What are the 4 main parts of a turbine?
The makeup of a wind turbine can range depending on the maximum output, but each usually consist of four main wind turbine parts:
- Generator (Nacelle)
- Rotor blades.
- Tower.
- Foundation.
What are the parts of a turbine called?
A wind turbine consists of five major and many auxiliary parts. The major parts are the tower, rotor, nacelle, generator, and foundation or base. Without all of these, a wind turbine cannot function. The foundation is under the ground for the onshore turbines; it cannot be seen because it is covered by soil.
What is a rotor in a turbine?
The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity.
What is principle of steam turbine?
In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. As that steam flows past a turbine’s spinning blades, the steam expands and cools.
What is the difference between rotor and armature?
In a generator and a motor, a rotor rotates and the stationary part of the motor is known as a stator. Similarly an armature carries current while field windings produce the magnetic field needed to excite the generator and the motor.
What is difference between stator and rotor?
The term, “stator” is derived from the word stationary. The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electro-magnets arranged around a cylinder, with the poles facing toward the stator poles.
Why condenser is kept in vacuum?
A vacuum is maintained in the condenser so that steam can easily flow and more work can be extracted from the steam in the turbine; this is the reason why vacuum is maintained in condensers. Therefore, some methods must exist to initially cause a vacuum to exist in the condenser.
What is gland condenser?
Gland Condenser is used to collect condensate and calories of steam that used for sealing steam turbine, and it also creates a state of vacuum to help discharge of steam. The thermal energy is transformed to the kinetic energy as steam of high pressure-high temperature rotates steam turbine.
What is purpose of commutator?
On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What are the components of a steam turbine?
the main parts of a steam turbine are (1) the rotor that carries the blading to convert the thermal energy of the steam into the rotary motion of the shaft, (2) the casing, inside of which the rotor turns, that serves as a pressure vessel for containing the steam (it also accommodates fixed nozzle passages or stator vanes through which the steam …
Why steam turbines are preferred over steam engines?
The superheated steam entering the turbine loses its pressure (enthalpy) moving through the blades of the rotors, and the rotors move the shaft to which they are connected. Steam turbines deliver power at a smooth, constant rate, and the thermal efficiency of a steam turbine is higher than that of a reciprocating engine.
How do you start of steam turbine?
– Start the gland steam condenser fan unit. 15. – Provided both lubricating and control oil pressure is established the startup sequence may continue at a steady even acceleration rate of approximately 300 rpm to normal running speed. – Checks should continue to be made on oil pressure, temperature and vibration readings.
Is there a better alternative to the steam turbine?
• Gas turbines can deliver either torque or thrust as the work output, while steam turbines almost all the time delivers torque as the work output. • The efficiency of the gas turbines is much higher than the steam turbine due to higher operating temperatures of the gas turbines.
