PROBLEM:
Note: 3 stage ideal regenerative cycle
An ideal regenerative cycle is executed with steam generation at 9.0 MPa and 550. Before
condensation at 0.02 MPa, steam is extracted for feedwater heating first at 2.5 MPa, second
at 1.0 MPa, and last at 0.5 MPa. If the mass of the steam generated is 10 kg/s, determine the
following:
a. Schematic and Ts diagram
b. Enthalpies, kJ/kg
c. Mass of the steam extracted, kg/s
d. Heat added and rejected, kW
e. Turbine and Total Pump work, kW
Net work and Energy Chargeable, kW
