Which rotor is used in thermal power plant?

Which rotor is used in thermal power plant?

Which of the following rotor is used in thermal power plants? Cylindrical rotor is also called as round rotor or smooth rotor, there is no projection, there a closed portion contain field winding which is distributed and unslotted portion also acts as poles .

Which types of turbine is used in thermal power plant and why?

In order to match steam production to heat demand, there are three types of steam turbine in common use for CHP plants. These three are called a back pressure steam turbine, an extraction steam turbine and a condensing steam turbine. Each type will suit a different configuration of plant.

Why condenser is used in thermal power plant?

In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.

Which of the following is used in thermal power plant?

coal
Traditional thermal power plants: also called combustion power plants, they operate with energy produced by a steam boiler fueled by coal, natural gas, heating oil, as well as by biomass. The steam activates a turbine which, in turn, drives an alternator to produce electricity.

Why is cylindrical rotor machine used in thermal power plant?

Cylindrical rotors are used in high speed electrical machines, usually 1500 RPM to 3000 RPM. Damper windings are not needed in non-salient pole rotors. Flux distribution is sinusoidal and hence gives better emf waveform. Non-salient pole rotors are used in nuclear, gas and thermal power plants.

Which turbine is used in power plant?

The Francis turbine is the most popular type of turbine used in hydropower plants and sites with high head applications (130 to 2,000 feet).

Which fuel is used in thermal power station?

Coal is the major fossil fuel used in thermal power plants. Along with coal natural gas and petroleum are also used.

Why use coal based thermal power plant?

Nearly 50\% of the electricity generated in the world uses coal as the primary fuel. The function of the coal-fired thermal power plant is to convert the energy available in the coal to electricity. Coal power plants work by using several steps to convert stored energy in coal to usable electricity.

What is difference between salient pole and cylindrical rotor?

non-salient pole rotors are used in nuclear, gas, and thermal power plants. The last difference between salient pole and cylindrical pole is that the rotor of the cylindrical pole can run at a higher rotational speed, provided that the rotor is easily balanceable and the centrifugal force can be equally distributed.

How does a thermal power plant work?

How does Thermal Power Plant work? 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. This steam is used to rotate the turbine blade turbine shaft is connected to the generator.

What is therthermal power plant?

Thermal Power Plants also called Thermal Power Generation Plant or Thermal Power Station. A thermal power Plant / Station is used to convert heat energy to electric power / Energy for household and commercial applications.

What is the main fuel used in thermal power stations?

Most thermal stations use coal as the main fuel. Raw coal is transported from coal mines to a power station site by trucks, barges, bulk cargo ships, or railway cars. Generally, when shipped by railway, the coal cars are sent as a full train of cars.

What are the main components of steam power plant?

Fundamental steam power plant components are Fuel handling plant, water treatment plant, ID fan, PA fan, Chimney, Water treatment plant, Steam Boiler system, Turbine, Mobrey Switch, Fusible Plug, Fluidized bed combustor, APH, economizer, generators, ash handling plant, dust collector system, condenser, cooling tower, feed water pump.
