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...

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...

b) A steam regenerative cycle, shown below, is delivering 100 MW of power. Steam from the boiler is supplied to the turbine at 8 MPa, 400°C. After expanding isentropically in the 1st stage turbine to a pressure of 1 MPa, steam is taken to the reheater where its temperature is raised back to 400°C and supplied to the 2nd stage turbine. Expansion in the 2nd stage turbine is also isentropic to a pressure of 400 kPa, where a fraction (y...

Consider a reheat-regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater. Steam enters the first turbine at 8.0 MPa, 500°C and expands to 0.8 MPa. The steam is reheated to 500°C before entering the second turbine, where it expands to the condenser pressure of 10 kPa. Steam is extracted from the first turbine at 2 MPa and fed to the closed feedwater heater. Feedwater leaves the closed heater at 200°C and 8.0...

C and D please.
AGL Energy is expanding the capacity of the Liddell Power Station. The plan is to commission a steam turbine power plant that operates on a regenerative Rankine cycle and has a net power output of 150 MW where steam enters the turbine at 10 MPa and 500°C, and the condenser at 10 kPa. The isentropic efficiency of the turbine is 80 percent, and that of the both pump is 95 percent. Steam is extracted from the...

SP-25 Consider a regenerative steam power plant with one open feedwater heater and one closed feedwater heater. Superheated steam enters the turbine with a mass flow rate of 120 kg/s at 16 MPa and 560°C (State 1). Some fraction of the steam is extracted at 40 bar (State 2) and is supplied to the closed feedwater heater. The remaining steam expands to a pressure of 3 bar (State 3), another fraction is extracted at this pressure, and is supplied to...
