Consider a regenerative Rankine cycle with one steam
extraction point using an
open feed-water heater (OFWH).
P at boiler = 5 MPa
T at turbine inlet = 600 0C
P at OFWH = 1 MPa
P at condenser = 10 kPa
All device efficiencies = 1
Solve the problem analytically step by step; find all work
interactions, heat transfers, and
the thermal efficiency.

A power plant operates on a regenerative vapor power cycle with
one open feedwater heater. Steam enters the first turbine stagge at
12 MPa, 560*C and expands to 1 MPa, 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. The net power output for the...

(REGENERATIVE CYCLE WITH ONE CLOSED AND ONE OPEN HEATER): Do not
use your Steam Tables. Refer to the H2O properties given in the
table below.
A regenerative cycle with one stage of
reheating is executed with steam expanding initially from 20 Mpaa
and 540 deg C. The reheater pressure is 10 Mpaa. The steam leaves
the reheater at 540 deg C. Steam is bled after reheating to one
CFWH and on one OFWH a pressure equal to 5 Mpaa and...

Consider a Rankine cycle with an ideal intermediate steam
pickup, one of which is open and the other is closed feed water
heaters. The steam enters the turbine at 12.5 MPa pressure and 550
degrees Celsius temperature and expands to 10 kPa condenser
pressure. The steam separated from the turbine at 0.8 MPa pressure
is sent to the closed feed water heater and the steam separated at
0.3 MPa pressure is sent to the open feed water heater. The feed...

A steam power plant operates on a regenerative Rankine cycle.
Steam enters the turbine at 6 MPa at 700 ºC and the condenser at 10
kPa. Turbine has isentropic efficiency of 85% and pumps have
isentropic efficiency of 90%. Steam is extracted from the turbine
at 0.6 MPa to heat the feedwater in an open feedwater heater. Water
leaves the open feedwater heater as saturated liquid.

A steam power plant operates on a regenerative Rankine
cycle with two feedwater heaters, one closed and one open. Steam
enters the turbine at 12.5 MPa and 550ºC and exhausts to the
condenser at 10 kPa. Steam is extracted from the turbine at 1 MPa
for the closed feedwater heater and 0.8 MPa for the open one. The
feedwater is heated to the condensation temperature of the
extracted steam in the closed feedwater heater. The extracted steam
leaves the closed...
