How does a gas turbine generator work?
How does a gas turbine generator work?
As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.
How does a turbine generator 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 gas turbine generator?
A gas turbine is a combustion engine at the heart of a power plant that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces the electrical energy that moves along power lines to homes and businesses.
Which fuel is used in gas turbine?
Natural gas
Natural gas is the most preferred conventional fuel for propulsion of gas turbines. In view of this, it is often used as a reference fuel for comparison of the performance of gas turbine engines.
What is difference between turbine and generator?
However, turbines and generators work somewhat differently. A turbine translates forms of energy into rotation. A generator converts the rotation into electricity.
What are the 5 major parts of the gas turbine engine?
Any gas turbine engine consists of:
- An air inlet,
- Compressor section.
- Combustion section.
- Turbine section.
- Exhaust section.
- Accessory section.
What are the two categories of gas turbine?
Two basic types of turboprop engine are in use: fixed turbine and free turbine. The fixed turbine has a mechanical connection from the gas generator (gas-turbine engine) to the reduction gear box and propeller. The free turbine has only an air link from gas generator to the power turbines.
What is gas turbine cycle?
The basic operation of the gas turbine is a Brayton cycle with air as the working fluid: atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature …
Can a gas turbine run on diesel?
Most common ones are naphtha, kerosene, and diesel fuels, which normally can be used as is or with minor cleanup. Oils: Includes crudes and other refined residuals that are heated to acceptable levels to enable the needed viscosity for gas turbine combustion.
