What is the meaning of turbogenerator?
Definition of turbogenerator : an electric generator driven by a turbine.
How is electricity generated from a turbogenerator?
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.
How do turbogenerators work?
The turbo generator works on the Electromagnetic Induction principle. Once this turbine is connected to the electrical generator then kinetic energy (K.E) of the vapor drives in opposition to the fan-type blades in the turbine, thus the rotor in the electrical generator will rotate and generate electricity.
What is the function of regenerator?
What is the function of regenerator? Explanation: Regenerator is usually of shell and tube construction. Regenerator uses the heat of exhaust gas to heat compressed air before it is sent to combustion chamber. This reduces the fuel consumption and improves the cycle thermal efficiency.
Why is regeneration used in gas turbine?
Regeneration is also a procedure utilized to increase the thermal efficiencies of both the simple gas turbine and the steam turbine cycles. Another important procedure to increase the thermal efficiency of the power plant cycle is the combined cycle, which consists of a gas turbine and a steam turbine cycles [1] [2] .
What is gas turbine regeneration?
What is regeneration in gas turbine? Regeneration in gas turbines is the recycling process in which heat energy loss with exhaust gases from the turbine is utilized to heat the air after compression.
Why is it called a gas turbine?
gas-turbine engine, any internal-combustion engine employing a gas as the working fluid used to turn a turbine. The term also is conventionally used to describe a complete internal-combustion engine consisting of at least a compressor, a combustion chamber, and a turbine.
Is a gas and steam turbine same?
The primary difference between steam and gas turbines is the fact that steam turbines receive power from expanding steam. Fuels such as natural gas can heat condensed water in a boiler, but it’s also possible to utilize renewable thermal energy for this heating.
Which is more efficient gas or steam turbine?
The relatively simple design of the steam turbine makes it more efficient to maintain. A steam turbine also offers up to 90 percent efficiency, and sometimes above, for industrial steam turbines. This makes steam turbines the most efficient in most types of applications.
What are gas turbines made of?
The majority of gas turbines are made from nickel-based alloys, however current running temperature of the gas turbine (1350°C) is often in excess of the melting point of these Nickel alloys (1200~1315°C)! In order to overcome this problem, two main advancements have been adopted.
What is a gas turbine regenerator?
Regenerators can be used for exhaust-gas heat exchange or for intercooling in gas-turbine systems. As an exhaust-gas heat exchanger, a regenerator recovers heat from the exhaust and uses it to preheat the compressed air before the compressed air enters the combustor.
What is reheating in gas turbine?
Explanation: Reheating in Gas Turbine: Reheating is a method of increasing the mean temperature of heat reception. In this, the gas is again heated after it has expanded in the gas turbine.
What is a turbogenerator?
In conventional thermal power plants another step is added: the conversion of chemical energy by combustion into mechanical energy to drive either a steam or a gas turbine. High-speed generators for these power plants are called turbogenerators or turbine generators.
What is gas turbine?
Today, gas turbines are one of the most widely-used power generating technologies. Gas turbines are a type of internal combustion (IC) engine in which burning of an air-fuel mixture produces hot gases that spin a turbine to produce power. It is the production of hot gas during fuel combustion, not the fuel itself that the gives gas turbines
When was the first turbo generator made?
The first turbo-generators were electric generators powered by water turbines. The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866; industrial-scale production with dynamo generators started only in 1883.
How does a hydrogen turbo generator work?
The hydrogen gas is circulated within the rotor enclosure, and cooled by a gas-to-water heat exchanger. ^ For the purposes of this article, the term turbo generator means the electrical machine that converts mechanical power from a rotating turbine shaft to electrical power.
