Consider a cogeneration steam power plant that operates on a reheat Rankine cycle as shown in Figure 1. Meanwhile Figure 2 shows the T – s diagram of the plant. The plant is able to produce turbines power output of 8500 kW and supplies 3000 kW of process heat. Two units of turbines have been used in the plant namely high-pressure and low-pressure turbines. Superheated steam enters the high-pressure turbine at 8 MPa, 400 °C and the low-pressure turbine at 1.4 MPa, 400 °C of pressure and temperature, respectively. The steam is extracted at the end of the high pressure turbine to be used in process heater and leaves the process heater as saturated liquid then enters the mixing chamber. The remaining of steam from the high-pressure turbine is reheated to 400 °C and the steam leaves the condenser as a saturated liquid of 10 kPa. The isentropic efficiency of the turbines and pump are neglected in analyzing the system

Water is the working fluid in an ideal Rankine cycle with regeneration. All steam enters the first turbine stage at 12 MPa, 520 °C and expands to 1 MPa where some of the steam is extracted and diverted to the open feedwater heat exchanger operating at 1 MPa. The remaining steam keeps expanding through the second turbine stage and exits at 6 kPa, then goes through a heat exchange to cool to saturated liquid water. After that, the pump increases the pressure back to 1 MPa. Then it goes to the feedwater heat exchanger. Satureated liquid water leaves the feedwater heat exchanger then pumped back to 12 MPa.

Required information. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.
