Gas turbine

From Simple English Wikipedia, the free encyclopedia
Simplified diagram of a gas turbine

Agas turbine,also called acombustion turbine,is a type ofinternal combustion engine.[1]The simplest form has three main parts:

  • A rotatinggas compressor(SP in the diagram) to compress air
  • A combustion chamber, called acombustor(KS in the diagram) where fuel is injected
  • Aturbine(TG in the diagram) on the same shaft as the compressor

The diagram shows a single-shaft gas turbine. One turbine drives both the compressor and the load, such as anelectric generator.There are also two-shaft gas turbines, with separate turbines to drive the compressor and the load. Two-shaft turbines are better for driving road and rail vehicles because they can give moretorqueat low speed.
