Questions and Answers

What is the purpose of a regenerator in a gas turbine?

  • To improve cycle efficiency by recovering some of the heat from exhaust gases (correct)
  • To increase the amount of fuel required to produce the same load
  • To reduce the overall plant capacity
  • To cool the compressed air before it enters the combustion chamber

    • Where is the regenerator placed in the gas turbine layout?

  • After the combustion chamber
  • In the airflow before the compressor (correct)
  • In the steam boiler
  • Before the exhaust gases leave the turbine

    • How does a regenerator reduce the amount of fuel required to produce the same load?

  • By reducing the efficiency of the compressor
  • By increasing the temperature of the exhaust gases
  • By recovering heat from exhaust gases to heat the compressed air (correct)
  • By cooling the compressed air before it enters the combustion chamber
