It contains water and steam at high pressure and produces a stream for the turbine. The boiler has the capacity to convert water into steam. Coal, oil, and even solar and nuclear powers can be used to create the steam necessary to run a thermal plant. The boiler tubes which are in contact with low temperature acts as downcomers to circulate the water while the tubes which are in contact with high temperature acts as risers to carry steam. The flue gases leaving the boiler also contain some ash particles, so to reduce the air pollution, flue gases are allowed to pass through the Dust Collectors and Bag Filters to remove the ash particulates from the flue gases and are sometimes passed through the Wet Scrubbers to decrease the sulfur content from the gases. Heat exchanger receives hot steam, bled off from high-pressure turbine, to raise the temperature of the feedwater. Advantages and disadvantages of diesel power plant. It is composed of two identical sections and it removes the remaining available energy from the steam. After this, the water is condensed, and may be used again.This is known as the Rankine cycle.There are different procedures that can be used to heat the water; The temperature of cooling water increases by 5oc to 10oc as it flows through the condenser tubes. Again, we use this steam under pressure for transferring the … Thermal Power Plant consists of a whole set of steps in series for producing electricity. Introduction A steam power plant / thermal power plant is using steam as working fluid. The working fluid is water and steam. So to increase the quality of steam, steam Superheater is installed in a radiate section of a boiler to increase its temperature and dryness fraction without increasing its pressure as well as to accommodate for the transportation temperature losses. Box 1091, Johannesburg , 2000 South Africa Thermal Power Plant: Basic Introduction or Principle:. Steam power plant is a thermal power plant consists of main components and auxiliary components as well as other systems. This kind of power station is generally used around the world. It further goes to the crusher where it is crushed to a size of about 50mm. These plants in the range of 2 to 50 MW capacity are used as central stations for small supply authorities and works. Various Components of Power Plant (1) Radiation, which is the transfer of heat from a hot body to a cold body without a conveying medium, (2) Convection, the transfer of heat by a conveying medium, such as air or water and (3) Conduction, transfer of heat by actual physical contact, molecule to molecule. A thermal power plant is usually defined by the type of fuel used to heat the water and create steam. A thermal power plant is a power plant where steam is used to drive a steam turbine.

The power sector is the most common sector of industrial structures.After generating power by the power plant, it is distributed to different power stations which are connected to an electrical grid system. India is a country surprising the world with its incredible technology. The fuel is transported from mines via trains to the fuel storage facility in a power plant. The steam turbine can be of impulse or reaction turbine and sometimes combination of both. The overall efficiency of the thermal power plants is low like less than 30%. If the water fed to the boiler is not treated then it will reduce the life and efficiency of equipment by corroding the surfaces and scaling of equipment which may lead to overheating of pressure parts and explosions. different components of shell and tube type heat exchangers are tubes, tube sheet, shell and shell-side nozzles, tube-side channel and nozzles, channel covers, pass drivers and baffles. Improvements can be reached either by efficiency increment or by implementation of emission reduction measures. Your email address will not be published. Literature of the research area Thermal Power Plant Components Fuel storage facilities are not needed as in the case of the thermal power plant. This turbine is connected to an electrical generator. Economical for low initial cost other than any generating plant. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers. The shaft then rotates the generator which converts this kinetic energy into electrical energy. In thermal power plants, the heat energy obtained from combustion of solid fuel (mostly coal) is used to convert water into steam, this steam is at high pressure and temperature. Geothermal Power plant Diagram : geothermal power plant diagram 2. What are the advantages of Thermal power plant?

Power Generation from Thermal Power Plant Introduction. Land required less than a hydropower plant. Thermal power station’s working principle is “Heat released by burning fuel which produces (working fluid) (steam) from water. We all are aware with the term “Generator”. The flow sheet of a thermal power plant consists of the following four main circuits : … Let’s discuss about these factors one by one 1. A huge boiler acts as a furnace transferring heat from the burning fuel to row upon row of water tubes that entirely surround the flames. The fuel is then fed to the boiler generating a large amount of combustion heat. 4. Functions of Nuclear Power Plant 3. On heating feed water in a deaerator tank decreases the solubility of air in water, thereby removing the dissolved air from the water. A thermal power Plant / Station is used to convert heat energy to electric power / Energy for household and commercial applications. Water is kept flowing through the tubes by a pump P1. On the other hand treated water free from impurities and air is fed to the boiler drum where the combustion heat from the fuel is transferred to water to convert it into high pressure and temperature steam. Advantages of Thermal Power Station: The thermal power plant has great advantages as: The low initial cost. Number of workmen required at nuclear plant is far less than thermal plant. The exhaust gases leaving the boiler are generally at high temperature and this waste heat is extracted by installing an Economiser or Water Preheaters to preheat the feed water to the boiler and Air Preheaters to pre-heat the air coming from the Forced Draft Fan required for the combustion of fuel. A boiler is a pressure vessel which is used to generate high-pressure steam at a saturated temperature. They are: Boiler.
