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.

A steam power plant operates on an ideal Rankine cycle with two
of its feedwater heater closed as shown in the figure below and
with a net power output of 105MW. The mass flow rate of the steam
is 70kg/s and enters the high-pressure turbine at 6MPa and
and leaves at 1.5 Mpa. a fraction of x of steam is extracted at
this pressure to the closed feedwater. a fraction of y of steam is

Consider a modern extra-supercritical pressure steam power plant that operates Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater, as shown below. Steam enters the high-pressure turbine at 32 MPa and 700 °C and is condensed in the condenser at a pressure of 10 kPa. Steam exits the high-pressure turbine at 4 MPa and is routed into a reheater (inside the boiler) to be reheated to 640 °C. Steam at P-8 MPa is extracted from...

Consider an ideal regenerative Rankine water vapor cycle with two
feed water heaters, one closed (streams do not physically mix). The
steam enters the turbine at 10MPa and 600º C, at a rate of 310kh /
s, and exits towards the condenser at 10kPa. Steam is drawn from
the turbine at 1.2 MPa (stream 9) for the closed heater and at 0.6

a) A steam power plant operates on an ideal reheat-regenerative Rankine cycle. Steam enters the high-pressure turbine (HPT) at a pressure of 10 MPa and temperature of 550°C. The steam expands through the HPT stage to a pressure of 0.6 MPa. Some of the steam at the end of the expansion process in HPT is extracted for a regeneration process in a closed-type feedwater heater. The steam leaves the heater as a saturated liquid and then is throttled to the...
