What is the basic operation of the gas turbine?

To make it into simple wording. The gas turbine is the engine of the powerplant.

It includes three key components. 

1- Compressor. 

2- Combustion.

3- Turbine.

The compressor section increase the pressure .. thus you have more air into the combustion section which allow you to add more fuel.. thus more energy.

Once the fuel/gas is burned in the combustion section .. the hot gas will go to the turbine section and the pressure will start expanding as it is driving the turbine blades. The turbine blades rotation is the key to generating power.

the gas turbine is based on the centrifugal force is a gas turbine constitute following organs: an intake-air generator rotor or the gas is compressed air for cooling and cembustion and barage air (air labyrinth huil ) faith rotor run by an engine ignition therefore has a sertain percentage of gauze ingection atravere the ingecteures + éteincel switching on the machine is done autonome.cette commender centrifugal force allows us to tour any load.

increase the pressure of the atmospheric air in the compressor, mix the air with fuel gas in burner and igniting the mixture inside the combustion chamber and blowing it into the turbine, which generates the shaft power.
kinetic energy of the exhaust gas is converted into the rotational energy by the vanes & blades.
this energy is used to drive a train and also the coupled compressor
