In electric power generation a combined cycle is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy, which in turn usually drives electrical generators. The principle is that after completing its cycle (in the first engine), the temperature of the working fluid engine is still high enough that a second subsequent heat engine may extract energy from the waste heat that the first engine produced. By combining these multiple streams of work upon a single mechanical shaft turning an electric generator, the overall net efficiency of the system may be increased by 50–60%. That is, from an overall efficiency of say 34% (in a single cycle) to possibly an overall efficiency of 51% (in a mechanical combination of two cycles) in net Carnot thermodynamic efficiency. This can be done because heat engines are only able to use a portion of the energy their fuel generates (usually less than 50%). In an ordinary (non combined cycle) heat engine the remaining heat (e.g., hot exhaust fumes) from combustion is generally wasted.
Combining two or more thermodynamic cycles results in improved overall efficiency, reducing fuel costs. In stationary power plants, a widely used combination is a gas turbine (operating by the Brayton cycle) burning natural gas or synthesis gas from coal, whose hot exhaust powers a steam power plant (operating by the Rankine cycle). This is called a Combined Cycle Gas Turbine (CCGT) plant, and can achieve a best-of-class real (HHV - see below) thermal efficiency of around 54% in base-load operation, in contrast to a single cycle steam power plant which is limited to efficiencies of around 35–42%. Many new gas power plants in North America and Europe are of the Combined Cycle Gas Turbine type. Such an arrangement is also used for marine propulsion, and is called a combined gas and steam (COGAS) plant. Multiple stage turbine or steam cycles are also common.

based on the partial replacement of cement with ggbs as a concern to reduce the demand for cement. this seminar is being conducted in reference to 2 important journals...on the study carried out in RC beams and plain hardened concrete. Various tests are being conducted and it reveals that upto 70% replacement can be used which gives the same result as that without replacement.
Half of the electricity produced by CEB is produced by this Lakvijaya power plant
900MW power is generated from this plant.
Coal is exported from these countries such as indonesia, south africa, and Russiya.
Coal is transported from the jetty to the coal yard and from there to the main plant by a belt system.
Water spray methods are used to maintain moisture in coal
The coal bundles coming from the coal yard are pulverized well by some machines, mixed with air and released into the boiler.
There, the thermal energy generated by the combustion is absorbed by the tubes in the boiler and turns into steam
The electricity produced by the generators connected to the turbines is transmitted to the power stations through an h2 plant.
The gas coming out of coal combustion is first removed by ESP and then the harmful sulfur dioxide in the gas is removed by a device called FGD
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Coal is used as a fuel to boil the
water.
Water is boiled to form
pressurized steam.
Pressurized steam is the force that
cause the turbine to rotate at a very
high speed.
Low pressure steam after pushing
through the turbine ,it’s going into
the condenser.
Condenser – the place where the
steam is condensed back it it’s liquid
form .Then the process is
repeated

emergency stop signal.
Suited to be used for belt breakage prevention when
running out of centre & overfeed prevention due to the
belt sway.
Emergency switch: it is present in the field. One can
operate it while some maintenance is going on.
20. DM PLANT
•The main aim of the DM Plant is to de-mineralize the
raw water coming from a water source (in this case
Kharu river nearby) from any mineral presence by
chemical dosing which may be harmful to the pipeline
and boilers.
•Cooling tower also comes under DM Plant.
21. Cooling Tower
• The warm water is taken from the
condenser tubes to about a quarter
of the way up the cooling tower.
• This breaks the water up into a
very fine spray, increasing the
surface area of the water droplets
making it easier to cool.
• The cooling tower is designed as a
natural draught chimney, drawing
cold air from outside through the
falling water.
• Cool water is collected in pond at
the bottom of the cooling tower.
• From here it is pumped back to
the condensers .
22. • To produce steam boiler converts
energy, in the form of coal, into steam
• The boiler is lined with steel tubing in
which pure boiler feed water is turned
to steam by the heat created from the
burning of coal
This plant contains two types of boilers
namely:
I. AFBC(Atmospheric Fluidized Bed
Combustion)
II. WHRB(Waste Heat Recovery Boiler)
Boiler
24. Waste Heat Recovery
Boiler(WHRB):-
In this type the products of combustion
pass through the tubes which are
surrounded by water.
Atmospheric Fluidized Bed
Combustion(AFBC):-
In this type of boiler water flows inside
the tubes and hot gases flow outside the
tubes. These tubes are interconnected to
common water channels and to steam
outlet.
BOILERS:
•The AFBC boilers have many advantages over the WHRB
boilers
•High evaporation capacity due to availability of large heating
surface.
•Better heat transfer to the mass of water.
•Better efficiency of plant owing to rapid and uniform
circulation of water in tubes.
•Better overall control.
25. This fan forces the atmospheric air
through the boiler furnace and
pushes out the hot gases from the
furnace through superheater,
reheater, economizer and air heater
to stacks.
Forced Draught (FD) Fan
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,
economizer, reheater and
discharges gas into the chimney.
Induced Draught (ID) Fan
BOILER AUXILLARY :
Primary air fans (PA) are high pressure fans used to
supply the air for the transportation of coal directly to
the furnace .
Primary air (PA) fan:-
26. ECONOMISER
Flue gases coming out of the boiler carries
lot of heat.
ECONOMISER extracts a part of heat
from the flue gases and uses for heating the
feed water.
Thus improves efficiency of plant.
Temp. inside ECONOMISER is about 315
deg c.
27. SUPER HEATER
Super heater is used to remove the moisture content
from the steam.
Super heater raises the temperature of steam above 540 degree C.
Advantages of super heater
1. Increases efficiency
2. Reduces corrosion of turbine blades.
28. AIR PREHEATER
It is used to preheat the air before entering
into furnace.
It is a heat exchanger in which some
further
heat is extracted from the flue gases and
use to heat the coming air for combustion.
32. •It is designed to trap and remove
dust particles from the exhaust
gas stream of an industrial
process.
•. Precipitators typically collect
99.9% or more of the dust from
the gas stream.

