A gas turbine extracts energy from a flow of hot gas produced by combustion of gas or fuel oil in a stream of compressed air. It has an upstream air compressor (radial or axial flow) mechanically coupled to a downstream turbine and a combustion chamber in between. "Gas turbine" may also refer to just the turbine element. Energy is released when compressed air is mixed with fuel and ignited in the combustor. The resulting gases are directed over the turbine's blades, spinning the turbine, and mechanically powering the compressor. Finally, the gases are passed through a nozzle, generating additional thrust by accelerating the hot exhaust gases by expansion back to atmospheric pressure. Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, electrical generators, and even tanks.

∙ 12y agoThe scientific principle on which generators operate was discovered almost simultaneously in about 1831 by the English chemist and physicist, Michael Faraday, and the American physicist, Joseph Henry. Imagine that a coil of wire is placed within a magnetic field, with the ends of the coil attached to some electrical device, such as a galvanometer. If the coil is rotated within the magnetic field, the galvanometer shows that a current has been induced within the coil. The magnitude of the induced current depends on three factors: the strength of the magnetic field, the length of the coil, and the speed with which the coil moves within the field.
In fact, it makes no difference as to whether the coil rotates within the magnetic field or the magnetic field is caused to rotate around the coil. The important factor is that the wire and the magnetic field are in motion in relation to each other. In general, most DC generators have a stationary magnetic field and a rotating coil, while most AC generators have a stationary coil and a rotating magnetic field.

What does hydrothermal energy mean?
Hydrothermal means, quite literaly. The process is used to produce 'green' electricity. The heat from the centre of the Earth is used to turn water into steam. The steam is then used to turn the turbine, which then turns the generator and so produces electricity.
What is the process of manufacture of nuclear energy?
Nuclear energy to produce electricity is obtained from nuclear reactors, which are assemblies of uranium rods surrounded by a moderator and which can be made to produce a chain reaction of fissioning of the active part of the uranium (U235), which produces heat. The heat output raises steam either in separate boiler units (PWR) or within the reactor pressure vessel (BWR), which is then used to drive a steam turbine/generator which operates similarly to one in a coal or gas fired plant.
What are 2 ways solar energy can be converted into other forms of energy?
Penis (PV devices) or "solar cells" - change sunlight directly into electricity. PV systems are often used in remote locations that are not connected to the electric grid. They are also used to power watches, calculators, and lighted road signs.Solar Power Plants - indirectly generate electricity when the heat from solar thermal collectors is used to heat a fluid which produces steam that is used to power generator. Out of the 15 known solar electric generating units operating in the United States at the end of 2006, 10 of these are in California, and 5 in Arizona. No statistics are being collected on solar plants that produce less than 1 megawatt of electricity, so there may be smaller solar plants in a number of other states.
What energy source does hydroelectric plant use to generate electricity?
Water is used to tun a turbine. It is used instead of using fossil fuels to burn water to turn a turbine.
What does the turbine do in a generator?
A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work.The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades, or the blades react to the flow, so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and water wheelsGas, steam, and water turbines usually have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to the British Engineer Sir Charles Parsons (1854-1931), for invention of the reaction turbine and to Swedish Engineer Gustaf de Laval (1845-1913), for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.A device similar to a turbine but operating in reverse, i.e., driven, is a compressor or pump. The axial compressor in many gas turbine engines is a common example. Here again, both reaction and impulse are employed and again, in modern axial compressors, the degree of reaction and impulse will typically vary from the blade root to its periphery.
What does a turbine produce?
A turbine is most commonly connected to a generator to produce electricity. The turbine may be turned by water falling into it, and a generator produces electricity by turning through a magnetic field.
How a wind power system produce electricity?
The wind turns a wind turbine. The turbine turns a generator.
What a generator produces?
A generator, such as the ones used in renewable energy resources, produce electricity when its turned by a turbine.
How do windmills produce electricity?
The wind turns the turbine, that then turns a generator, creating energy!
What is produced by a generator?
The general term generator is usually applied to the kind of generator that produces electricity, or electric power.
What is a turbine and how does it produce electricity?

How power plant produce electricity?
in all power plants, energy is transferred into rotational kinetic energy that turns the generator's turbine. Generator produces electricity by the mean of electromagnetic induction
How do you produce electricity from biogas?
You can use the bio gas to fuel either a steam cycle generator or a gas turbine.
How does Hydro electricity power make electricity?
the basic principle is that the kinetic energy of falling water is converted to electrical energy.the water which falls on a water turbine makes it to rotate and the generator which is coupled to it(turbine) also rotates and produces electricity.
How is potential energy changed into electricity?
For example, in a hydroelectric dam, water makes a turbine move; the turbine makes a generator move, the generator generates the electricity.For example, in a hydroelectric dam, water makes a turbine move; the turbine makes a generator move, the generator generates the electricity.For example, in a hydroelectric dam, water makes a turbine move; the turbine makes a generator move, the generator generates the electricity.For example, in a hydroelectric dam, water makes a turbine move; the turbine makes a generator move, the generator generates the electricity.
How does wind power produce electricity?
In essence, the wind turbine collects kinetic energy from the wind and transfers it to the generator. The blades on the turbine turn as the wind blows. As these blades move, they rotate a shaft connected to the rotor of a generator. The spinning magnets of the generator convert that rotational energy into electricity.
What is the relationship turbine and generator?
steam powers a turbine which drives a generator to produce electrical power
