Which of the following is NOT a part of a gas turbine?

Explanation:

Gas turbine:

• A gas turbine is a continuous-combustion, internal combustion engine.
• There are three main components:
  • Gas compressor
  • Turbine on the same shaft
  • Combustion chamber
• The basic operation of the gas turbine is a Brayton cycle.
• Fresh atmospheric air flows through the compressor which brings it to higher pressure.
• Energy is then added by spraying fuel into the air and igniting it.
• So the combustion generates a high temperature and pressure.
• This high-temperature high-pressure gas enters a turbine, where it expands.
• This produces a shaft work output in the process.
• The turbine shaft work is used to drive the compressor.
• The energy that can also be (not used for shaft work comes out in the exhaust gases) and produce thrust which is used to push aircraft.
• The purpose of the gas turbine determines the design so that the most desirable split of energy between the thrust and the shaft work is achieved.
• A separate cooling system is not required as gas turbines are open systems that do not use the same air again.
• Gas turbines are used to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and military war tanks.
