Turbine is a
rotary mechanical device that extract the potential energy and Kinetic energy of fluids and convert into mechanical energy
. It is a prime mover which transform the energy of working fluid in to mechanical energy of turbine shaft.
What is a turbine and how does it work?
In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn,
converts the mechanical (kinetic) energy of the rotor to electrical energy
.
What is the working 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 are the main parts of 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 …
What are four types of turbines?
While turbines can be classed as either impulse or reaction according to the way they function, there are four broad types of turbines categorized according to the fluid that supplies the driving force:
steam, gas, water, or wind.
Where is turbine used?
The work produced by a turbine can be used
for generating electrical power when combined with a generator
. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached.
What is called turbine?
A device or machine that converts the kinetic energy of a fluid
(air, water, steam or other gases) to mechanical energy.
What is connected to a turbine?
The rotor
is attached to the turbine shaft, and rotates at a fixed speed. When the rotor turns, it causes the field poles (the electromagnets) to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals.”
What are the two main types of steam turbines?
Two types of steam turbines must be considered,
condensing and noncondensing
.
What is turbine and types?
The two most common types of reaction turbines are Propeller (including Kaplan) and Francis.
Kinetic turbines are
also a type of reaction turbine. Propeller Turbine. A propeller turbine generally has a runner with three to six blades. Water contacts all of the blades constantly.
Why is steam turbine used?
Electrical power stations use large steam turbines
driving electric generators to produce most
(about 80%) of the world’s electricity. … Steam turbines can also be used directly to drive large centrifugal pumps, such as feedwater pumps at a thermal power plant.
Which turbine has highest speed?
The specific speed of
Kaplan turbine
ranges from 600 to 1000 rpm. It is a low head axial flow turbine. From the table, we can conclude that the Kaplan turbine has the highest specific speed.
What are the two types of turbines?
There are different types of turbines used in hydroelectric power plants, and each type has its own advantages and disadvantages. Turbines used in hydroelectric power plants fall into two categories:
Impulse and Reaction based
. Impulse based turbines include Pelton and cross-flow turbines.
How many types of reaction turbine are there?
Mainly
two types
of reaction turbine: ( i ) Outward radial flow reaction turbine (ii) Inward flow reaction turbine.
Which is an example of impulse turbine?
Example:
Pelton wheel turbine
. Pelton Wheel Turbine: It is a tangential flow impulse turbine in which the pressure energy of water is converted into kinetic energy to form a high-speed water jet and this jet strikes the wheel tangentially to make it rotate.
What are the parts of turbine?
The turbine components to be installed are
the tower, nacelle, hub and blades
.
