Textbook Question

Chapter 10.9, Problem 131FEP

Consider a steam power plant that operates on the regenerative Rankine cycle with one open feedwater heater. The enthalpy of the steam is 3374 kJ/kg at the turbine inlet, 2797 kJ/kg at the location of bleeding, and 2346 kJ/kg at the turbine exit. The net power output of the plant is 120 MW, and the fraction of steam bled off the turbine for regeneration is 0.172. If the pump work is negligible, the mass flow rate of steam at the turbine inlet is

(a) 117 kg/s
(b) 126 kg/s
(c) 219 kg/s
(d) 268 kg/s
(e) 679 kg/s

A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance to the turbine, the temperature is 450C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 6.3C. The boiler is sized for a mass flow rate of 20 kg/s. Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.

A 299-MW steam power plant operates on the Rankine cycle but with turbine and pump efficiencies of 90%. The steam enters the turbine at 10,000 kPa and 550°C. It discharges to the condenser at 50 kPa. Determine the power output of the turbine in MW.

The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 19 kg/s. Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency. Use steam tables. The rate at which heat is added in the boiler is 4192.12 kW. The power required to operate the pumps is 59354.47 kW. The net power produced by the cycle is -55162.35 ✪ kW. The thermal efficiency of the cycle is 13.16 %.
