Repeat Problem 9.45 for a closed feedwater heater where the extraction steam is pumped to the boiler
Question:
Repeat Problem 9.45 for a closed feedwater heater where the extraction steam is pumped to the boiler pressure before being combined with the condenser feedwater, as shown in Fig. 9.18. Assume isentropic turbines and pumps
Problem 9.45
Consider an ideal regenerative Rankine cycle utilizing an open feedwater heater, as shown in Fig. 9.17. The turbine inlet conditions are 10 MPa and 700 K, and the condenser pressure is 10 kPa. The mass flow rate of the steam entering the turbine is 12 kg/s. Steam is extracted between turbine stages at 2.2MPa
