A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 12 MPaa, 520^∘ C and expands to 1 MPaa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 6 kPa. Saturated liquid exits the open feedwater heater at 1 MPa. For isentropic processes in the turbines and pumps, determine for the cycl

A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 14 MPa, 480^∘ C and expands to 2 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 2 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 8 kPa. Saturated liquid exits the open feedwater heater at 2 MPa. For isentropic processes in the turbines and pumps, determine for the cycle

Consider a 600-MW regenerative-Rankine-cycle steam power plant with an open feedwater heater, as shown in Fig. 9.17. The boiler pressure is 8 MPa, the extraction pressure is 1.5 MPa, and the condenser pressure is 6 kPa. The highpressure turbine inlet temperature is 820 K. The water leaving the condenser is saturated liquid. The exit state of the feedwater heater is saturated liquid. Determine the thermal efficiency of the power plant and the boiler mass flow rate (kg / s). | Numerade

Repeat Prob. 10-50 by replacing the open feedwater heater with a closed feedwater heater. Assume that the feed- water leaves the heater at the condensation temperature of the extracted steam and that the extracted steam leaves the heater as a saturated liquid and is pumped to the line carrying the feedwater. | Numerade

Water is the working fluid in an ideal regenerative Rankine cycle with one open feedwater heater. Superheated vapor enters the first-stage turbine at 14 MPa, 520^∘ C, and the condenser pressure is 6 kPa. The mass flow rate of steam entering the first-stage turbine is 90 kg / s. Steam expands through the first-stage turbine to 0.9 MPa where some of the steam is extracted and diverted to an open feedwater heater oper ating at 0.9 MPa. The remainder expands through the second-stage turbine to the