44. Circulating Water Pumps
• The circulating water pumps are used
to circulate the water from the
cooling tower to the condenser and
back again
Boiler Feed Pump
• The boiler feed pump pumps water
into the boiler, overcoming the boiler
pressure of 160 bar to achieve it
• The pump is driven by a steam
turbine or an electric motor
• It runs at 7,000 revolutions per
minute
45. Low Pressure Feed Heaters
• Feed water from the condensate
extraction pumps passes through low
pressure feed heaters. Steam is used
to heat the feed water
• After the last feed heater, the feed
water is at around 160°C.
High Pressure Feed Heaters
• With a similar purpose to the low
pressure feed heaters, the high
pressure feed heaters are the last
stage of feed water heating before the
feed water enters the boiler system at
the economizer
• Feed water leaving these heaters is at
250°C
46. Condenser
• With its useful energy spent in the
turbines the steam then passes to
condensers
• Here it is condensed back into water
and pumped back to the boiler
• This happens via a series of low
pressure and high pressure feed
heaters
Condensate Extraction Pump
• The condensate water is drawn from
the condenser by the extraction pump
and sent to the low pressure feed
heaters
Deaerator
• A deaerator is a device that is
widely used for the removal of air
and other dissolved gases from
the feed water to steam-
generating boiler.
48. Electrical switchyards are usually part of a substation
where electricity is transformed from one voltage to
another for the transmission, distribution.
48
50. TRANSFORMER
Transformer is the most
convenient device for transfer
of power from one voltage to
another voltage at the same
frequency. It works on the
principle of electromagnetic
induction.
50
Transformers are of two types:
STEP-UP TRANSFORMER –
Step-up the voltage at secondary side called step up transformer.
STEP-DOWN TRANSFORMER –
Step-down the voltage at secondary side are called step-down
transformer.
51. CT is a type of instrument transformer
that is used in power system for
measurement, detection, protection of
the system.
It is a device used to measure large
current by scaling large primary current
to a smaller , easy to measure,
secondary current.
51
CURRENT TRANSFORMER
53. A circuit breaker is an
automatically-operated electrical
switch designed to protect an
electrical circuit from damage
caused by overload or short circuit.
Its basic function is to detect a
fault condition and, by interrupting
continuity, to immediately
discontinue electrical flow.
It can make or break a circuit
either manually or by remote
under normal or fault conditions.
53
CIRCUIT BREAKER
54. •It is a disconnection switch and to
be operated on no load.
•An isolator switch is used to make
sure that an electrical circuit can
be completely de-energized for
service or maintenance
54
ISOLATOR
55. It provide electrical
isolation of the
equipment, bus bar,
and circuit from the
live parts for
maintenance
purpose.
55
USES OF ISOLATOR
56. An insulator, also called a dielectric,
is a material that resists the flow of
electric
current.
In insulating materials
alliance electrons are tightly-
bonded to their atoms.
Insulator provides necessary
insulation between line
conductor and support.
56
INSULATOR
57. LIGHTNING ARRESTER
A lightning arrester is a device used on electrical power systems
to protect the insulation on the system from the damaging
effect of lightning
USES OF LIGHTNING ARRESTER
It protect the equipment from lightning stroke.
Lightning arrester is used to provide path to
unwanted excessive currents.
57
58. BUSBAR
Conductors to which a
number of circuits are
connected called bus-Bars.
In power plants, shut down
results disconnection of
supply to a large are.
Hence to avoid shut down
the major plants should
have elaborate bus bar
arrangement with duplicate
buses.
58
60. • Fuel used is cheaper
• Smaller space is required compared to hydro power
plant
• Economical in initial cost compared to hydro plants
and running costs are less compared to gas plants or
diesel plants
• Thermal plants can be placed near load centers unlike
hydro and nuclear plants. Hence transmission of
power losses can be minimized
• Thermal plants are able to respond to the load
demand more effectively and supports the
performance of the electrical grid
ADVANTAGES OF THERMAL POWER
PLANT
61. SITE SELECTION
• Transportation network: Easy and enough access to
transportation network is required in both power plant
construction and operation periods.
• Geology and soil type: The power plant should be built in an
area with soil and rock layers that could stand the weight and
vibrations of the power plant.
• Topography: It is proved that high elevation has a negative
effect on production efficiency of gas turbines. In addition,
changing of a sloping area into a flat site for the construction
of the power plant needs extra budget. Therefore, the
parameters of elevation and slope should be considered.
62. • Water resources: For the construction and operating of
power plant different volumes of water are required. This
could be supplied from either rivers or underground water
resources. Therefore having enough water supplies in
defined vicinity can be a factor in the selection of the site.
•Population centers: For the same reasons as above, the
site should have an enough distance from population
centers.
• Area size: Before any other consideration, the minimum
area size required for the construction of power plant
should be defined.
