Thermal power plants generate electricity by converting heat energy from combustion into mechanical energy using steam to power a turbine which drives an alternator. The document outlines the basic processes involved including:
- Fuel is combusted in a boiler to produce high pressure steam.
- The steam powers a turbine which converts the thermal energy to mechanical energy.
- An alternator converts the mechanical energy to electrical energy.
- The steam is then condensed in a condenser and recycled to the boiler through feedwater heating processes to improve efficiency.

The presentation deals with the most complex and fundamental process in a CFBC boiler. i.e., Combustion. Provides an insight into the various features in a CFBC boilers which are incorporated to enhance cpmbustion.
Simply put, coal-fired electricity generation is a five-step process:
Thermal coal (either black or brown) that has been pulverised to a fine powder is burned
The resulting heat is used to turn water into steam
The steam at very high pressure is then used to spin a turbine, connected to an electrical generator
The spinning turbine causes large magnets to turn within copper wire coils; this is called the generator
The moving magnets cause electrons in the wires to move from one place to another, creating an electrical current and producing electricity.

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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

20. Main Circuits of Thermal Power Plant
Coal and Ash Circuit
Air and Gas circuit
Feed Water and Steam circuit
Cooling Water circuit
21. Coal and Ash Circuit
Coal from the storage is fed to the boiler
through coal handling equipment for the
generation of steam.
Ash produced due to combustion of coal is
removed to ash storage through ash-
handling system
22. Air and Gas Circuit
Air is supplied to the combustion chamber of the
boiler either through forced draught or induced
draught fan or by using both.
The dust from the air is removed before supplying to
the combustion chamber.
The exhaust gases carrying sufficient quantity of
heat and ash are passed through the air-heater.
Here the exhaust heat of the gases is given to the air
then it is passed through the dust collectors where
most of the dust is removed before exhausting the
gases to the atmosphere
23. Feed Water and Steam Circuit
The steam generated in the boiler is fed to the steam prime
mover to develop the power
The steam coming out of the prime mover is condensed in the
condenser and then fed to the boiler with the help of pump
The condensate is heated in the feed-heaters using the steam
tapped from different points of the turbine
The feed water supplied from external source is passed
through the purifying plant to reduce to reduce dissolve salts to
an acceptable level
This purification is necessary to avoid the scaling of the boiler
tubes
24. Cooling Water Circuit
The quantity of cooling water required to
condense the steam is considerably high and
it is taken from a lake, river or sea
. The water is pumped in by means of pumps
and the hot water after condensing the steam
is cooled before sending back into the pond
by means of cooling towers
25. Major Parts of Steam Power Plant

3. Turbine 4. Condenser
5. Economizer 6. Air preheater
7. Induced Draft Fan 8. Forced Draft Fan
9. Chimney 10. Coal Handling Plant

13. Alternator 14. Evaporator
15. Pumps
26. 1.Boiler
Purpose: To produce steam under pressure
Types:
1. Fire Tube Boiler: Hot gases of combustion are
inside the tubes and the tubes are surrounded by
water
2. Water Tube Boiler: Water is inside the tube and
hot gases are outside the tube
One of these are used according to the requirements
(See advantages and disadvantages of both in text)
30. Boiler Furnace
It is like a chamber in which fuel is burnt to produce
heat energy
Furnace walls are made of refractory materials
such as fire clay, silica etc.
Types:
1. Plain refractory Walls: Used where furnace
temperature is not very high
2. Hollow Refractory Walls: Through which air is
circulated and used for quite high temperatures
3. Partially Water Cooled Walls: Similar to plain but a
potion of surface is covered by water tubes. It is
used for high temperature applications
31.
32. Superheater
Device used to remove the traces of moisture from saturated
steam leaving boiler tubes.
It also increase the temperature above saturation temperature
Classes:
1. Radiant Superheater: Located in the furnace between the
furnace water walls and absorbs heat from the burning fuel
through radiation
2. Convection Superheater: Located well back in boiler tube
bank. It receives its heat from flue gases through convection.
(Advantages and disadvantages on text)
33. Economizer
It absorbs heat from outgoing flue gases and
used for raising the temperature of feed
water coming from condenser
Economizer raises efficiency of boiler by 10
-12 % thus 5 – 15 % of fuel consumption is
saved
34.
35. Air Preheater
Air preheater is used to recover heat from
flue gases since entire heat can’t be
extracted by economizer
Boiler Efficiency is increased by 1% if the
avg. air temp. is increased by 20°C
36.
37. Steam Turbines
There are two types of steam turbines
1. Impulse type: Steam expands completely in
the stationary nozzles, the pressure over
the moving blades remains constant.
2. Reaction Type: Steam is expanded both in
fixed blades (nozzles) and moving blades.

40. Coal Handling
1. Coal shouldn’t be exposed to air
It pollutes the air and releases poisonous gases like
carbon monoxide
2. The coal from the heaps is moved into the plant by
means of long conveyors that are electrically
operated
There are many different types of conveyors and
coal-handling devices like screwing conveyors,
bucket elevators, grabbing bucket conveyors etc.
41.
42.
43. Coal Crusher
Before the coal is sent to the plant it has to
be ensured that the coal is of uniform size so
it is passed through the crushers
Rotary crushers are very commonly used for
this purpose as they can provide a
continuous flow of coal to the pulverizer
46. Pulverizer
Are used to smash materials into tiny
granular.
Most commonly used pulverizer is the Boul
Mill
The arrangement consists of 2 stationary
rollers and a power driven baul in which
pulverization takes place as the coal passes
through the sides of the rollers and the baul
