Efficiency of ranking cycle can be increased by
  • a)
    increasing initial steam pressure and temperature
  • b)
    increasing exhaust pressure
  • c)
    decreasing exhaust pressure
  • d)
    increasing the expansion ratio
  • e)
    increasing number of regenerative heaters
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Efficiency of ranking cycle can be increased bya)increasing initial st...
Increasing the operating pressure of the boiler, automatically raises the temperature at which boiling takes place. This raises the average temperature at which heat is added to the steam and thus raises the thermal efficiency of the cycle.
