Taichung thermal power station wants to change their steam generator with a new steam generator that has a better efficiency. The existing steam generator operating with Rankine cycle with reheat and has a thermal efficiency of 30%. Taichung thermal power station has been offered by Patron Company that supplies new steam generators that are more environmentally friendly. The specifications 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 to have vapor content of the steam to exceed 90% and the steam mass flow rate is 12kg/s. Evaluate: i. the pressure at which the reheat cycles takes place (12 marks, C5) H. the total rate of heat in the boiler (4 marks, C5) Hi. Does the new steam generator have higher thermal efficiency of the cycle than the current generator? Justify your answer.

Superheated steam at 8 MPa and 480°C leaves the steam generator of a vapor power plant. Heat transfer and frictional effects in the line connecting the steam generator and the turbine reduce the pressure and temperature at the turbine inlet to 7.7 MPa and 440°C, respectively. The pressure at the exit of the turbine is 10 kPa, and the turbine operates adiabatically. Liquid leaves the condenser at 8 kPa, 36°C. The pressure is increased to 8.6 MPa across the pump....
