What is the Mean Purpose of Use Gas Turbine?

Gas Turbine is a prime mover and its mean purpose is to drive the driven for power generation purpose 

Gas Turbines are Mostly Used for Power Generation and to run Compressors...

Mean purpose of using a gas turbine is to generate more power compared to other source by provision of electricity like water and so on , that produce a very high power-to-weight ratio, compared to reciprocating engines;Smaller than most reciprocating engines of the same power rating. Also moves in one direction only, with far less vibration than a reciprocating engine.

• Fewer moving parts than reciprocating engines.
• Low operating pressures.
• High operation speeds.
• Low lubricating oil cost and consumption.

to generate power, as an open cycle GT the starting times are very quick and therefore can be used as back up power in the grid for peaking or as a back up for renewable energy like wind and PV. In combined cycle applications the gas tubines are the most efficient way to generate power. currently this can exceed 60% already with the latest technologies

1-Power generation with generator in time less than steam turbine   (electricity)  

2- As a driver for compressors (centrifugal & axceial) or  pumps

the main purpose of the gas turbine is to drive generator in power generation, or divre  compressors in the oil and gas industry. it is a combustion machine witch transforms the heat energy into mecanical energy

We typically use Gas Turbine for Power plant to produce power by converting rotating mechanical energy to electrical energy using Generator.

the main purpose of gas turbine to rotate the generator for electric power generation. and drive to compressor   in industrial machine 

Gas turbines are rotary machines. The air is compressed to very high pressures and the temperature is increased by combustion. This in turn used to rotate the turbine. Part of this energy is used in rotating the compressor. THe rest can be used for different applications - mechanical drive (power generation, rotary machines in oil&gas industries, rotor in aircrafts) and also propulsion of aircraft.

The propulsive power of an aircraft engine depends on the velocity difference between the exhaust gas and the freestream velocity. This is achieved using gas turbines.  

The Gas Turbine is use as a prime mover and its mean purpose is to drive any load Like compressor, Generator.
