Gas Turbine

Definition - What does Gas Turbine mean?

A Gas Turbine, also known as a combustion turbine, is a type of an internal combustion engine that is used in gas power plants to produce electricity. Natural gas is used as fuel by the gas turbine to rotate the blades of the turbine and convert the mechanical energy into electrical energy. The turbine works in a closed cycle power plant.

Petropedia explains Gas Turbine

Gas turbines heat a mixture of air and fuel at very high temperatures, causing the turbine blades to spin. The spinning turbine drives a generator that converts the energy into electricity. The turbine first compresses the air and fuel mixture in a similar way like an internal combustion engine, whereby the fuel is burnt at high temperature and the gases produced help in spinning the turbine blades. Once the blades of the turbine spin, it rotates the drive shaft which is connected to the generator that has large coil windings. When the complete assembly rotates at high rpm, the generator generates the electromotive force and voltage and thus produces electricity.
