A short presentation about the different components of a steam power plant. It first tells us what's a steam power plant and then explains how electricity is generated by them.
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.

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.

IN THIS PPT THERE ARE SOME WAYS OF USING TECHNIQUES TO SOLVE THE PROBLEM OF POLLUTION CAUSED BY THERMAL POWER PLANT
Thermal Power Plant or Thermal Energy (Chapter-2)Tesfaye Birara
Energy conversion is the process of changing one form of energy into another, a fundamental capability that enables modern civilization to function. It can occur in various ways, from converting the kinetic energy of wind into mechanical power through windmills to transforming solar energy into electrical energy in solar panels. This transformation is essential not just for daily usage but also for harnessing and utilizing natural resources more efficiently. In the context of rural electrification, this process plays a critical role. By converting available local energy resources into electricity, rural communities can access a stable and reliable power supply. This not only improves the quality of life but also supports economic development by powering homes, schools, businesses, and healthcare facilities. Consequently, energy conversion facilitates the broader goal of rural electrification, demonstrating the interconnection between technological innovation and societal advancement.

2. ■ Thermal Power Plant uses coal as a fuel and convert the heat energy obtained from burning of
coal into electrical energy.
■ There are various types of coal exist:
• Anthracite (CarbonContain is about 85%)
• Bituminous (CarbonContain is about 50 – 85%) – Maximum found in India
• Lignite (CarbonContain is about 35 – 50%)
• Peat (CarbonContain is about less than 35%)
■ Few Famous Coal Mine in India* –
• Chhattisgarh – Korba (Biggest coal mine in India on production capacity), Jhilmil
•West Bengal – Raniganj (2nd biggest coal mine)
• Jharkhand – Jharia, Karanpura,Giridih
• Odisha –Talchar, Rampur
• MP – Singrauli mine
•Telangana – Singareni, Kothagudem
• Maharashtra –Wardha, Ballarpur, Kampti
(*) Just for general knowledge

■ SipatThermal Power Plant (Chhattisgarh)
■ Korba SuperThermal Power Plant (Chhattisgarh)
■ Dadri NTPC (UP)
■ India’s first thermal power plant is Hussain Sagar (Hyderabad)
■ World biggest thermal power plant isTaichung (Taiwan)
4. Advantages and Disadvantages of aThermal
Power Plant –
■ Advantages:
• Less initial cost as compared to other generating stations.
• It requires less land as compared to hydro power plant.
•The fuel (i.e. coal) is cheaper.
•The cost of generation is lesser than that of diesel power plants.
■ Disadvantages:
• It pollutes the atmosphere due to the production of large amount of smoke. This is one of the
causes of global warming.
•The overall efficiency of a thermal power station is low (less than 30%).
• Requires long time for errection and put into action.
• Costlier in operating in comparison with that of Hydro and Nuclear power plants.
• Requirement of water in huge quantity.
6. ■ Coal Storage –
• Coal storage is necessary to store the coal for emergencies. If the supply of coal is stop due any
reason then the coal available in storage plant is used because the plant shouldn’t shut down.
■ Coal Handling –
• The obtained coal pieces are big in size so for proper heating in boiler, these big pieces are broken
down into small pieces and this process is known as pulverization.
• Pulverization process takes place in coal handling.
■ Boiler –
• A boiler (or steam generator) is a closed vessel in which water, under pressure , is converted into
steam.The heat is transferred to the boiler by all three modes of heat transfer i.e. conduction,
convection and radiation.
• Pyrometer is used to measure the temperature of boiler.
• Boiler efficiency is 85 - 90%
• Major types of boilers are: (i) Fire tube boiler and (ii)Water tube boiler.
7. FireTube Boiler –
The boiler is named so because the products of combustion pass through the tubes which are
surrounded by water. In the event of a sudden and major tube failure. Steam explosions may be
caused in the furnaces due to rush of high pressure water into the hot combustion chamber which
may generate large quantities of steam in the furnace. Fire tube boiler use is therefore limited to
low cost small size and low pressure plants.
8. WaterTube Boiler –
In this boiler, the water flows inside the tubes and hot gases flow outside the tube.
9. ■ Ash Handling –
• The ash obtained from the burning of coal in boiler is handled at ash handling plant and
store in the ash storage plant.
• This ash can used for the production of cement in cement industries.
■ Super heater –
• The steam obtain from the boiler has some moisture content left and to reduce this
moisture content the steam is pass through the super heater. Hence super heater is used to
reduce the moisture content from the steam.
• Flue gases are also fed to the super heater to heat them.
■ Turbine –
• It convert the heat energy into mechanical energy.
• Thermal turbine are two types –
Impulse type
Reaction type
10. ■ Condenser –
• Condenser collect the exhaust steam from the turbine and convert it into water this process
is known as condensation.
■ Economizer –
• It increase the temperature of water by using flue gases.
• Boilers are provided with economizer and air pre-heaters to recover heat from the flue
gases.An increase of about 20% in boiler efficiency is achieved by providing both
economizer and air pre-heaters
• Economizer alone gives only 10-12% efficiency increase, causes saving in fuel consumption
5-15 %.The feed water from the high pressure heaters enters the economizer and picks up
heat from the flue gases after the low temperature super heater.
■ Air Pre-heater –
• Air (Oxygen) is necessary for the fire in the boiler. So by the help of flue gases, the moisture
content from the air is reduce and then it is feed to the boiler.
• After the flue gases leave economizer, some further heat can be extracted from them and is
used to heat the incoming air for combustion
11. ■ Alternator –
• Cylindrical rotor type synchronous generator is used to convert the mechanical
energy into electrical energy.
• Cylindrical rotor type synchronous motor rotate at higher speed than salient pole
type rotor due to less number of poles.
12. Note:
■ The overall efficiency of thermal power plant is 25 – 30%
■ Thermal power plant is best suited for Base load.
■ ESP (Electrostatic Precipitators) –
• An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that
removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge.
• The basic idea of an ESP:
• Charging
• Collecting.
• Removing
• Every particle either has or can be given a charge - positive or negative.
• We impart a negative charge to all the particles in a gas stream in ESP
• Then a grounded plate having a positive charge is set up.
• The negatively charged particle would migrate to the grounded collection plate and be captured
• The particles would quickly collect on the plate, creating a dust layer.The dust layer would accumulate
until we removed it.
