What is steam turbine simple definition?
: a turbine that is driven by the pressure of steam discharged at high velocity against the turbine vanes.
What is steam turbine and its types?
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.
What is the best definition of turbine?
A turbine is a machine or engine which uses a stream of air, gas, water, or steam to turn a wheel and produce power.
What is function of steam turbine?
The steam turbine generator is the primary power conversion component of the power plant. The function of the steam turbine generator is to convert the thermal energy of the steam from the steam generator to electrical energy.
What is steam nozzle definition?
The steam nozzle is a passage of varying cross-section by means of which a part of the enthalpy of steam is converted into kinetic energy as the steam expands from a higher pressure to a lower pressure. Therefore, a nozzle is a device designed to increase the velocity of steam.
How does steam spin a 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. The potential energy of the steam is thus turned into kinetic energy in the rotating turbine’s blades.
What is a steam turbine and its working principle?
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. The turbines are connected to a generator with an axle, which in turn produces energy via a magnetic field that produces an electric current.
What is turbine and types of turbine?
Turbines used in hydroelectric power plants fall into two categories: Impulse and Reaction based. Impulse based turbines include Pelton and cross-flow turbines. Reaction based turbines include three subtypes: Francis turbine, propeller turbine (bulb turbine, Straflo turbine, Kaplan turbine types), and kinetic turbine.
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 mean turbines?
A turbine is a machine that uses a moving stream of air, water, steam, or hot gas to turn a wheel to produce mechanical power. A turbine is a machine that uses a moving stream of air, water, steam, or hot gas to turn a wheel to produce mechanical power.
Why is steam turbine important?
Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator—about 85% of all electricity generation in the United States in the year 2014 was by use of steam turbines. A steam turbine connected to an electric generator is called a turbo generator.
Where is a steam turbine used?
Steam turbines are found everywhere on the planet and are used to turn generators and make electricity or create propulsion for ships, airplanes, missiles. They convert heat energy in the form of vaporized water into motion using pressure on spinning blades.
What is the working principle of steam turbine?
Working principal of steam turbine:- Steam turbine is a power machine taking overheated steam with certain temperature and pressure as its motive force, and converting the heat energy of steam to mechanical energy of rotor rotation. It is the most widely used prime mover in modern thermal power plants.
How does a steam turbine work?
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.
How does steam drive a turbine?
The high pressure steam acquired by boiling the water makes the turbine blades to rotate. When it rotates it makes the shaft to rotate which in turn connects the electric motor & it generates the electricity. The turbine blades are hit by moving steam & transfers its energy to the blade.
How does steam turbine rotate by steam?
A steam turbine generator works by heating water to extremely high temperatures until it is converted into steam, then the steam energy is used to rotate the blades of a turbine to create mechanical or rotational energy . This rotational energy caused by the high pressured steam turbine is used to generate electricity from an attached generator.
