Thermal power plants generate electricity by burning coal to heat water and produce steam. The steam spins turbines that drive generators, producing electricity. They provide 65% of India's power. Coal is pulverized and burned in a boiler to heat water and produce high-pressure steam. This steam spins turbines connected to generators, producing electricity. The steam is then condensed in a condenser and recycled to the boiler as water to repeat the process. Thermal power plants have significant environmental impacts due to the air pollution produced by burning coal.
The Vindhyachal Thermal Power Station is located in Singrauli district in the Indian state of Madhya Pradesh. One of the coal-fired power stations of NTPC, it is the largest power station in India, with an installed capacity of 4,760 MW. The coal for the power plant is sourced from Nigahi mines, and the water is sourced from the discharge canal of Singrauli Super Thermal Power Station
Cogeneration operations can be improved by reducing moisture content at milling and also later using dryer with flue gases. Energy generation with sugarcane bagasse and trash has the potential to supply a substantial amount of electricity. However, this potential has not been fully developed. There is the need to develop the necessary technology (strategy and equipment) to implement trash recovery and its use as supplementary fuel to bagasse at sugarcane mills, at attractive cost and without hindering mill operations. If this can be done, it will be possible to produce electric energy around the year, selling guaranteed electricity on a profitable basis to end consumers.

IN THIS PPT THERE ARE SOME WAYS OF USING TECHNIQUES TO SOLVE THE PROBLEM OF POLLUTION CAUSED BY THERMAL POWER PLANT
Thermal Power Plant - Full Detail About Plant and Parts (Also Contain Animate...Shubham Thakur
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different fossil fuel resources generally used to heat the water. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.[1] Certain thermal power plants also are designed to produce heat energy for industrial purposes of district heating, or desalination of water, in addition to generating electrical power. Globally, fossil fueled thermal power plants produce a large part of man-made CO2 emissions to the atmosphere, and efforts to reduce these are varied and widespread.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. INTRODUCTION
• In India 65% of total power is generated by the Thermal Power
Stations.
• In thermal generating stations coal, oil, natural gas are employed as
primary sources of energy .
• A thermal power station basically work on the rankine cycle.
• Thermal power plant convert the heat energy of coal into electrical
energy.
• Coal is burnt in a boiler which converts water into steam.
• The expansion of steam in turbine produces mechanical power which
drives the alternator coupled to the turbine.
3. SOURCES
• COAL SOURCE
• WATER SOURCE
• OIL SOURCE
• GAS SOURCE
4. DEFINITION
A generating station which converts heat
energy of coal combustion into electrical energy
is known as thermal power station.
5. OPERATION MECHANISM
• The coal is brought and crushed to powder, This is feed to boiler for producing heat .
• In Boiler the water is converted to steam.
• In super heater the moisture content is removed from the steam and that steam is called super heated steam.
• The superheated steam rotates the shaft of the High pressure turbine.
• The exhausted steam is sent to preheater and the steam then rotates the intermediate pressure (IP) turbine.
• The steam from the IP Turbine is then feed to low pressure turbine.
• The turbine shaft is connected to the Generator, which produces electric Power.
• The power generated is then transmitted .
8. COAL HANDLING PLANT
Raw coal wagon – Coal is brought to the site
through a wagon as per the requirement.
Wagon tippler – The coal is unloaded from
the wagon and is transported to crusher
and for storage place through conveyor.
Junction tower - JTs are used where the conveyor
has any angular deviation.
Primary crusher – The raw coal is crushed into fine pieces of 45mm
grit. Primary crusher is also called Rotatory breaker since the coal
is crushed by rotating plate.
The stone and
unwanted coal
are rejected
9. Secondary crusher – The fine pieces
of coal is crushed into powder . (25
mm grit).
Junction Tower
Mill Bunker – The 25 mm grit coal is
crushed into very fine powder for feeding
the boiler . We will have a spare bunker for
each boiler.
Boiler
Stack & Re claimer – It
is used to store the
powdered coal for
emergency purpose.
Atmospheric air
–Through FD
fan
10. PULVERIZING PLANT
• In modern thermal power plant , coal is pulverized
• ground to dust like size and carried to the furnace in a stream of hot air.
• Pulverizing is a means of exposing a large surface area to the action of
oxygen and consequently helping combustion.
• Pulverizing mills are further classified as:
1. Contact mill
2. Ball mill
3. Impact mill
11. BOILER
• A boiler or steam generator is a closed vessel to
which water under pressure, is converted into steam.
