Is gas turbine an external combustion engine?

Most gas turbines are internal combustion engines but it is also possible to manufacture an external combustion gas turbine which is, effectively, a turbine version of a hot air engine. … When external combustion is used, it is possible to use exhaust air from the turbine as the primary combustion air.

Is gas turbine an internal combustion engine?

Gas turbines are a type of internal combustion (IC) engine in which burning of an air-fuel mixture produces hot gases that spin a turbine to produce power. … Combustion occurs continuously in gas turbines, as opposed to reciprocating IC engines, in which combustion occurs intermittently.

Is a turbine an external combustion engine?

For example, an external combustion engine would use a flame to heat water into steam, then using the steam to turn a turbine. This is different from internal combustion, like in a car engine, where the gasoline ignites inside a piston, does work, and then is expelled.

How does external combustion engine work?

An external combustion engine is a heat engine where an (internal) working fluid is heated by combustion of an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine produces motion and usable work.

What are the two main types of external combustion engine?

There are two main families of external combustion engines; steam engines which rely on expanding steam (or occasionally some other vapour) to drive a mechanism; or Stirling engines which use hot air (or some other hot gas).

Why are gas turbines not used in cars?

Power generation uses gas turbines for their high reliability / low maintenance, high maximum power and low capital cost. There is absolutely no reason to use gas turbines in cars. Piston engines are cheaper, more efficient, have better throttle response…
