Gas Turbine Fundamentals

The primary function of the compressor in a gas turbine is to compress air for combustion.

Efficiency and Performance

Higher combustion temperature increases the efficiency of a gas turbine.
Operating gas turbines at the maximum possible temperature that its construction materials can handle is desirable.
Cold air at the compressor intake increases gas turbine output.

Power Generation

The output power (power rating) of a gas turbine is determined by multiple factors.
In a simple gas turbine, power is provided by the turbine.
The combustion chamber plays a crucial role in a gas turbine, where fuel is burned to produce hot gas.

Gas Turbine Types

An industrial gas turbine is derived from the jet engines used in aircraft.
In a twin-shaft gas turbine, the combustion chamber and the engine body are separated.
A turbojet engine has a two-stage centrifugal compressor.

Turboprop Engines

A typical turboprop aircraft engine combines a gas turbine engine with a propeller.

Air Supply and Starting

An open-cycle gas turbine draws the air used to drive the turbine from the atmosphere.
A starter motor is an essential auxiliary for a gas turbine, as it is not self-starting.

Characteristics

A simple gas turbine lacks a separate compressor and turbine.
A characteristic of a single shaft gas turbine is that it has a single shaft connecting the compressor, combustion chamber, and turbine.