• It is one of the major components of a thermal power
plant.
• Always designed to absorb maximum amount of heat
released in the process of combustion.
12. SUPER HEATER & RE HEATER
MOST OF THE MODERN BOILERS ARE HAVING SUPER HEATER AND RE HEATER ARRANGEMENT.
• Super heater is a component of a steam-generating
unit in which steam, after it has left
the boiler drum, is heated above its saturation
temperature.
• The super heater may consist of one or more
stages of tube banks arranged to effectively
transfer heat from the products of combustion.
• Super heaters are classified as convection ,
radiant or combination of these.
13. Re heater :
Some of the heat of superheated steam is used to rotate the turbine where it loses
some of its energy. Re heater is also steam boiler component in which heat is added
to this intermediate-pressure steam, which has given up some of its energy in
expansion through the high-pressure turbine. The steam after reheating is used to
rotate the second steam turbine where the heat is converted to mechanical energy.
This mechanical energy is used to run the alternator, which is coupled to turbine ,
there by generating electrical energy.
14. DRAFT SYSTEM
• The circulation of air is caused by a
difference in pressure, known as
Draft.
• Draft is a differential pressure b/w
atmosphere and inside the boiler.
• It is necessary to cause the flow of
gases through boiler setting It may be
–
1.Natural draft
2.Mechanical draft
15. STEAM TURBINE
• A steam turbine converts heat energy of steam into mechanical energy and
drives the generator.
• It uses the principle that steam when issuing from a small opening attains a
high velocity.
• This velocity attained during expansion depends on the initial and final heat
content of the steam.
• This difference b/w initial and final heat content represents the heat energy
converted into kinetic energy.
• These are of two types :-
1. Impulse turbine
2. Reaction turbine
16. ALTERNATOR
• Turbine and alternator are mechanical
coupled with each other.
• Alternator convert mechanical energy
of turbine into electrical energy.
• The electrical output from the
alternator is delivered to the bus bar
through transformer.
17. CONDENSER
• Which condenses the steam at the exhaust of turbine.
• It creates a very low pressure at the exhaust of turbine, this helps
in converting heat energy of steam into mechanical energy in the
prime mover.
• The condensed steam can be used as feed water to the boiler.
18. GENERATOR
• The Synchronus Generator is used to generate power by connecting the
shaft of the Turbine to the shaft of the generator which create the
magnetic flux producing Emf.
• The generated voltage will generally 33 KV to 11 KV max.
• the generated Voltage is stepped up by connecting Step up transformer
and is also used for auxilliary purpose.
19. COOLING TOWER
• Remove heat from the water
discharged from the
condenser so that the water
can be discharged to the river
or re circulated and reused.
• Air can be circulated in the
cooling towers through
natural draft and mechanical
draft.
20. ECONOMIZER
• Flue gases coming out of the boiler
carry lot of heat.
• An economizer extracts a part of this
heat from flue gases and uses it for
heating feed water.
• This use of economizer results in
saving coal consumption and higher
boiler efficiency
21. AIR PREHEATER
• An air pre heater increases the temperature of
air supplied for coal burning
• And it driven from the flue gases.
• Air is drown from the atmosphere by the force of
draft fan.
• Air preheaters may be of three types
1. Plate type
2. Tubular type
3. Regenerative type
22. ASH HANDLING PLANT
• The percentage of ash in coal varies from 5% in
good quality coal to about 40% in poor quality coal
Power plants generally use poor quality of coal .
• thus amount of ash produced by it is pretty large .
• A modern 2000MW plant produces about 5000 tons
of ash daily.
• The stations use some conveyor arrangement to
carry ash to dump sites directly or for carrying and
loading it to trucks and wagons which transport it
to the site of disposal
23. UTILISATION OF SECONDARY RAW MATERIAL (ASH)
• Construction of embankments and fills.
• Construction of road in sub-base.
• Manufacture of cement.
• Manufacture of bricks/blocks.
• Agriculture as soil amendment/source of essential plant nutrients.
24. Advantages
• The fuel used is quite cheap.
• Less initial cost as compared to other generating plants.
• It can be installed at any place irrespective of the existence of coal.
• The coal can be easily transported to the site
• It require less space as compared to Hydro power plants.
• Cost of generation is less than that of diesel power plants.
25. DISADVANTAGES
• It pollutes the atmosphere due to production of large amount of smoke and
fumes.
• It is costlier in running cost as compared to Hydro electric plants.
• Maintenance cost is more
