P8-29 A closed feedwater heater is used in a Rankine cycle Steam leaves the boiler at 20 MPa, 600°C. Between the high and low-pressure turbines, steam at 1 MPa is extracted and delivered to the closed feedwater heater. Feedwater exits the feedwater heater at 20 MPa and the saturation temperature of the 1-MPa steam; saturated liquid condensate is fed through a steam trap back to the condenser. Steam from the second- stage turbine enters the condenser at 10 kPa, and...

Consider a steam power plant that operates on the ideal
regenerative Rankine cycle with a closed feedwater heater as shown
in the figure. The plant maintains the turbine inlet at 3000 kPa
and 3508C; and operates the condenser at 20 kPa. Steam is extracted
at 1000 kPa to serve the closed feedwater heater, which discharges
into the condenser after being throttled to condenser pressure.
Calculate the work produced by the turbine, the work consumed by
the pump, and the heat...

A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...

A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 40 kPa. At the entrance to the turbine, the temperature is 380 °C. The isentropic efficiency of the turbine is 88 %, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 5.9 °C. The boiler is sized for a mass flow rate of 17 kg/s. Determine the following values. °C m®/kg 1 kJ/kg (1)...

A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 °C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at...

A proposed steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at Pl and T1 at the rate of mi and exits at P2. A fraction () of the steam exiting Turbine 1 is diverted to an open feedwater heater while the remainder is reheated to T3 before entering Turbine 2. The condenser operates at P4. Saturated liquid exits the condenser and is fed to Pump 1. The outlet of Pump...
