The ans is with respect to Thermal Power plants: the basic difference between a 500MW plant and 600MW palnt is in the turbine design. the 600MM turbine has 1 HPT, 1IPT and 2 LPTs, 2 Condensors and a generator. the 500MW turnbine has 1 HPT, 1IPT and 1 LPT, 1 condensor and a generator. HPT: high pressure turbine IPT: intermediate pressure turbine LPT: low pressure turbine
In a thermal power plant, water is heated in a boiler to produce steam.This steam turns the shafts of a turbine.the thermal energy of the steam is converted into mechanical energy at the turbine.The turbine is coupled with an alternator.In the alternator, the mechanical energy of the turbine is converted into electrical energy.
A geo thermal power plant uses the heat provided deep below the earths surface combined with water to create super heated steam, which then powers a turbine to produce electricity. Geothermal plant is a power plant using thermal energy from underground to boil the water and pass through turbine producing electricity.
Should a power plant where the prime mover is a gas turbine be categorized as a thermal power plant?
The energy in coal is stored as chemical potential energy. When the coal is burned, this chemical energy is converted to heat. The boiler converts this thermal energy into pressure of the steam. The pressure energy in the steam is then converted into rotating mechanical energy using the turbine. As the turbine spins the generator, the generator converts this into electrical energy.
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
BMCR is the boiler maximum continous rating .It is that the maximum temperature , steam flow or the pressure that is used to generate full load or the bolier can withstand. TMCR is the turbine maximum continous rating .It is that the maximum temperature , steam flow or the pressure that the turbine requires for generating full load NOTE:BMCR WILL BE MORE COMPARED TO TMCR
Steam engine is a device that transforms thermal energy into mechanical energy. An internal combustion engine (I.C Engine) can transform thermal energy into mechanical energy. In nuclear power plant also the heat energy released is used to turn the turbine and thus thermal energy is converted into mechanical energy of rotation of turbine. This mechanical energy of turbine is further converted into electrical energy in generator.
What is difference between structure of steam turbine in thermal power plant and nuclear power plant?
A Hogger is a device to remove the Air from Turbine inside for creating initial vaccume for start up the turbine means create negative pressure inside Turbine or say creates less pressure than atmospheric pressure in Turbine. An Ejector is a device used in Power plant to remove Undissolved gases from Condenser to avoid any harm to system from these gases. If any correction is required pl. correct it.
Fossil fuel like coal or natural gas is brought to the power plant by trains. Then it is burned to heat water to make steam. The steam is under pressure and it wants to escape, so it is run through a turbine and the power of steam spins the turbine. The spinning turbine runs and electric generator that makes electricity.
Thermal power plant uses heat source like burning coil, gas, wood or natural heat sources like solar heat or geysirs. Heat is transformed to vaporising water. When water turns into steam it has lot of energy(entalphy) in it. this energy is used in wanted application as turbine or central heating. Most of the energy is where the steam turns back to water. Thermal power plant usually has both electric turbine and distributional heating because of…
A turbine extracts some of the energy from a moving fluid or gas and turns it into rotational motion. In a power plant, the rotational motion drives a generator, and the generator produces electricity. If the turbine is in a hydroelectric plant, the moving fluid is river water pulled towards lower elevations by gravity. If the turbine is in a coal-fired plant, the fluid is high-pressure steam escaping from a boiler heated by the coal…
Energy in all forms (electrical, mechanical, chemical, thermal) can change from different forms. For example, consider a piece of coal in a power plant. The burning piece of coal is transforms from chemical to thermal energy. If the thermal energy (heat) boils water, it's transform to an another form of chemical energy. Then, if it turns a turbine, it's changed to mechanical energy. Then, finally, the turbine turns a generator and makes electricity (electrical energy).
Gasoline can combusted and given out thermal energy but I suspect the questing ask about thermal energy plant. Thermal energy plant usually referred to Geothermal power plant or Solarthermal power plant. Geothermal plant run on the thermal energy from earth and Solarthermal run on the solar radiation transformed to heat. If the question ask for the latter then no, thermal energy plant doesn't run on gasoline.
"Geothermal" is a word that describes (geo--geologic--earth) and (thermal--heat). Geothermal power is produced by heat from the earth. A hole is drilled deep into a thin portion of the crust of the earth, water is pumped in and superheated and the high pressure water vapor that is produced is piped into a gas turbine electrical generator producing electricity.
The problem lies in the excess amount of heat in the water, and the ability to pump hot water. Hot water has a tendency to flash into steam if it is too hot and will damage pumps when it does this. More importantly for power plants, too much heat in the water prevents the condensers from condensing steam back into water, such that it will build up heat and backpressure in the exhaust hood of…
Coal-fired thermal power plants are presently mainstream among newly-established thermal power plants in Japan. Improvement of operational characteristics with functions of following load demands and the reinforcement of environmental control measures are also required for coal fired thermal power plants. Hitachi, Ltd. has completed a unit that meets such requirements: the No. 1 unit of the Shinchi Power Station (power generation capacity: 1000 MW) of Soma Kyodo Power Company, Ltd. The unit has the world's…
Electricity is an energy that can make changes in matter, and create light, heat, or motion. It is made when fossil fuels are burned at a power plant and he pressure builds up with the smoke and it makes a turbine spin, that turbine then uses other materials such as magnets to make electricity from there.
A nuclear power plant, is a system which converts energy from one form to another, involving many steps. The fuel is radioactive isotopes, in the more common boiling water reactors in the USA, the materials used are often uranium 235 and plutonium 239. When a radioactive isotope undergoes fission, it splits into two smaller atoms, releases neutrons and a large amount of thermal energy or heat. Neutrons are important because they carry the energy which…
A nuclear power plant uses thermal energy from a nuclear reactor to produce steam and drive a turbine/generator, and often has a capacity of more than 1000MWe from one reactor. I don't think there are any thermoelectric power plants, but small arrays of thermocouple devices are sometimes used to produce small amounts of power for instruments, usually in space vehicles with a radioactive source providing the thermal input.
Thermal pollution by power plants arises mainly from the approx 65 percent of the thermal energy generated which is rejected to the cooling medium via the turbine condenser. This can be rejected into a river, lake, or the sea, or to the atmosphere via cooling towers. The amount of heat rejected for a turbine of a given output is not much different for nuclear plants compared to fossil fuelled ones. Fossil fuelled plants do also…
The turbine heat rate of a steam turbogenerato is the ratio of thermal input: power generated. It is often expressed in kJ/kWh. The efficiency of the turbogenerator is simply calculated from this. The plant heat rate is the ratio of fuel energy into the plant: power generated. It is greater than the turbine heat rate, because not all of the fuel's thermal energy can be captured by the boiler, and also power station services such…
In a thermal power plant, the conversion of thermal heat into rotational energy is achieved. This can be achieved by using the thermal heat from burning coal or from burning oil or from burning gas or from steam generated by solar means (insolation). In a coal power plant the thermal heat obtained from burning coal is converted into rotational energy, which drives the generator and eventually, electrical power is generated.
