To generate electricity, the gas turbine heats 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 gas turbine can be used in combination with a steam turbine—in a combined-cycle power plant—to create power extremely efficiently.
Fast fact
The GE 7F.05 gas turbine generates 225 MW, equivalent to 644,000 horsepower, or the power of 644 Formula One cars.

Rotations per minute (RPM); speeds vary by GE Vernova gas turbine design.
6B = 5163
6F = 5231
GT13E2 = 3000
7E/7F/7HA = 3600
9E/9F/9HA = 3000
LM6000PC = 3600
LM2500/LM2500XPRESS = 3600
TM2500 = 3000 (60 Hz)/3600 (50 Hz)
While both machines are considered internal combustion engines that convert a fuel into mechanical energy, they differ in how they operate and the applications where they are used.
A gas turbine mixes compressed air with either natural gas or liquid fuels (Diesel or aviation fuel) then ignites it, producing high-speed exhaust gases that rotate turbine blades connected to a shaft that powers a generator or other machinery. They are used in large-scale power generation and aviation/marine propulsion systems.
A gas engine uses either spark or compression ignition on natural gas, biogas, propane, or liquid gasoline/Diesel fuel to push pistons inside cylinders. They can be used in electricity generation, industrial cogeneration, and transportation (buses, trucks) applications.
As with most types of heavy machinery, a gas turbine’s operational lifespan depends on how well it is both constructed and maintained. Gas turbines have comparatively long lifespans because they tend to operate continuously and have fewer moving parts.
While this timeframe can’t be distilled down to a specific number, gas turbines can operate continuously if they are inspected every 4000 hours to help ensure that worn bearings/rotors or damaged blade tips aren’t causing excessive vibration. Turbines should also be overhauled every 25,000 to 50,000 hours, depending on service.
