water

and send it to boiler drum.

Advantages of Economiser include

1) Fuel economy: – used to save fuel and increase overall efficiency of boiler

plant.



2) Reducing size of boiler: – as the feed water is preheated in the economiser

and enter boiler tube at elevated temperature. The heat transfer area required

for evaporation reduced considerably.

Air Preheater

The heat carried out with the flue gases coming out of economiser are further

utilized for preheating the air before supplying to the combustion chamber. It is a

necessary equipment for supply of hot air for drying the coal in pulverized fuel

systems to facilitate grinding and satisfactory combustion of fuel in the furnace

Reheater

Power plant furnaces may have a reheater section containing tubes heated by hot

flue gases outside the tubes. Exhaust steam from the high pressure turbine is

rerouted to go inside the reheater tubes to pickup more energy to go drive

intermediate or lower pressure turbines.

Steam turbines

Steam turbines have been used predominantly as prime mover in all thermal

power stations. The steam turbines are mainly divided into two groups: -

1. Impulse turbine

2. Impulse-reaction turbine

The turbine generator consists of a series of steam turbines interconnected to

each other and a generator on a common shaft. There is a high pressure turbine

at one end, followed by an intermediate pressure turbine, two low pressure

turbines, and the generator. The steam at high temperature (536 ‘c to 540 ‘c) and

pressure (140 to 170 kg/cm2) is expanded in the turbine.

Condenser

The condenser condenses the steam from the exhaust of the turbine into liquid to

allow it to be pumped. If the condenser can be made cooler, the pressure of the

exhaust steam is reduced and efficiency of the cycle increases. The functions of a

condenser are:-

1) To provide lowest economic heat rejection temperature for steam.

2) To convert exhaust steam to water for reserve thus saving on feed water

requirement.

3) To introduce make up water.

We normally use surface condenser although there is one direct contact

condenser as well. In direct contact type exhaust steam is mixed with directly with

D.M cooling water.

Boiler feed pump

Boiler feed pump is a multi stage pump provided for pumping feed water to

economiser. BFP is the biggest auxiliary equipment after Boiler and Turbine. It

consumes about 4 to 5 % of total electricity generation.

Cooling tower

The cooling tower is a semi-enclosed device for evaporative cooling of water by

contact with air. The hot water coming out from the condenser is fed to the tower



on the top and allowed to tickle in form of thin sheets or drops. The air flows

from bottom of the tower or perpendicular to the direction of water flow and

then exhausts to the atmosphere after effective cooling.

The cooling towers are of four types: -

1. Natural Draft cooling tower

2. Forced Draft cooling tower

3. Induced Draft cooling tower

4. Balanced Draft cooling tower

Fan or draught system

In a boiler it is essential to supply a controlled amount of air to the furnace for

effective combustion of fuel and to evacuate hot gases formed in the furnace

through the various heat transfer area of the boiler. This can be done by using a

chimney or mechanical device such as fans which acts as pump.

i) Natural draught

When the required flow of air and flue gas through a boiler can be obtained by

the stack (chimney) alone, the system is called natural draught. When the gas

within the stack is hot, its specific weight will be less than the cool air outside;

therefore the unit pressure at the base of stack resulting from weight of the

column of hot gas within the stack will be less than the column of extreme cool

air. The difference in the pressure will cause a flow of gas through opening in

base of stack. Also the chimney is form of nozzle, so the pressure at top is very

small and gases flow from high pressure to low pressure at the top.

ii) Mechanized draught

There are 3 types of mechanized draught systems

1) Forced draught system

2) Induced draught system

3) Balanced draught system

Forced draught: – In this system a fan called Forced draught fan is installed at

the inlet of the boiler. This fan forces the atmospheric air through the boiler

furnace and pushes out the hot gases from the furnace through superheater,

reheater, economiser and air heater to stacks.

Induced draught: – Here a fan called ID fan is provided at the outlet of boiler,

that is, just before the chimney. This fan sucks hot gases from the furnace

through the superheaters, economiser, reheater and discharges gas into the

chimney. This results in the furnace pressure lower than atmosphere and affects

the flow of air from outside to the furnace.

Balanced draught:-In this system both FD fan and ID fan are provided. The FD

fan is utilized to draw control quantity of air from atmosphere and force the

same into furnace. The ID fan sucks the product of combustion from furnace and

discharges into chimney. The point where draught is zero is called balancing

point.



Ash handling system

The disposal of ash from a large capacity power station is of same importance

as ash is produced in large quantities. Ash handling is a major problem.

i) Manual handling: While barrows are used for this. The ash is collected directly

through the ash outlet door from the boiler into the container from manually.

ii) Mechanical handling: Mechanical equipment is used for ash disposal, mainly

bucket elevator, belt conveyer. Ash generated is 20% in the form of bottom ash

and next 80% through flue gases, so called Fly ash and collected in ESP.

iii) Electrostatic precipitator: From air preheater this flue gases (mixed with ash)

goes to ESP. The precipitator has plate banks (A-F) which are insulated from each

other between which the flue gases are made to pass. The dust particles are

ionized and attracted by charged electrodes. The electrodes are maintained at

60KV.Hammering is done to the plates so that fly ash comes down and collect at

the bottom. The fly ash is dry form is used in cement manufacture.

Generator

Generator or Alternator is the electrical end of a turbo-generator set. It is

generally known as the piece of equipment that converts the mechanical energy

of turbine into electricity. The generation of electricity is based on the principle of

electromagnetic induction.

Thermal efficiency of a thermal power plant is the ratio of electrical energy

generated to the chemical energy of fuel consumed. For a subcritical plant it

is below 42% for a new plant. What a plant is generating is the plant

utilization factor. For a supercritical power plant the best thermal efficiency

may be around 45-47%.

#2#2 written by written by VaaimaiVaaimai 2 WEEKS AGO2 WEEKS AGO

Thanks. But I learnt that efficiency of thermal power plants are around 45% –

50%.

#3#3 written by written by shivanshtyagishivanshtyagi 2 WEEKS AGO2 WEEKS AGO

That is my bad, yes effieceincy of plant are 45-45% but that is

thermal efficiency i.e how much coal energy is converted into the

electric power.

For thermal power plant there is a factor called Plant load Factor

(PLF), so if a plant has installed capacity of 100 and it rums with PLF

of 90% it will produce 90MWh of instantaneous power.

On an average plf of plants are from 85-90%. Though some plants

even run of PLF higher than 100% or say 1.

#4#4 written by written by VaaimaiVaaimai 1 WEEK AGO1 WEEK AGO

Thanks again. Do you have any idea of efficiency of nuclear

power plants? If a 1000 MW nuclear reactor is installed, what

will be the power output?

#5#5 written by written by VaaimaiVaaimai 2 WEEKS AGO2 WEEKS AGO

What is the thermal efficiency of a thermal power plant? You said that Neyveli

Thermal Power Station – II is producing 1470 MW of power. Whether it

produces such amount of electricity or lesser than that? (say 60 % efficiency

means 882 MW)

#6#6 written by written by shivanshtyagishivanshtyagi 2 WEEKS AGO2 WEEKS AGO

1470 is the installed capacity of the plant.Normally thermal power

plants run on around 85-90% efficency.



#7#7 written by written by naveen ($onu)naveen ($onu) 1 MONTH AGO1 MONTH AGO

one of the most apt and brisk synopsys of a thermal power plant i have ever

read. the two diagrams at the start of modified rankine cycle and the plant

over view are the highlights. Great work sir. you have proved a valid point

again that simple logics are more important than unrequired expertise. i

would be very impressed if u could also add on super critical technology and

once through boilers which use a seperator rather than the conventional

circulation type boilers. also some some point missing are gland steam

cooler and also a note on water technology. but all together great work.
