What is called Turbine?
A turbine ( or ) (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning “turbulence”) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.
Where is turbine used?
A turbine is a device that harnesses the kinetic energy of some fluid – such as water, steam, air, or combustion gases – and turns this into the rotational motion of the device itself. These devices are generally used in electrical generation, engines, and propulsion systems and are classified as a type of engine.
How many types of turbine are there?
There are 3 main types of impulse turbine in use: the Pelton, the Turgo, and the Crossflow turbine. The two main types of reaction turbine are the propeller turbine (with Kaplan variant) and the Francis turbine.
What is turbine power?
Turbine driven generators. Most of U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft.
What is the use of re heater in a gas turbine?
2. In gas turbine, what is the function of Re-heater? Explanation: In order to make a thermodynamic process of larger efficiency, it is shifted towards isothermal behavior.
Which fuel type can be used in a gas turbine?
One further advantage of gas turbines is their fuel flexibility. They can be adapted to use almost any flammable gas or light distillate petroleum products such as gasoline (petrol), diesel and kerosene (paraffin) which happen to be available locally, though natural gas is the most commonly used fuel.
How much fuel does a gas turbine use?
A 13,750-hp (10.26-kw) gas turbine uses approximately 3000 lb (1360 kg) of pipeline gas in the expander each start, which is approximately 62 million Btu (65.41 GJ) each start. With a gas value of $2.00 per million Btu ($1.89/GJ) LHV, this is $124 per start.
What are the characteristics of gas turbine?
Main Characteristics of Gas Turbine and Gas Engine
