Also known as a “combustion turbine,” a gas turbine is a type of internal combustion engine that extracts energy from a flow of combustion gas. Using “gas” as the working medium in the energy conversion process, a gas turbine converts the chemical energy of the fuel into mechanical energy or kinetic energy.
How does a gas turbine work?
Activating the gas turbine (a type of rotary heat engine) using high-pressure, high-temperature gas produces mechanical energy that is subsequently converted into electrical energy by a generator connected to the turbine.
The power output of a gas turbine is measured in megawatts (MW), with a typical turbine in a large power plant generating more than 300 MW of electricity.
Although the use of gas turbines for electricity generation goes back to 1939, current industry applications of gas turbines include but not limited to the following:
