Mechanical Engineering

Taichung thermal power station wants to change their steamgenerator with a new steam generator that has a better efficiency.The existing steam generator operating with Rankine cycle withreheat and has a thermal efficiency of 30%. Taichung thermal powerstation has been offered by Patron Company that supplies new steamgenerators that are more environmentally friendly. Thespecifications of the new steam generator are as follow:

  • maximum pressure is 15MPa,
  • minimum pressure is 10kPa
  • Temperature entering the turbine is 500°C.
  • Isentropic efficiency of the pump is 85%

Taichung thermal power station wants the new steam generator tohave vapor content of the steam to exceed 90% and the steam massflow rate is 12kg/s. Evaluate:

i.                            the pressure at which the reheat cycles takes place

(12 marks, C5)

ii.                    the total rate of heat in the boiler

(4 marks, C5)

iii.                          Does the new steamgenerator have higher thermal efficiency of the cycle
than the current generator? Justify your answer.
